This article analyses some typical consequences of a specific research policy on experimental research in biology. The policy is conducted by a national funding agency--the Swiss National Science Foundation--through a particular programme, the "National Centres of Competence in Research" which is designed to promote both "scientific…

Presented is a study in which students' intellectual reasoning development was evaluated following instruction that emphasized formal operations in a traditional lecture format. Results indicated that formal-operational students had significantly more success in the three reasoning areas than transitional students and transitional students had…

Discussed is the relationship of concept-mapping by students to the meaningful learning of genetics and ecological concepts. The implications of these results for teacher education in biology are addressed. (KR)

Investigated were student problem-solving strategies in an attempt to develop a model of student performance. The problem-solving strategies used by 30 high school students were analyzed. Suggestions for improved instruction in solving genetics problems are provided. (CW)

There are two major concerns about the teaching of high school biology. One is the degree to which students memorize laws, facts, and principles, and the second involves the role of the classroom teacher. These aspects result in a discrepancy between the theory and practice of science education. The purpose of this report is to provide: (1) a…

Examines various types of problems that researchers have used to demonstrate problem solving. Focuses on genetics problems. Discusses classes of learning outcomes, conceptual knowledge gains, content-independent heuristics, content-specific procedures, understanding the nature of science and a typology of genetics problems. (CW)

One aim of this study was to identify, in a group of unsuccessful college level problem solvers, the status and use of their declarative knowledge as revealed by students' attempts to solve novel problems in a pencil-and-paper setting. It was hypothesized that for some unsuccessful problem solvers, their problem representation could be improved by…

The purpose of the research was to manipulate two aspects of genetics instruction in order to measure their effects on college, introductory biology students' achievement in genetics. One instructional sequence that was used dealt first with monohybrid autosomal inheritance patterns, then sex-linkage. The alternate sequence was the reverse.…
