Abstract
With the availability of new information technology, PowerPoint presentations have been used extensively in classrooms for higher education, in addition to traditional chalk-and-talk presentations. However, their effectiveness is much less clear. The main purpose of this paper is to examine whether or not downloading PowerPoint slides before a class has any impact on students’ learning outcomes for that class, using a panel data set.The estimation results show a nontrivial lecture slides effect. After controlling for students’unobserved individual heterogeneity and exam difficulty, downloading lecture slides before a class improves students’examination performance by 3.48 per cent. This finding suggests that instructors could help students improve their academic performance by supplying PowerPoint slides.
