Investigated what effects two instructional strategies (related to student use of manipulative materials) would have on second-grade students' (N=96) development of logical structures. Also examined the effects of sex on logical development. Results indicate that supplying manipulative materials alone is not adequate in promoting development of…

Reports on twelve year-old students instructed in Nuffield Project and in "traditional" classrooms. A division of the subjects into two groups based on intelligence revealed significant differences on classification ability. Interaction effects were also observed. (CP)

The extended effects of two instructional approaches, the Coordinated Basal Language Arts Approach and the Integrated Experience Approach to Communication, on pupils' language development at the second- and third-grade levels were investigated. Original subjects were 669 first graders who were pretested for readiness and intelligence. Of these,…

Report of a study, using 7 13 year-old boys and girls, which sought to determine if the growth of underlying spatial abilities are enhanced more if technical drawing activities requiring multiview spatial ability are presented before surface development activities, or vice versa. Includes implications for teaching technical drawing. (TA)

After proposing and defining the superordinate concept of "historicality," fundamental interrelationships between time, events, memory, meaning, personal knowledge, public knowledge, and the histories of science are explored. Relevant research findings that demonstrate the confluence of scholarly thought concerning historicality across…

The paper provides an analysis and synthesis of studies with hearing impaired and other populations concerning the cognitive development of the principle of liquid horizontality--the idea that still water remains invariantly level regardless of the angle of the container. Three major questions focused the investigation: (1) What are the effects of…

Sociological theory and method have been used to develop a theory of complex instruction (CI). CI enables teachers to teach at a high intellectual level while reaching a wide range of students. Teachers work to create equal-status interaction within small groups as students use each other as resources to complete challenging group tasks. The…

Examining the effects of sociodramatic play and sex differences on mathematical learning and adult-observed playfulness in young children, several preliminary analyses were run of pre-test scores. Tests used were the Kindergarten Keys Mathematics Test and the Lieberman Playfulness Scale. The results of three 2(treatment) x 2(sex) analyses of…

This paper describes a cognitive and socio-moral developmental, learning style, and attitudinal study. The subjects were 168 college students enrolled in a general education "diversity core" undergraduate course on social diversity and social justice in the spring of 1990 at a large northeastern public research university. Ninety-seven students…

Reports on a study of 120 (60 boys, 60 girls) middle school students in Bophuthatswana on the relation of academic achievement to self-concept and locus of control. Finds that measures of extraversion, neuroticism, and psychoticism are related negatively to school achievement. (CFR)

The present study was designed to explore the possibility that exposure to the "Misterogers' Neighborhood" program might increase the likelihood of spontaneous imaginative play in preschool children who watched the program over a period of two weeks. The specific focus of this investigation was to determine whether a well-produced…

Effect of science instruction on young children's (N=64) concept of Piagetian physical causality was investigated. Results indicate, that pre/concrete-operational children can learn and apply a definition of living when that definition is taught through observable characteristics. Additional results and implications for elementary science…

Investigated were gender-related differences in the relationship between the development of formal reasoning skills and learning interests during the early adolescent stage. Results indicated that adolescent boys appeared to develop patterns of formal reasoning before their female classmates. Differences in subject preferences were also found. (CW)

Examines the impact of friendship on the process and outcome of peer-tutoring in a study involving 90 Welsh 8- to 9-year-old children. Finds peer-tutors have difficulty coordinating the demands of tutoring tasks because of their limited cognitive resources. Also finds friendship imposes greater burdens on children's limited resources. (NL)
