Implications of using authentic activity as a model for appropriate learning activity are discussed, particularly in regard to the design of computer-based simulations and project-based learning activities. Mere provision of computer-based simulations and reality-centered projects does not ensure that a student will derive the benefits of…

This guide lists 19 software packages considered to be worthy of further consideration by other reviewing agencies and schools by a group of 17 computer coordinators from educational software preview centers and evaluation agencies. The following software is listed: (1) ASK-IT, an authoring tool; (2) Balance of the Planet, an environmental…

Four field tests of Canadian software show that computerized interactive fiction teaches both history and independent reading/study skills. (ARH)

This paper reports upon an active learning approach that promotes conceptual change when studying direct current electricity circuits, using free open source software, "Qucs". The study involved a total of 102 prospective mathematics teacher students. Prior to instruction, students' understanding of direct current electricity was…

The use of numerical simulations to design and analyze new products requires both conceptual and operational knowledge. This paper describes COMPANION: an intelligent multimedia system for vocational training used by engineers and technicians. A key concept in terms of training methodology is that of "situated learning," or continuous…

A previous simulation study of methods for assessing item functioning (DIF) in computer-adaptive tests (CATs) showed that modified versions of the Mantel-Haenszel and standardization methods work well with CAT data. In that study, data were generated using the three-parameter logistic (3PL) model, and this same model was assumed in obtaining item…

Related to the earlier ACT production system theory, this book's basic goal is to present evidence for the psychological reality of a production system model of mind. Distinguished from the original theory in three ways, this volume uses previous rational analyses to improve upon that theory and extend its scope. It also relates the theory to new…

To function effectively as a learning environment, a simulation system must present learners with situations in which they use relevant knowledge, skills, and abilities. To function effectively as an assessment, such a system must additionally be able to evoke and interpret observable evidence about targeted knowledge in a manner that is…

This report reflects research and development on visualization and the use of multimedia carried out at the Department of Applied Education, Division of Instrumental Science and Technology of the University of Twente (Netherlands) and the Andersen Consulting Educational Computing Consortium, also at the University of Twente. The report contains 11…

Mathematics problem solving skills need to be developed through meaningful interactions. Computer simulations combined with cooperative learning methods provide students a context within which to construct an understanding of mathematics problem solving. This study examines the distribution and sequence of events that result in acquisition of…

Since their introduction into schools, educators have tried to utilize computers in classes in order to make difficult topics more comprehensible. Chemistry educators, when faced with the task of teaching a topic that cannot be taught through experiments in a laboratory, resort to computers to help students visualize difficult concepts and…

Interactive videodisc (IVD) offers a combination of media with practical applications in vocational education. IVD is superior to videotapes and other media in quality, applicability, and effectiveness. IVD can be used in different settings and for a variety of instructional applications. Although not appropriate for every learning situation, IVD…

A nominal response model-based computerized adaptive testing procedure (nominal CAT) was implemented using simulated data. Ability estimates from the nominal CAT were compared to those from a CAT based upon the three-parameter logistic model (3PL CAT). Furthermore, estimates from both CAT procedures were compared with the known true abilities used…

Achieving enrollment goals continues to be a major administrative concern in higher education. Enrollment management can be assisted through the use of computerized planning and forecast models. Although commercially available Markov transition type curve fitting models have been developed and used, a microcomputer-based decision planning model…

With the help of widely available microcomputers, it is possible to demonstrate certain statistical phenomena which students of statistics are usually expected to take on faith. Two demonstrations are described. In the first demonstration, three common types of sampling (simple random, biased, and stratified-random) are used to compare statistics…
