Abstract: In the education world we are still using the web mainly as a one way communication tool, simply making it a bit more convenient for students in a conventional course to receive the same or similar material which previously was handed out in class. But the Internet can be used as a two way communication tool where students are actively engaged in manipulating course material, controlling both simulations and live experiments, collaborating with other students and interacting with the instructor. Many of these activities can be done in a laboratory setting as an integral part of a regularly scheduled course, performed asynchronously as homework assignments or completed as a component of a new hybrid kind of distance learning course. This talk will explore some of these options, most of which we have tried at IUS in one form or the other.
