The use of calculators in helping students to construct their own learning is discussed. Two games which illustrate this concept are presented. The features of a constructivist lesson which uses calculators are listed. (CW)

Twenty-seven toddlers identified as showing specific expressive language delay (ELD) were studied and followed through the preschool period. Findings indicated that home-based intervention accelerated vocabulary skills, but did not decrease the likelihood of later phonological problems. ELD was also seen as a self-correcting condition.

Longitudinal and cross-sectional studies of young English-, French-, and Korean-speaking children showed that, across the three languages, children go through three similar developmental stages before they acquire the adult system of answering negative questions. Several language-specific phenomena were observed. (BC)

Compared 16 fourth- and fifth-grade boys who participated in Discovery, developmental program in which students with history of inappropriate classroom behaviors acted as peer tutors for kindergarten students, to 16 control participants. Found no significant increase in moral development among Discovery participants but did find significant…

Psychometric information was obtained on the Longeot test, which measures aspects of formal thinking, from a sample of 884 high school science students in India taking a Hindi version of the test. The test version appears valid for these students and may be used to classify subjects into Piagetian developmental levels. (SLD)

Responses of students in grades K-10 (42 interviewed; 98 written) to 4 common fractions problems were analyzed for iconic mode processes in relationship to concrete symbolic mode development. Concludes that progress in the latter, without development of complementary iconic support, limits both understanding and flexibility in solving problems.…

This paper is concerned with pupils' learning of the concept of variable in the LOGO programing environment and how this relates to teaching. Results from three research projects are described and compared in a discussion of how improvements in learning have been influenced by a refinement in teaching method. (Contains 21 references.)

Contends that instruction at the primary school level should be consistent with the child's development and experiences. Describes how geography's "Five Themes" can be taught using an interdisciplinary approach. Includes three lesson plans divided among concrete, semiconcrete, and abstract levels of cognitive development. (CFR)

Reviews the rationale and evolution of the Writing across the Curriculum (WAC) movement and applies it to college level sociology courses.

A study examined the effects of differing degrees of bilingualism (English monolingual, English-French balanced bilingual, Bengali-English partial bilingual) on nonverbal problem-solving abilities of 71 grade-three children. The groups were compared on control of attention and analysis of knowledge. Results indicate the balanced bilinguals…

Describes two studies that assessed decision-making skills using common cognitive errors and evaluated the impact of computer-based role-playing exercises on the development of these skills. Results with high school students, undergraduates, and earth science professionals are discussed which indicate that well-designed computer-based laboratories…

Two studies compared children's knowledge about the letters in their name with knowledge of other letters. Findings indicated that Australian first graders and U.S. kindergartners and preschoolers had superior knowledge of letter-name, but not letter-sound, for first letter of their first name. Also, U.S. preschoolers were better at printing the…

Replicates Jessica Davis' study of the U-shaped aesthetic development curve in a cross-cultural setting. Examines whether a similar U-curve is evidenced in Chinese aesthetic development. Presents results that suggest that Chinese aesthetic criteria do not produce a U-shaped evaluation of artistic skills. Discusses limitations of the study. (DSK)

Examines the educational potential for intelligent agents as cognitive tools. Discusses the role of intelligent agents: managing large amounts of information (information overload), serving as a pedagogical expert, and creating programming environments for the learner. (AEF)

Reports on an investigation of young children's (n=15) spontaneously constructed or naive understanding of the particulate nature of matter to any formal instruction in the domain. Speculates that children first develop local frameworks particular to different classes of substances, then slowly expand those frameworks to include a wide range of…
