A computer microworld called Triple Representation Model uses graphical, tabular, and algebraic representations to influence conceptions of function. A majority of students were able to cope with partial data, recognize invariants while coordinating actions among representations, and recognize invariants while creating and comparing different…

The 14 essays included in this collection are an effort to apply philosophical thinking to educational themes, in the belief that critical thought is of the first importance in the conception and organization of educational activities. The book attempts to wed an analytical style of thought to a concern with practical issues. Part I provides a…

Explores a new educational application of Piaget's theories of cognitive development: the use, as a teaching tool, of physical robots conceived as artificial organisms. Reviews educational projects using real robots. Shows that the use of intelligent systems to enlarge the view of biological reality could become an integral part of curricula in…

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…

When a computer-based tool or application is used to carry out a specific task in a learning situation--that is, it is used for learning--more effectively or efficiently one speaks of learning "with" the tool or application. When, possibly, that same tool or application is used to enhance the way a learner works and thinks, and as such has effects…

Compares expert-/novice-based problem-solving behaviors with a Geographic Information Systems program. Uses naturalistic methods to analyze problem-solving strategies for occurrence of thematic elements. Reports that experts relied on logical formulations to query the database while novices used trial-and-error methods and midlevel cognitive…

Discussed are expert systems development and teaching, the representation and processing of knowledge, knowledge representation in chemical engineering, and expert systems in chemical engineering. The seven phases of expert system development are illustrated. (CW)

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…

Presents an application of the Cognitive Flexibility Theory (CFT) approach to creating hypertext for training undergraduate students through the interactive instructional program Auntie-EMM (Electronic Mail Mentor) in the use of e-mail embedding instruction within a specific context--the Wizard of Oz story. Demonstrates the effectiveness of the…

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)

Examines the relationships between the development of proportional reasoning strategies and three cognitive variables from Pascual-Leone's and Case's neo-Piagetian theories: (1) degree of field independence; (2) M-space; and (3) short-term storage space. Describes the ability of students to transfer problem-solving schemata to new contexts as well…

This paper describes the results of a study done as part of a research program investigating the use of computer-based laboratories to support self-paced discovery learning in related to microeconomics, electricity, and light refraction. Program objectives include maximizing the laboratories' effectiveness in helping students learn content…

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…

This practicum was designed to solve a problem related to the provision of a computer training component for students enrolled in an early childhood education teacher training program. Increasing pressures on graduates of the training program to integrate computers and educational software into programs for young children as well as the students'…

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)
