A series of video programmes each of which is accompanied by a set of teacher's notes has been prepared by The Television Centre of the University of Portsmouth as an aid to the teaching of ‘A’ level biology. The programmes examine the fundamental anatomy of the dogfish, frog, pigeon and rat and make use of high quality photographs, graphic overlays and 3-dimensional computer animations and diagrams. The material is clear and well presented and has an obvious use in biological courses. Whether the videos should replace entirely the use of fresh material or act as complementary teaching aids must remain the decision of the course supervisors and teachers. The series has been produced with support from the European Commission and has been endorsed by the Institute of Biology.
