Access to handouts of presentation slides during lecture: Consequences for learning

摘要

Teachers often lecture with presentation software such as Microsoft PowerPoint; however, little research has examined the effects of this new technology on learning. One issue that arises is whether or not to give students copies of the lecture slides, and if so when. A survey documented that students prefer to receive lecture slides before class, whereas instructors were less pronounced in their preferences. Two experiments examined whether having handouts of the slides facilitated encoding of science lectures. Having access to handouts of the slides during lecture was associated with a number of benefits: less note-taking (studies 1 and 2), less time needed to prepare for a final test (study 1), and better performance on the final test (study 2). Overall, receiving handouts before lecture helped efficient encoding of the lecture. Copyright © 2009 John Wiley & Sons, Ltd.
