Abstract: Clickers can be used in courses for many different purposes, and the effectiveness of their use depends on the purpose for which they are used. We have used clickers for three years in three trailer sections of General Chemistry I. (1) The first year we used them two or three times during each 85-minute lecture period to increase student attention and attendance. Short-term learning was compared with that in a comparable section taught by traditional lecture techniques. Different hour exams were used, but a common final was given. No significant difference was found in the clicker and clicker-free classes. (2) In the second year we used clickers in a more intensive and structured manner. To make time for more clicker uses, we omitted lectures on certain simple concepts, told the students to read those sections, and gave them instruction on how to read scientific material. We also gave them Reading Comprehension clicker questions from practice MCAT exams. Anonymous clicker surveys showed that the number of students reading and comprehending the text approximately doubled (from 13% on March 8 to 29% on April 17). At the same time the test scores became significantly higher than in the clicker-free class, as did the common final exam scores. (3) This year we are trying clickers with an emphasis on supplying lecture outlines online; survey results for this variation will be compared. Already we note that attendance remains high (85%) even though lectures are online.
