Students seeking certification at Texas Tech University to teach K-4 must complete a nine hour sequence of mathematics courses taught in the Department of Mathematics. The first course in this sequence is College Algebra taught in special sections reserved especially for these students, "Clustered" College Algebra. A paper describing this 9 hour mathematics sequence is to appear in PRIMUS. ["The Nine Hour Mathematics Sequence for the General Pre-service Elementary Teacher at Texas Tech University," Gary A. Harris & J. Dalton Tarwater] Here we include some of the supplemental exercises that are designed to introduce the students in "clustered" algebra to one of the modern technologies that is having such a tremendous impact of the curriculum and instruction in mathematics education at all levels, the "super graphing calculator".
That it is necessary for today's and tomorrow's teachers to be competent and comfortable with this technology is well established. We quote two sources. The first is from the NCTM CURRICULUM AND EVALUATION STANDARDS FOR SCHOOL MATHEMATICS.
The second is from A CALL FOR CHANGE: RECOMMENDATIONS FOR THE MATHEMATICAL PREPARATION OF TEACHERS OF MATHEMATICS, MAA NOTES, 1991.
The mathematical preparation of teachers must include experiences in which they use calculators and computers:
