Recent research in science education examines learning from four foci: (1) concept learning; (2) developmental; (3) differential; and (4) problem-solving. These perspectives provide a framework for identifying mechanisms of change in knowledge/thinking processes. In-depth coverage of several science topics may benefit students more than fleeting…

Reported is a study to investigate the effects of a free-choice program on children's ability to interpret experiments, design simple investigations, and recognize variables that could affect the outcome of observed events. (Author/SA)

How students restructured their scientific ideas in response to contradictions was studied with 166 male and female students (aged 12 to 14 years) who tested their predictions about water displacement by experiment. Conceptual change varied; all subjects tended to hold onto old ideas, even when presented with conflicting information. (SLD)

Discusses: (1) potential advantages of learning computer programing, (2) performances of males and females in middle school programing courses, (3) problems teachers face in achieving this potential, and (4) participation of males and females in programing courses. Results show females, on the average, perform as well as or better than males.…

Research on the development of ability to control variables during adolescence is reviewed. The first section discusses studies by Piaget and his collaborators, replications of Piaget's studies, and related studies by other investigators. Factors which influence performance on controlling variables tasks are delineated; the existence of Piaget's…

A developmental investigation of the ability to control variables was conducted. One or two logically similar physics problems were individually administered to 120 subjects age 12 to 14. The problems involved either familiar or unfamiliar variables. Each problem was presented in three different informational formats. Success on the problems in…

This study of Piagetian formal reasoning in seventh grade students reports the relationships between four aspects of the ability to control variables in an experiment and the relationships between those four aspects and other constructs. The four aspects of the ability to control variables identified are: (1) set up a controlled experiment, (2)…

Characterizes gap between potential of computers in education and their performance in classrooms; documents differential participation of males and females in computer experiences and discusses contributory factors; describes two studies of how males and females respond to computer learning environments; and suggests actions to foster equitable…

Describes a study of junior high students which investigated academic achievement and higher cognitive skill development outcomes of a computer programming course in which two augmentations to traditional BASIC instruction were compared. A model for understanding learning outcomes is presented, suggesting ways to augment instruction to focus on…
