Students' academic achievement scores have been found to improve with the use of graphic organizers. Unfortunately, most previous research on graphic organizers has been constrained to English speakers in secondary and higher education. This study examines the effectiveness of graphic organizers when used by fourth grade students engaged in…

Hypermedia systems allow for the access of large quantities of information in flexible and interactive ways, facilitating the user's exploration of knowledge and learning. The educational system described in this paper integrates hypermedia with knowledge-based technologies. A hypermedia component in the system allows students to browse through…

As a person learns, his problem solving ability improves and one reason for this is the increased acquisition of "macro-rules" which make problem solving more efficient. An intelligent computer assisted learning (ICAI) system is being developed which automatically acquires the useful knowledge from the domain experts; as experts give the learning…

This is an international collection of 12 papers addressing artificial intelligence (AI) and knowledge technology applications in telecommunications and network management. It covers the latest and emerging AI technologies as applied to the telecommunications field. The papers are: "The Potential for Knowledge Technology in…

Cognitive flexibility is indispensable for applying knowledge to new situations. The development of this ability depends on certain conditions such as the attainment of a deep comprehension of the subject matter and the exposure to different knowledge representations. This paper focuses on these conditions and describes a study designed to foster…

Multidimensional knowledge structures, described from a constructivist perspective and aligned with the "Mind as Rhizome" metaphor, provide support for constructivist learning strategies. This qualitative study was conducted to seek empirical support for a description of multidimensional knowledge structures, focusing on the…

Traces change in conception of gravity in a boy from kindergarten until second grade, focusing on the process by which persons restructure ideas that differ from accepted scientific understandings, and acquire scientific ideas. Provides criteria for defining an alternative conception; suggests how conditions in the initial interview may have…

Explores the promises that von Glasersfeld's constructivism holds for the reform of science and mathematics education. Argues that a powerful social epistemology is needed to serve as a referent for regenerating the culture of science education. Contains 48 references. (DDR)

Discussion of dynamic modeling focuses on the development of a new modeling tool called Model-It which provides intentionally designed scaffolding for learners, enabling them to build and test dynamic models of complex systems using object-oriented and qualitative techniques. Classroom testing with high school students is described. (Author/LRW)

Addresses the issue of quality within inquiry which uses narrative forms of representing human experience. Focuses on environmental education research. (Contains 101 references.) (DDR)

Examines some of the misconceptions about the nature of critical thinking. Focuses on the characterization of critical thinking in terms of processes or skills and the separation of critical thinking and knowledge. Offers a different conception of critical thinking. (Contains 46 references.) (DDR)

Reviews Dreyfus's writings about human cognition and artificial intelligence (AI), and explains some of the implications of his position, particularly in education. Topics include Dreyfus' critique of AI, representationlaism and expertise, technology and its role in instruction, computer-assisted instruction, and intelligent tutoring systems. (JKP)

Provides brief history of Structural Communication (SC) methodology and discusses its use for teaching eighth-grade literature. Examines strengths and weaknesses of SC in print and hypermedia formats, and discusses the computer-based implementation of this participatory method of instruction. (JKP)

Describes a theoretical framework for the analysis of conceptual change that considers conceptual knowledge as a generative cognitive tool for the creation of more specific mental representations. Argues that a task-oriented interaction between propositional structures and mental models can help learners evaluate the consistency of their…

Examines changes in the science content representations of two prospective elementary teachers during their first year in an experimental teacher preparation program. Finds that opportunities to engage in cycles of instruction guided by structured considerations for content representation contributed to improvements in the teachers' science…
