National…

Examines the treatment of errors and significant figures in physics manuals as part of an evaluation of these instructional materials. Comments on specific materials reviewed are provided. (JN)

Content, readability, safety aspects, appearance, technique, effectiveness of experiments, enrichment exercises, teacher aids, and special features of 12 physics laboratory manuals are reported and compared. (JN)

Briefly considers the nature of physics laboratories and their role in the physics curriculum. Also considers three valuable outcomes of laboratory experiences: using equipment, doing real experiments, and handling phenomena. (JN)

Forty-nine physics experiments are included in the teacher's edition of this laboratory manual. Suggestions are given in margins for preparing apparatus, organizing students, and anticipating difficulties likely to be encountered. Sample data, graphs, calculations, and sample answers to leading questions are also given for each experiment. It is…

Because of the daily impact of biotechnology, it is important that students have some knowledge and experience with biotechnology in order to enable them to deal with the issues that arise as a result of its implementation. The purpose of this workbook is to assist in the efforts to expose students to the concepts of biotechnology through hands-on…
