Reports on conceptual understanding and solution strategies for percent problems of (n=31) students representing 2 ability levels from grades 5, 7, 9, and 11. Strategies evolved from intuitive to formal and increased in diversity with increasing age. Appendix includes concept and computation interview questions. (Contains 15 references.) (MKR)

This special journal issue presents a review of science education research in 1989. This summary of research is organized around 14 themes: achievement in science, affect, classroom interactions, cognitive processes, computers, curriculum, instruction, legislation and policy, misconceptions, scientific literacy, teachers, tests and assessments,…

Discusses Vee mapping, a technique to assist students in categorizing the relationship between the conceptual and procedural aspects of science. Presents a study to investigate elementary education majors' (n=27) use of the Vee heuristic and concept mapping for the construction of knowledge; attitudes toward learning science in collaborative…

This paper examines ways in which coherent reasoning about key concepts such as variability, sampling, data, and distribution can be developed as part of statistics education. Instructional activities that could support such reasoning were developed through design research conducted with students in grades 7 and 8. Results are reported from a…

In this article knowledge productivity, a process that creates conceptual artifacts, is used as a way to investigate the outcomes of collaborative and enquiry-oriented activity by teaching professionals. It is an outcome of the motivation to learn (self-regulation) in that it studies the issues from different professional perspectives (reflection…

A study was designed to describe how middle school students select, link, and determine relationships between textual and visual information. Fourteen authoring groups were formed from both eighth-grade earth science classes of one veteran teacher in one school. Each group was challenged to produce an informative interactive laservideodisc project…

This document contains plenary and contributed papers presented at the seventh PME meeting, held near Jerusalem, Israel in July 1983. Three plenary papers focused on implicit models in solving problems, discussions with teachers and children, and heuristics. Contributed papers were classified under seven headings: learning theories…

This publication contains a selection of science education research papers, beginning with an overview of trends in science education cognitive developmental research and theory in the United Kingdom. Papers that follow focus on developments in studies of thinking and reasoning, including work on concept mapping and conceptual change. Closely…

This paper advocates an integrated curriculum in which LOGO would play a role in the intellectual development of children. In particular, it is argued that curricular interventions that occur in the midst of spontaneous learning are most needed when major problems of transfer, generalization, and abstraction are to be solved or when children need…

Major efforts are underway to identify and define a science of science education which will reverse the relationship between research and program development. This trend is toward using research on how learners grow and develop prior to program development and the organization of instructional techniques. Clear scientific explanations of how…

This issue of "Investigations in Mathematics Education" contains: (1) a review of E. Fischbein's book "The Intuitive Sources of Probabilistic Thinking in Children;" (2) nine abstracts of research studies in mathematics education; (3) a list (by EJ number) of mathematics education research studies reported in the January to…

This document consists of two issues of the journal "Seedbed," an outcome of the Teachers' Center Project at Southern Illinois University at Edwardsville. Designed to be neither scholarly nor trivial, each issue is a collection of teachers' ideas that they thought worth sharing with other teachers as "seedlings" to be developed, helping teachers…

Sixty-four high school students, stratified by field-dependent or independent cognitive style, were randomly assigned to homogeneous or heterogeneous groups of four to attain concepts in the sequence of complex to simple or simple to complex, with either minimal or strategy instructions. Subsequently, each student individually attained four…

The College Entrance Examination Board's Decision-Making Program is a course of study in the development of decision-making skills, designed for students in junior and senior high schools. It consists of student and leader materials that may serve as a basis for a school guidance program, as a major component for a school-wide decision-making…

The paper describes the rationale and 10-day implementation in a 5th-grade classroom (n=19) of an experimental ratio-and-proportion instructional design. In this constructivist-phenomenological design, coming from our theoretical perspective, design research, and domain analysis, students: (1) link "real-world" and "mathematical" objects…
