Murderous Math Tricks

I found this one while wandering about on YouTube.  The last “trick” would be a fantastic puzzle for a Trigonometry course.

Funky function notation

At the UMD faculty workshop, one of the participants had an idea for using an Animoto video.  She suggested it might be a good way to break up a long lecture time.  This got me thinking about short lessons (like the CommonCraft videos).  Just because the video is short, it doesn’t mean it’s not effective. I thought I would try out a short video of my own using Animoto.  This one is called “What is function notation?”  If the video doesn’t load for you, go directly to the site here or see the YouTube rendition here.  Either video can be embedded if you’d like to use them in a course shell. You might be interested in the process I used to build this.  For Animoto, you need a file folder with image files.  First, I created a deck of 75 PowerPoint slides (those being relatively easy to edit).  Then I printed from PowerPoint to SnagIt (because of a special SnagIt save option). Then I saved the SnagIt file as jpg files, where each slide is saved as an individual image file. This gave me a folder of all the slides, but with each slide saved as an image. I then uploaded the 75 images into Animoto and made sure they were in the proper order (for some reason the last slide fell first and had to be moved back...

Common Craft Explains Finance

CommonCraft has three new videos about math (well, technically financial math). I wonder if they’ll tackle the Gaussian Copula Function next?

Teaching Math with Clickers

Today’s guest blogger is Derek Bruff, Assistant Director for the Center for Teaching at Vanderbilt University. Derek writes a blog you may have stumbled across called Teaching with Classroom Response Systems. Here’s a question I ask the students in my probability and statistics course: Your sister-in-law calls to say that she’s having twins. Which of the following is more likely? (Assume that she’s not having identical twins.) A. Twin boysB. Twin girlsC. One boy and one girlD. All are equally likely Since I ask this question using a classroom response system, each of my students is able to submit his or her response to the question using a handheld device called a clicker. The clickers beam the students’ responses via radio frequencies to a receiver attached to my classroom computer. Software on the computer generates a histogram that shows the distribution of student responses. I first ask my students to respond to the question individually, without discussing it. Usually, the histogram shows me that most of the students answered incorrectly, which tells me that the question is one worth asking. I then ask my students to discuss the question in pairs or small groups, then submit their (possibly different) answers again using their clickers. This generates a buzz in the classroom as students discuss and debate the answer choices with their peers. After the second “vote,” the histogram usually...
