This page contains doorways (links) to a number of what I call â€œresource centersâ€ I have devised to help you in my courses. Each resource center contains several sorts of things. First, â€œpassive tutorials,â€ that is, short readings on how to do somethingâ€”say, cite a source or structure a paper. Second, â€œinteractive tutorials,â€ that is, interactive programs that give you additional practice on some skillâ€”say, constructing truth tables or identifying arguments. Third, links to either articles or video presentations that supplement what is discussed in classâ€”say, links to lectures on egoism or natural rights ethics. Fourth, suggestions for term paper topics (in those classes that require them). I am constantly developing these resource centersâ€¦some are fairly nearly finalized, others are just being developed. I welcome all suggestions for improving any of them. To open any of the centers, just right-click on its name.
