University professors have been providing online versions of their class lectures since a long time. Teachers just upload their lectures on the university website that students can download and listen on their MP3 players whenever they like.
But Dr Bill Ashraf of Bradford University has gone a step further. He has abolished traditional lectures in favour of podcasts.
Instead, he's only recording the lessons for students to download as podcasts or video. Students can then ask questions via email or text message, and the professor will respond on his blog.
Dr Bill also has a web-based schedule for students to see when he's free to meet.
