This document, based on mathematical research conducted by the Instituto Colombiano de Pedagogia, is the first in a series of scheduled publications designed to report recent findings to teachers and to offer new methodological guidelines in teaching math. This document suggests elementary-level learning activities for helping the students develop…

Cooperative classroom structures create more positive student attitudes and interpersonal relations. Their effect on student learning is less clear. TGT (Teams-Games-Tournament) is one cooperative-competitive classroom structure which facilitates learning mathematics and language arts. A study applying TGT to third grade reading classes is…

This is one of five volumes prepared to describe various aspects of the Del Mod System. This report attempts to compare baseline data gathered in 1970-71 to post experimental data gathered in 1975-76. Sections include analyses of achievement test scores, research conducted under the auspices of the Del Mod System, and a follow-up study of…

In 1971, a comprehensive study was made of mathematics and reading achievement in the Borough of North York, Ontario. In 1974, a replication and followup study was carried out. The purposes of the study were to replicate the 1972 study, and to obtain a measure of growth in reading and mathematics achievement between grade 3 and grade 5, over the…

In this replication of the 1972 and 1974 studies of reading and mathematics achievement in North York, Ontario, approximately 20 percent of the students at each of the proposed grade levels were included in the sampling. Again, the Metropolitan Achievement Test, the Sequential Tests of Educational Progress, and the School and College Ability Test…

This report gives details of the entire process of developing and implementing an instructional service system in mathematics and science. The procedures involved in revising and validating baseline documents, in selecting instructional and supervisory staff, in developing curriculum materials, and in running inservice teacher workshops are…

Describes several facets of small-group instruction including teacher, group, and individual behaviors and use of time. Observational data were supplemented by teacher interviews concerning student groupings. Grouping practice appeared to result from decisions teachers made primarily on the basis of three factors: the teacher, the students, and…

Reports on the progress of a project designed to establish both a research agenda for mathematics education and a conceptual framework for such an undertaking. Describes four conferences which have been organized to consider teaching problem solving, effective teaching, teaching and learning algebra, and middle school number concepts. (TW)

Three articles address different uses of computers in education. British inservice training for primary school teachers using microcomputer-based adventure software is described; fundings of two Canadian projects using computer teleconferencing are reviewed; and the use of computer-assisted instruction for primary school mathematics education is…

Describes and evaluates two projects designed to update elementary and middle school mathematics programs: (1) the revision of elementary school's mathematics and computer literacy curriculum; and (2) an inservice program to train middle school teachers how to incorporate computers, calculators, and manipulatives into the classroom.

Examined is the cultural impact--both actual and potential--of the computer on children's mathematical education. The ways in which the introduction of the computer does and will change the ambient space in which children learn mathematics is considered. (Author/PK)

Describes a sequence of activities for experimenting with scaling and includes a method for revising any turtle graphic procedure so that it can be drawn to a variety of scales. (PK)

Student talk about mathematics will improve understanding. Ways that teachers can facilitate more student talk in their classrooms are presented. (PK)

Begins with the assumption that by practicing something one often learns something else. A discussion is presented on the historical and social development of knowledge, the cognitive development of students, the role of teachers, and the meaning of learning situations. (PK)

Mandler's theory of emotion is suggested as a framework for investigating affective issues in problem solving. Several dimensions of the emotional states of problem solvers are specified. Implications of this framework for research on affective issues in problem solving are also discussed. (PK)
