3 Articles.

"Really Bad Powerpoint": The writer says that PowerPoint will be used all the time in different companies no matter what (most likely). It was made to help communicate with the marketing business, and it helps communicate to others verbally at the same time. The right side of our brains is sensitive and moody. The left side, however, is based on logic. Many times, people judge your presentation by the time the second slide is shown. Presentations are used to create, sell, and make more ideas arise. Four things to make a good presentation: make cue cards to hold onto, make slides that demonstrate what you are trying to say, then make a written document that includes footnotes and details, and we should also create a feedback cycle. It is very important that presenters do not hand out written notes in the beginning of the presentation, and not include more than six words on a single slide. Images should be professional, and transitions are best not to be used. Sound effects and print-outs are probably not advised either - because they don't exactly help.


"Help! My Brain is Overloaded!": This second article is talking from John Sweller's perspective, a man from the School of Education, found the "Cognitive Load Theory", which is basically when teaching does not help the way that we think and learn. This theory says that 'working memory' (part of the brain that gives storage) is needed for more complicated tasks, like lanuguage comprehension, learning, and reasoning. John Sweller also says that problem-solving areas focus on working memory - and teachers are better off giving students solved problems, so that they can learn those problems at home. Almost all information leaves right after twenty seconds or so, unless there was practice and rehersals. Teachers give students false information, which makes it harder for them to comprehend based on working memory, according to John Sweller. The same information can be organised in such a way, that it would be easier for us to understand. The "Cognitive Load Theory" says that working memory is only used when new information is being learned. And in a classroom dilemma, only limited material is going to be remembered, unless notes are being taken, or if they are handed out to them. PowerPoint presentations can go wrong if the information is the exact same as the verbal communication.

"The Science of PowerPoint Overload": This final article is based on the research of Richard E. Mayer. Mayer says that PowerPoint is the way that the human mind works, and that no more than five lines of text on one slide should be used. Presenters should reduce visuals by moving text off-screen, and to design a slide in the Notes Page view. This idea gives a better projected media experience, even if it means more work. This way, however, will make the PowerPoint easier for the audience to understand your topic. Bulleted points seem like they may be a good idea, but in reality, the information is actually harder to process. Show some pictures, but not too many, be sure to know what you are saying, and finally, keep it simple.
