This publication contains a collection of research papers designed to be used as a supplement to the textbook in a high school biology class. The material can be used to enrich the curriculum by stimulating critical thinking and by making high school students aware of the ways in which scientists work. Some of the papers have been condensed or paraphrased so that a high school student could use the publication as part of an independent study program. The papers are grouped under the following headings: Unity among Living Things, Biology of Man, Biology of Plants, The Conquest of Disease, The Origins of Life, The Origins of New Organisms, The Transfer of Traits, and Observation and Experimentation. Also included is a two-page figure spanning the period 1550 - 1950 and showing when famous scientists lived along with contemporaries who achieved fame in other areas of endeavor. (PEB)

A PAPER PRESENTED TO THE SECTION ON EDUCATION (Q) OF THE 1967 AMERICAN ASSOCIATION OF SCIENCE ANNUAL CONVENTION, THIS DOCUMENT DISCUSSES THE ACTIVITIES OF THE DIVISION OF SCIENCE TEACHING (DST) OF UNESCO. INCLUDED ARE DISCUSSIONS OF (1) THE OVERALL PROGRAM BUDGET, (2) AN HISTORICAL PERSPECTIVE OF THE DEVELOPMENT OF DST AND ITS RELATIONSHIP TO THE EDUCATION SECTOR OF UNESCO, AND (3) A DESCRIPTION OF THE PRESENT OVERALL PROGRAM AND PROJECTIONS FOR THE FUTURE. THE PRESENT PROGRAM IS DESCRIBED UNDER ITS FOUR MAIN PARTS (1) COLLECTION AND EXCHANGE OF INFORMATION, (2) PILOT PROJECTS ON NEW APPROACHES AND MATERIALS FOR THE TEACHING OF BASIC SCIENCES, (3) OTHER ACTIVITIES TO IMPROVE THE TEACHING OF THE BASIC SCIENCES AT UNIVERSITY AND POST-GRADUATE LEVELS, AND (4) STIMULATION OF INTEREST IN SCIENCE. SPECIFIC PROJECTS AND PROGRAMS BEING CARRIED OUT UNDER EACH OF THE FOUR MAIN PARTS ARE DISCUSSED AND THE PRIMARY GEOGRAPHIC AREAS AFFECTED ARE INDICATED. A BIBLIOGRAPHY FOR THE PROVISION OF MORE DETAILED INFORMATION IS INCLUDED. (DS)

INCLUDED ARE MATERIALS FOR USE IN TEACHING AND EVALUATING 11 SELECTED CONCEPTS RELATED TO THE BIOLOGICAL CELL IN GRADES 2 TO 6. THE CONCEPTS WERE SELECTED AND THEIR ORDER DETERMINED THROUGH AN ANALYSIS OF ELEMENTARY TEXTBOOK SERIES, HIGH SCHOOL AND COLLEGE BIOLOGY TEXTS, CYTOLOGY TEXTS, AND INFORMATION GATHERED THROUGH A PILOT STUDY. THE MATERIALS HAVE BEEN EXPERIMENTALLY EVALUATED AND A BRIEF RESUME OF THE DATA IS PROVIDED. PART 1 DESCRIBES 11 LESSONS, ONE LESSON FOR EACH CONCEPT SOUGHT. THE LESSONS ARE DEVELOPED FOR ORAL PRESENTATION IN ASSOCIATION WITH APPROPRIATE VISUAL MATERIALS SUCH AS PHOTOMICROGRAPHS, ROCK SECTIONS, DIAGRAMATIC DRAWINGS, FILMLOOPS, AND OTHERS. PART 2 PROVIDES MULTIPLE-CHOICE TYPE TESTS FOR TESTING STUDENT KNOWLEDGE, COMPREHENSION, AND APPLICATION OF EACH OF THE 11 CONCEPTS. EACH TEST INCLUDES 36 ITEMS DIVIDED EQUALLY BETWEEN THE THREE LEVELS OF UNDERSTANDING. TEST RELIABILITIES ARE GIVEN. THE STUDY FOR WHICH THESE MATERIALS WERE DEVELOPED IS REPORTED IN FULL IN TECHNICAL REPORT NO. 40 OF THE CENTER FOR COGNITIVE LEARNING AT THE UNIVERSITY OF WISCONSIN. (DS)
