podcast and traditional teaching

Sometimes a new medium has unexpected sides. In Belgium a teacher in mathematics and media technology uses unpolite and heavy language during teaching.
One of his students recorded a lesson and put in on a podcast site. Later he edited the lesson and made a technobeat mix out of it. The MP3 is on his way to the top of the hitparade.
Teachers beware of this new medium. One day your lessons are available all over the country in an unexpected way....
