Identifies metaphor as a powerful tool when utilized to facilitate concept formation pertaining to global ecological systems and universal concerns. Provides an illustration of how an instructional metaphor, spaceship earth, can be used in the classroom to help students create new meanings for abstract and complex ideas. (MCO)

Presents a study conducted to investigate the subjective experiences of a teacher making the transition from a traditional textbook, content-dispensing approach to a problem-solving approach to teaching science. Although outward changes in teaching materials and strategy are evidenced, the teacher shows little change in beliefs about the teacher's…

Reports on the differences in two sections of a college course on differential equations. Results on a common examination showed that writing assignments substituted for traditional homework assignments did not improve test performance. However, survey results indicated that students felt the writing assignments, in lieu of additional homework,…

Examines the relationships between the development of proportional reasoning strategies and three cognitive variables from Pascual-Leone's and Case's neo-Piagetian theories: (1) degree of field independence; (2) M-space; and (3) short-term storage space. Describes the ability of students to transfer problem-solving schemata to new contexts as well…

This study described ways that sixth grade students invented strategies for working out difficult physics problems while using a motion program in the computer environment "Boxer." Strategies became a communal classroom resource and ground rules for their use were negotiated with the teacher. (MDH)

Describes a desktop publishing project that uses computer-assisted instruction to engage students with severe behavioral problems in a more active learning environment. Topics discussed include the reinforcement from computers; benefits of computer-assisted instruction; hardware and software selection; staff training; evaluation; and future…

Outlines a course designed to enable distance teachers to develop and teach courses using computer-mediated communication and emphasizing basic pedagogy. The teaching strategies and learning points of each module, as well as the organizational and technical set-up, are described. (Contains seven references.) (EAM)

Argues that designing aids and tools to perfect the mind is one of the primary goals of educational research. It discusses the need for appropriate theories to design instructional materials and methods and explains why school practices have not changed to reflect advances in the understanding of learning and development.

Fifty-five males with learning disabilities and 55 average-achieving males in grades 6-7 studied paired associates of varying difficulty levels, through image construction or pairing rehearsal. Regardless of item type or presentation rate, both groups of students benefited from imagery instructions, with great similarity in between-condition…

Challenged is the traditional model for the transmission of mathematics in the elementary school classroom. An inquiry approach to learning mathematics is proposed and supported with results of a year long research project that exposed second graders to mathematical learning experiences using this approach. (MDH)

This study examines the effect of formal representation of blue and yellow color mixtures as rational numbers on students' ability to solve ratio problems comparing the mixtures. Sixty subjects participated, 20 from each of grades 7, 8, and 9 from a Haifa (Israel) junior high school. Introducing the formal representation improved performance for…

Describes a textbook production project in a Central American country whose goal was the improvement of primary education. Disparities between educational opportunities in developed nations and Third World nations are discussed, and problems with the project that prevented it from meeting its goal are described. (32 references) (LRW)

Researchers tried training preservice teachers to make clearer presentations and produce greater student learning and satisfaction. Subjects received training in 17 instructional clarifying behaviors. Researchers videotaped their teaching pre- and posttraining. Learners rated content and satisfaction. Results indicated significant improvement in…

Describes discovery learning, a teaching method that encourages students to use inductive reasoning. Students explore and experiment using the skill or idea being taught; they determine rules, make generalizations, and discover concepts. The teacher acts as coach, advisor, and reinforcer. A student page offers a discovery learning game on capital…

Beginning geometry students misunderstand the requirements of formal proof because of confusion between deductive reasoning and argumentation. Presented is a cognitive analysis of deductive organization versus argumentative organization of reasoning and the applications of this analysis to learning. Implications of a study analyzing students'…
