The purposes of this study were to investigate students' conceptual learning outcomes and the effect of motivation on students' conceptual learning outcomes in two different contexts: a Web-based and a classroom-based instruction, which incorporated the Dual Situation Learning Model (DSLM). Nine classes of Grade eight students (N = 190) were…

Learning science includes learning to argue with "inscriptions": images used to symbolize information persuasively. This study examined sixth-graders learning to invest inscriptions with representational status, in a geographic information system (GIS)-based science investigation. Learning to reason with inscriptions was studied in emergent…

This paper describes the ASK-IT/Assessing-to-Learn (A2L) project which is an attempt to bring a strategic approach to learning, instruction, and communication. ASK-IT/A2L seeks to integrate formative assessment and instruction in the physics classroom at both the high school and college levels. The project and the approach are the result of years…

The reviews of articles contained in this issue have been grouped into those dealing with research related to cognitive development and to instruction. In addition, seven science education researchers have provided responses to critiques of their published research. Included are: (1) an analysis of an article designed to persuade researchers to…

Discusses a study designed to understand 11th-grade students' learning during conversations with their teacher over and about a computer-based Newtonian microworld, Interactive Physics. Illustrates that students' learning was not local but persistent, in that they used appropriate canonical science talk without teacher support. (36 references)…

Examines the interaction between mode of computer assisted instruction and cognitive style on the understanding of concept relationships and mastery of factual information. Finds learners are more effective when matched to the appropriate mode of computer assisted instruction. (MVL)

This paper describes the methods and outcomes of a 12-year longitudinal study into the effects of an early intervention program, while reflecting back on changes that have occurred in approaches to research, learning and instruction since the preliminary inception stages of the study in the mid 1960s. We began the study to challenge the prevailing…

Problem solving is defined and characteristics of good problem solvers are highlighted. The cognitive processes used in problem solving are discussed. Suggestions for methods which can be used to teach problem solving are provided. Research implications from mathematics education are listed. (CW)

Evaluates the attributes of a microcomputer software package as a supplement to chemistry instruction. Reports higher scores among the students in a control group. Discovers no significant interaction between treatment and development stage. Discusses several implications for further research. Provides the General Chemistry Test and error analysis…

Described is a computer-based tool, SemNet, which can be used by good and poor students to facilitate, extend, and polish their learning skills. Emphasized are skills associated with meaningful or deep-level learning. The components, use, and theoretical background of the software are discussed. (CW)

Science and social studies have much to offer to all learners--including those with disabilities. However, instruction in these subjects has often been overlooked in the quest to better understand and improve leaning in English/language arts and mathematics. As we demonstrate in this paper, science and social studies help students attain skills,…

Describes a unit for teaching exponential change in a noncalculus physics course by having students write recursive procedures in LOGO to graphically represent linear and exponential change. Summarizes the experience of implementing the unit in a segment on radioactive decay. Modifications to the unit are suggested for teaching exponential change…

Addresses concerns related to how educational software can be designed to accommodate a constructivist approach to learning. Describes features of software which are consistent with a constructivist view and cites examples of physics materials which are appropriate. (ML)

This book reviews the literature on effective science teaching, examining research from the United Kingdom and other countries. The studies included were those that made comparisons between two or more groups differing in science education experiences; those that involved upper elementary or lower secondary students; those that made comparisons in…

Responds to a recent critical report on computers in childhood. Highlights include computers, children, and research; social and emotional development; types of software; motivation; social and cognitive interactions; cognitive development; creativity; language and literacy; writing and word processing; mathematics and reasoning; and science and…
