Recent studies have indicated that college undergraduates have retained little understanding of the information in the science courses they have taken when they graduate. Science is taught as detailed, factual content, and most students are evaluated by their ability to recall and summarize the information provided. As such, students concentrate their studies on terms and definitions, spending little time on application and analysis. To correct the problem, instructors are encouraged to formulate more questions around the mid and upper levels of Bloom's taxonomy in the examinations they prepare. (Contains 3 figures.)
