Sketch
-- part contents for card part 7
----- text -----
Sketch is a computer-based tutor concerned with the graphing of algebraic expressions. The program includes a built-in model for problem solving, a coach for helping students to apply the problem solving model, an option that allows students to "turn off the tutor" and experiment, a collection of instructive examples (easily expandable by the teacher), a facility for entering arbitrary new problems as the program is being run, and the capability of solving any problem of a certain class.
Sketch helps students to develop skills of visualizing and quickly sketching graphs of simple algebraic expressions. It teaches a systematic approach to the sketching of curves, emphasizing a step-by-step procedure for transforming a simple expression into a more complex one and transforming the graph accordingly, rather than the plotting of individual points. Sketch handles expressions containing a single non-arithmetic function; it can guide the graphing of any such expression. Sketch provides appropriate instruction for any problem within that class, including those entered by a student or teacher.
Sketch is a program of considerably greater flexibility than is usual in computer based instruction. It has been tested with several hundred public high school students from districts in Allegheny County, PA. Development has been supported by the National Science Foundation, Grant No. MDR 8470166.
