Student Thinking With a Non-Traditional Linear Coordinate System
Page: 476
This study explores different ways that linear algebra students reason with a non-traditional linear system, referred to as the Gulliver system, in a task-based clinical interview. Using the constructs of Naming and Locating developed in the conceptual framework, an a priori analysis outlines how students may engage in Locating and Naming tasks. The a priori analysis was used for data analysis as a basic framing. Students’ engagement with the non-traditional linear system and the refined and extended a priori analysis will be presented. Students’ adoption of their previous experience with the Cartesian coordinate system will be also discussed.
