In the brave new world of teaching with the World Wide Web, it's all about connections.
Teachers connect with their course material.
Teachers connect with students. Tarrant's website draws on the Web's ability to transmit images and sound as well as text. Students can view a slide shown during his lecture while hearing the excerpt of his lecture that discusses that particular image. Listening to course material is exactly what one student needs in order to study well. Hearing the audio of Professor Tarrant's voice helps a lot.
