"LectureTools is a student response system that also allows students to take notes linked with the slides and videos presented in class, answer instructor generated questions and pose questions to the instructor. All notes, questions and activities are instantly synchronized with the LectureTools web application."
"New psychological research suggests that university students who download a podcast lecture achieve substantially higher exam results than those who attend the lecture in person." Would have been nice to cite this morning ;-)
App available for iPod touch or iPhone to enable student responses - is free application but with subscription required and the teacher has to download and install some software on the podium workstation to use it
