I have viewed laser discs on physical science and they too are very dry. I personally think that when the laser disk is a presentation of facts then the disk is a waste of money. Now, when the laser disk is interesting and requires thinking on the part of the student then I am for the disk. The laser disk on oceanography is good because we have to think and the student is engaged.
Laser disks are very good for biology when the teacher has no models in the classroom.
