For many of us, PowerPoint has likely become a very common tool in the toolkit of educational technology; it's nearly unavoidable. And it does have some great learning affordances. Isseks points out the uncreative and noneducational ways this tool is being used in schools.
First, Isseks points out that PowerPoint often presents a one-sided presentation with little or no room for dialogue, leaving students with little room for discussion, analysis or evaluation. [Bloom's Taxonomy] He further notes PowerPoint 'covers' materials well though it often does not lead to the understanding of those materials.
Effective use of PowerPoint can be achieved (and I'm resisting the urge to place these ideas into bullet form) in a number of ways. First, many of the bullet points should be removed. Here he explained presentations should feature more questions than answers. Second, fancy transitions and sound effects should be eliminated. Third, keep on the classroom lights.
