collection	Education Resources Information Center
contents	Science Library of Test Items. Volume Seventeen. A Collection of Multiple Choice Test Items Relating Mainly to Biology. Biology Foreign Countries Item Banks Multiple Choice Tests Science Tests Secondary Education Secondary School Science Test Construction Test Items As one in a series of test item collections developed by the Assessment and Evaluation Unit of the Directorate of Studies, items are made available to teachers for the construction of unit tests or term examinations or as a basis for class discussion. Each collection was reviewed for content validity and reliability. The test items meet syllabus content and aims best suited to multiple choice questions, but teachers are meant to base the use of the test items on student ability and the particular program objectives in grades 7 through 10. Test items related to the knowledge and application of information in biology are presented in sections on structural and process aspects of body systems, health and foods. There is also a section on plants. Test items on reproduction, genetics, classification, ecology adaptations and evolution complete the volume. There are 479 test items. Answers are provided with each item; drawings, tables and diagrams illustrate many questions. (CM)
