I've done something similar for Animal Behavior. I ask them then to write a description of what they've seen without the benefit of David Attenborough's wonderful intonations. It's fascinating how the perception of the images differs when the students are being TOLD what's happening and why it's interesting, as opposed to having to decipher it themselves. I recall this procedure being especially effective with a segment showing chimpanzees chasing, trapping, and killing colobus monkeys for food. Few of the students realized the degree to which the chimps were displaying coordinated hunting behavior when that aspect was not pointed out to them.
Most people are still in the passive TV watching mode.
Of course, you will need to purchase a cable that will connect the computer to the laserdisc player. This is certainly a helpful addition I've not seen on laserdiscs. This is just a little story that has to do with using videos in the classroom. Two years ago I was at a conference concerning technology in the classroom. One of the presenters was an astronomy instructor.
