First Time

The day I held a graphing calculator for the first time, I decided to use it as a tool to teach transformations of functions. After years of revisions and many calculators later, this lesson is still one of my favorites. Whether I am teaching algebra, trigonometry, or calculus, this topic is universal and as necessary to students struggling with high school mathematics as to more advanced students.

First Time

An important article by Professor Robert A. Hume, “Shall We Be More Practical?” School and Society, January 2, 1943, links together (not for the first time, to be sure) the fortunes of the pure mathematics in the high schools and colleges with those of the ancient and modern languages. We language advocates must never forget, he says in effect, that when educationists swing their cudgels at the heads of algebra and geometry, our own heads are in danger; and by the same token when they “crack down” upon the languages, algebra and geometry and all their kith and kin had better look to themselves. You have yourself no doubt noticed that the writers who belabor high-school mathematics in the lay and professional prints often couple the foreign languages with them as participes criminis.

Art Of Teaching

The term “High School Mathematics” to the layman is the cognomen for a series of courses enabling a student to cover their college requirement in the math field. And for many years, because the efficiency of a school was so readily ascertained by college board results in those subjects, the tendency has been for pedagogues, themselves, to concentrate heavily on the techniques of teaching algebra and geometry.

The use of a graphing calculator can encourage explorations that take the explorer well beyond a mundane exercise to look more deeply into a concept. The exploration described in this article was prompted by a routine exercise undertaken in a graphing-calculator workshop with high school mathematics teachers. The availability of technology reduced the tedium of calculation and extended what started as a minor exercise into a full-fledged, open-ended, ongoing mathematical exploration. Such experiences are the rule, not the exception, when one is teaching with technology. They can be generated by a teacher or a student.
