Schaeffer, Math & Computer Science, Kutztown University of Pennsylvania Description: Schaeffer teaches a course called "Methods of Teaching Secondary Mathematics." Download the lessons created by his students that call on Geometer's Sketchpad, graphing calculators, and Microsoft Excel. Lesson topics address parallel lines, box and whisker plots, scatter plots, polar "rose curves," matrices, Cramer's Rule, balancing checkbooks, baseball statistics, and more. See photographs of dozens of his math ed students' colorful bulletin boards, featuring worksheets and documentation on interactivity and directions for use. Download PDF tutorials on piecewise-defined functions on a graphing calculator, getting started with Maple, Newton's method on a graphing calculator, one-variable statistics on a graphing calculator, box plots on a graphing calculator, naming large numbers, and naming polygons. Math Trivia includes an animated puzzle for matching the terms obelus, octoorthorpe, vinculum, and virgule with their symbols. Also, study guides for courses that Schaeffer teaches, such as Applied Statistical Methods, and Calculus I; and professionally-drawn graphics of number lines, grids, axes, rulers, protractors, 3D geometric objects, and graphs of trigonometric functions.
