Cognitive scientists investigate mental models (how humans organize and structure knowledge in their minds) so as to understand human understanding of and interactions with the world. Cognitive and mental model research is concerned with internal conceptual systems that are not easily or directly observable. The goal of this research was to…

This study investigated the effects of solution-oriented and strategy-oriented feedback when using interactive computer-assisted instruction. The feedback confirmed problem solving strategies that were either similar to the learner's cognitive strategies (i.e., spatial strategies) or different from the learner's cognitive strategies (i.e.,…

This paper describes a method of understanding student problem-solving behavior during computer-assisted instruction using trigonometry as the example domain. Instead of attempting to model the student's process for solving problems, techniques which infer the equivalence between two adjacent steps in the student's process are used to determine…

In order to study the processes people employ in reading technical material and the ways in which information engineering can facilitate those processes, 13 adults, including electrical engineers, stockboys, secretaries, graduate students, and teachers, were asked to perform an assembly task by following concise, step-by-step instructions provided…

A study examining the effects of computer animation exercises on cognitive development asked two groups of seventh graders to create computer animations, working from a simple mythic text. The ability of students to create narrative scenarios from this mythic text was analyzed. These scenarios were then recreated in the school computer lab, using…

This paper discusses systemic problems with testing and outlines two scenarios for reformulating testing based on intelligent tutoring systems. Five desiderata are provided to underpin the type of testing proposed: (1) tests should emphasize learning and thinking; (2) tests should require generation as well as selection; (3) tests should be…
