Geometric activities for junior high school students at the first levels of the van Hiele model of geometric learning (recognition, analysis, and ordering) are discussed. Illustrative problems are included.

Description of a validated computer assisted instruction (CAI) program (The Addition Tutorial) illustrates how four critical components for instruction--learning principles application to instructional design; sufficient database; adequate motivational system; and delivery system which provides teacher learning environment control--might be…

Discusses conception, design, implementation, and evaluation of a calculus course that utilizes a multi-user microcomputer system with graphics terminals. The numerical and utility routines of the software are briefly described, and examples of several types of calculus problems that can be solved utilizing the system are reviewed. (Author/MBR)

Documents the educational use of spreadsheets through a description of exploratory work which utilizes spreadsheets to achieve the objectives of Conway's Game of Life, a scientific method game for the development of problem-solving techniques. The implementation and classroom use of the spreadsheet programs are discussed. (MBR)

Computer-assisted-instruction software was developed to supplement the conventional lecture-laboratory mode of instruction with another instructional aid for learning science in an individualized, nonthreatening environment. This development project was designed to teach physical concepts, mathematical techniques, and problem solving strategies.…

Primary school teachers tended greatly to overestimate the scores that their students would achieve in mathematics and English achievement tests and to greatly underestimate the scores they would achieve in the reading achievement test. Factors that influenced teachers' judgments include academic competence, student relationship with the teacher,…

Recognizes two critical factors in cross-cultural mathematics teaching: the perceived utility of mathematics and the direct relationship of mathematics learning to language development. Reviews current literature and reports the results of their study of perceived utility of mathematics and technical language development in the Crow Indian…

A Chicago program that had nonscience faculty attend science classes as students, interrupting instruction with questions and comments and recording their cognitive and emotional reactions to the instruction process, revealed that such an approach to providing feedback to teachers is feasible, productive, and enjoyable. (MSE)

CLIMB (Center for Learning and Instruction in Mathematics-concept Building), a model of prescriptive and instructional modes supporting practical approaches to meeting needs of adult learning, is based on premises related to learner needs, implications of mathematics education research, and relevant education for the future. These premises and…

The need of Native Americans for an improved education in mathematics is discussed, with data showing they fall below the norms in enrollment, preparation, and achievement. Contributing factors are identified and possible solutions discussed. (MNS)

How to find and classify positive integral solutions to 1/a + 1/b = 1/c in beginning and advanced algebra classes is described. The computer finds the solutions, but students practice algebraic manipulation as they analyze the solutions for patterns. Extensions to challenge more capable students are included. (MNS)

This exploratory study investigated whether Papua New Guinea university students and their western counterparts perceive lecturers similarly. Survey forms listed performance facets judged important by American and Australian students. Papua New Guinea students differed primarily because they did not distinguish between the organizational quality…

Included in this section are activities on checking with magic squares, general equations for a reflection in a line, little-known facts about the quadratic function, discovery involving volume, and conic sections. (MNS)

Presented are abstracts of 10 papers presented at the 1984 National Educational Computing Conference. Paper topics deal with science teaching using microcomputers, exploring mathematical concepts with LOGO, a chemistry problem-solving program, interactive computer graphics in mathematics, an educational game to teach science/mathematics, learning…

A two-week summer computer camp for teachers in grades one through seven is described. Examples of programing in Logo are included, as well as an overview of the curriculum, materials, evaluation, and recommendations. (MNS)
