Becoming more Human

Wednesday I gave a test in Calculus. It was covering limits at a point, at infinity, one-sided limits, continuity, etc., even some free fall questions leading into our next unit on differentiation. The day before the test, I was nervous that the test was not going to go well. Review, things that should have been easy, was like pulling teeth. I was starting to doubt myself and my teaching.

During the test, I was looking through some stuff in my classroom and I happened upon my limits test from when I was in high school. I got a B+, and there was a calculator and no-calculator portion. I instantly thought, "Arg! I should've made a no-calculator portion!" Instead of dwelling on that, though, I just looked it over and found my mistakes...very interesting ones. Since the class finished the test with time to spare, I decided to show my test, and look at my mistakes. Looking at the problems I answered incorrectly, I asked the student to decide where I went wrong and what the answer should be.  We went through the whole test like this, and even on some of the questions I answered correctly, I asked why that is the right answer.

This little exercise was a time-filler, yes. I think it made my student view me as a co-learner and as someone who has gone through what he is going through. I'm not just a teacher, I'm a student and learner too. I make mistakes in the classroom all the time, so it's not that my students view me as perfect and error free, but I think showing my old test and what was expected made a stronger bond between us. While I don't have all of my tests from calc, so I won't be able to do this frequently, I do plan to share from my experiences in calc during high school, and I hope to bring in some of the activities that we used (and some others!)

Confession...I'm planning to use Khan Academy this year

It seems Khan Academy (henceforth referenced as KA) has a pretty bad rap in some math teacher circles.  I understand that the videos are somewhat lacking in the engagement factor, and motivating students with points and badges can seem somewhat elementary.  I also see that KA tends to focus more on a procedure/pattern than actual problem solving. 

All that said, I will be using KA this year in my resource classroom.  I have a group of students that are in my class for numeracy skill building/strategies instruction.  I'm supposed to be teaching them 25 mins/day and allowing them 25 mins/day to work on their homework or classwork.  I have students of all grade and ability levels in one resource class, so lesson planning becomes difficult.  Twenty-five minutes is not a long time when you think about it, seemingly less when you think about real problem solving tasks.

Enter KA.  Each student can be working on exercises related to what their individual math course is or will be addressi…

ASL/English Vocabulary in the Math Classroom

My last semester in college, while I was student teaching, I had a class that emphasized different key topics in the field of Deaf Education.  One such topic was vocabulary development.  We all already knew that students who are deaf/hard of hearing have a lower vocabulary than their same-age hearing peers for a variety of reasons not least of which being their limited access to "incidental learning" that comes from listening to other people's conversations/tv/radio, etc.  In our class, we talked about ways to introduce new vocabulary in order to give students a more connected understanding of the new word in its five distinct forms.

The Birth of an Assessment

Sam recently blogged looking for feedback on an Algebra 2 assessment he gave, but mainly to start a conversation about assessment creation, etc.  My classroom assessments have changed drastically in my short 2 years of experience.

Here's a chronology of my growth:

1st year teaching (Algebra 1 - full year course)
Classroom instruction followed the sequence (and pacing to some extent) of the textbook we were using (McDougall Littel Algebra 1).Assessments were largely based on Chapter Tests from the end of whatever chapter we were in, re-typed/formatted but using the same problems with little thought to balance what was actually being tested.Points were assigned to each problem to award partial credit for being on the right track (this often ended up meaning the more difficult problems were worth more points than the basic problems - more steps = more points)Here's an example of one such test: Chapter 9 Test.  Point distribution is as follows (side note: what was I thinking with th…
