This paper provides a historical review of the interview research that has been used by science educators to investigate children's basic astronomy knowledge. A wide range of strategies have been developed over the last 120 years or so as successive teams of researchers have endeavoured to overcome the methodological difficulties that have arisen.…

Objective: This review considers the impact of chromosomal studies on the understanding of childhood neuropsychiatric syndromes, highlighting key discoveries, advances in technology, and new challenges faced by clinicians trying to interpret recent findings. Method: We review the literature on the genetics of child psychiatric disorders, including…

This issue of "Investigations in Science Education," provides analytical abstracts, prepared by science educators, of research reports in the areas of instruction, Piagetian studies, and teacher education. Each abstract includes bibliographical data, research design and procedure, purpose, research rationale, and an abstractor's analysis…

Abstracts and abstractors' critiques are presented for six studies dealing with concept formation and misconceptions and for five studies dealing with cognitive development. The first six studies investigated: children's naive conceptions of the human body; students' understanding (or misunderstanding) of states of matter and density changes; the…

Presented are abstracts and abstractors' analyses of four studies dealing with cognitive development, four studies dealing with attitudes, and two studies dealing with problem-solving. The cognitive development studies are: "College Chemistry and Piaget: The Relationship of Aptitude and Achievement Measures" (David Bender and Louis…

The measurement of the affective (qualitative) influences of computer-assisted interactive video instruction on the learner and attendant enhancements for the overall learning experience are highlighted. Formal factors considered are interactivity via buttons and other event-oriented objects, hypertext, semantic memory, and successive…

The complex interactions between picture, text, and learner are examined, based on a 3-D model which describes the context of the learning task. The different strategies that children of various ability levels use in reading from illustrated texts are described. (KR)

Describes a theory of learning in which the brain is seen as a Darwinian machine. Argues that the generative heuristic underlying Darwinism offers considerable value for technology and science education. Contains 33 references. (Author/WRM)

This symposium examines the science education research enterprise from multiple theoretical perspectives. The first paper, "Contextual Constructivism; The Impact of Culture on the Learning and Teaching of Science (William Cobern), focuses on broad issues of culture and how constructivism is affected by the context of culture. Culturally based…

Examines research in developmental psychology and science education that has attempted to assess the validity of Piaget's theory of formal thought and its relation to educational practice. Position papers (with little or no empirical support) are not included. (Author/JN)

An overview that gives an introduction to the theories, terms, concepts, and prior research conducted on visualization is presented. This information is to be used as a basis for developing spatial research studies that lend support to the theory that the engineering and technical design graphics curriculum is important in the development of…

Examines the role of empirical evidence in the interpretation of psychological and epistemological aspects of Piagetian theory. Concludes that Galileo's method of idealization has important implications for the construction of a neo-Piagetian epistemological theory. Contains 35 references. (Author/WRM)

Piaget's formal operational stage is related to the teaching of science by focusing on the development of paper and pencil tests for determining students' cognitive level of development and on procedures for helping concrete operational students improve achievement and become more formal in their thinking. (JMF)

Prescriptions for improving student understanding and problem-solving performance related to transmission genetics are discussed. Research on novice/expert problem-solving in transmission genetics is reviewed. (Author/CW)

Focuses on a single rule of grammar to produce evidence of a memory system for language acquisition and processing that is modular; independent of real-world meaning; unaffected by frequency and similarity; sensitive to formal distinctions; more sophisticated than the explicitly-taught rules it subsumes; developed independently of ambient input;…
