Abstract
A CAS-active introductory calculus course was trialled with three year 11 classes of students
who each had a TI-92 calculator. Access to the CAS enabled the students to perform "year
12" differentiations with the same level of success as year 12 students, but without affecting
their conceptual learning or their development of by-hand skills. The use of the CAS was
influenced by teachers' cognitive "privileging". Some observations are made on the suitability
of the TJ-92 for such a course.
