This paper describes a computer-simulation model of the way in which basic reasoning processes develop in children. The model, based on PRISM-II programming language, was designed to reflect the manner in which world knowledge can be used to construct strategies for reasoning. The model learns strategies for performing transitive inference by…

The National Guidelines for Comprehensive Sexuality Education were developed by a Sex Information and Education Council of the United States (SIECUS) task force made up of health, education, and sex education professionals. The group was tasked with formulating sex education concepts and guidelines within four developmental levels, from…

This paper reports on part of a five-year research study on the implementation of new industrial chemistry case studies into the curriculum for students majoring in chemistry in Israeli high schools. The purpose of the study was to obtain information on teachers' formal education in industrial chemistry and their attitudes toward teaching this…

This study reports on the historical conceptualization among Finnish 12-13 year-olds who were given a projective task to yield historical thinking. The case study examines expressions the subjects used and which were studied qualitatively, using "chunks of meaning" as units of analysis, in regard to both their meaning- content and their…

This study investigates the relationships between student beliefs about the nature of science, student attitudes, and conceptual change about the nature of forces in a traditional high school physics classroom. Students (N=28) in the study were junior-level high school honors students in an introductory physics class. The physics instruction was…

This book represents a compilation of the views and ideas of the late Hans Freudenthal, representing his last major contribution to the field of mathematics education. Rather than a presentation of new views, Freudenthal selected and streamlined old ideas, many gathered from his lectures in China, and formed a review of questions and issues in…

Three different theory of mind tasks were conducted with 4- to 8-year-old Quechua peasant children in the Peruvian Andes. The study investigated the ways in which children in preliterate cultures think and the possibility that they think differently than children in literate cultures. The tasks included: (1) a false-belief task, which tested the…

A possible method of solving problems of knowledge representation and system adaptation in a hypermedia environment was examined. The method, based on the notion of semantic networks, uses the technique of knowledge mapping. In the process of reading a hypermedia document, the learner constructs a knowledge map (KM) specifying the relationships…

A study investigated the interaction of cognitive, cultural, and linguistic factors in second-language concept formation in adults. Specifically, it examined how seven college students in a lower-division intensive Spanish class developed new gender concepts when learning a second language. Course instruction focused on concept construction at…

The purpose of this study was to examine how students acquire their knowledge through peer collaboration in a new educational environment called "Computer Supported Intentional Learning Environment (CSILE)." Twenty-seven 5th- and 6th-grade students were instructed to create their collective database for a study topic,…

Distillation in the chemistry laboratory is an essential part of a practicing chemists' and a chemistry educators' work. Nevertheless, regardless of the degree of importance in each of the aforementioned professions, few educational studies on teaching and learning distillation exist. In an effort to rectify this oversight, the Department of…

The purpose of this investigation was to compare the knowledge regarding marine organisms and their feeding relationships of fourth grade residents of one coastal and one inland community in south Texas and to generate grounded theory concerning the participants' construction of such knowledge. Four male and four female students were randomly…

The first of two parts in this document is a student workbook which is designed to teach students how to construct a concept map, i.e., a graphic arrangement of the key concepts in a body of subject matter with connecting lines labelled to show valid and meaningful relationships between the chosen concepts. The workbook provides a discussion of…

References to Lev Vygotsky have become fashionable in discussions of learning in the last few years. Drawing upon Vygotsky to explain small groups is speculative, as he never examined small groups. While the mechanics of small groups are important, they are only important if the overall culture of the classroom is supportive of students' effort to…

Educators can help themselves and others improve their creative thinking. Before the improvement can begin, there must be a common understanding of what creativity is. Edward Land described creativity as the sudden cessation of stupidity. Several barriers to creative thinking include boredom, lack of challenge, believing expertise in a particular…
