I'm still having problems with my computer after Microsoft applied an update. So far, Microsoft has been unhelpful. It has made my search harder because I have to borrow a computer to do it.

I found one paper that I found interesting. Two colleges, a 4 year and a junior college, ran similar introductory chemistry courses. Although not identical, they were designed to be very similar. The 4 year college had a traditional class with laboratory while the junior college offered an online class with a lab portion performed at home by the students. At the end of the year, both classes had a lab practical that required the students to be tested at the laboratory with comparable evaluations. You can guess what the outcome was: the online junior college students received better grades. Interesting.
