I found the fifth question on the quiz about concrete vs. abstract application of knowledge problematic. It stated that "The instructor of a culinary arts program asks her students to identify the differences between natural and processed cheeses." I realize that concrete thinking involves the 5 senses, but the module defined abstract thinking as "seeing connections and applications." Had the instructor asked students to define or list the qualities of each type of cheese, I can clearly see it would be concrete. But identifying differences between two different things, to me at least, sounds like an example of "seeing connections," which would constitute abstract. Would you clarify this problem for me? Thanks.
