The Mathematics of Weight Loss

The picture below was taken in college when I was around my heaviest weight ever of 314 lbs.  I've always been a big person and I there is a lot that goes into why this is the case as well.  Was it the way I was raised?  Was it genetics?  Was it just me eating myself into a hole?  Well, this is not the place where I'm going to talk about that. What I will say, though, is that this is the most recent picture of me a little over 70 lbs lighter than I was at my highest weight.  This is a blog post about math, so I'll let you figure out my approximate current weight on your own. With all of that out of the way, I'll tell you what this blog post is really about.  I don't really like talking about myself because I'm generally a very self-conscious person.  But this weekend I was thinking about what I might...

My Experience at the Charles H. Wright Museum of African American History

Note:  This was a trip that I field trip that I took my Math For Education students on during the Winter 2012 semester.  The original reason for the visit is that we were promised that there would be a display about African American Mathematicians at the museum.  However, that display was not there.  My students were asked to leave the group, just as I was. On Saturday, March 24, 2012, I attended the Charles H. Wright Museum of African American History.  I didn’t know what to expect before I attended the museum.  The only African American History that I can ever remember learning about is through textbooks, television, the Internet, and through African American History Month activities that were done in school.  I had ever been fully immersed in an entire exhibit solely dedicated to African American History.  I didn’t know if I would agree or disagree with the viewpoint of what was presented in the exhibit,...

Jing and Geogebra

During the Summer 2012 semester, I decided to have my Math for Education students use Jing to send me a diagram of something that they were supposed to do using Geogebra.  If you aren’t familiar with Jing, it is a free screen-capturing and screen-casting tool from the people at Techsmith, located in Okemos, MI.  And if you aren’t familiar with Geogebra, simply put, it is a free alternative to Geometer’s Sketchpad, but it can do lots more. First off all, I have to say that I had always wanted to use Jing and screen-capturing with my students, but I wasn’t sure from what angle I wanted to approach it.  Many instructors have students create their own screencasts (a fairly well-known example is Mathtrain.tv).  Of course, I already use screen-casting on the instructor end by creating screencasts for my students on topics they are struggling with or by providing video feedback on student assignments.  I just hadn’t ever...

Learning from Ignite

If you don’t know what Ignite is, simply put, it is a format in which speakers are limited to using 20 slides and each of those slides automatically advances every 15 seconds.  Thus, a speaker must get their point across within a maximum of 5 minutes. I learned about the Ignite format from past conferences that I have attended.  And I have attended several Ignite Events in the Detroit, MI area (they have them all around the country). This semester, I decided to have my Math for Education students give an Ignite-style talk on the last day of class.  They had two major content goals – they were supposed to summarize what they learned during the semester and they were required to have at least 5 slides on a topic that I pre-assigned to them (e.g., hexagons, pentagons, etc.).  The other catch is that they only had 30 minutes to prepare their slides and presentation. I learned quite a...
