In the news is the PowerPoint slide presented to Gen. Stanley A. McChrystal, the leader of American and NATO forces in Afghanistan. It depicted, in a chart with many multicolored segments and connecting lines, the U.S. strategy in Afghanistan. As the article explained, McChrystal’s said, when he saw the slide: “When we understand that slide, we’ll have won the war.” The room “erupted in laughter.” http://blogs.geniocity.com/friedman/2010/04/there-is-no-shortcut-to-thoughtful-decision-making-it-requires-critical-thinking-and-discussion-and-powerpoint-not-only-doesnt-help-it-hurts/
There is a concern that PowerPoint can overwhelm, not add to, learning. I have seen many online teachers' proposed slide shows with multiple transitions and many colors and I think it detracts from learning. I do believe that PowerPoint can be effective in giving a talk to large audiences, but as for distributing reading material online the use may be limited.
