20(3)pp55-86TeachingSupplement3.pdf FROM THE EDITOR Daniel E. Flage gives us a flow chart that illustrates one way of organizing many critical thinking questions, and of seeing how they work together to evaluate reason- mg. Written exercises such as the one from Steven C. Combs will help students to orchestrate those evaluative questions. He has used his exercise for a number of years because it has stimulated the production of good papers and discussions. Ron Leonard gives us an innovative way oftesting the validity of disjunctive syllo- gisms that would be appreciated by students who think vi sually. Tim van Gelder informs us of valuable critical thinking sites on the Web. John Bryant reports to us a way of planning student participation at the beginning of a semester, and suggests a modification of the standard True/False question .
