Three tests were conducted to contrast the ability of bilingual and monolingual children to label and relabel objects. The findings show that bilingual subjects were significantly better than monolingual subjects, supporting the view that preschool bilingual education stimulates children's cognitive development, and enhances their self-concept.…

The generally bleak achievement scores of deaf children are contrasted with the near normal reports of both IQ and conceptual development. (Author)

Reports research which reveals the difficulty children have in understanding (1) the real purpose of written language and (2) the abstract, technical vocabulary of language study and reading. (SW)

"A new sort of concept attainment or decoding-encoding experimental paradigm based on the model is developed and an experiment on 5-, 7-, and 9-year-olds is reported. (Author)

Explores the relations among combinatorial capacities in language, symbolic play, blockbuilding, and nonsemantic action sequences within a sample of 18- to 24-month-old children, as well as assessing the developmental level of a selected subset of concepts. (HOD)

Four kinds of understanding of mathematics are suggested: instrumental, relational, intuitive, and formal. Each type of understanding is described and illustrated. (MN)

Findings from relevant research applying Piaget's theory to mental retardation, psychosis, and autism are reviewed. Many autistic individuals show an arrest in operative functions at the sensorimotor functions. The early arrest interferes with subsequent development of higher-level conceptual, symbolic, and social skills. (Author)

The effects of different models of exploration questioning on young children's associative fluency were examined in two experiments with kindergarteners. It is concluded that asking descriptive and difference exploration questions are most facilitative of children's associative fluency. (Author/SEW)

To assess the importance of visual attributes relative to acoustic and semantic attributes in children's encoding, a 64-item recognition test was administered to first- and sixth-grade children. Recognition items were linedrawings of simple objects accompanied by aural labels. By manipulating the picture, label, and referent in various…

In a study of mathematics learning, taking a rule-oriented approach, students were taught to trade objects of type A for objects of types B and C. Children ranging from ages 7 to 9 were given rules for converting A to B and B to C and were then presented with the task of converting A to C. Of the 30, 6 succeeded. Of the 24 who failed, half were…

This paper examines sixth-grade children's thinking related to solving ratio and proportion problems before these children had received any instruction in the domain. It explores unitizing and norming, one of the processes identified by both content analyses (Behr, Harel, Post, & Lesh, 1990); Harel, Behr, Post & Lesh, 1990) and research in…
