SMART Tablet

During my lectures, I write on the screen of a tablet PC with a digital pen and the writing instantly appears on the screen for the students to see.

I use SMART Tablet. This is a fairly large tablet connected to a Windows PC. Not like iPad at all.

In any way it's better than either chalkboard:

• handwriting is in bright blue, with other colors used for emphasis;
• I have a lot of colorful illustrations, copied as many times as necessary;
• I can insert images, run programs (Excel), go to the internet;
• I don’t have to deal with chalk on my shoes, pants, and lungs.

or PowerPoint:

• No need to prepare the slides (illustrations and formulas!);
• I can change the lecture plan at any time.

I found SMART Tablet quite reliable.

The software I use is Windows Journal.

In the end of the lecture, the file is immediately published in the pdf format to the class web page (as an example see Differential Equations -- Fall 2011).

Whenever possible, I edit the lectures to make them more readable. I use another tablet, HP Slate, for that. Later the lectures are transcribed into articles that you see on this site.
