One microscope and 80 kids? Are you kidding? No. The use of a microscope is feasible in the CAR classroom. Certainly not on a daily basis but microscopes can occasionally be used to show the students slides. Two strategies have proven successful to permit all the students to look at microscope preparations in an orderly manner. First, while the students are copying the resume off the board have them come up one at a time to look. A second possibility is to schedule an afternoon for the students to come and look at slides. Usually, the students are more than willing to come in the afternoon to use a microscope.
Some hints for microscope work:
1. Always use filtered water for preparations.
2. Slides and coverslips are available at the Peace Corps Medical Office.
3. Except for the blood slides, all of these preparations need to be prepared just before use.
4. It's highly recommended to take a flashlight to school on microscope days to prevent lighting problems.
