Discusses: how thought experiments (TES) are presented and used in physics textbooks; how and why teachers include TES in their explanations; and what understandings students draw from TES. Indicates that TES are only one of a broad class of "acts of imagination" which are essential in physics education. (JN)

Appraises current explanations of how visual processing occurs. Highlights the basics of simultaneous and serial levels of processing. Discusses the results of a series of experiments on visual-search tasks and also on the role of prior knowledge in processing. (ML)

Describes experiments which focus on the perception of three dimensions. Discusses the cues about distance and depth and the role they have in perceptions of three dimensions. Evaluates the effect of color on the illusion on depth. (ML)

Described is an in-class demonstration of mass reaction time which measures the speed of nerve impulses and the duration of various cognitive processes. A simpler version of the experiment for at-home use is described. (Author/DB)

Problem solving that both requires and develops higher-order thinking skills is illustrated in the EQUATIONS Challenge Matches program, which consists of computer diskettes at the elementary, intermediate, and advanced levels plus a multi-level diskette. Samples of computer output are given, with the results of various types of experimentation…

Discusses briefly Piaget's views on intellectual development as related to science teaching. Describes intellectual activities observed in science classrooms and shows how specific science lessons can be designed to encourage cognitive development. (GA)

Different effects of instructional strategies on recall and comprehension of terms frequently used in formal analysis of art were examined. The study looked at a synthesis of three theoretical positions: dual-coding theory, schema theory, and elaboration theory. Two-hundred and fifty sixth-grade students were randomly assigned to three groups:…

This study compared the effects of cooperative learning groups to traditional instruction in remediating students' misconceptions about temperature. Students from grades 3, 4, and 5 in two rural elementary schools participated in the study. Students completed a pretest, a cognitive conflict laboratory activity and a posttest that measured…

Tested the effectiveness of a program designed to teach children how to conduct and interpret a controlled experiment. Results indicate that the ability to control variables can be taught using the program (which consists of activities related to designing, building, and launching model rockets). (JN)

Science activities with soap bubbles for primary school children are described in this article. Another activity involves children in determining the whereabouts of sugar as it dissolves in water. (SA)

To cope with some social problems, Japanese educational planners are drafting some proposals for research into innovations in the educational system. This paper reports on some research recently done which looked into the relationships of the Japanese educational environment and the reasoning/thinking skills and process skills of students in…
