BIOCHEMICAL EDUCATION

July 1976

This has proven to be an instructive and challenging experiment for junior and senior college students who have had one year of organic chemistry and one quarter of biochemistry lecture.

This useful publication contains the proceedings of an international symposium on the subject held in Madrid, 6-7 September 1975. It consists of 10 symposium papers followed by brief reports from many countries. The titles of the papers are: Enhanced Potentialities of New Educational Technology. Developments in the Tools of Educational Technology in Chemical Education During the Last Decade. Educational and Other Factors Affecting the Selection of Techniques for Effective Teaching. Mass Media and Chemical Education. Effectiveness of Tools of Modern Educational Technology in the Teaching of Chemistry in the Classroom and Laboratory. Programmed Learning in Chemistry: Where do Computers Come in? Computer-Assisted Instruction on Chemical Education. Educational Technology in Developing Countries: Problems and Challenges. International Cooperation ih Educational Technology.

Each of the papers is followed by a bibliography which in some cases extends to more than 200 references. There is no doubt therefore that this is a most useful compendium and represents a sound book for biochemists. Sometimes I found the Chapters rather dull reading in that they consisted of lists of techniques and references, in other cases the author seemed to be overdoing his enthusiasm but in general the approach is relatively realistic. In this respect I thought that L. J. Haynes, of the Open University, in his consideration of "Mass Media and Chemical Education" was especially interesting. He emphasizes that radio and T.V. are used for "Enrichment" rather than direct teaching and I am sure that this is a general truth. I rather suspect that the most useful aspect of the new technology is to bring the contents of courses and the way they are taught out into the open. Too often is teaching a private matter between teacher and taught. The discussions which the technology leads to should cause a reappraisal which can only do good. Even if they only make the teacher seem more enthusiastic they will have been worthwhile. Its good to see IUPAC and their Committee on Teaching of Chemistry making such an effort for the world needs chemists and we have got to find a way of presenting this hard science in an interesting manner.
