Factor analysis accounts for most of the variance in adult ratings of concepts with adjectives. Affective reactions are present in young infants, but still to be explored is how the stable adult factor structure develops from these reactions. Three questions are investigated in this study: (1) is this factor structure present in 3- and…

The effects of observing a model and of providing a response rule on the learning, transfer, and retention of a dial-reading, numerical concept were studied in 144 third-graders. Different experimenters conducted the immediate learning procedures versus the measurements of retention. No extrinsic reinforcers were promised or dispensed. The…

A semantic-relatedness test and a cloze-type/sentence-completion test compared meanings ascribed to spatial prepositions by adult native English and advanced English-as-a-second-language speakers. Non-native speakers differed from native speakers in the semantic boundaries ascribed to the words, with the differences deriving from weighting…

The development of the concept of word is discussed in terms of specific advantages that might be available to bilingual children when compared with their monolingual peers. Three studies are reviewed in which bilingual children show more advanced understanding of some aspects of the concept of word than do monolingual children (Author/LMO)

Presents perspectives on creating new technology-based supports for science learning. Reviews current philosophies concerning the interpretative nature of scientific inquiry and discusses the difficulties of students and teachers in science education. Describes a prototype software system for supporting scientific inquiry processes in students.…

Critiques five arguments cited in support of process science. Considers the problematic nature of the processes and consequent difficulties encountered in mirroring these processes. Suggests an alternative way of viewing physics education through a trio of types of knowledge which can be used as governing principles in shaping education. (RT)

Reports on a study designed to investigate aspects of young children's knowledge of fractions and partitions of quantities. Findings suggest that although children did not have a deep understanding of the concept of one half, a significant number demonstrated a powerful systematic procedure leading to the creation of accurate equal fractional…

Defines cognitive computer tools as software programs that use the control capabilities of computers to amplify, extend, or enhance human cognition; suggests seven ways in which computers can aid learning; and describes the "Learning Tool," a software package for the Apple Macintosh microcomputer that is designed to aid learning of…

Describes a study which sought to determine whether differences existed between girls and boys in terms of their concept structure interrelatedness competence (ConSIC) in the areas of physical science, life science, earth sciences, between sciences, within sciences and across all sciences by measuring ConSIC. (ML)

Tested Ausubel/Novak hypothesis that primary grade students can learn meaningfully certain aspects of science concepts in the "reception learning" model. Revised audio-tutorial instruction unit on earth based on understanding children's misconceptions; assessed impact of revised units with second graders; and compared results to concept…

A set of immediate memory-span tests, concept- and rule-learning tasks, and an IQ test were administered to adolescents. A color-form memory factor and IQ substantially predicted rule-learning proficiency. Effects of memory aids appeared to induce conceptual rules and serve as a base for rehearsing information. (Author/RD)

Reports three experiments to test age-related difFerences in sentence memory arising from sources other than noncognitive factors. Age-related differences are discussed in terms of deficiencies at encoding and retrieval. (PMJ)

Four studies examined preschoolers' use of the cue of action initiation to infer another's desired goal. Found that differences in action initiation play an increasingly important role in 3-year-olds' mentalistic explanations of action, and that this development may be related to other critical changes occurring in their developing theory of mind.…

Compared and contrasted are the concepts intuition and logic. The ideas of conceptual thought and algorithmic thought are discussed in terms of the world as a labyrinth, intuition and time, and the structure of knowledge. (KR)

Discussed is the effectiveness of using analogies in chemistry instruction. Students' mathematics anxiety, spatial visualization skill, and proportional reasoning ability were found to be important aptitudes for determining chemistry achievement. The relationship between analogs and algorithms is described. (KR)
