Examines operations of generalization, identification, discrimination, and synthesis in mathematical concept development from early childhood to late adolescence according to Vygotsky's theory of development. (MDH)

The "componential" theory of intelligence explains intelligence in terms of three types of component processes that make up intelligent performance. The first of these, "metacomponents," are the higher-order or executive processes that one uses to plan what one is going to do, monitor what one is doing, and evaluate what one…

A study investigated the reason for the high performance of bilingual children on a syllogistic reasoning task. Thirty-nine Puerto Rican Spanish-English bilingual children in grades 3 through 6 were asked to solve problems in both languages. Response times were recorded, and the subjects were asked to justify their answers to assess to what extent…

This paper attempts to fill some of the gaps in the literature (on reflective teaching), delving further into the meaning and functions of reflection. First, it considers the origins of the term and some aspects of its development. It then analyzes and critiques some of the current notions of reflection. Beginning the process of a more rigorous…

A model for the development of scientific reasoning in adolescents was formulated largely upon the basis of Piagetian theory. Included as potential determinants of scientific reasoning were: experience; age; locus of control; field dependence-independence (FID); rigidity/flexibility; intelligence quotient (IQ); and sex. Causal relationships…

In the first section a sketch of a tense logic is presented and a mechanism is suggested for including aspects of the tense logic into the Grammar (theory of language). Specifically, several grammatical structures are shown to incorporate temporal features. A semantic projection mechanism is utilized to amalgamate the temporal features in elements…

Examines content and problem effects of formal thought in 13-year-olds (N=120). Three controlling variables tasks with different content and two question-type tests (analysis and controlling questions) were administered. Findings, among others, indicate that content and problem effects contribute to variance on formal reasoning problems.…

Defines a generalization as "a descriptive statement of broad application indicating a relationship between two or more concepts." Argues that successful teaching about generalizations can only occur when students understand the relationship between concepts and facts. Discusses four issues and four approaches related to teaching…

Reviews a monograph which addresses children's higher-order thinking skills. Suggests the following for teaching problem solving: identify and develop content-independent and content-dependent problem-solving skills, connect developed skills through workshop-style activities to subject discipline, and help students identify and reconstruct their…

Discusses a variation on tiling that offers opportunities for the construction of the fundamental mathematical concept of constructing abstract units called "unitizing." Tiling integrates geometric and numerical settings to develop spatial sense and present mathematics as constructing patterns. (MDH)

This study was designed to examine the effect of different kinds of adult mediation on the cognitive performance of young children who used computers. The study sample included 150 kindergarten children aged 5-6. The findings indicate that children who engaged in adult-mediated computer activity improved the level of their cognitive performance on…

Noting evidence of continuity and progression in young children' thinking, this book explores the promotion of high-quality thinking and action in children ages 3 to 5 years. Some thoughts about children from birth to 3 years and from 5 to 8 years of age are also included as part of the discussion of continuity in teaching and learning. Throughout…

The academic standings of provisionally admitted high school graduates and matched controls (regular admissions) at a state university were analyzed after one to three years. The results revealed highly significant differences in favor of the controls. The criterion was academic status at the university. Analysis of covariance controlling the…

Three sections of the Graduate Record Examinations (GRE) Aptitude Test were reviewed before the introduction of the restructured test in October, 1977: research on (1) the GRE-Verbal section; (2) the GRE-Quantitative section; and (3) a planned third section, measuring analytical thinking skills. Research in all three areas focused on test…

A series of five experiments was designed and administered to 679 elementary and junior high school students over a 2-year period to test the relevance of Jean Piaget's concept of conservation to musical learning. Musical tasks consisting of stimulus patterns and systematic variations of these patterns were designed for each experiment, and…
