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 reports on our design of a computer system which supports the understanding of how students construct their mental representation of references and how the construction failures impede their reading comprehension. Three modules, "User interface", "Recording", and "Feedback" were implemented. The…

The major purpose of this study is to assist college students in constructing mental representation of referential resolution in a computer system. Ninety students were asked to draw mental maps indicating the relationships between references, take reading comprehension tests, and fill out open-ended questionnaire. Results showed that the…

Describes a novel modeling and simulation package and assesses its impact on students' understanding of chemistry. Connected Chemistry was implemented inside the NetLogo modeling environment. Using Connected Chemistry, students employed problem -solving techniques characterized by stronger attempts at conceptual understanding and logical…
