Contemporary Algebra Collection (new resources 2/4/2019)

The Contemporary Algebra Collection now contains 28 activities spread from basic math to exponential functions. All of these activities are based on contemporary examples from the world (e.g. Snapchat, Facebook, Amazon, Spotify, tourism, apps, etc). All the activity links now point to Google Docs that will maintain their “freshness” over time. Whenever I update an activity, the published version will also automatically update at the same link. By publishing the activities as Google Docs, I hope this makes them easier for you to modify activities if you want a slightly different wording or conceptual focus. The collection has also...

Using Math to Understand the Future

Futurist Peter Bishop was one of the keynote presenters at MichMATYC 2010 this year.  He spoke to us about what a futurist does, and shifted our paradigms about how to look at data trends to one that is more mindful of the cone of plausibility.  Don’t know what that is? Well, watch the talk!  If you don’t have a lot of time, then watch the last 20 minutes.  You can also get the slides here. If you’re interested in the other sessions at MichMATYC 2010, many of the slide decks are posted in the Resources Tab of the MichMATYC...

Shifting Assessment in a World with WolframAlpha

I let my students use Wolfram Alpha when they are in class and when they are doing their homework (um, how would I stop them?).  Because of this, I’ve had to shift how I assess on more formal assignments.  For the record, it’s the same adjustment you might make if you were using ANY kind of Computer Algebra System (CAS). The simplest shift is to stop asking for the answers to problems, and just give the students the answers.  After all, they live in a world where they CAN easily get the answers, so why pretend that it’s the...
