Three elements relating to reading in mathematics are discussed: language and mathematics, readability and mathematics materials, and suggestions for improvement of reading in mathematics. (MP)

Reported is a study involving six group administered tasks concerning proportional, probablistic, and correlational reasoning with 505 students aged 11.5 to 20.0 years. Investigated were the effectiveness of the tasks for assessing formal reasoning; categories of classification for students' responses and implications for teaching are suggested by…

The shaping of human motor development is demonstrated by the orderly sequence of events which occur throughout the individual's development process. Muscular strength and proficiency in gross motor skills improve with advancing chronological age throughout childhood and adolescence, with sex differences in performance tending to favor males.

A case study of a six-year-old reveals that unfounded assumptions about language growth and development may debilitate rather than facilitate the process of language literacy. Recommendations are made for open-entry language activities where constraints are allowed to evolve in a risk free language environment. (JN)

Both right-and left-handed normally developing 6-year-olds showed considerable evidence of bilateralization of hemispheric functions for spatial and verbal information processing; the slowly developing children (ages 5-9) exhibited unusual patterns of hemispheric specialization usually opposite those typically expected in children or adults.…

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)
