The basic calculus course at the University of Helsinki has been offered online for many years. The course was completely revised this time. We are trying to activate students by asking them to contribute to weekly forum discussions, and by giving generous extra credit for that. Next time I may make that a compulsory part of the course.

In my last blog I promised to report today about the results of me trying to create podcasts of my calculus lectures. Today I have used my new Mac for that purpose with some success. The ProfCast (http://www.profcast.com/public/index.php) software makes it very easy to create a podcast out of a PowerPoint presentation. It worked for me without problems. ProfCast does not, however, seem to offer any possibilities to edit the audio track. Convenient and easy editing of audio tracks is a strong point of Captivate. ProfCast lacks here.
