Second, Tufte, E. (2003) criticizes PowerPoint presentations by saying that merely flashing words or images on the slides won’t make the content relevant if they are not on point. The audience gradually gets bored of the presentation if the content is not appropriately supported and enhanced. According to Keefe, D. D. and Willett,
J.D. (2004), classroom instruction should be driven by the curriculum and appropriate content and not by the lavish use of technology. Further, McDonald, K. (2004) argues that focusing on graphics, animations, or sound effects more than course content, classroom discussion, or effective communication is a pitfall of PowerPoint presentation.
