In about a week I will be presenting twice at the AMATYC national conference.  The first presentation is an IGNITE talk.  Basically 20 powerpoint slides that auto advance every 15 seconds; start talking!  I am one of about 22 of us, and I will be talking about using what I call Competency Clusters.  Basically the idea is to group your homework problem assignments into small clusters that are related to help students understand the differences and similarities between the problems.

For example, x^2 - 1 = 0 , 1 - x^2 = 0 and x^2 + 1 = 0 all look similar, but only two have solutions over the real numbers.

A copy of the slideshow I used will be posted next week after the conference.  I will also post a link to the video of all of the talks when it is up.  I would also post copies of the slides, but I have a lot of animation on each slide so it becomes a jumbled mess.  A link to the video of the entire show will be posted about 10 days after the conference so you can see all of the talks.  Below are the resources I mentioned in the talk.  Thanks as always.

Statistics simulations with data pulled from a web page!

This is the post that goes with my presentation Sunday at the  Joint Mathematics Meetings

The other talk I was doing was over simulations for statistics classes.  I discussed the idea of using a data set the students suggested by pulling a data set from a web page and then having the students do various things with the data in the web page.

copies of the slides are here

Group Tests for Joint Mathematics Meetings

I am doing two presentations at the Joint Mathematics Meetings this January in San Antonio.  One is on group tests.  The talk is scheduled for Monday January 12th at 10:15 - 12:15 in room 212A of the conference center.  Copies of my slides and the handouts, along with another handout with more examples are below.
