In the 2006 TxDLA Conference, I happened to step in a room, and heard an interesting presentation, which discussed the abuses and misunderstandings of employing PowerPoint slides in the online courses. As a fact, PPT slides, which were used to show figures, key points, and so on, in the face-2-face presentations have been used extensively in online courses nowadays. However, uploading the PPT slides used in a traditional classroom to WebCT, is that all?
 

Very often, no. Although the subject matter is the same, many differences exist between the traditional classroom and the online classroom:

-The class settings are different.

-The students are different.

-The way to teach is different.

All in all, it can be regarded as one thing: the approaches of achieving successful communication and information delivery are different. What should we do, then, to adapt to these differences?
