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…

Compares 7 biology faculty members, 9 genetic counselors, and 26 undergraduate students according to both expertise and problem-solving success within the domain of genetics. Findings are consistent with the hypothesis that as expertise is attained, the individual restructures knowledge into a framework based upon the critical dimensions which…

A study compared university chemistry students' (n=19) performances in creativity exercises, concept mapping, and traditional examinations. Performance in all three correlated with deep study strategy, but low correlations between the three methods suggests that they test different aspects of chemistry knowledge. Use and integration of all three…

Discussion of differences between problem-solving techniques of novices and experts suggests that both the experts' mental model and common novice problems can be derived from analyses of several expert and novice protocols. Three instructional strategies based on these differences are discussed, including the use of a computer simulation to solve…

This study explored how regular teachers (N=20) and special education teachers (N=20) think and make instructional decisions about special needs students. Teachers viewed a videotape of a reading comprehension lesson for a small group of third grade students. One student was a target for observation and classified as learning disabled.…

There have been few discoveries in geology more important than "deep time"--the understanding that the universe has existed for countless millennia, such that man's existence is confined to the last milliseconds of the metaphorical geological clock. The influence of deep time is felt in a variety of sciences including geology, cosmology,…

The IADIS CELDA 2012 Conference intention was to address the main issues concerned with evolving learning processes and supporting pedagogies and applications in the digital age. There had been advances in both cognitive psychology and computing that have affected the educational arena. The convergence of these two disciplines is increasing at a…
