A Mathematica-based CAL matrix-theory tutor

Under the TLTP initiative, the Mathematics Departments at Imperial College and Leeds University are jointly developing a CAL method directed at supplementing the level of mathematics of students entering science and engineering courses from diverse A-level (or equivalent) backgrounds. The aim of the joint project is to maintain — even increase - the number of students enrolling on such first-year courses without lowering the courses' existing mathematical standards. A CAL tutor for matrix theory is presented in this paper, in the form of Mathematica Notebooks.
