This report presents results of several extensive empirical studies. Prior to these studies it was believed that errors in procedural skills such as multi-digit subtraction could be accurately modelled with two mechanisms: bugs ("competence" phenomena reflecting mistaken beliefs about subtraction which are stable over time) and slips…

The past few years have seen a proliferation of microcomputers and a reduction in their cost. Many children have microcomputers in their homes and have learned their use in playing games and solving problems. Among these programs are those designed to improve reading skills, many of which are somewhat poorly conceived and prepared, often being…

Computerized spelling programs or "spelling checkers" can be a wonderful tool for writers at any level of competence. However, they should not be used as adjuncts to the teaching of writing unless they meet two boundary conditions, one of size and one of design. The problem with design of the programs is that they allow for the…

This paper contains the technical specifications, schematic diagrams, and program printout for a computer software package for the development and administration of diagnostic tests. The second version of the Diagnostic Testing Package DX consists of a PASCAL-based set of modules located in two main programs: (1) EDITTEST creates, modifies, and…

Thirteen papers from a symposium on technology in education and communications for the deaf are presented. The following papers are included: "Technology Trends in Special Education" (C. Blaschke); "Microcomputer Usage in American Schools for the Deaf: The State of the Art" (M. Deninger); "Management and Computers"…

The events associated with the demise of a software firm (AXXESS, Inc.), which supplied a software package to higher education institutions are reviewed. Attention is directed to what was learned that might be of assistance to other colleges using or considering third party software. Some of the topics include: particular crises, legal…

This paper discusses the incorporation of heuristics in computerized decision aids that are used for structuring decision problems. Decision theory is described in terms of linked subsystems, and sites where it is necessary to employ heuristic rather than normative, algorithmic procedures are identified. Production systems are then used to…

This manual for a workshop on the use of telecommunications in the schools begins by presenting a connection decision chart, the session objectives, and the agenda. Information presented for the workshop covers the basic concepts and elements of telecommunications; the specific elements of a telecommunications system; the evaluation and selection…

Summaries are presented of five conference papers on communication, control, and computer access for handicapped individuals. Papers have the following titles and authors: "Accessibility of Graphically Based User Interface Computer Systems for Individuals with Visual Impairments" (Charles Lee and Gregg Vanderheiden); "Data Base vs. Information…

This study focuses on the effectiveness of "Solutions Unlimited," a computer software program developed to teach problem solving to middle level students. Fifty-one fourth, fifth, and sixth graders (21 girls and 30 boys) attending a private school in a small mid-west community were the subjects for this experiment; none had received…

Three aspects to be considered when teaching a one-semester beginning economics statistics course are coverage, mastery, and applications. There is a difference between coverage and mastery. Moreover, mastery is not an end in itself; instructors must consider how statistics courses will influence students' approaches to other subjects and…

This update on computer technology--as it affects learning assistance directors and developmental education personnel--begins by reporting on new developments and changes that have taken place during the past two years in five areas: (1) hardware (microcomputer systems, low cost PC clones, combination Apple/PC machines, lab computer controllers…

Designed to help explain library automation to the librarian or student, this handbook presents a case to be solved, i.e., the creation of a book acquisition system for a special library; the steps to be taken to solve the problem; and a users' manual for the system to be provided to the client. The handbook is divided into three major sections:…

Recent studies indicate that the principal is key in planning for change and that innovations can succeed when the principal as change facilitator shares responsibility with others--assistant principals, teachers, and parents. This paper discusses two areas: (1) student learning enhanced through cultivation of critical thinking skills; and (2)…

This publication updates the 1982 occasional paper that was intended to foster staff awareness and assist colleges in Great Britain considering the use of computer-aided design (CAD) material in engineering courses. The paper begins by defining CAD and its place in the Integrated Business System with a brief discussion of the effect of CAD on the…
