Steady as She Goes

Earlier this week I was pretty much over my head.

We moved into an area that has to do with manipulating functions in terms of each other – adding, subtracting, multiplying and then dividing functions by functions.  And on top of that, we started solving functions “in terms of” other functions.

 I didn’t know what that stuff meant either only five days ago.

 I struggled with the textbook and just couldn’t get past the language. I’d start reading and simply get lost. I’d see the words and numbers but they just didn’t make sense.

All of which got me thinking about my own approach to teaching. 

I try to get my students to “jump in now” and start doing journalism, especially multimedia journalism. I (along with millions of 20 and unders and not a lot of over 40s) am convinced that you can’t learn Photoshop or Final Cut Pro or any complicated piece of software by watching some expert demonstrate tools on a video projector and lecture about techniques. You gotta do it with your own hands and fingers and make mistakes and try again until it gets into your muscles.

Seth tells me that’s how it works in sports. Reading might be good for motivation, but a chapter in a book is probably not going to help you two-putt as much as getting on the green for 200 strokes a day.

I think the same is true for math. Watching even a very good teacher such as Steve takes you only so far (not very). It takes reps for the ideas to begin to sink in.

I didn’t used to believe that.

Back when I cared about playing music, especially recorder or clarinet, rather than practice, I’d read books. I read about the clarinete’s history and construction. I became an expert on the different woods that a craftsman could make a recorder out of. I knew the attributes of rosewood, ebony, and boxwood. I took a course about music theory at the University of Arizona and got an “A” (one of my few).  But I never got very good at either clarinet or recorder.  When I should have been practicing an A minor scale or learning how to improvise by memorizing chord progressions, I was reading an article or listening to a lecture.

Photography was different. I got out in the field and took pictures. Thousands and thousands of them. And, amazingly, I got better and better. Portraits, landscapes, sunsets, still lifes.  I used all kinds of formats. Large format, 2 ¼, 35mm, minox, and digital. Now I give lectures about photography to people who ought to be out shooting instead of sitting in a fancy meeting room listening to me talk about taking pictures.

Which brings me back to math.

I was saved once again by the  online math program from last semester’s course through Pima Community College, mathxl.com. 

The access to the program that came with last semester’s book gave me a full year's access to all the textbooks the site serves and its supporting online exercises, videos and animations. 

I found an equivalent level textbook, signed on to it, and started doing my “reps.”

At first I let the program walk me through solving the problems, then I was able to do more on my own. In not too much time I was actually beginning to “get it” enough to be able to tackle this week’s homework assignments. Even the book began to get a little bit more comprehensible. For the first time in at least a couple of weeks, I’m feeling somewhat encouraged.

It felt good to look at the homework assignments in the book and reflect back only a week to where I didn’t know even how to begin to approach solving a single one. Now I’ve done them all, mostly correctly, and sorta get what’s going on.

The skills might not stick, but that’s a story for another time.

Hint Hint

I got a kick out of this email that Stphen Reyes sent to my Math 112 class today:

Class,
This is just a reminder that the last day to drop a course without record of enrollment is today (Tues Feb 10). You can drop via WebReg. Some of you *may* want to consider this option especially with the first test now behind us.

Also, I will be in my office today from 1:30pm to 3pm for those wanting to discuss this. I have the last two homeworks graded if you'd like to pick those up and could also show your grade in the course thus far. I will be distributing print-outs of grades on Wednesday if you'd rather wait.

-----------
Okey Dokey. I'm still in. And in good part, thanks to Seth, I think I'm getting the next section about how graphs of functions move up or down or left or right or compress up or down or left or right.

I'm interested to see how many of my classmates took Steve up on his "suggestion."

Barely

I passed the first test, barely.

My deal with myself was that if I got an F I would drop. If I got a C I would stay. If I got a D, I'd need to decide.

Poor Steve Reyes the teacher didn't look good when class began today. He hadn't shaved and his eyes looked glassy. He started class by telling us what a terrible weekend he had between having a bad cold and spending the whole weekend grading bad homework and even worse tests. He spent the next fifteen minutes discussing how he didn't understand how poorly so many of us had done. As I glanced around at other students' tests I saw scores ranging from the mid 80s to the low 20s. The girl who sits next to me who hopes to be a physiologist got in the mid 70s.

I got a 62, two points above failing.

I was surprised that I wasn't even tempted to quit.

Now I have a chance to once again be my class's most improved player.

But what I found even more encouraging was that I actually understood how I messed up and basically understood everything on the test, even thought my score didn't show that. Also, Steve took off points for some petty "Mickey Mouse" things. I figured out one answer and wrote $4100. The answer for full credit was "$4100 in taxes." What the heck?

I got no credit at all for that problem about the rectangle and the wall and the fence that I mentioned in the last blog. Zero. But I worked through it on my own at home. I brought it to class and Steve said I did it exactly right. He also asked why I didn't do it that way on the test. OK, so now I feel better about that even thouth on the test I clicked that 240 was peremiter rather than area.

Tonight Seth showed me a bunch of good things to know about how to manipulate graphs. I think I have a head start on that and am ready to tackle the next homework assignments.

Students tell me that Math 112 has the highest flunk rate of any course at the University of Arizona. I haven't checked that out but wonder if it's true. I also wonder whether students will drop after seeing their test results today.

I'm still in.

Useful Lecture from a Former Student

Dave Robbins could have put this in comments. Maybe he didn't want you to see his note, but I do.



By the way, he has a terrific blog called "Talking to Strangers." Worth checking out and reading.



Here's what Dave taught his former professor today:



Jay,I just read your latest blog post.



I wanted to comment on the line, "I'm not experiencing a sense of wonder that I could share. I'm experiencing a sense of plodding that I don't imagine a lot of people want to read about."



You're right. No one wants to read about plodding. That's why plodding,suffering and struggle NEVER appear in art. It is the reason why Blues music was never invented, and Shakespeare's Sonnet #30 was never written.



Wait... what? That doesn't make any sense.



What good would a book about learning be if the protagonist never once wanted to quit? Where would be the dramatic ark? Why would the climax be satisfying if it took no effort to get there?



You find me a book where the main character never once suffers - and I'll find you a book that never got published.



What's inspiring about your blog is that it's about a distinguished academic struggling with the same things us lowly undergrads have to struggle with. I don't know how many of your classmates are reading - but how much of a relief do you think that would be to them if they read it and though "Oh... well if he's struggling - I guess I'm not the only one.



"Hang in there, and keep writing about it. It's not suppose to be easy - that's why it's worth reading.

About Friday's math test. I'm pretty sure I passed. Barely.

I messed up the final question. It went sort of like this:

A rectangle has an area of 240 square yards. You need to build a wall around it and a fence across the length in the middle. The wall costs $5 a yard and the fence costs $8 a yard. Find a function in terms of the length of the fence determine the dimensions that will cost the least.

I got started by confusing the area with the perimeter and it went down hill from there.

I worked on the problem tonight and think I solved it. I'll ask tomorrow before I find out my score for the test.

On the Edge

It's been awhile since I've posted. This math thing has really slowed down. Some stuff just isn't clicking.

Our first test is tomorrow morning. If I get a C or better I'm staying for sure. If I get an F, I'll probably drop and try again later. If I get a D, I don't know.

---------------

Good things

1. Steve Reyes is a really good teacher. I am impressed at how much he seems to care about doing well, his grasp of the material, and ability to walk a classroom full of math aptitude deprived 18-yea- olds and me through some very complex ideas. Complex to us at least.

I'm also impressed with Steve as a person. He's 28 and is teaching at the UA with only a bachelor's degree. I don't know whether it is in math, math/education, or what, but that's as far as he's gone so far. Steve graduated from Cholla High School in Tucson as valedictorian and is the first member of his family to graduate from college.

Because he is the exact kind of person I was interested in when I wrote my book, I thought he might like to read it, so I gave him a copy. I hope he has a chance to look at it.

2. I now know how to do things in algebra and with functions that I couldn't imagine knowing how to do less than six months ago. In fact, I can do things that I didn't even know existed less than half a year ago. That feels good.

Bad things

1. I'm spending way too much time studying for the amount it seems that I am learning. Seth assures me that no one in my class is putting in as much time and he may be right. So, I don't know whether it's because it's getting harder or what, but I'm thinking that I ought to be spending less time staring at equations and functions in a book or on a comoputer screen and more time working on my classes that I teach and on photography and my own writing and on my bicycle training for the Bicycle Tour of Colorado and RAGBRAI.

2. I'm not seeing a book or even a good article in this pursuit right now. I'm not experiencing a sense of wonder that I could share. I'm experiencing a sense of plodding that I don't imagine a lot of people want to read about. My best case outcome or climax would be passing a course in calculus at the UA or Pima College some day. That is a feat that probably hundreds of thousands of high school juniors and seniors accomplish every year. It's possible the "wonder" and "insights" come later, once I've learned the language. I'm still holding out hope.

3. I am surprised that the textbook and the online support offered by Pima College is far superior to that offered by the UA. As good as Steve is as a teacher, I'm thinking that I should have enrolled in the equivalent College Algebra course at Pima College. Because of the book's online tutorials and exercises, tt's better, at least for me.

-----------------------------------------

I'll report back on my test.
