Context for Use
Teaching Notes and Tips
These modules were developed as essentially self-paced, take-home lab assignments. Students are supposed to work through the modules, slide by slide, building their own worksheets as they go along, taking note of instructions and prompts, hints, and queries.
Students must have access to compters equiped with a spreadsheet program such as Excel.
This module is one of several developed by Dr. Vacher. The module presentation can be found at http://www.evergreen.edu/washcenter/modules/moduleList.asp
The Powerpoint file is considered to be the student version. There is also an instructor's version that has active spreadsheets in it. There are instructions for requesting this version on the website.
