Earlier that summer, he had been reading about a new trend: coursecasting, or distributing class lectures as podcasts. So he bought his own $39 microphone, and gave the idea a shot.
To present a highly visual subject like biochemistry, Gallivan now relies on enhanced podcasting to include images like chalkboard drawings and website links to protein databanks, for example. Among his 200+ classmates, two-thirds of students regularly listen to podcasts of his lectures. They have also been downloaded more than 700 times per lecture, by biochemistry enthusiasts everywhere from Mexico and Norway to Australia ...
