The need for students of engineering to acquire the rational, methodical approaches identified with the "mathematical way of thinking" is discussed. The skill areas in mathematics most critical to engineering majors are pointed out, with proper shaping of student attitudes seen as an important role secondary school mathematics must play.…

The results suggest that cognitive training specifically designed to promote generalization to classroom tasks can improve the classroom behavior and academic achievement of hyperactive children. (Author)

Five basic skill areas needing more attention in standard high school geometry are discussed. Levels of student mental development in geometry and a need for less emphasis on formal proofs are reviewed. (MP)

The development of formal operations in normal adolescents is briefly examined, and a discussion of the development of exceptional adolescents focuses on the following exceptionalities: retardation, blindness, deafness, and giftedness. Some directions for future research are considered. (DLS)

This discussion centers around the dangers in making too precise a particular concept in educational psychology that distinguishes between two types of understanding, instrumental and relational. (MP)

Comments on the study reported by Lawson, Karplus, and Adi (1978) which indicated that formal schemata and propositional logic are not part of the same structured unity of mental operations proposed by Piaget. (HM)

Piaget's formal operational stage is related to the teaching of science by focusing on the development of paper and pencil tests for determining students' cognitive level of development and on procedures for helping concrete operational students improve achievement and become more formal in their thinking. (JMF)

States that teachers should understand how they can legitimately use play to accomplish teaching-learning objectives, suggests a model for formulating a play ethic for teacher training, and presents a play matrix showing the areas of impact in play theory for the teaching-learning process. (MF)

Examines the development of social relations in kindergarten, first-, second-, and third-grade children through an assessment of the children's role-taking skills and classification abilities. (CM)

Raven's Progressive Matrices test items were analyzed for M demand (Pascual-Leone's developmental construct). Data on second- and third-grade subjects were analyzed for extent of absolute agreement of Raven and Figural Intersection Test (FIT) scores. Raw scores on the Raven could be deduced on the basis of FIT performance. (Author/RD)

Students were administered either conditional syllogism, biconditional syllogism, or conditional and biconditional syllogism tests. Analyses confirmed a tendency towards biconditionality. With conditional syllogisms, results indicated variations across forms of both major and second premises and a reversed developmental trend on problems which…

The purposes of this paper are to explore the major reasons for limited contraception practices for improving sex education. Three areas are identified for discussion: lack of information, cognitive-emotional development, and acceptance of sexuality. (Author)

The influence of televised modeling and modeling plus direct instruction was examined on the induction of complex forms of seriation behavior. The television only and TV plus direct instruction groups made significant gains from pre- to post-test, which were maintained during retention testing. Theoretical and training implications were…

Children's ability to produce and use natural language mediators on a paired-associate recall task requiring self-generated elaboration was analyzed. Elaborations were recorded and classified according to a semantic-syntactic scheme. Comparisons between grades were made to determine the effectiveness of elaboration categories in facilitating…
