Google Search Returns Interactive Function Graphs

What a great new feature that has just been rolled out by Google. Now when you search for a function - like sin(x) - the first result is an interactive graph right on the search results page. Very, very nice. Here is an example:

The Post AP Delima

When teaching AP classes, there is the question about what to do with the time after the AP exam. I love the projects we do in my computer science classes, but I have tried various things (with various success) in my calculus classes. This year the students worked on making fun resources for other math teachers. Here is an intro video they produced promoting being able to calculate percentages in your head.



This video and other supporting resources can be found here, along with a comic that explains to students one method for doing such calculations in their heads.

While the project went well, I am still searching for what could be the best use of the post-AP time in the calculus classroom.

Why Calculus?

The sequel to the "Why Math?" video is now ready!

Why Calculus?



The next video in the series that is in production is "A Problem with Math Education."

Why Math?

A few weeks ago I listened to Conrad Wolfram's TED talk and I started jumping around the room when I got to the 4:00 minute mark. His slide with four points on it matched beautifully the discussion I have each year with my students about why we do math. Inspired and validated by his remarks, I produced this video capturing the essence of the conversation I have with my students about, "Why Math?"



Now it may seem like a video about "Why Math?" does not fit well with a new blog about technology transforming pedagogical practice, but hold on. After the next video (Why Calculus?) I will explore what I see as a problem with math education and the role of technology in the solution.

Until then, whether you have taught or been taught in a math classroom, let me know how you would answer the question, "Why Math?"
