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.
Many laserdiscs contain many series of visual frames and short video clips and animations with specific science content. This can be easily done with existing software or by creating your own hypercard stack which interfaces with specific frames of a laserdisc. Examples for existing interface software can be purchased for the Bio Sci II laserdisc and the Visual Alamnac.
