A reexamination of the traditional instruction of introductory computer science (CS) courses is becoming a necessity. Introductory CS courses tend to have high attrition rates and low success rates. In many universities, the CS department suffered from low enrollment for several years compared to other majors. Multiple studies have linked these…

Computer-based problem-solving examinations in immunology generate graphic representations of students' search paths, allowing evaluation of how organized and focused their knowledge is, how well their organization relates to critical concepts in immunology, where major misconceptions exist, and whether proper knowledge links exist between content…

Describes a computer-based methodology for representing mental models as maps, extracting these maps from written and spoken texts, and analyzing and comparing concepts and structures of information within maps. Illustrates the model using data on students and teacher in an undergraduate writing class. Contains about 80 references. (Author/SV)

Discusses the problem of establishing terminology for mental models, attempts to sort out the various meanings found in the literature, and offers definitions that could help in developing a more standardized terminology for discussing issues of concern to researchers in human-computer interaction. The role of mental models in learning and using…

The early stages of a microcomputer-based project to integrate managerial knowledge and practice are described in this report. Analysis of the problem-framing process that effective principals use to reduce complex problems into more manageable ones forms the basis of the project. Three cognitive-mapping techniques are used to understand the…
