You need to do the necessary work outside of class, and when you are in class, you need to listen actively. To assess whether you are an active listener, consider the following pairs of statements. Place a check next to the statement in each pair that more closely describes your classroom listening style. n 1a. When I’m listening in class, I lean back and get as comfortable as possible. n 1b. When I’m listening in class, I sit upright and even lean forward a little. n 2a. I let the instructor’s words wash over me, generally going with the fl ow of the lecture. n 2b. I try to guess in advance what the instructor is going to say and what direction the lecture is taking. n 3a. I regard each lecture as a separate event, not necessarily related to what the instructor has said before or will say the next time. n 3b. As I listen, I regularly ask myself how this relates to what was said in previous classes. n 4a. When I take notes, I try to reproduce the instructor’s words as closely as possible. n 4b. When I take notes, I try to interpret and summarize the ideas behind the instructor’s words. www.mhhe.com/messersmith CHAPTER 4 emPOWERme 341
