The concept of "explanation" is the focus of this study and of the working computer programs contained in it. The advent of the computer makes it possible to bring to bear on the art of explanation a vast information handling power. In the first sections, a definition of explanation, its differentiation from related subjects, and the more than 50…

Describes a four-phase method of helping students who are mathematically unsophisticated and have difficulty relating their common sense, English-language understanding of a system to an abstract, mathematical description. The approach uses interactive simulation models. (Author/IRT)

The Educational Technology Center has attempted to develop a series of computer based learning environments to support the learning and application of multiplicative reasoning. The work and software described in this paper, including the teaching experiment that generated the error phenomena examined, is part of a larger ongoing research project.…

A two-year investigation into the development of computer-assisted instruction (CAI) for the improvement of undergraduate training in statistics was undertaken. The first year was largely devoted to designing PLANIT (Programming LANguage for Interactive Teaching) which reduces, or completely eliminates, the need an author of CAI lessons would…

Describes program operation, applications, and teacher and student opinions of DELPHI, a computer program used in a wide variety of subjects which allows students and instructors to enter questions anonymously for others to answer. These question-answer pairs are then presented to other students or the instructor for comment or evaluation. (MBR)

Suggests that a solution to the problem of expensive educational software may be found in public domain software. Included are a definition of public domain software, a discussion of the kinds of software that are in the public domain, ways to obtain such software, and a list of some examples. (PK)
