A Modest ExperimentThis is a modest experiment in the pedagogical possibilities of some modern technology:
The sketches and pictures are intended as supplementary material to help students in their first encounter with vectors. I'm aiming for visceral understanding rather than a rigorous logical presentation, and this may lead me into troubles, e.g. chasing imaginary problems when clear simplicity would cut through better. Let me know! If I get ambitious, I may make a page on Lines, Children of Vectors.
- the World Wide Web has hypermedia capabilities which allow nonlinear use of documents of all types, and
- the geometry program used, the Geometer's Sketchpad , has some nice internal possibilities for unveiling, animating, and tabulating, in addition to its celebrated dynamic capabilities.
What you needExplorations are conducted with an interactive program, The Geometer's Sketchpad version 3. Earlier versions of Sketchpad won't work, but you can download a demo that will do the trick. (If you don't know where your browser puts downloads, search your computer for "GSP"). You also have to set your Web browser to use Sketchpad as a helper application. See my pages on using Sketchpad if you have questions about how to navigate through the sketches.
