The Power of PowerPoint

Many studies have investigated the value of using PowerPoint as a lecture tool. PowerPoint’s strength is often the comfort we have as educators and learners with this lesson delivery format. But sometimes, our comfort level with PowerPoint can lead us to over-anticipate the role it plays in communicating complex ideas. 

Most research on the effectiveness of PowerPoint shows that the software itself has no impact on students’ memories or their assessment scores (Clark 2008, Mehta et al 2017). Many criticize text-only PowerPoint lectures as being overly simplistic and impersonal. Bulleted lists are often overused. Text can be incomplete, and not meaningful outside of the in-lecture context. Slide decks are sometimes constructed too quickly, without consideration for learning activities or multiple modalities. Graphics and video are often underrepresented and slide decks are often reused each semester, without revision or reflection. Some researchers caution that PowerPoint can “zone out” an audience, neutralizing student-to-student interaction completely (Holstead 2015). 

Further, a poorly assembled slide deck can detract from the quality of learning during presentations. PowerPoint can sometimes be too presenter-friendly, letting us record all our talking points right on the slide, conveniently organizing thoughts and jogging memories. Because of this, it becomes easy to create large PowerPoint slide decks, in the urge to be thorough in covering all the content. But large slide decks are not useful presentation or study tools, and often leave facilitators and learners scrambling to “get through” the content. The driving force of the lesson delivery becomes the facilitator’s voice and personality, rather than active learning of content. 

The best use of PowerPoint, then, is to keep it learner-focussed. PowerPoint seems to have some real virtues for explaining tasks, representing visuals or anchoring concepts. Consider engaging in “active lecturing,” where you might integrate direct instruction, active learning principles and experiential learning (Clark, 2008). Well-designed PowerPoint slide decks can improve student retention of subject matter knowledge, and help students review for tests and exams (Clark, 2008). Students report feeling more engaged and interested in course content when presented in PowerPoint (Holstead, 2015). When combined with annotations on the slides or board to clarify and illuminate definitions, diagrams and key concepts, students report that they pay better attention, enjoy the approach, and would like more lessons structured this way (Swati, 2016; Mehta, 2017). Building in active learning strategies, like discussions, games or reflections, also leaves students hungry for more (Fratto, 2011). 

If a facilitator combines knowledgeable content delivery with active learning practices, a course using PowerPoint could certainly avoid the perils of “sage-on-the-stage” and effectively help students attain course outcomes.
