This article deals with a theory-based investigation of the diagnostic problem-solving process in professional contexts. To begin with, a theory of the diagnostic problem-solving process was developed drawing on findings from different professional contexts. The theory distinguishes between four sub-processes of the diagnostic problem-solving…

The shift from traditional print materials to electronic resources, in conjunction with the rise in the number of distance education programs, has left many electronic resource librarians scrambling to keep up with the resulting inundation of electronic resource problems. When it comes to diagnosing these problems, words do not always convey all…

Data loss from life's little power calamities may be the most common form of IT disaster any campus can face. According to a 2007 industry association survey(www.connect.educause.edu/library/ecar/shelterfromthestormitandb/41174), 82 percent of higher education institutions reporting a disruptive occurrence in the five years prior to the study…

In two automotive air-conditioning classes, an experimental group (n=12) conducted laboratory activities structured by cognitive apprenticeship principles; 14 controls attended lectures. Cognitive apprenticeship was significantly more effective in increasing information acquisition, troubleshooting knowledge, and diagnostic skills. (SK)

Includes "National Trouble Shooting Contest--Training Technicians, Not Mechanics" (Wagner); "Front Wheel Drive on a Small Scale" (Waggoner); "Air Bags in Hit and Run on Rack and Pinion Technicians" (Collard); and "Future Technology--A Blind Spot Detector for Highway Driving" (Zoghi, Bellubi). (JOW)

Describes a practical application of hypertext that uses the "Guide" hypertext system developed at the University of Kent at Canterbury to supply customer support in diagnosing computing equipment problems. The underlying hypertext technology is explained, system monitoring is discussed, cost effectiveness is examined, and authorship is…

Suggests that a chief contributor to the continued economic success of the western economies will be the productivity gains available through efficient preventative maintenance planning and argues for appropriate changes in engineering curricula. Describes the formulation of maintenance planning problems and illustrates with numerical examples the…

This document discusses how students and schools can benefit from exchanging computer-aided design/computer-aided manufacturing (CAD/CAM) files over the Internet, explains how files are exchanged, and examines the problem of selected hardware/software incompatibility. Key terms associated with information search services are defined, and several…

Discusses methods for analyzing case studies of failures of technological systems. Describes two distance learning courses that compare standard models of failure and success with the actuality of given scenarios. Provides teaching and learning materials and information sources for application to aspects of design, manufacture, inspection, use,…

This paper encourages the use of Total Quality Management (TQM) tactics and other strategies as a practical means of fostering a quality culture in institutional research offices of higher education institutions. In particular, four approaches are advocated for understanding and minimizing errors: (1) use of TQM tactical tools to enhance work…

In computer-based simulations, students must bring a wide range of relevant knowledge, skills, and abilities to bear jointly as they solve meaningful problems in a learning domain. To function effectively as an assessment, a simulation system must additionally be able to evoke and interpret observable evidence about targeted knowledge in a manner…

A mental model is a knowledge structure composed of concepts and the relations between them. Mental models are distinct from declarative and procedural knowledge--they go beyond semantic relationships and skills acquisition and contain varied intellectual skills and knowledge. This study describes an initial investigation into the construct…

Discusses three experiments conducted with undergraduates to investigate important characteristics of mental models, their influence on task performance, and instructional strategies facilitating their formation. Results suggest that dynamic visual displays are more effective than static visual displays for teaching electronic troubleshooting…

Several studies have shown the difficulties students encounter in making sense of situations involving rate of change. This study concerns how students discover errors and refine their knowledge when working with rate of change. The part of the study reported here concerns the responses of four precalculus students to a task which asked them to…

A study found that the troubleshooting abilities of a treatment group of college students trained conventionally in a course called Aircraft Systems II and on a computer-based "Technical Troubleshooting Tutor" were better in some ways than those of a control group who trained conventionally without using the computer-based tutor. Aviation students…
