This study investigated the mental representations of student and professional engineers while they solved an engineering design problem. The intent was to gain a deeper insight into the differences that exist in the cognitive processes of engineering students and professional engineers as they use mental representations (i.e., propositions,…

In some higher education courses that focus on case studies, teachers can provide situated scenarios (such as business bottlenecks and medical cases) and problem-solving discussion tasks for students to promote their cognitive skills. There is limited research on the content, performance, and behavioral patterns of teaching using online…

Eye tracking was used to investigate how younger and older (60 or more years) adults use syntactic and semantic information to disambiguate noun/verb (NV) homographs (e.g., "park"). In event-related potential (ERP) work using the same materials, Lee and Federmeier (2009, 2011) found that young adults elicited a sustained frontal…

In this study we explore the strategies that undergraduate and graduate chemistry students use when engaged in classification tasks involving symbolic and microscopic (particulate) representations of different chemical reactions. We were specifically interested in characterizing the basic features to which students pay attention when classifying…

What is the connection between student success and their approaches to learning? Do learning approaches develop with university experience? We explored these questions by constructing profiles using a specially developed fixed response instrument and administering this to students at two similar South African universities. Groups consisted of…

The purpose of the study is to present research focused on validating the four algebra cognitive models in Gierl, Wang, et al., using student response data collected with protocol analysis methods to evaluate the knowledge structures and processing skills used by a sample of SAT test takers.
