Compared is an inquiry-oriented Biological Sciences Curriculum Study (BSCS) style laboratory approach with a more directive traditional approach on student outcomes in the cognitive and affective domains of learning. Differences in science achievement, reasoning ability, attitude, and stages of development are discussed. (KR)

Thirty-four children (ages 5-16) born to alcoholic mothers were assessed on measures of intelligence, reading, receptive vocabulary, memory for sentences, visual memory, and visual-motor integration. The children were found to be least deficient on intellectual measures and most deficient on memory for sentences and silent and oral readings.…

The postgraduate Teacher Thinking Seminar (TTS) was created to explore the implications of constructivist theory for teachers' education and development. Using participants' own practical knowledge, the main strategy was the dialectical process of group reflection. The article elaborates four seminar examples, suggesting that TTS can effectively…

This research assessed Australian high school students' understanding of light, developed materials to conceptual change with respect to the concept, and evaluated the effectiveness of teaching strategies utilizing the materials. After instruction, students were able to construct significantly more scientifically acceptable answers. An appendix…

Reports on a study of learning achievement in economics among five groups of third-grade students using the videotape instructional program, "Econ and Me." Finds that, although students achieved some level of content mastery, the overall results were not as dramatic as had been expected. Calls for further research into transfer of…

Critiques the attempt by David Pariser and Axel van den Berg to apply the author's methods to a cross-cultural study. Argues that their study is too flawed to be definitive. Suggests means to test the universality of the U-curve as a cognitive development pattern or an artifact of culturally defined aesthetics. (DSK)

Responds to a critique of the authors' work by Jessica Davis. Enumerates and responds to each of Davis' critiques, arguing that many of them are invalid. Defends the research design choices made by the authors and the results of their study. (DSK)

Describes a Differentiated Education Program (DEP) for gifted children in inclusive settings in New Zealand, identifies two differentiated curriculum models, and provides implementation strategies and evaluation pointers. The need for a DEP to provide opportunities to develop thinking skills, creativity, and emotional and social skills are…

Examines perceptions concerning the shape of the earth and the causes of the day/night cycle among American Indian children. Interviews with 26 Lakota/Dakota elementary children revealed a preference for a synthetic model of the earth and animistic explanations for the day/night cycle. Includes excerpts from the interviews. (MJP)

Reports on an experiment that explored novice learners' responses to anomalous data (new data that contradict previous beliefs). Secondary education students were given both anomalous and confirmatory data concerning various theories about the origin of life on earth. Statistical data reveal their level of awareness of the contradictions. (MJP)

Examines the reading attainment levels of a group of elementary students who had either experienced nursery, day care, or no preschool provision outside the home. Compares pupils' scores on reading tests over four years. Although the results were inconclusive they suggest positive reading attainment outcomes related to preschool experience. (MJP)

Presents a developmental framework for the study of culture and cognition in which cultural practice is a key organizing construct. Argues that systematic analysis of either cultural change or cognitive development requires that they be understood relative to one another in a single integrative treatment. (Author/SD)

Examined the relationship of environmental input to cognitive growth in language, spatial operations, concepts, and associative memory in children tested four times six months apart and differing in the amount of school input received. Found that children made greater growth over periods with greater amounts of school input for language, spatial…

Reviews selected research on children's early formation of categories. Finds sophistication in how children group objects and think about those groupings. Notes findings related to type of grouping (thematic or taxonomic), multiple classifications, overgeneralization, the role of background knowledge on classification abilities, the…

A study of 114 children examined the relationship of children's competence with objects and peers during free play with stimulating, involved teacher behavior; activity setting; as well as teacher and peer presence. Results are discussed in light of current research and theory on classroom practices designed to enhance children's development. (TJQ)
