Models of conceptual and language development by Orwell, Piaget, Whorf and Sapir, Vygotsky, and Bruner are reviewed. Their implications for teaching and some individual problem-solving experiments are discussed. (CP)

Describes the use of interviews with children ranging in age from 6 to 13 to identify patterns of children's beliefs in the area of heat and temperature. Also discusses how this knowledge might be used in an instructional setting. (HM)

In two experiments, 5-, 7-, and 11-year-old children and college students were presented on each trial with a sentence followed by a probe word. The children's task was to indicate whether the probe was in the sentence or not. (MS)

Three studies used computer graphics and/or verbal questioning to examine beliefs among children and adults that vision involves input to the eyes (intromission) or emissions from the eye (extramission). Results showed decreases in extramission and increases in intromission beliefs across age. There were more extramission interpretations with…

Describes an approach to the teaching of electricity that uses box and AVOW diagrams, novel representations of the properties of the electric circuit that portray current, voltage, resistance, and power. The diagrams were developed as aids in learning, understanding, and problem solving and to promote conceptual change by challenging a number of…

Examines the effects of using a conflict map on 8th grade students' conceptual change and ideational networks about simple series electric circuits. Analyzes student interview data through a flow map method. Shows that the use of conflict maps could help students construct greater, richer, and more integrated ideational networks about electric…

Claims that mind and mental objects form a societal mental structure enabling children to assimilate the society and become co-constructing members. Cites evidence that competence to create mental objects, symbols, and meanings separated from action is the evolutionary evolved human capacity for society and culture. Vygotsky's "natural"…

Secondary geometry students were tested for van Hiele level of thinking, geometry knowledge and achievement, and proof-writing achievement. Proof-writing achievement correlated significantly with van Hiele level entering geometry knowledge and geometry achievement. The predictive validity of the van Hiele model was supported. (Author/DC)

The study of affect comprehension in 15 children with pervasive developmental disorders (ages 7-10) and normal children matched for mental age found that the disabled children were impaired on affect matching compared to the controls and were impaired on face and affect matching relative to their own performance on object matching. (Author/DB)

Comparison of results obtained for 62 normally developing preschool children on the Bracken Basic Concept Scale, the Preschool Language Scale, and the Slosson Intelligence Test revealed low to moderate correlations between the three tests. Results suggest the tests do not measure the same abilities and thus cannot be used interchangeably. (DB)

Presents six articles dealing with math and science education: "Sneaker Geometry" (Jack George), "Fairs with a Flair" (Diane McCarty), "Generating Excitement with Math Projects" (Jeffrey Kostecky and Louis Roe), "Playing with Numbers" (Diana Smith), "When Student Teachers Want to Do Hands-On Science" (Betsy Feldkamp-Price), and "Science ala Carte"…

Discusses the historical background of Bloom's Taxonomy. Asserts that the Taxonomy contains elements of sex bias. Describes Women's Ways of knowing along with a comparison of the perspectives and implications of both approaches. (CFR)

Verbal and figurative classification tasks were presented to 30 blind and 30 sighted children (ages 6 to 11). Although younger blind children were significantly less efficient on tasks, older ones reached or were close to the level of their sighted peers. Analysis illustrates how the blind children adjusted their conceptual knowledge to their…

Presents a framework within which to organize and synthesize existing knowledge about children's understanding of the mental states of imagination, pretense, and dreams. Concludes that by the age of three, children understand important fundamental aspects of the mental nature, origin, and truth-relation of fictional mental states, but that their…

Observed the reactions of 3.5-month-old infants looking at a carrot that should have but did not appear in a window after passing behind a screen. The results of this and several similar experiments indicated that 3.5-month-old infants are able to represent and reason about hidden objects. (BC)
