## Wolfram|Alpha widgets for an online course

I’ve blogged about using Wolfram|Alpha (W|A) widgets for general use. Since I teach an online intro stats course every year, I thought it be handy to embed the widgets right in the topics section within the course management system. W|A widgets can fetch some data distributions – it’s a lot easier to insert these types things at point of use… Read more →

## Online LaTeX Editors

Although my primary word processor is MS Word 2007 for class materials, I use LaTeX for assignments in my upper level courses. Many of the assignments I create are not too lengthy and so I started searching for a quick browser-based online LaTeX compiler. Here are three I am experimenting with. The first one is totally free. The other two… Read more →

## Elearning on a shoestring

Once again, I’m teaching an online statistics class this Fall. While the online materials that come with the text are really superior, I still needed a platform for my virtual lectures every week.

In the past, I have not required my students to typeset math in their homework. They had the option of using Equation Editor or doing it by hand within their word processed documents. I have also encouraged them to use Google Docs, which has a TeX-like interface for math equations. I recently started using the MS Word 2007 equation editor,… Read more →

Just finished teaching a short course on software for use in math classes.It’s a course required for math majors, and the objective is to familiarize students with the various types of software to do math. Way back when, like ten years ago, math software was the domain of licensed software housed in college computer labs. The usual stuff happened –… Read more →

## Proofs and Wolfram Alpha

In my Introduction to Proofs course, I discussed the proof the following: The cube of an integer is of the form 9k, 9k+1, or 9k+8, for some integer k. The problem is from the text I use, How to Think Like a Mathematician: A Companion to Undergraduate Mathematics The big idea here is to to note that any integer can… Read more →

## Teaching teachers to teach

An article in last Sunday’s New York Times discusses the complex issue of teacher preparation. The writer of the article includes a lengthy discussion of math teaching in particular. I found it to be quite interesting – the work of math educators doesn’t usually make it to mainstream media. Hopefully the Times will continue its coverage of key education issues… Read more →
