Chih - Kai TITLE Record Desktop Activity as Streaming Videos

As Web-based courses using videos have become popular in recent years, the issue of managing audiovisual aids has become noteworthy. The contents of audiovisual aids may include a lecture, an interview, a featurette, an experiment, etc. The audiovisual aids of Web-based courses are transformed into the streaming format that can make the quality of Internetbased videos acceptable to learners using a limited bandwidth. Although streaming technique enables learners' accessibility of audiovisual aids over Internet, the usage of audiovisual aids still totally adheres to instructors' perspectives. In fact, distance learners can contribute ideas not only in text format, but also in audiovisual format. However, previous research has not considered the feasibility of audiovisual aids contributed from distance learners. This paper argues that the usage of audiovisual aids from distance learners' perspectives should be considered in designing Web-based courses. To demonstrate this concept, this paper first introduces a screen camcorder tool that enables learners to record screen activity as videos in standard format or streaming format. Then, a collaborative learning strategy called Jigsaw II is applied to encourage expertise group streaming videos for training other learners. Finally, a preliminary survey of technology acceptance is implemented on 37 learners. Results confirm the feasibility of audiovisual aids contributed from distance learners.
