Scientists use judgment in deciding what and how much data to present in publications but science degrees rarely address this issue. Instead, scientific knowledge is presented as certain and students have limited opportunities to use their own judgment in the laboratory. A consequence of this may be that students approach science with a moral…

Examined relation between college students' (N=108) ability to solve simple ratio tasks (for example, their proportional reasoning patterns) and their rule-governed behavior with the balance beam. Also identified modifications in a set of rules for the balance beam tasks. Results and implications for science instruction are discussed. (JN)

Reports a study to determine if the formal capabilities of 81 elementary education preservice teachers would be enhoused from problem solving instruction with manipulative feedback or with pictorial feedback. Results indicate the manipulative mode was clearly superior in student attitudinal responses and achievement. (SL)

Assesses the level of intellectual development in proportional, combinatorial, and correlational reasoning and the ability to control variables in beginning sophomore students (N=207) at the American University of Beirut, Lebanon. Compares this level with their performance on achievement tests in mathematics, biology, chemistry, and physics. (CS)

Examines the role of metaphors in teaching science. Suggests that when such expressions are used correctly, they can greatly enhance learning. Argues that metaphors also enable students to create new and interesting formations of thought. (CW)

Discusses alternative perspectives on nature of knowledge and psychological development, relating these to science instruction. Indicates that significant learning occurs if facts have personal relevance, suggesting that a cultural transmission approach to teaching/knowledge dominates science education which neglects the role of students' personal…

This study, conducted in an Australian institution, investigates the intellectual requirements of the mechanics section of a first-year college physics text. Instructional and prerequisite concepts were classified in terms of the intellectual skills required to understand them. (HM)

Examined relationship between cognitive requirements of two chapters of a physics textbook for biology/pre-med students and their ability to use prerequisite reasoning skills required for its understanding. An average of 42 percent of students tested did not consistently use reasoning skills required to understand text concepts. Discusses tests…

Presented is a broad perspective of the state of knowledge in science education, a description of existing trends, the areas where research is needed, and tentative answers to persistent problems that have been identified from the research. (CS)

Examines changes in the broad cultural background which provide the context for thinking, and how such life-style changes may have influenced the decline of reasoning skills and styles fundamental to the sciences. Considers peasant/rural farming, new world, and postaffluent society life-styles and science education in the latter. (Author/SK)
