Effects of a measurement and planning system on the cognitive development, promotion, and referral to special education of 838 public school kindergartners were studied. The 428-member experimental group, whose 29 teachers implemented the system, had higher posttest scores in reading, mathematics, and science than did the 410-member control group.…

A study interviewed 6 grade-6 students after participation in 21 lessons on basic concepts of fractions and decimals to determine how different children construct rational number concepts. Discussed the formation of the key concept of equivalent fractions based on student responses to interview questions. (MDH)

Discusses the two overgeneralizations "multiplications makes bigger" and "division makes smaller" in the context of solving word problems involving rational numbers less than one. Presents activities to help students make sense of multiplication and division in these situations. (MDH)

Reviews research on (1) schemata acquisition while learning mathematics and techniques for detecting schema in mathematics learners; and (2) assessment of the distribution of cognitive resources while learning mathematics that lead to the design of instructional techniques to facilitate schema acquisition. (26 references) (MDH)

Describes seven number-sense skills for elementary and middle school grades. Provides eight short stories for grades three through eight designed to develop students' number-sense skills in which students replace missing data so that the story makes sense. (MDH)

Children at risk for cognitive difficulties were put in two intervention groups, family and day care education and family education alone, and one control group. Children were tested for cognitive performance. The family and day care group scored higher than other groups. No intervention effects were observed for the family education alone group.…

Describes study that examined kindergarten and second grade students' recall of information that had been presented on a computer with varying levels of visual action and verbal labels. Developmental differences in children's use of verbal and visual systems are discussed, and reading ability levels are considered. (29 references) (LRW)

Used 2 12-year-old children to investigate deductive and inductive reasoning in plane geometry. A LOGO microworld was programmed to measure distances and turns relative to points on the plane. Learning environments like this may enhance formation of inductive geometrical understandings. (Contains 44 references.) (LDR)

Investigated primary school children's scientific understanding and the conceptual change that occurs when using an interactive approach to teaching science. Discourse analysis of classroom conversations indicated three different types of teacher-child and child-child interactions. (Contains 53 references.) (MDH)

Five experiments examined children's use of eye gaze information for inferring another person's desire. Found that 4-year olds used another's eye direction to infer desires, while 3-year olds could use other nonverbal cues. Two- and 3-year olds used eye gaze for desire inference when presented dynamically with other scaffolding cues. When…

Identifies two frameworks that limit teachers' vision: (1) a transmission perspective on learning; and (2) a limiting conception of and anxious approach to technology. This study helped teachers break free of these restraints by providing an opportunity to become learners in a technological context based on developmentalist views of teaching and…

This study of 16 Singapore child care centers found that children spent most of their time engaged in adult-led group, cognitive, and daily routine activities. Findings also suggest that good quality centers offer a variety of cognitively stimulating activities, such as literacy activities, academic and problem-solving tasks, and verbal…

Examines the generalizability of claims about the implicit learning of artificial grammars to the context of adult second-language acquisition (SLA). Specifically addressed are claims that implicit learning is more effective than explicit learning when the stimulus domain is complex, and explicit learning of simple and complex stimulus domains is…

Investigated development of ability to recognize, anticipate, and plan the replay of recorded action sequences. Effects of an educational intervention on this ability were evaluated for two- to five-year olds. Results suggest that representational competence is a teachable concept and that a complex mediating structure allows children to…

Comments on the articles presented in this issue, discussing factors that influence the climate for learning. Ways that beliefs, past experiences, and cultural competence of adults may influence their ability to work collaboratively and support children's collaborative work are discussed, as are the effects of various adult interaction styles on…
