Video annotation to enhance multimedia materials for CPR training course Presenter: Hsin-Chin Chen 1 Hsin-Chin Chen, Yueh-Min Huang and Der-Jiunn Deng Department of Engineering Science, National Cheng Kung University, Taiwan

2 Multimedia materials Among the materials, learners are interested in video material for learning. 1.Video 2. Figure and text 3.Text interface Favorite interface

3 Effect of video materials 1.When learners watch a video, they couldn’t deal with the content of the video in real time and result in the lower performance. 2. After reading comprehension test, the result showed a weak learning outcome by watching video. Video Test weak learning outcome

4 Multimedia materials 1.However, the video material is learners’ favorite learning style. 2.We add annotations on video to enhance learning outcome. Video Video annotation

5 Reading Comprehension test 1.Video Test Learning outcome? 2.Video annotation

6 Our Materials CPR

7 Video annotation tool Video with annotation to help understand the content of the movie in detail and enhance their impression.

8 Our experiments 1.Video The time is 20 minutes in every learning process. 2.Video annotation 20 students

Learner ’ s satisfaction for video annotation materials

13 Conclusion 1.We evaluate the learning effect about video annotation among two types of multimedia materials. 2.Video annotation material could reduce cognitive load and achieve the best learning performance among three types materials. 3. Annotations have a positive impact for learning CPR.
