Presents a worksheet on graph paper that allows students to determine the perpendicular bisectors of given segments by folding the paper. Students then determine the slopes of the perpendicular bisectors and use inductive thinking to discover the relationship between the slopes of perpendicular lines. (MDH)

This review features new examples of using the computer relative to college-level mathematics to enhance pedagogy, solve problems, and model real-life situations. Included is a LOGO program that can be used to create and to stimulate subsequent investigations of spirolaterals, those figures generated by repeatedly drawing basic loops. (JJK)

Describes the teacher's guide made up of 125 student activities encompassing 1 year of high school physics instruction called Physics Resources and Instructional Strategies for Motivating Students (PRISMS). The learning cycle of each activity includes three phases: exploration, concept introduction, and concept application. Provides exploration…

This publication is a practical guide for teachers to improve their questioning techniques and thus increase their students' motivation, participation, and higher-level thinking. Teachers are urged to re-examine their views on educational practices and develop a teaching plan which accentuates opportunities for student involvement, and allows…

Many primary school teachers feel a lack of confidence in teaching science and technology. This paper aims to demonstrate useful and practical strategies for non-specialist science teachers to use in stimulating a positive scientific attitude among primary school students. It proposes that teachers should strive to develop children's natural…

The Invent America program addresses the need to provide K-8 students with opportunities to learn critical and creative thinking skills through the process of inventing. Students apply problem-solving skills as they turn their own creative ideas into inventions. It is an effort to integrate the curriculum, help students synthesize knowledge, and…

Eight papers which discuss rational and nonrational modes of knowing and consciousness and their relevance to educational practice are presented. Richard Jones in "Looking Back and Forth on Consciousness" considers two modes, the rational and the metaphoric, in a discussion of dreams. Alfred Kuhn discusses random variation and selective retention…

A CONCEPT ATTAINMENT TASK IN WHICH CHILDREN ARE ASKED TO IDENTIFY A CONCEPT THROUGH DETERMINING WHICH OF A SET OF OBJECTS ARE OR ARE NOT INSTANCES OF IT WAS USED TO INVESTIGATE THEIR PROBLEM-SOLVING BEHAVIOR. OF PARTICULAR INTEREST WAS THE QUESTION OF TO WHAT EXTENT THEY USED OR LEARNED THE STRATEGY OF VARYING ONE FACTOR WHILE HOLDING ALL OTHERS…

Chapter I provides a rationale for teaching science to young children; Chapter II discusses various ways children can learn science concepts; Chapter III gives suggestions on collecting and making materials and equipment, arranging the science area, planning outdoor learning, making science experiences happen, asking questions, etc. Chapter IV…

The roles of (1) the sequence of instruction and (2) cognitive ability variables were investigated using a computer-assisted instruction (CAI) course on an imaginary science of "Xenograde systems." A rationale for an information processing task analysis was developed to overcome the deficiencies of other analytic methods. The new method was found…

Reviewed are three computer software programs: (1) "World GeoGraph"--geography, discovery tool, grades 6-12, Apple IIGS; (2) "Grammatik III"--language arts, grade 7-adult, IBM, PS/2, Tandy 1000; (3) "Words & Concepts I, II, III"--language and concept training for special education, age 3-9, Apple II with speech…

Explores the use of dialogue and dramatization to reconstruct the formation of mathematical concepts. An appendix provides the synopsis of a 6-scene play that portrays the rise of negative numbers over a period of 300 years. (MDH)

Discusses the following themes that pervade individual articles in this volume: (1) critical reasoning; (2) inductive anthropology; (3) active learning; (4) discovery; (5) open versus closed anthropology; (6) reflexivity; (7) cross-cultural comparisons; (8) films; (9) holism; and (10) problems in the 1990s. Suggests that these themes will be at…
