One Proportion Tests w/ Binomial P-Values

One Proportion Tests w/ Binomial P-Values

Last fall I began using an approach to incorporate inferential techniques into my Intro Stats course much earlier than I used to. (Hat tip to Matt Davis from Chabot College in CA for the inspiration to do this.) I began using simulations, randomization, and bootstrapping to start exploring statistical inference. I introduced my students to the concept of confidence intervals and evaluating claims about population parameters based on sample evidence. I first formalize the hypothesis testing language and procedure with…

Last Spring I flipped my elementary algebra class. For each section I used a cycle of three assignments in MyMathLab to make it all work. FLIP Assignment This was a media assignment that incorporated concept videos, example videos, and homework exercises. Students completed these assignments before class. Reflect Quiz This was a 5-question quiz, focused on the problem types I felt were the most important in that section. The first attempt loaded a personalized homework, and students could take the…

Wildcard Wednesday: Winning Students Over With Technology

Today I led a highly structured class that made effective use of technology, and finally got some skeptical students on board. Several students told me when they got to class that they were having a hard time with rationalizing denominators, and fortunately I had my lesson set up to begin there. We started by rationalizing a one-term denominator and then a two-term denominator by hand. I explained how and why we began rationalizing denominators in the first place, and although…

Last week I came across a Wired article: Wolfram|Alpha (& AI) Is Making It Easier To Cheat, and reading the article brought so many thoughts to mind about teaching mathematics in today’s world. Here goes … 1) We need to make sure that students understand that HW is a learning tool, not just something that earns points. — George Woodbury (@georgewoodbury) August 25, 2017 I feel that we often assume that students know why they do homework and that they…

I tried something new in my intermediate algebra class. Over the last 3 classes we covered absolute value equations, absolute value inequalities, and graphing absolute value functions. I tried to tie these ideas together through the magic of Desmos, and although it started strong, it could have ended better. We began with the equation . Students solved this by hand and we went over the solution. Then I had students use Desmos to graph and determine where it intersected the…

Wildcard Wednesday – Sending the Right Messages

Wildcard Wednesday – Sending the Right Messages

Comments 0 Comment

In all of my classes I have been focusing on sending the right messages to my students. I have become more aware of the importance of this through Jo Boaler (Mathematical Mindsets) and Carol Dweck (Mindsets). Here are the messages I have been stressing. Speed is not important. Math takes time, and you want to work at a pace that leads to your understanding. Praise effort, not ability. For example, I told my statistics class how proud I was of how…
