Abstract
This paper reports on a year-long technology-rich teaching experiment conducted with four
low-achieving undergraduate students. Using questionnaires, classroom assessment tasks,
self-report journals, interviews and field notes, the study identified three stages of cognitive
development - computational, technician, and multirepresentational - which reflect
successively higher levels of tool-based engagement and performance. Four tool-based
pathways or "journeys" were also identified, illustrating how these mathematically weak
students navigated their way through the stages of the model. They are: a restricted learning
pathway, a linear learning pathway, a non-linear learning pathway, and multiple learning
pathways.
