Use item analysis to see student performance in quiz 1 and 2.
The Proscope HR in the podium Windows computer is a Pro-version, and offers different versions of filters. I could adjust filters to tune the color of images to show 'purple' and 'pink'. One problem is that there were too much dust on the len. The dust appears as round shaped cells and look confusing. I showed Bacillus and cocci sample using the 40X objective. I was unable to focus spirillum sample using Proscope on screen even using the oiled 100x objective. Maybe the Proscope lens really need to be cleaned.
