This research paper examines phylogenetic tree construction-a form of problem solving in biology-by studying the strategies and heuristics used by experts. One result of the research is the development of a model of desired performance for phylogenetic tree construction. A detailed description of the model and the sample problems which illustrate…

Introduces a general theory of sociobiology which a biology teacher would find useful as a basis for course development. (LS)

This paper, which analyzes the evaluative aspect of affectivity, argues that the functional internalization of organic evolution for the formation of the intellectual system of human beings required that some means of selecting behavioral variations be devised, and that the selective mechanism devised was the affective system. From this…

The creationism evolution controversy has become a problem of major concern in many states, especially Arkansas and Louisiana, and is the basis for dispute in many courts. Creationists, sensing the need for a modern approach, have now become less concerned with the theological rationale for their argument and have turned to the scientific field as…

Reports the current situation in a number of states regarding the controversy of teaching evolution and creatonist theories in science classes. (JR)

This text contains units 15-16 in the Open University course, Science and Belief: from Copernicus to Darwin. It is an inter-faculty second level course in the history of science. Unit 15 is concerned with Nature and History and includes uniformitarianism, human history, evolutionism, and Darwinism. Unit objectives, readings, and questions with the…

Concepts of the human environment through a systems approach are presented. Principles of systems thinking which assist the student to study subjects with a comprehensive view of the way topics are interrelated with each other, rather than considering subjects in isolation, are discussed. Part One introduces systems concepts. Part Two deals with…

DEVELOPED AND SUBJECTIVELY EVALUATED ARE INSTRUCTIONAL MATERIALS FOR USE IN AN INTRODUCTORY COLLEGE LEVEL GENERAL EDUCATION BIOLOGY COURSE, WHICH EMPHASIZES THE DYNAMIC AND INVESTIGATIVE ASPECTS OF SCIENCE. THE MATERIALS, WHICH USE A CASE HISTORY APPROACH, WERE DEVELOPED BY EDITING EXCERPTS FROM CLASSICAL SCIENTIFIC PAPERS WITH ADEQUATE EDITORIAL…

This is an in-depth course of study of the historical attempts to explain the evolutionary process and of recent developments pertinent to the study of biomedical evolution. Topics included in the module are: (1) ancient concepts of the evolutionary process; (2) various aspects of Lamarckism, Darwinism and neo-Darwinism, including substantiating…

Eighty-eight secondary school biology textbooks published between 1900 and 1968 were examined to determine the extent that forty-four topics related to the concept of evolution were emphasized. Prior to 1960 there was a cursory, non-controversial treatment, with a gradual increasing emphasis up to 1950. In the 1950's this trend reversed slightly.…

Nuffield Secondary Science is a set of tested materials from which teachers can prepare courses for students in grades 9-11 (approximately) who do not intend to major in science. The materials are designed for British secondary schools but are adaptable to other countries. The Teachers' Guide to the entire set of Themes is described in SE 015 440…
