Here the assignment was designed to highlight the relevance of statistical ideas, and to aid in data fitting in laboratory experiments. Also it was seen as important for the students to be able to white a short coherent report on a given data set. But the TI-92 offers much more than is usual 4. The matrix features are easily used by students. The programming features also help provide a much more geometrical view of matrices than is usually the case.
Students can obtain interesting results quite quickly and easily.
This is a very impressive feature. Time constraints prevented any extensive investigations beyond vectors and trigonometry, but the potential is enormous. Although the language is fairly straightforward, it does take students some considerable time to get used to writing programs. Interesting ideas can easily explored with relatively simple programs. The possibilities here are virtually unlimited.
