Presentations are a means to package relevant content, project it on to a screen and present the content in a controlled manner to an audience. You could use it for different kinds of content, use different media and embellish it in different ways. You could use it to teach a lesson in your class, present a report of an activity in a parents-teachers meeting, or present a paper in a seminar or conference.
As a teacher you would have experimented using the blackboard. The blackboard has the advantage of a foolproof, fail safe technology. Chalk is always available and with some regular repainting, you are ready to communicate. You would certainly have used it for a variety of presentations ranging from plain text, to illustrations, to detailed drawings, flow diagrams, and graphs. Never has your blackboard failed you.
But still many schools are opting for computer based projectors for their presentations. And no one says using this new medium is as easy as using the blackboard. Apparently, there are very strong reasons for using the hardware and software to make presentations.
This course tries to take you through some of the arguments for using computer based presentations. We will constantly try to compare it with the blackboard and ask whether it is worth all the hassle. You may at the end of the debate be convinced that computer presentations are a great leap forward. You may also conclude that all these bells and whistles (effects that can attract and entice but have no educational purpose and can get boring if repeated often) are not worth the effort, because it does not contribute to better learning. In either case, it would be worth your time and effort to critically examine each aspect of these technologies and come to a considered opinion.
