Describes the design, construction, and use of oversize lecture-demonstration atomic/molecular models. These models appeal to both concrete and formal operational students. Also describes construction and use of an "spdf" sandwich board and an experiment using attribute blocks. (JN)

Redefines intelligence as a useful, comprehensive, and flexible construct that allows its modifiability as a function of age and culture. Reviews theories on two-factor, multiple-factor, facet, and hierarchical models of trait formation based on research in developmental, cross-cultural, learning, and cognitive psychology. (Author/AOS)

Proposes five generalizations on existing knowledge, learning, and their interaction, and discusses evidence for these from recent research on children's learning, memory, conceptual understanding, and problem solving. (Author/AOS)

Presents the findings of a recent study on the writing and reading achievement of low SES children. Concludes that there is a need for more emphasis on writing for these children. (JL)

Examined effects of operational levels of ninth-grade (N=16) and college (N=40) students on causal explanations they recalled after instruction. Results indicate concrete/formal students recalled explanations requiring chaining of two implication statements while formal subjects outperformed concrete subjects in reconstruction of complex…

Used paired comparison to construct a reading preference inventory based on 14 reading themes drawn from previous research. Tested it using intermediate-grade children in three Canadian communities. (FL)

Using Tough's hierarchical analysis of language functions, this study found developmental differences in the communicative functions and strategies used by preschoolers in their conversations with one another. Generally found that females developed language strategies earlier than males and achieved a more advanced level of cognitive complexity…

Discusses the concept of egocentrism and its relation to cognitive development. Describes the major stages of egocentrism: sensori-motor, preoperational, concrete operational, and adolescent egocentrism. Focuses on research support for the theory of adolescent egocentrism. Discusses educational implications. (RC)

Investigated cognitive development of eleventh-grade students (N=389) in Jordan and its relationship to comprehension of concrete and formal physics concepts. Results revealed that cognitive level (17% formal; 52% concrete) was related to comprehension of both concrete and formal concepts. Findings related to sex differences are also reported.…

Describes a set of Science Reasoning Tasks which are valid and reliable for assessing the ability of children to use concrete and formal reasoning strategies and can be used by science teachers without professional training in Piagetian studies. Thirty pupils can be tested on each task in about 50 minutes. (Author/DS)

Curriculum theory is a rationale for defining purpose, selecting objectives, and determining content. Two rationales, movement analysis, and developmental stages are discussed and evaluated, in terms of their purposes, objectives, content, and teaching methods. (JN)

Assessed the effect of a one-semester college biology course on the development of students (N=72) ability to reason formally and interactions among intelligence, cognitive style, and cognitive level. Includes implications for science instruction. (SK)

Six studies investigated the use of pictorial material in a group setting to measure the cognitive level of children (age 7 to 11) on eight Piagetian concepts. Children were low to middle socioeconomic status with 60 percent Spanish surnames. Factor analysis and clinical administration supported test validity. (Author/CTM)

A study of the development of high school students' self-social relationships indicated a need for a concentrated program on personal growth and development in tenth grade when individual identities are forming. High school students scored highest on the self-complexity and self-centrality tests. Developmental trends for sex were also indicated.…

A study of adult learners reveals four steps of transformative change in adult life: diffusion, dissonance, differentiation, and coherence. The educational implications of these steps are explored through case studies, and it is argued that these transformative changes affect not only the individual and the nature of adult education, but the…
