Five papers on the use of computer simulation (CS) in educational research are presented. The impacts of CS on educational research, modeling task performance, use of CS in problem solving in subject-matter domains, an interpretation synthesis model of medical teaching rounds discourse for expert system interaction, and computer-based learning…

Describes an expert system microcomputer-based program, ZEERA, which is designed to help users understand and perform statistical analyses. Computer-assisted instruction and the traditional approach of drill and practice are discussed, and benefits of using ZEERA are described based on testing in a university elementary statistics course. (11…

Uses examples from four exercises to show how computer-based education (CBE) is used to teach problem-solving in a physiology course. Screen prints are included to illustrate the exercises. Several benefits of using CBE strategies in physiology are also considered. (JN)

Presents a predator-prey simulation which involves students in collecting data, solving problems, and making predictions on the evolution of prey populations. Provides directives on how to perform the chi-square test and also includes an Applesoft BASK program that performs the calculations. (ML)

Presents a step-wise approach to introducing computer-assisted drill into a college-level preparatory chemistry course. Describes identification of need, choice of computer system, software development, program evaluation, and future directions. (JM)

Four key areas in the design of computer-based training are transfer of training, interactivity, development of problem-solving skills, and stimulation of learner interest. (SK)

Provides examples of senior management development courses that demonstrate ways in which technology is used to enhance management training; briefly discusses characteristics that distinguish the senior manager target population from other training populations; and describes computer hardware and software characteristics appropriate to training.…

A computer model which simulates nutrient cycling helps students understand the pathways which elements follow. Examples of exercises which are designed to develop a more critical awareness of the literature dealing with nutrient cycling in ecosystems and a deeper understanding of the scientific method are discussed. (Author/IS)

Using this four CD-ROM disc set, teachers can have their very own math problem solving mentor as a leading expert in Singapore Math guides them through a lively presentation, working through math problems and explaining how Singapore has become the world's leading method in math. The expert's explanation of how to use Singapore's model-drawing…

This paper compares a number of different Computer Algebra Systems (CAS) in their solution of one-step and multi-step problems. The CAS programs considered include DERIVE, Maple, Mathematica, and MuPAD while the problems are taken from the final examinations of grades 9 and 12 in Estonian schools. The different outputs to one-step problems with…

This study investigated patterns and effects of cognitive tools usage during engagement with an open-ended hypermedia learning environment. Seven technical institute students engaged in problem-solving tasks concerning anatomy and physiology. They used 16 cognitive tools embedded in a hypermedia system and their tool use patterns and corresponding…

This paper discusses techniques and resources to use to stimulate creativity through a web site for several "generations" of gifted and talented learners. To organize a web site to stimulate creativity, two categories of development issues must be considered: intrinsic person variables, and process variables such as thinking skills,…

This study investigated whether it was more beneficial to provide the learners in computer-based learning environments access to on demand (self-regulated) help after they committed an error in problem solving or for the learning environment to externally regulate the presentation of instructional help. Furthermore, two different resentational…

Analysis showed that a word problem is difficult to solve if: it is of a different type from the problem that preceded it; its solution requires a large number of different operations; its surface structure is complex; it has a large number of words; or it requires a conversion of units. (Authors)

Describes a highly user-oriented conversational linear programing package for simulated laboratory experiences. The system allows easy problem entry, solution and changes, accepting free form statements of the problem and a few key words to describe each kind of input. (Author/TS)
