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 computers equipped with a spreadsheet program such as Excel.
