The author attacks not only the racism inherent in existing IQ tests, but the very concept of a standardized intelligence test, which, he asserts, lacks certain basic criteria of consistency and validity necessary to a scientific device. Part of a theme issue on intelligence. (SJL)

Intended as a nontechnical review of current scientific knowledge in the field, this essay considers the nature of primary and secondary intellectual abilities, plus the major features of, and the development of individual differences in, the skills and capacities constituting intelligence. Part of a theme issue on intelligence. (Author/SJL)

The author presents intelligence and learning as theoretically and empirically separate concepts. Examining Spearman's "g" factor and the evolution, phylogeny and psychometrics of intelligence, he concludes that "g" is of dominant importance in scholastic learning. He notes some implications for equal educational opportunity. Within a theme issue…

This paper is intended to aid interpretation of intelligence tests in light of neurological findings and to suggest future test designs which would reflect cerebral hemisphere specialization. The need is emphasized for improved measures of right brain functioning, especially for Blacks, who exhibit some degree of right hemisphere preference. (SJL)

A computer scan of ACT Assessment records identified 3,427 sets of twins. The Hardy-Weinberg rule was used to estimate the proportion of monozygotic twins in the sample. Matrices of genetic and environmental influences were produced. The heaviest loadings were clearly in the genetic matrix. (SJL)

The authors review studies on the effects of these three types of learning situations on students' motivation, self-concept, attitudes, and psychological health. While concluding that all three can be appropriately used in the classroom, they give particular attention to the teacher's role in implementing cooperative activities. (SJL)

The jigsaw technique of classroom instruction utilizes small groups and peer teaching to help students develop the skill of cooperation. The authors review research on its effect on achievement, role taking abilities, and interethnic perceptions in Mexican American and Anglo students. Implications for desegregation are drawn. (SJL)

Teams-Games-Tournaments (TGT) is a classroom program which addresses the problems of student values, student diversity, and basic skills. This article describes: how TGT works, its origins, research to date, implications for teachers and researchers, how TGT is used in the classroom, and new directions for TGT. (Author/SJL)

This paper begins with a discussion of a theory of teams in general and then proceeds to a description of a program of research focused on a simple but carefully structured classroom team technique, Student Teams-Achievement Divisions, or STAD. (Author)

This paper reviews experiments conducted at CEMREL in St. Louis, on individual and group reinforcement for tutoring. It summarizes results on how reward structures relate to effective student cooperation and how rewards interact with other variables such as subject area, classroom size, and age. Further research issues are proposed. (SJL)

The research described in this report elaborates the dimensions and effects on elementary-aged children of cooperative, competitive, and individualized learning environments, with specific focus on peer relationships and personal satisfactions and dissatisfactions. Children's behavior was observed within the learning environments and again…

Studies involving puzzle-solving in competitive, cooperative, and individual settings demonstrate that children's reactions to their own and other's success and failure are strongly influenced by the reward contingencies offered. Reward structures have different implications for children differing in self-concept level. Implications for the…

Studies with the Madsen Cooperation Board are described, showing differences in cooperation and competition between Polynesian and European children. Another study of Cook Islands, Samoan, and Fijian children is reported and the school's role in increasing competitive behavior discussed. Teaching changes are suggested to encourage more adaptive…

Laboratory and field tests were made of the contact hypothesis that individuals from hostile groups will show favorable attitude changes after working together in an interdependent and equalitarian situation. Groups studied included female college students, disadvantaged mothers, airmen, and teachers in newly desegregated schools. (SJL)

College students, ranked as high, medium, or low ability, were assigned to homogeneous or mixed-ability groups of two through five members for a test. Performance proved proportional to the number of high ability group members. The underlying group process was inferred through social decision scheme analysis. (Author/SJL)
