Investigates the ways children used their schemes of fractions to interpret fraction situations. Records clinical interviews with nine children (grades three through five). Reports that children do not establish relationships among different schemes when giving meaning to a given situation. (Author/YP)

Describes a course including both theory and practice in the uses of calculators and microcomputers for secondary school mathematics teachers. Provides four calculator activity sheets and an evaluation questionnaire. (Author/YP)

Presented are 19 abstracts of research papers produced by participants in the Regional Centre for Education in Science and Mathematics' (RECSAM) courses from 1985 to 1987 covering learning and teaching in science and mathematics education. (Author/YP)

To obtain reliable and valid measures of cognitive development in group settings, the Test of Logical Thinking, a paper-and pencil test of formal reasoning ability, was developed. It was administered to high school stuents, and alternate forms were then devised. Applications are discussed. (MNS)

Attitudes toward science of 654 pupils aged 14-15 were assessed, and relationships between attitude and locality, achievement, and sex studied. Achievement was mildly correlated with attitude, but locality and sex had no influence. Other findings are also discussed. (MNS)

A group test of formal thinking was administered to all grade 11 entrants in National High Schools in Papua New Guinea, and readministered two years later. Only 8 percent operated formally on the initial test; two years later, 18 percent were operating formally and 37 percent were at a transition stage. (MNS)

This study sought to obtain insight into the pattern of relationships between students' achievement in science and study behavior variables. Surveyed were 17-year-olds in the science stream of two secondary schools in Kuala Lumpur. Sex differences were found. (MNS)

Twenty-nine students in grades four, six, and eight were asked to find solutions to fraction equivalence problems and to verify their solutions using discrete material. Discontinuities were observed between strategies students used for producing solutions and supporting knowledge grounded in physical reality. (Author/MNS)

Three different models with continuous materials, discontinuous materials, and number lines were used to study the operation concept in six investigations on multiplication with fractions with pupils aged 11-12 in a Penang International School. All approaches could be understood by pupils, but they preferred the area and fractional models. (MNS)

Presents a readability formula and compares it with existing formulas and procedures. The formula uses reader feedback (identifying unclear words, sentences, paragraphs, figures, tables, and equations of reading material) and is considered appropriate for science and mathematics curriculum materials. (JN)

Proposes that computing is, in itself, a valuable discipline that should become part of the school curriculum, even for young children. Instructional strategies and suggestions for teaching programing are offered. (JN)

Discusses three aspects of Philippine culture that affect teaching and learning: (1) social structure; (2) language; and (3) values. Findings from cognitive growth research with Filipino children and adolescents are examined to identify ways of overcoming some sources of difficulties in these areas. (Author/JN)

Discusses the meaning of calculation errors, describing two error types (truncation and roundoff errors). Examples of calculator calculations are given to illustrate the importance of an awareness of significant digits and the effects of errors that may lead user to a mistaken interpretation of calculated results or to faulty conclusions.…

A model is being developed to categorize problems in teaching and learning mathematics. Categories include problems due to language difficulties, lack of prerequisite knowledge, and those related to the affective domain. This paper calls on individuals to share teaching and learning episodes; those submitted will then be compiled and categorized.…

Discusses the need for curriculum evaluation in mathematics as well as in other disciplines. Also discusses methods and techniques of curriculum evaluation, some of which are particularly relevant to evaluating mathematics curricula. (Author/JN)
