The Triple Representation Model of problem solving is presented. The use of microcomputers in this problem-solving environment is discussed, and examples are provided. The integration of this method into the mathematics curriculum is described. (CW)

Presented are several simple kinetic systems together with the spreadsheets used to solve them. A set of exercises in chemical kinetics appropriate for an introductory course in physical chemistry is given. Error propagation calculations with experimental data are illustrated. (CW)

Described is a short program for teaching and learning about geometric transformations. The integration of geometry problem solving and BASIC programing is discussed. Applications of computer graphics are illustrated. (CW)

This paper focuses on the philosophy and development of an inquiry-based, level three interactive videodisc project for promoting critical thinking. The contents of the project include life, earth/space, and physical science with three discs in each area. Two flowcharts show the choices open to students in the videodiscs. (Author/YP)

Described are two applications of computers in chemistry. The multilinear equations and procedures used in obtaining a least-squares solution for curve fitting in chemistry are presented. Also discussed is the program "ATORB" which can be used to generate graphs of probable electron clouds for various atoms and molecules. (CW)

This article presents a vector-analysis approach to the classical three-point problem in hydrogeology. Problem sets involving strike and dip, and ground water flow including computer programs (in BASIC) for their solution are given. (CW)

Discusses new developments in digitizing manuscripts. Introduces four categories describing level of detail for digital images in historical information systems. These are illustrative, readable, Paleographic quality, and enhanceable. Examines traditional architecture, tagged manuscripts, and approaches to full-text integration. (MJP)

Maintains that most computer tutorials retain a print orientation substituting connected computer screens for the pages of a book. Argues for a more creative use of computers' interactive capability. Presents three model tutorials concerning the Maastricht Treaty and U.S. Constitutional ratification. (MJP)

Maintains that the use of metacognitive learning strategies have been recurrent pedagogical tools for facilitating foreign language learning. Describes how new hypermedia and interactive video technology have broadened the scope of computer-assisted instruction. Calls for more research on this topic. (CFR)

Presents a study in which children considered alternative continuations of a text through a computer program. Reports that subjects were to monitor text production and correct coherence problems. Discusses reason levels: (1) implicit, local reasoning; (2) attention to global text characteristics; and (3) considerations on the function of…

ENLIST Micros, a project designed to improve quality and quantity of microcomputer use in science teaching, is described. Rationale and procedures behind its development; description of the pilot test model; results of the initial field test and an implementation study; description of the revised ENLIST Micros curriculum; and recommendations for…

Approaches to college student monitoring have been shaped by changing contexts and evolving technical capabilities, beginning with retention studies and developing into fully relational databases for cohort tracking. Institutional researchers should know this history and be aware of the specific demands for information that future tracking systems…

Design research has grown in importance since it was first conceptualized in the early 90s, but it has not been adopted for research in instructional technology in higher education to any great extent. Many researchers continue to conduct studies that principally seek to determine the effectiveness of the delivery medium, rather than the…

This encyclopedia provides scholarly information on all aspects of educational technology. It treats integrating educational technology as a problem-solving process. The book consists of 123 papers by numerous authors, divided into five sections. Section 1, "Educational Technology: Definition and Conceptual Background," introduces educational…

This handbook provides an overview of research in the field of educational communications and technology. The handbook may be used to familiarize students and researchers with a domain of research in this field prior to their own research, or may be used as a guide for selecting research topics or methodologies. The book consists of 42 papers by…
