In some ways, PowerPoint presentations have become the “five paragraph essay” [of] yesterday. Most of us who’ve taught English for more than fifteen years remember that monstrosity. The five-paragraph essay was an attempt to standardize writing in order help students mold their writing to fit standardized test scoring. Needless to say, as a teaching strategy, it was more about getting high scores on state writing tests than about students expressing original ideas and thoughts. It certainly wasn’t about creativity and innovation. PowerPoint presentations as projects in many ways have replaced those five-paragraphs essays; they are simply a standardized way for students to present information.
