Groups of retarded and nonretarded children were investigated as they learned three rules underlying problems adapted from the Raven Progressive Matrices Test: rotation, imposition, and subtraction. Results were seen as consistent with theories that emphasize transfer flexibility as one potential source of individual and comparative differences in…

Presents thinking-aloud protocols from secondary pupils solving arithmetic story and geometrical problems and analyzes their protocols by using interpretation models founded on a general problem-solving model. A word problem solving simulation is also used to further explicate processes pupils use to solve mathematical tasks. (Author/MBR)

Examines the impact of high technology on society and the need for curriculum change to prepare students for the future. Discusses the skills needed for life-long learning, including ability to access information, critical and creative thinking, decision making, problem solving, and flexibility and adaptability. (JHZ)

Explains how a Forensic Science and Criminology unit can help in the development of science process skills, mastery of laboratory techniques, and assist in value clarification. Examples of investigations and activities that have been successful with fifth- and sixth-grade students are included. (ML)

Reports on a study done with the intentions of determining the relative contribution of eight variables in predicting environmental behavior. Concluded that the major predictors were skill in using environmental action strategies, level of environmental sensitivity, and percieved knowledge of environmental action strategies. (TW)

Describes a computer program written in Microsoft BASIC for use on personal computers to calculate travel times of refracted waves in layered structures with arbitrary dipping interfaces. Exercises for student use are given to illustrate some of the basic properties of reversed refraction travel time graphs. (TW)

Presents practical teaching suggestions selected from commercially available materials and also submitted by readers that can be easily adapted to different grade levels. Includes seven computer-based activities on topics such as map-making, word games, database logic, concatenation, and one-line programs. (ML)

Suggests ways that colleges can improve the problem-solving skills of chemistry majors and acquaint them with the realities of industrial research. Describes two projects in which undergraduate chemistry majors performed research and development work for a local chemical company. (TW)

New approaches to the teaching of introductory algebraic concepts are discussed. Their use in the Approaching Algebra Numerically Project in some middle schools in Ohio is reviewed. Some implications for use in Australian schools are considered. (MNS)

Activities to extend the core curriculum through the study of the periodicity of rational numbers to help students develop calculator and research skills are presented. Four worksheets are included, to be used as discovery activities. A computer program is listed, as well as examples of periodic pictures. (MNS)

Discusses the results of a study on the limitations of short-term memory in terms of its implications for the teaching of chemistry and problem-solving skills. Also includes a description of the Saskatchewan life skills program for disadvantaged adults for coping with change. (ML)

Provides an annotated list of references for educators on using computers in the classroom and for researchers in gathering background materials for the preparation of articles, grant proposals, and presentations. Focuses specifically on probability and computers. (ML)

Described is a project in a third grade class in which problem-solving skills are developed through activities with patterns. Activities for growing picture patterns, making number tables, and developing open sentences or formulas are discussed and illustrated. (MNS)

Compared "extended discretion" (ED) learning approach to traditional Biological Sciences Curriculum Study (BSCS) laboratory investigations. Found that although ED students are more capable of exercising independent judgment for greater lengths of time while BSCS demanded more teacher time, all teachers were still reluctant to accord…

Some applications of ratio and proportion to scale drawing involving geometric figures are given. The activities or problems concern the earth and space, scale speeds, and the earth-moon system. (MNS)
