Math-a-blogging

So, I sort of lied. I have been blogging in another life. As part of a Math course I recently developed, I set up my own blog to explore many of the concepts in the Algebra course. It’s called Maththinker. Initially I set up the blog as an example for students of my course. Many of the course activities are designed around the blog as the goal is to teach teachers the importance of getting students to express their mathematical thinking in writing. Writing out the thought process of math helps reinforce the learning and also helps students develop a solid understanding of what they are learning. Blogs naturally present a great tool for achieving this.

In addition to the blogs, the course will help students practice developing their own electronic visuals for teaching using simple graphics in PowerPoint. I truly believe that developing visuals or even drawing out concepts helps reinforce learning just as writing does. Even though the students of this course are producing something that they can use in their classrooms, they are also using that visual-spatial muscle to think out problems and concepts. The illustrations also allow the students to enhance their reflections and descriptions of concepts in their blogs.

In addition, to encouraging math writing, the course also focusing on helping teachers develop their own ‘real life’ applications and examples of math concepts and stories. Students share their examples including their own illustrations or diagrams in their blogs. They are encouraged to respond and provide feedback on each other’s work in the blog comments.

Here’s a screenshot from a quick slide show I developed that demonstrated the effect of changing variables in a quadratic equation. I used an applet available in the National Library of Virtual Manipulatives to create the graphs quickly and painlessly.

Working on this course also gave me the opportunity to re-learn some of my ‘rusty’ math. Imagine, I now remember what to do with a quadratic equation. In general, I feel like I’ve developed a greater appreciation of math and it’s applications.
