EIGHT INSTRUCTIONAL TESTS SPANNED THE CURRICULUM OF ONE YEAR OF BIOLOGY STUDY. THE FIRST CONCERNED THE NATURE OF SCIENCE INCLUDED 4 AREAS OF EMPHASIS--THE NATURE AND FUNCTION OF HYPOTHESIS, THE IDEA OF CONTROLS IN EXPERIMENTS, INTERPRETATION OF GRAPHED DATA, AND THE NATURE OF DATA. THE SECOND TEST WAS DESIGNED TO SHOW AN UNDERSTANDING OF BIOLOGICAL CLASSIFICATION WITH 3 AREAS OF EMPHASIS--RELATIONS OF TAXONOMIC GROUPS, THE BASIS OF BIOLOGICAL CLASSIFICATION, AND CONCEPT OF SPECIES. THE THIRD TEST CONSIDERED THE CHANGES IN LIVING THINGS WITH THE FOLLOWING AREAS OF EMPHASIS--EVALUATION, SPONTANEOUS GENERATION, ADAPTATION, VARIATION, AND THE NATURE OF SCIENCE. THE FOURTH TEST COVERS THE CHEMICAL BASIS OF BIOLOGY, WITH EMPHASIS ON UNDERSTANDING OF SELECTED IDEAS REGARDING UNITY IN LIVING THINGS AND OF WAYS IN WHICH MOLECULES AND IONS MOVE IN LIVING THINGS. THE FIFTH TEST CONCERNED THE CELL PHOTOSYNTHESIS, CONTAINING 4 MAJOR AREAS OF EMPHASIS--THE CELL, CELL DIVISION, PHOTOSYNTHESIS AND ENZYMES. THE SIXTH TEST IS A FINAL EXAM FOR THE FIRST SEMESTER, COMPRISED OF MATERIALS ON THE NATURE OF SCIENTIFIC INQUIRE, THE THEORY OF EVOLUTION, CELL BIOLOGY, AND MULTICELLULAR ORGANISMS. IN ADDITION SIXTH TEST DEVELOPS 4 AREAS OF GENETICS--HISTORICAL DEVELOPMENT OF THE MODERN GENE THEORY, PROBABILITY, MENDELIAN GENETICS, AND BIOCHEMICAL ASPECTS OF GENETICS. THE FINAL EXAM EMPHASIZED EVALUATION, GENETICS, ENERGY RELATIONS, DEVELOPMENT, ECOLOGY, REPRODUCTION, NATURE OF SCIENCE, HISTORY OF BIOLOGICAL CONCEPTS, AND REGULATORY MECHANISMS.
