Web resource for visual aids
Jayda Pugliese at Lifehack has compiled a list of five computerized visual aid alternatives to PowerPoint. Each one includes some of the benefits and potential drawbacks and a link to a video showing how it works.
If you want to push your students a bit with visual aids — or overhaul your own visual aid options — this gives some interesting choices. Number 5 on the list says it is particularly good for students (or groups of teachers) preparing group presentations. The videos themselves may have potential to show and assess as informative presentations as a homework assignment or in-class activity.
