The 1982 Search for Excellence in Science Education project has identified 10 exemplary programs in biology. Descriptions of the programs and the criteria used in their selection are presented. Chapter 1 discusses the desired state in biology education, examining the goals of biology education and how these goals relate to biology curriculum and instruction. These goals, which focus on personal needs, societal issues, fundamental knowledge, and careers, were among the criteria used for defining excellence in these programs. Chapters 2 to 11 provide descriptions of the exemplary programs (including programs in limnology, marine biology, ecology, and health). The descriptions include: information about the setting of the program (community location, size, specific features, school science, and organization); nature of the program (grade, level, class sizes, curriculum outline, learning activities, evaluation techniques); origin of the program; and what factors contribute to the program's success and what is needed to keep it going. Chapter 12 synthesizes the ideas found in these programs and offers generalizations and recommendations related to excellence in biology programs. For example, excellent programs were found to consider values and ethics related to personal decisions and social policies and to focus on social issues and relations between ecology and the community.
