This study investigated the effects of visual cues in multiple external representations (MER) environment on the learning performance of novices' program comprehension. Program codes and flowchart diagrams were used as dual representations in multimedia environment to deliver lessons on C-Programming. 17 field independent participants and 16 field…

Two experiments investigated effects of emergent features on perceptual judgments of comparative magnitude in three diagrammatic representations: kiviat charts, bar graphs, and line graphs. Experiment 1 required participants to compare individual values; whereas in Experiment 2 participants had to integrate several values to produce a global…

Describes and compares three approaches to task analysis--behaviorally-based, concept-based, and cognitive process-based--and provides four tentative recommendations for determining which approach is appropriate in a particular situation. Five flowcharts and fourteen references are included. (MBR)

This discussion of information structures in written texts describes how linguistic analysis of short published reports leads to the presentation of an algorithm that depicts the problem-solving process in terms of a series of evaluative questions. (Author/CHC)

Describes study that was conducted to determine whether the search process is the same for academic, public, and school library users. Cognitive models of information seeking are discussed, users' attitudes during the search process are described, the role mediators play is examined, and future research needs are suggested.

This study examines the effect of the "Technical Troubleshooting Tutor," a computer-coached training program, on aircraft electrical system troubleshooting. Performance ability differences between control groups are noted, and troubleshooting models and flow diagram examples are included. The study demonstrates the possibilities for…
