Impending sense of something

Well, all my classes are prepped for a couple of days' absence from the scene. My Abstract students are hard at work on their latest problem set, and the Precalckers are plugging away at their second take-home exam.

All is calm.

Ever get that feeling that something big is about to break?

I've got that feeling right now. I can't put my finger on it. Maybe it's just that the next week and a half is frightfully busy: something's bound to happen.

We'll be ready, my friends. We'll be ready.

I'm new here

Parker J. Palmer's and Arthur Zajonc's The heart of higher education: A call to renewal (transforming the academy through collegial conversations) (the centerpiece of the most recent faculty Learning Circle in which I took part, and about which I've posted somewhat recently) gave me more than its fair share of things to think about. Many of its insights offered theoretical, even spiritual, enlightenment regarding teaching, but other insights were more practical and practicable.

One of the more down-to-earth suggestions offered up by one of the coauthors' colleagues (Patricia Owen-Smith, Professor of Psychology and Women's Studies in the Oxford College of Emory University) was a means of encouraging contemplative practice in the classroom simply by playing music to being each class period. Owen-Smith (pp. 157-161 in the above work) describes how several years ago she began the practice of playing 7-9 minutes of music at the outset of each class. She encouraged her students to "go within, be still, and listen to the self." While she admitted the difficulty of tying this contemplative practice to improvements in students' achievement of cognitive learning goals (as if this would be the purpose of playing the music in the first place!), she reports that

over time, I learned that the music and meditative moments had an impact on many students. Some students began to ask for guidance with their contemplation and reflection....By midsemester several students per class would mention that they looked forward to this nine-minute period of music. Some students began to bring music from their own collections that they found inspirational and important. As we neared the end of the semester, the structure of the class had changed from a group of individuals reluctantly gathered together for study to a community of friends and partners who were creating a space of introspection, quiet, and respect for the process of study and the development of self.

Once or twice a week for the past few weeks I've begun a similar practice in one of my classes. It began with my reading of an excerpt from Rilke's letters to Franz Kappus (a reading which moved one student so much she had to leave the room), and continued with a passage from Dick Leith's history of the English language. At one student's suggestion one morning we watched a scene from Harold and Maude, and the next day I read one of my own recently-written poems ("Ode to Ned Maddrell," which I penned for the last-living speaker of the Manx language). To open off on Monday (at the suggestion of another student) we'll take in one of Gil Scott-Heron's last videos.

This practice has developed naturally, in an easygoing fashion, and perhaps unsurprisingly it's happened in the most natural and easygoing section of any of my courses this semester. From Day One nearly every person in that section of Precalculus has worked well together, helping each other out and asking for help when help is needed. This natural ease with which we've worked together all term has made it hard for me to tell whether the contemplative practice has had a real effect on the esprit de corps of the class...

...but I'm not going to take any chances. The practice has definitely helped me to make connections between the intellectual and the personal, between the scientific and the humanistic. It's helped me to remain focused on what really matters, and it's helped to remind both me and my students that we do well to look for mathematics' usefulness...and to look for its beauty. Much like well-chosen low-stakes writing activities, this practice is well worth the few minutes of class time that it takes.

Beginning right away I'm going to introduce this practice in all of my classes. It can't hurt.

What effect can it have in a class like my current Abstract Algebra class, a room full of stressed-out work-wearied students representing, honestly, probably the greatest range of mathematical ability I've seen in one section since I began teaching at UNCA over six years ago? I admit here and now that I find myself frustrated at how I've managed this course. For some time now I've felt the need to slow its pace to accommodate the most modestly quick learners, but without sacrificing the true nature of the subject, a nature laden with often-abstract proofs. I don't know how much slowing the pace down has helped: several students are still struggling, and as much as I hate to leave them behind (I hate hate hate people who teach to the top ten percent), I simply must move on. Moreover, I sense that the slowness has led to frustration on the part of some of the class's quicker students, and I can feel cliquishness setting in...not a nice way to end the semester.

Maybe it'd be wise at this point to remind everyone that we all have a right to say "I'm new here": we're all free to make mistakes from time to time. After all, no one's lived this life before, and the future hits us all at the same time. But no matter how far you go, you can always turn around.

What say, folks? What are we going to make of our last five weeks or so together?

Partners in crime

I know a number of people (many former and current students, a good number of colleagues, and assorted folks I've never met) read this blog, but not many often comment publicly. Quite often, though, I get comments about it on Facebook or in my in-box.

This past week I got a note from a fellow who's teaching precalculus at an inner-city high school in Boston, using inquiry-based learning. He wrote me asking about the methods I'm using in my own precalc classes right now and shared some of his own (he's asked me not to post his notes, as they're very much works in progress). I'm very impressed! His notes are clever and engaging, offering students a scaffolding students can use to climb from the barest basics up to properties of advanced functions, logs and exponents, and trigonometry. You can read about his exploits here.

By comparison, my methods that are considerably less purely inquiry-based...he's doing pretty much straight-up Moore method with high-school students! Inventive and impactful.

Dead Zone

Today I felt like every one of my classes was a bit stuck in the mud. (Oddly enough, my morning Precalc class, often my quietest, was the most lively today.) It was all we could do to keep making forward progress in a couple of the classes, and I felt like I was beating a dead horse more than once.

What to do at such times?

The classical response, at least from instructors in content-driven disciplines: "well, we've got so much to cover that we've got to keep going..."

...but this is wrongheaded. If you press on without pause, it's not like students are going to get any more engaged, and it's not like they're going to get much out of whatever you do together, anyway. In pressing on you'll be doing so only for the sake of pressing on, and any progress you make will be illusory.

This is exactly how it felt in my second section of Precalc, and in Abstract Algebra, in both of which classes we worked with (what I thought were) some pretty neat mathematical ideas: in Precalc we solved a nontrivial optimization problem involving rational functions, and in Abstract Algebra we looked at the subgroup lattices of a couple of groups and examined the asymptotic behavior of Euler's function φ. I don't feel that either class picked up on the subtle beauty in a way they would have had they been in a more receptive mood.

Don't get me wrong: I'm not blaming my classes. Both of these classes are full of wonderful students who are generally unafraid of working together to make a healthy and supportive learning environment. (I've bragged on my Precalc peeps enough this semester for you not to know how much I care about them.) Rather, I think we've just hit that point in the semester, about 50-60% of the way through, where everybody's just DEAD.

It's the Dead Zone. Wearied by exams and essays and due dates and deadlines, overburdened by homework and quizzes and lit reviews and response papers, we're tired and jaded and not having much fun. (Believe me, kiddoes, this "we" often includes me. I apologize if I'm sometimes snappy around this time of the term; it's hard to be irrepressibly chipped every hour of every day!)

On reflection, I've thought of a two-fold healthier response to these Dead Zone doldrums:

1. Play. Put down the pen or pencil, put the paper away. Let's just think of something fun we can do with whatever it is we're working at this very moment. Optimization problems? Let's come up with some kind of crazy variation on the theme, whether we have any idea how to solve it or not. Let's set it up and see if we can work it out, like Ariadne weaving a web through the labyrinth. Are we sick to death of subgroup theorems? Let's break it all down with an explicit or example, or two, or three...let's dissect the dihedral groups until there's nothing left but individual elements...let's take it apart!

2. Reflect. The next step comes as no surprise to those who know me well: once we're done playing, let's take a minute or two to write to ourselves, if only to reflect on what we've been able to discover. Did we reach an end? How? Did we run aground? Why'd we lose our way? What's our play got to do with other problems we might encounter in mathematics and beyond? Write about it, write about how we feel about it. Hell, write about how we feel in general: why are we so dead today?

Too often affective learning goals get lost when we focus too heavily on cognitive learning goals, and that goes double for content-laden quantitative sciences. Let's try not to lose sight of our humanity, and the fragility that comes with it. Let's take care of each other as we come together to learn.

By and large all of my classes this semester are doing a marvelous job at this, and I admire them for it. I never cease to be amazed at the quality of students with whom I get to interact and learn. You're terrific people, all of you!

Reflect

After having started off two different meetings of my second section of Precalc with readings from reflective writing of some kind (see this post and this one), I invited the students to join me in bringing contemplative readings into class. Several have indicated that they enjoy this start to the class, and I look forward to seeing what the others will bring in.

Running in reverse

Recently I've had a chance to feed my undying love of linguistics. I've been reading up on the history of English and its antecedents (like Angl0-Saxon) and victims in the clash of tongues that's taken place on the British Isles since the early common era (like Cornish and Manx). The text I'm currently reading is Dick Leith's A social history of English (London: Routledge & Kegan Paul, 1983), an interesting book offering a glimpse of English's development as a social, as well as a purely linguistic, phenomenon.

More interesting than Leith's treatment of English per se are some of the observations he makes about the codification of language, and the role of "authority" in the preservation and propagation of language across time and space. A central thesis of his book is that all too often we forget that language is very much dynamic: it is ever in flux, constantly changing...and that in the end that change is not driven by grammarians or the intellectual or economic elite so much as it is by the ways in which every member of society chooses to use the language.

These are points that even the most perspicacious language-lovers among us tend to overlook. The reminders Leith offers have made me think of new (to me, at least) and "subversive" paradigms for poetry (a post on that soon, perhaps)...but they've also recalled for me the central role every member of a learning community plays in that community's advancement of knowledge, while issuing a reminder as to just how dangerous it can be to trust blindly in the authority of a textbook.

The following passage from Leith (p. 68) struck me (cf. the comments some of my precalculus students made on their last exam):

Unfortunately, many people tend to treat dictionaries with reverence: rather than being seen as a record of usage, the are often regarded as the arbiter of it, a source of enlightenment for the ignorant non-specialist. In fact, the traditional arrangement of words in dictionaries gives people a strange idea about language. The alphabetic arrangement disassociates a word from the company it keeps, presenting it as a unit isolated from context and words of similar meaning. More important, many dictionaries give the impression that words have only one meaning, to be found on the right-hand side of the page. Even the fullest dictionary, the Oxford English Dictionary (OED), which shows the whole range of meanings by citing examples of a word in use at different periods in its history, puts the meanings first, then lists the examples, thereby obscuring the process involved in deriving the meanings; for we learn the meanings of new words most efficiently by hearing them in a wide range of contexts....It is not surprising, therefore, that people often misunderstand them.

How often too we ask our math students to use their textbooks in the same way they'd use a dictionary, placing theorems and proofs before (or, more often than not, simply in lieu of) the intuition and arguments that led to those theorems and proofs in the first place? How do our textbooks obscure the many long hours of exploration and discovery that went into the derivation of the theorems that pepper the textbooks' pages? Without access to the discoverer's process of discovery, the reader is apt to feel as though a given fact or formula arises ex nihilo, and that they, the uninitiated, are not privy to its inner workings.

Food for thought. By me, it's better to let the students stumble around a bit, piecing things together for themselves as they author their own textbooks. That's just what I'll be doing when we talk about general rational functions in Precalc tomorrow...strap yourselves in!

More words of wisdom from my precalc students

Yesterday afternoon I worked for an hour with the student consultants at our university's Writing Center, helping them to understand what mathematical writing might look like, preparing them to work with students in the quantitative sciences who might come in with writing assignments from their quant courses. I was happy with the conversations we had together, and delighted by the students' energy and enthusiasm.

I shared with the consultants one precalc student's response to the midterm question in which I asked the students to describe the most meaningful learning outcome they've achieved so far this semester (see here for one response, not the one I shared at the writing center), and promised that I'd share a few more.

Let me throw a few more out there, all with a common theme. Several students, including the three quoted below, indicated experiencing the realization that mastering math is more than just memorizing formulas, and that if you stop trying to memorize every last formula but rather try to break each down and understand its inner workings, you gain immeasurably through your effort. That understanding is strengthened if math is put in a contextual matrix, placed alongside other disciplines so that its relevance becomes more apparent.

Katarina had this to say about her personal revelations:

This course is unlike any other math class I've taken. We actually discuss math in English at a level that I believe everyone in the class can understand....Instead of memorizing formulas, we play them out on the board, multiple ways, so that it is almost illogical not to understand their function and there is no need to actually memorize them....We write our answers in paragraph form, truly explaining the reason for doing them and our end result....It is so unusual to me to have math and other subjects (such as writing) overlap. My initial response was to avoid it but now I'm beginning to embrace the idea. After all, isn't UNCA's liberal arts program all about integrating many subjects in order to have a broader education?

Thomasina (who took a year off from high school before coming back to college) had this to say, upping the ante by acknowledging not just understanding, but enjoyment, and even aesthetic appreciation:

When I graduated high school, I decided that school was pointless....Read, memorize, regurgitate. That is all I was ever taught. But to understand? To break something down to its very core and build it back up, seeing every piece as they’re placed together to form a whole again. It's actually beautiful. I never got what you meant when you’d say math is beautiful, but now I get it. To have the ability to look at something complex and make it simple and tangible - it's art. And it's not just with math. It applies to everything: decisions, work, other people. Everything is a complex formula waiting to be taken apart and understood, and then put back together in a way that makes sense and feels right.

Kurt reports an experience similar to that of Katarina and Thomasina:

I've found more interest and enjoyment in something that I previously found tedious and boring and have found that I actually can relate math (including calculus) to the real world and my everyday life in ways I'd not before considered or imagined....I see this insight as far more valuable to me as a person than any one mathematical concept on its own. This is the kind of insight that changes people's lives, gives the potentially brilliant scientist a view into the potential locked up inside, or even just changes a fundamental attitude or a paradigmatic shift in thinking altogether....It's a great feeling to realize suddenly 'hey, I GET this!' and even better to find 'hey, I actually LIKE this!' I truly wish there were more classes like this one which, if not persuading one to major and work in the field, to at least open one’s eyes to the possibilities.

If a precalc course can move students to wax this rhapsodically about their learning, how much can students get from still deeper and more meaningful courses? It's up to those of us who teach to make our courses as relevant as we can.

Moo...?

As I mentioned in a post not long ago, I recently asked my Precalc students to draw comics in which the characters explain how to multiply two complex numbers. I'll showcase a few here and there in the next few days. Here's an almost sickeningly cute one by Thomasina and Urban:


Also soon to come: more excerpts from the students' midterm essays on their most meaningful learning experiences so far this course.

Author! Author!

Every person is the author of her own adventures.

This is a point I try to make to all of the students in all of my courses, in which I downplay my own authority and up-play the students'. "I've got no more claim to the truth than you do. The only difference between you and me is that I've been doing it for a few more years."

It's a point I've tried to make to my colleagues, most recently this afternoon at yet another CRTF meeting. This one was a meeting of the "Big Picture" Subgroup, at which the leaders of the other subgroups (including yours truly) were asked to make presentations on our ongoing work. I had a bit to say about our review of department responses to our "information request," and about our intended review of various ILS components.

I hope that our review will be guided by a handful of basic principles:

1. Our curriculum will function most efficiently and effectively when ILS learning outcomes and departmental learning outcomes (and the means of achieving those outcomes) are brought into fullest alignment.

2. Our curriculum will be most sustainable when the resource demands it places on faculty, staff, and students are minimized.

3. Our curriculum will offer the most rich and most meaningful learning opportunities to our students when they are allowed to plan and pursue their own courses of study, navigating course requirements that are rigorous but flexible.

This last principle places a high value on non-prescriptive curricula, featuring both general education programs and degree programs with relatively few specific requirements...programs that ask the students to play an active role in putting their own academic houses in order. I don't feel that our current curriculum features such programs.

The other day, in a hall conversation with a colleague, I referred to our role in the current system as "helicopter professors": our requirements are structured in such a way that our students' academic careers are micromanaged stringently. Students are tended to carefully, led from year to year in flocks, protected and prepared (for graduate study or real-world employment), but rarely challenged to set out on their own. Based on analysis of student behavior over the past several years, the Research and Evaluation Subgroup of CRTF discovered that only 18.5% of the courses our students take count as "free electives," taken for no purpose beyond academic exploration (such courses satisfy neither major nor ILS requirements). All other courses, all but little more than a semester, go toward putting a check in some bureaucrat's box.

"We need to make sure that our students who want to do graduate work are at least well enough prepared to get into a decent masters program," one of my department colleagues insisted at tonight's meeting. I agree, wholeheartedly. But I disagree with the means he suggests we must use to get them there. Many of our peer institutions offer much more flexible programs, with far fewer explicit course requirements, and still manage to send higher percentages of their graduates into prestigious programs. (The fact that this friend of mine is shortsightedly using graduate school enrollment as the be-all-end-all measure of an academic program's success is a topic for another post...)

More important, students completing more self-directed courses of study gain authority over their own actions. They grow in competence and confidence as they're asked to take on more responsibility for their own lives. They mature more quickly. They learn how to ask and answer important questions concerning their coursework and their careers. Forced to connect the dots for themselves, they become more authentic experts in their own disciplines.

This isn't to say we shouldn't offer our students some kind of guidance: nothing can supplant informed academic advising. Good advising can take the place of stringent requirements. If a student should wish to pursue graduate study, she should be encouraged to take courses that will most well prepare her for that study. If she fails to follow up on the advice her professors give her, she might be sunk...but she might not. She may succeed in her ambitions, but even if she doesn't...so what? Even if she doesn't end up where she'd originally set out to be, she's had a chance to plot her own path in the meantime, learning from whatever mistakes she's made on the way. Life is what it is, and each of us is who each of us is.

In my second section of Precalc (and again in my Abstract Algebra class), I read an excerpt from Rainer Maria Rilke's 6th letter to the poet Franz Kappus (Letters To A Young Poet, translated by Joan M. Burnham, Novato, CA: New World Library, 1992, pp. 53-55):

You should not be without a greeting from me at Christmastime, when in the midst of festivities your feeling of aloneness is apt to weigh more heavily upon you. Whenever you notice that it looms large, then be glad about it. For what would aloneness be, you ask yourself, if it did not possess greatness? There exists only one aloneness, and it is great, and it is not easy to bear. To nearly everyone come those hours that we would gladly exchange for any cheap or even the most banal camaraderie, for even the slightest inclination to choose the second-best or the most unworthy thing. But perhaps it is exactly in those hours when aloneness can flourish. Its growth is painful as the growing up of a young boy and sad as the emergence of springtime....Think, dear friend, reflect on the world that you carry within yourself. And name this thinking what you wish. It might be recollections of your childhood or yearning for your own future. Just be sure that you observe carefully what wells up within you and place that above everything that you notice around you. Your innermost happening is worth all your love. You must somehow work on that.

Let us reflect, my friends. What is it you find within yourself? How can you make your life your own?

Seriously, she was not paid to say this

In my last post I mentioned I'd be posting excerpts from my Precalc students' midterm exams (and a few assorted comic strips offering explanations of complex multiplication). Here's the first installment.

Tonya's always challenging me with what I believe is the best question a student can ask in a math class, a question which can be paraphrased succinctly by the words "who cares?" She's always on the lookout for relevance and applicability. "That's cool," she'll say, slightly sardonically, and then add, "but how can that be used?" I love it. Every math class should have three or four Tonyas.

Tonya's response to my midterm question asking students to indicate the most meaningful thing they've learned so far this semester was a near-perfect defense of writing-to-learn. It was a delight to read! I asked her for permission to quote her response in full, and she gave me the go-ahead.

Before letting Tonya take it home, I should note that several other students indicated the same realization (of the power of writing as a tool for discovery and for gaining understanding) as the most meaningful outcome of the course so far.

Saith Tonya:

As much as I hate to admit it I think the most beneficial thing that I have learned or rather have incorporated into my learning process during this class has been providing sort of narrative explanations for the mathematical concepts in our homework assignments. This practice really brings light to the idea that the best way to learn something is to teach it. Although laborious, time consuming, and even a bit tedious it has proven beneficial to my comprehension.

I think it may be in some way related to uniting the two sides of the brain or the two main avenues in which human beings tend to process information. It seems that people so often separate quantitative reasoning and verbal reasoning as almost dichotomic and even hierarchical in nature. The fact of the matter is however that both approaches to logic are inherent to one another. Both numbers and words are at their most fundamental level simply expressions humans use to describe the world. Thus I have found great significance in the practice of incorporating those two expressions.

In my mind (as is obvious from my questions in class) mathematics bares very little significance independent of some broader meaning or application. Being forced to go through problems step by step and constantly attend to the looming “why?” in explaining the process that leads to the solution has been instrumental in illuminating that broader meaning. Being able to explain why something was done at a certain step in the problem forces you to draw on the most rudimentary understanding of the process and ultimately universalizes the relevance of that action. I believe that this is the underlying principle behind all creative thought. It is the ability to rearrange, expound, and theorize about the world with our little tool kit of axioms if you will.

As I move forward in my professional/academic life I think it will serve me to have been denied the temptation to skip steps or overlook details in order to more readily achieve whatever end it is that I am vying for whether it be the solution to a hw problem or a policy report. It has been an exercise in demonstrating that anything whole is made up of nothing less than the sum of its parts (maybe more but definitely not less).

I love my job.

But wait, there's more...

I spent most of the day responding to my Precalc students' first midterm exams and their most recent homework. It was time-consuming, but fulfilling: the trick is asking meaningful questions. The exam included a question asking students to reflect on what it is they've learned so far this semester that will most help them meet their own personal and professional goals. The homework asked them to draw a comic strip in which the characters explain how to multiply two complex numbers.

Both of these exercises were answered with truly creative responses. I'll be sharing several of each here, once I get permission from the students to do so. For now, let it suffice to say that in their reflections many of the students report new-found appreciation for mathematics, new or renewed excitement about it, and greater confidence in working with it. As many or more gave great tips on solving problems or approaching weighty matters more critically and with greater skepticism.

I expect great things from these students. I really do have the best job on Earth.

lovin' it

I am so enamored of my second section of Precalc right now. They're so much fun, and so smart, and so engaged! Gush gush gush...here's a link to the first edition of their class newsletter (see this post from this past May, in which I talked about this project): To Infinity and Beyond (Issue #1). It's marvelous! I've got a full-color hardcopy on my desk right now, my own smiling face beaming up at me.

In all seriousness: I find myself very calm in that section. They're inquisitive and skeptical; they're not satisfied with pat answers or particular formulas; they think in big pictures and big ideas; they're reflective and resourceful; they're fun.

It's a good learning community, the healthiest class I've had in a long time in that regard. I like to think I've played some part in making it so.

Welcome!

Yesterday I ran into one of my Precalc students outside of class. I was on my way back to Robinson Hall after teaching my Abstract class over in Karpen; Becky was en route to the library with the rest of her LANG 120 class. There they'd be discussing the use of library resources in conducting research.

We chatted briefly, and I asked her if she was still considering a math major. (She was one of two in that section who, without prompting by me, indicated interest in the major at the outset of the semester.) "I definitely am," she said excitedly, and then a look of worry spread over her face, "do you think I still should?" I was a bit thrown off and only after a few seconds managed to reply with something like "of course!" She went her way and I went mine, but our encounter stuck with me. Why had she asked what she had?

I suspect it may be because she may not feel as confident in her math ability as she did at the start of the semester. Though she's done well on every homework set and on every quiz, like everyone else in the class she's made her share of mistakes and hasn't presented complete understanding of everything we've talked about. Might she believe that only those who can complete Precalculus with flawlessness and perfection are worthy of pursuing a degree in mathematics? (Only later did I think of an apt analogy: as I'm highly unlikely to ever run a four-minute mile, might I just as well give up on one of my favorite hobbies?)

After thinking it over, I found that I could understand Becky's belief, given the traditional structure of mathematics education, home to bell-curve-based grades, punctilious point-based assessment, and lecture-based teaching. There's an air of elitism to the way students are often ranked and ordered, made to fight with one another for a scant few As. The unsaid assumption in classrooms where deep and steep curves guarantee a normal distribution of grades is that only the best need move on, and that the others' services will not be needed. Detailed rubrics with single-percentage-point resolution signal to the student that mastery of fine detail takes priority over authentic understanding. (No wonder students clamber after every point, wondering what it is that separates a score of 8/10 from a score of 9/10!) Fast-paced lectures make sure sure the students who start off slowly get little chance to get ahead; the quickest students (who are often, but not always, the brightest) control the pace in these classes.

All of these factors discourage students who are excited or intrigued about math, but who are put off by the way in which it's often taught. We can't afford to turn these students away. The fact of the matter is we, as a society, need more mathematicians than we can possibly prepare, and we do no good in discouraging anyone who's passionate about the field from pursuing it further. We do well to let as many students through the gate as we can, and to give them all of the support and encouragement they need to develop their skills fully. We do well to eliminate curves and to downplay in-class competition between students. We do well to "coarsen" our grading scales to accommodate "big-picture" thinkers who might miss a detail or two but who grasp complex systems in their entirety. We do well to step away from our classroom's center stage and let students take our place, so that it's not to the top ten percent that we teach, but to the class as a whole.

The bad news is that these practices are not universal; the good news is that they are more popular than ever. They're in use throughout my department and many like it. The youngest math teachers (at every level) are more adept at applying them than their older peers. These teachers are daily developing new tricks and techniques to make these practices more effective, and they're not shy about sharing these tricks and techniques with their colleagues and with their students. The future is bright for math education.

Stick with it, Becky! Welcome to the team. You're in good company. You'll do wonderfully.

Be afraid, but don't be afraid of your fear

Today I had a very contemplative morning. I had a good run, and it couldn't have been a nicer day for it: the air has an early-autumn crispness, and the trees a golden-green that connotes an ageless seasonal change.

I gave thought this morning to an opportunity I've recently been granted, one of which I'll soon take advantage, and which I hope will bear fruit. I can't say much of it publicly yet, but I will say that I became fully determined to make a move this morning when I realized two things:

1. I'm a little afraid of taking this chance, and

2. it's that little bit of fear that's convinced me the chance is worth taking.

I know that if things work out the way I hope they will I'll be presented with entirely new challenges I've not yet faced in my career to this point. I'll be doing a lot of learning on the fly and a lot of playing it by ear. I'll be bearing a great deal of responsibility, but also relying to a greater extent than ever before on others to help me carry out the tasks I'll be responsible for. I'll be delegating, relegating, moving and shaking, and working my tail off.

It's a bit frightening. I've almost balked once or twice because I know that though I'm qualified to take this on, and though I'm as ready as I'll ever be (and as ready as anyone could be expected to be), it'll still be a rough road. I'll definitely be outside my comfort zone. It was only just this morning that I admitted to myself that I've been a little afraid of moving down this path much further.

But you know what? That's a good thing. If we don't put ourselves in that "zone of proximal development," as Vygotsky put it, we don't put ourselves in a position to do much learning or growth. If I only ever do things that I know that I can do, that I'm utterly unafraid of doing, I'm not going to get much out of them.

These twin realizations: the presence of fear and the healthfulness, the appropriateness, of that fear, have moved me forward. I feel stronger and more whole.

There's a parallel in one of my courses right now. Yesterday I spent roughly 10 hours grading (9:00 a.m. to 7:00 p.m., almost nonstop), about 7 hours on Precalculus alone. Their most recent homework sets (especially Homework 6) were challenging ones, involving complicated problems which had to be broken down into simpler subproblems. The students had mixed success in seeking solutions to these problems. Some patiently broken them down and crafted careful solutions; others were less successful, impatiently attempting to swallow the problems whole.

The problems are meant to push the students forward, to move them from a place where they feel comfortable to one where they feel challenged, and maybe just a little scared. I'm confident that the students can do what's asked of them, though, and that they have the skills needed to solve the problems I give to them if they take their time and work carefully. I'm confident that if they take time to contemplate the problems piece by piece, they'll grow in confidence and competence.

I sent the students an email just now, including a model solution to the toughest of the homework problems. Here's some of the text from that email; I hope it helps them place our work together in a healthy context:

...I also recognize that the problems I'm asking you to complete are not easy ones. Each of those on HW 6 likely took you 45 minutes apiece (maybe more) if you did them clearly, capably, carefully, and well, as many of you did. I was impressed with the neatness and precision of some of your answers!

These are not easy problems; they are challenging and probing. It's for the best: I believe that challenging problems are those most worth doing. They push us to our limits and force us to confront fully our understanding of the ideas we come up with together. I'm just relearning now (relearning from you, as much as from any other source) that those things that are most worth doing are those things that are difficult to do, that challenge us, and that, perhaps, even scare us a little.

My reflective morning's brought me other thoughts as well, about which I'll be posting throughout the week. Several stem from my ongoing reading of Parker J. Palmer's and Arthur Zajonc's The heart of higher education: A call to renewal (transforming the academy through collegial conversations) (San Francisco: Jossey-Bass, 2010), the centerpiece of the Learning Circle I've been taking part in (when possible) this semester. The book has great richness, and has led me to reflect deeply; as I wrote to myself at one point "there's poetry on every page!"

In the next few posts I'll talk about what I've learned from an ongoing project about which here I've yet said little, about resistance to curricular change on the part of even the most well-intentioned (and change-oriented) faculty, and about my own elusive "community of scholars" Palmer and Zajonc extol on page 128 of the book I mentioned above. About all of these I've thought today.

As I said, I had a very contemplative morning.

Math...who needs it?

As a low-stakes exercise at the end of my first section of Precalc this morning I asked students to write down the most math-related activity in which they took part over the weekend. I got several quotidian responses ("I attempted to complete HW #5," "Chemistry HW," and the like) but I got some more exotic ones, too:

"I explained what a TI-83 was to a 6 yr old"

"The most math related thing I did this weekend was weigh the amount of almonds I wanted at Earthfare and calculate the price in my head."

"Calculated my availability for a client given all my meetings and classes that I have this week."

"I worked at the hospital all weekend, and at my job, I utilized math to calculate the number of calories and carbohydrates patients had been consuming."

"Averaging pace/mph/minutes per mile while running 1/2-marathon."

"I got kinda bored, so I figured out every time of the day where the angle of the clock hands were exactly the same as those of 4:00"

Fun times! We'll see what my second section can come up with.

On another topic, this afternoon I'm off to my fourth Carolinas Writing Program Administrators conference at the Wildacres Retreat Center just off the Blue Ridge Parkway. This year's theme is seeking external funding, and participants will spend a bit of time hammering out grant proposals as they bounce ideas off of one another. (Our current Writing Center director and I are planning some sort of regional writing-themed conference that would bring in not only university students and faculty but also K-12 educators and their students, and members of the community at large.) Of course, I'm sure I'll find time to work on my ongoing research with the College of Charleston crew (we're presenting this work at the Four Cs in March), and to cut loose with my comp-rhet buddies from all over the Carolinas.

Further bulletins as events warrant!

UPDATE!

Because I know you've all been on tenterhooks since my last post, here are some of the most interesting weekend uses of math from my second section:

"I built a table and had to measure where to cut. I also wired a dimmer switch which required me to use some math."

"The most mathematical thing that I did this weekend was to figure out how many CDs my band sold based upon how much money we had in our 'money jar' at $15 an album. Also in figuring how much we owe our bass player when paying her 22% revenue earned per gig."

"I was playing a power chord on a mandolin and my friend asked me, how do you do that? I told him it was the same as a power chord on a guitar but reflected over the origin."

"I was actually bitching last thursday about how I would probably never use the research from our homework ever, but this weekend I got into a discussion about Dow Jones & was proven wrong. I laughed and will no longer bitch. :)"

Progress! :)

Into the woods

It wasn't until I wrote yesterday's blog post that I realized the extent to which I'm pushing inquiry-based learning in both courses I'm teaching this term. In both Precalc and Abstract Algebra I, the majority of the homework problems students are being asked to complete are what can legitimately be called research problems, and I'm posing them as such, guiding the students through an initial "data collection" stage, leading them then to a "conjecturing" stage, and from here to a point where they should be ready to offer at least a partial proof. The questions I'm asking are very open-ended, and in a few cases already this semester I'm not even sure I know the answer.

Example: I've got the Abstract students making conjectures about the relative primeness of consecutive terms in generalized Fibonacci sequences: for what natural-number pairs (α,β) is it the case that any two consecutive terms in the sequence defined by s₀ = s₁ = 1, s_n = αs_n-1 + βs_n-2 are relatively prime? I admitted up front that I don't know the answer to this (though I have some guess as to what might be true), but I asked students to try out several cases, formulate a conjecture based on the data they gather, and try to prove their hypothesis.

What fun! I'm having fun, anyway. And what a way to learn! I have no doubt that the students are apt to become more talented mathematicians (and more generally, problem-solvers) when asked questions like this than when asked to complete cut-and-dried textbook proofs for which the answer is already told to them.

How NOT to graph a shifted function; or, The nature of mathematical research

It happens to us all at some point: we're confronted with a problem to which we simply don't know the answer. It's a problem never posed to us before, one we've never seen...it may not even look much like anything in our prior experience.

It's happened to me. Many times.

For example, for the past year or so I (and, off and on, several undergraduate researchers and a couple of colleagues) have been struggling to find answer to a seemingly simple question: where on Earth does the mode of the independence polynomial of an arbitrary 2-regular caterpillar lie?

Okay, so maybe it's not that simple of a question...but it's one that's resisted analysis of every kind we've attempted for well over a year.

However, undaunted, we have tried several different means of cracking this muthah. We've tried geometric methods, combinatorial methods, algebraic methods...even analytical methods. We've tried it all, to no ava...well, to some avail: we've learned a lot about the structure of the objects we're studying, and though we don't yet know what method will work to solve the problem, we can tell you several methods that won't work. Hey, we've tried.

And that's what matters: the fact that we've tried. In the end, it's okay to not know what the answer to a particular question is. After all, none of us are born with inherent knowledge of algebra and calculus and combinatorics: we're going to be asked questions the answers to which we simply don't know.

Put another way, ignorance is inevitable; what matters most is how we confront that ignorance. Inaction gets us nowhere. Action of any organized kind is preferable, and more preferable still is action of a sort our experience suggests will give us a means of responding to the problem we're posed. This kind of confrontation with ignorance is called learning...or even research.

Yes, research: it doesn't cheapen that lofty term at all to use it to refer to the simple actions we undertake when we, for example, try to graph a simple function we're unfamiliar with.

Allow me to demonstrate.

When confronted with a truly unfamiliar function, here's what not to do:


You can't be expected to be familiar with every function ever invented...there are too many of them! But don't just sit there! Don't let ignorance get you down! If you're not sure of what to do, maybe try something that's worked in the past, like...


Ah...now we've got some traction...a few more values...


...and we're starting to see results...now let's plot some points...


Huzzah!


Ignorance dispelled! Or at least held at bay for a bit. Congratulations: you've now learned something new. Put another way, you've completed a miniature research project. Seriously, you've just done research, applying known methods to approach an unknown problem. That's how you do it.

At the risk of sounding repetitive, let me exhort you once more: please, don't just sit there. It won't simply "come to you" if you're not doing anything at all, but it might if you try something out.

P.S.: photo credits go to my former student, and awesome stats major, Karl. Thanks, Karl!

Back

We're back. It's been a while.

While the REU seemed to eat up less of my time this summer, revisions on the book (to appear early in 2012 under the title Student writing in the quantitative disciplines: a guide for college faculty) and work on the Curriculum Review Task Force seemed to take up every last bit of whatever was left.

We're now four days into the Fall 2012 semester, and I already feel as though I've found a groove in Precalculus. I've not taught this course for three years, and I must say that I've been looking forward to teaching it again. I've thought a bit about how I would approach the course, I've come up with some new activities (like this one), and I'm coming at it with renewed energy. So far the class has been great. (It doesn't hurt that the department's choice of text is not catastrophically awful, like the text we'd adopted the last time I taught that course.)

We spent today motivating relations and functions, and I ended class with a low-stakes writing exercise (who, me?) asking the students to work in small groups to come up with several examples of relations or functions which have real-world relevance, expressed as "pairings" between sets of numbers. They came up with some fantastic ones, some of which could the basis for interesting statistical surveys. A sampling (all verbatim):

• The decrease of the temperature paired with the increase of the elevation
• The number of texts you send paired with the time spent on your phone
• Pair the childhood obesity with each child's level of poverty
• The profit of the lemonade stand paired with the amount of sugar used
• The speed limit of an area paired with the number of car crashes in the area
• The amount of wildlife disturbances compared to the average of the new developments
• Pair the number of baseball ticket sales with the baseball team's winning record
• Pair the profit made by jacket companies based on temperature

I'm stoked. Both sections of this class seem to be gelling already, and they're full of outgoing individuals. Already obvious "leaders" are emerging from among the ranks of those students who are unafraid to ask questions, suggest answers, and put solutions on the board before the whole class.

Abstract Algebra has yet to get into the same groove, but as yet we've only met twice, and yesterday's class meeting was dedicated to an intentionally chaotic consideration of a boatload of multiplication tables I'd asked them to construct. In asking them to analyze and explain the patterns these tables exhibit, I'm leading them to begin thinking about what salient features the most "well-structured" algebraic objects (sets equipped with a binary operation) might possess. We'll make that more explicit tomorrow when we define monoids, groups, and semigroups.

More to come soon, I promise! On CRTF (oy), on the QEP (oy oy), on many more things...

Fun Times

I'm smack-dab in the middle of the freest time of year for me, that three- our four-week-long end of May, during which time I'm generally "relaxing" after a successful semester, working like mad to take care of the various reports due from me in the next few weeks, and busily prepping for the REU that starts two weeks from tomorrow.

This year my wife and I were able to get away for our first "real vacation" (defined as "a trip involving neither work nor family visits") in several years, a five-day cruise to the Bahamas. Of course, being who I am I managed to make the most of it by bringing along some highly inappropriate pleasure reading, the thirtieth anniversary edition of Paulo Freire's Pedagogy of the oppressed, the central text for the summer Learning Circle I'm taking part in in June and July. (The only reading material I saw which may have vied with it for the "Most Ironical Reading on a Cruise Ship" award was one woman's copy of Orwell's 1984; I think if she'd have been reading Huxley instead, she might have had me beat.)

I'll likely have more to say in the coming weeks about Freire's philosophy as it applies to math education at the university level, but I wanted to put forward in this post an idea for a new ongoing writing project I hope to implement in at least one of the two classes I'm organizing in the fall (Precalculus and Abstract Algrebra I).

Oddly enough, I got the idea from the cruise company. Every evening around dinner time we were treated to a delightful turn-down service, featuring complimentary mints, expertly folded towel animals, viz.:


and a copy of the Fun Times, the cruise ship's guide to all of organized activities that would be going on on the ship the next day. It was little more than a newsletter, three or four pages in length, just the sort of periodical I think a class (or two) full of students, working together, could crank out at least once a week, if properly prepared to do so.

So here's the idea: ask students to put together an ongoing "newsletter" for their class, The Algebra Times, or The Precalc Picayune, if you will. Its content would be flexible, and what went into it from week to week would be left to the discretion of the students (I'd want to have as little to do with its creation as possible). Perhaps, for example, the precalculus newsletter could include

• study tips,
• hints for tricky homework problems,
  
• advertising for study groups,
• applications of course material to areas outside of class,
• games and puzzles,
• "letters to the editor,"
• recommendations for class activities,
• recaps of recent class activities,
  
• personal reflections on math in general,
  
• etc.

Whatever. It'd be up to them. I'd stay out of the day-to-day operations. Maybe I'm being overly sanguine, but I can imagine a handful of particularly eager students taking on editorial and managerial responsibilities (there are a few in every class). To ensure participation by the class as a whole I'd require every student to contribute to the newsletter at least once, twice, thrice, something like that, during the course of the semester. (Jointly-written contributions would count.) It would be difficult to "grade" contributions (I might shy away from this entirely, keeping it a low-stakes exercise), although I'd provide feedback to authors confidentially.

How's this sound? Colleagues: have you tried something like this before? Students: would this be something you'd be all upon?

Whelmed

The end is near. I can almost see the end of the semester from where I stand. And, unlike many of my colleagues, friends, and students, the rest of my semester should be relatively unbusy (compared to the past month or so) after this coming week. I no longer feel overwhelmed; I'm simply...whelmed. However, Webster's Free On-Line Dictionary lists "whelmed" as a synonym for "overwhelmed," so maybe that's not accurate.

The past few weeks I've felt the urge to post here, but have been at a loss for what to post about. Anything that I felt was worth saying was too trivial to mention or to comprehensive to put into a one- or two-page post.

I thought about writing on some of the Neat Teaching Ideas my colleagues offered up in the Project NExT-SE session at the MAA conference in Tuscaloosa this past weekend. My UNCA colleague Kelli talked about the "peer mentoring" program she's been using in her Calc I class here this semester, and my Project NExT colleague Kade talked about using "math moments" to expose lower-level math students to nifty ideas from higher mathematics, like the Four Color Theorem and Russell's Paradox. I've done this sort of thing in the past, but not recently, and I've never tried putting a peer mentoring program into place. I'm going to try both out in Precalc next fall.

I thought about writing on the feeling I had driving back from Alabama, a feeling of calm, serenity, and oneness, as, just for a moment, I felt like I saw with perfect clarity my role as a teacher and learner. I felt for a moment as though I understood precisely how what I do affects what my colleagues do and reciprocally, and precisely how I help my students to learn as they help me to do the same. It was a pleasant moment.

I thought earlier today about writing on a common category error my MATH 280 students tend to make...one which I didn't mention in class this morning as I was debriefing them on their latest homework sets. Namely: students frequently confuse conjunction ("and") of mathematical statements with intersection of sets, and disjunction ("or") of mathematical statements with union of sets. There's little to do but practice in order to overcome this confusion, training oneself through repetition to recognize the different between a set or a class on one hand, and a statement or a mathematical claim on the other.

Snippets, random snippets. If you've got something to say about any of them, feel free to chime in. In fact, feel free to chime in even if all you have to say is utterly non sequitur; I always love hearing from my readers, and I want to know where you are right now: puzzled and perplexed? Curious and questioning? Or simply stressed, and tired, oh so tired?

Hang in there, my friends. The end is near. Have a seat beside me and tell me a simple tale; I'd love to hear it.
