Young children have been taught simple sequences of alternating shapes and colors, referred to as "patterning", for the past half century in the hope that their understanding of pre-algebra and their mathematics achievement would be improved. The evidence that such patterning instruction actually improves children's academic achievement…

Three studies examined the development of category-based induction using an induction then recognition (ITR) procedure in which participants make category-based predictions about study items and are then given a surprise recognition test that requires discrimination between old and new category members. Exposure duration for study items was either…

Children took a group test of disjunctive reasoning containing 48 inclusive and exclusive items varying in content of the premises, and affirmation or negation of the conclusion. Performance improved until seventh grade. Negative conclusions produced more correct answers. Implications were discussed in relation to cognitive developmental theory…

This study assessed the ability of fourth, fifth, and sixth graders and college students to logically include and exclude variables when making inferences about a multivariate "natural experiment" situation. (Author/SB)

Investigates logical and perceptual determinants of social-cognitive development by examining children's use of consensus information for causal attribution. Results verify the importance of perceptual processes, demonstrating that children can use consensus for person attribution earlier in development than they can for stimulus attribution.…

Assesses three sets of Piagetian exclusion operations (of varying the independent variables, of holding the independent variable constant, and tautology) and of levels of thought (concrete through formal) in 33 fifth graders, 27 sixth graders, and 31 seventh graders. (HOD)

First and second graders' understanding of transitivity for each of the relations "larger than,""smaller than,""longer than," and "shorter than" was investigated. Results showed that on only two of the eight comparisons did the order of presentation of the premises make a significant difference in students'…

A program designed to teach cognitive strategies through logical problem-solving and developed for elementary learning disabled students is presented. For each problem set, the instructional procedure involves a discovery activity, discussion, conclusion, follow-up activities, and integration. Five samples of the program's problem sets (e.g.,…

Inference tasks emphasizing the acceptance of lack of closure (ALC), memory, and hypothetico-deductive reasoning were administered to 67 males and 74 females ranging in age from 5 to 12 years. Results suggest that the relationship of ALC to age is mediated by memory development rather than by logical development. (JMB)

This study investigated the use of covariation as a principle of causal analysis in children 3-4, 6-7, and 9-11 years of age. The results indicated that children as young as 3 years were capable of using covariation information in their attributions of simple physical effects. (Author/CS)

Advocates the use of classification activities in the elementary school curriculum as a means of developing thinking skills in children. Critical preclassification skills, classification activities (including simple and multiple classification), and classification tasks and materials are discussed. (Author/RH)

Comparison of elementary grade students with (N=42) or without (N=42) learning disabilities (LD) on their logical-mathematical structures of thought found that, though both groups generated grouping relationships, children with LD tendered to generate solutions showing less coordinated structures of thought. For both groups, scores on the…

Investigated was whether reading achievement could be increased by exposure to logical and perceptual tasks as found in science process activities. (MP)

Two studies with first- and fifth-grade children in two learning tasks showed that preoperational children did not necessarily learn responses followed by a stimulus object previously instrumental in obtaining a reward, while postoperational subjects did. (Author/JMB)

Provides clarification of the Piagetian theory of the development of conservation and reviews the state of knowledge regarding the theory. It is concluded that reasonable evidence exists suggesting that conservation by identity precedes and induces the emergence of conservation by inversion and compensation. (Author/DB)
