The students tyically post one or two comments per week. As I said earlier, I teach the same classes some many of my questions and comments are pre-prepared. Someone will always say they don't see a problem installing Windows on more than one computer. I have a long list of reasons why that is piracy and the URL to Microsofts website that explains what the license agreement is. That response takes about 10 seconds but it took 5 minutes to prepare. When I have a new class (one I have not taught), it takes about 12-15 hours per week the first semester with 20 students. The tasks required by the instructor is to respond to posts that address the questions asked and ensure the discussion continues with relavent topics. These are not the schools words, they are mine. Also check the teamwork assignments which is - create a word document, excel spreadsheet, and powerpoint presentations. The class is basic computer apps - not rocket science.
