Lost Pointer in Tablet Projection?

Many of us in math (and many other technical subjects) are now using tablets (slate tablets, tablet PCs, or peripheral tablets) to teach classes. Using a tablet to project what you’re writing has several advantages over traditional whiteboards/blackboards: 1. You can face the students (instead of facing the board). 2. You can make better use of color, shading, and drawing tools (see How Tablets Enhance the Math). 3. You can save your lessons in as either images or screencaptures (videos of the computer screen with your audio recorded in sync). There is, however, one problem. When you project the image of your journaling software onto the “big screen” in your room, the pen tip is typically projected as a black pixel. This is not so much of a problem when you’re actually writing, but is a big problem when you’re using the cursor to point at some part of the screen (nobody in the classroom can see where you’re pointing). Luckily, there’s a simple solution. Kenrick Mock (@macharoni on twitter), from the University of Alaska Anchorage, a computer programmer and tablet PC enthusiast has written two programs that simply create a colored circle of emphasis around the cursor area. The pen tip becomes easily visible. I’ve written Kenrick’s free PenAttention program before, but it was worth mentioning again for two reasons. First, Kenrick has just written an update for...

Top 10 Technology Tools for Math 2008

1. Jing gives students and instructors the ability to capture an image of any graph or equation they see on their screen and share it anywhere else (message boards, emails, papers, digital assignments). Using Jing you can also record videos of up to 5 minutes in length. [Free, Mac/PC] Not sure how to use Jing? Check out the tutorials at the end of this post. 2. Wolfram Demonstrations provides close to 3,000 interactive demonstrations on mathematics. Students and instructors can play with demonstrations by downloading Mathematica Player. Demonstrations can be written by anyone with a copy of Mathematica and are reviewed before they become part of the Demonstrations Project. [Free, Mac/PC] 3. WebAssign is a publisher-independent site for online homework. It was designed originally for physics and does a particularly good job of handling the problems unique to learning math-based content. Publishers work with WebAssign to create online homework for their texts. [$ for students, PC/Mac] Note: You can write your own problems for WebAssign, in which case, there would be no cost for students. WeBWorK is also worth a mention here for the more technically-inclined. 4. WizIQ provides a platform to easily hold online office hours. You have the option of audio and video on both ends, multiple users, interactive whiteboard, and file upload. Sessions are recorded and can be accessed for 30 days. [Free, Mac/PC] 5. Windows...
