Resumo

The use of video as instructional content has become popular in web-based learning environments. Considering that there are fragments of a video lecture that may be of particular interest, in our study we analyzed the effects on interaction behavior and on students' perceived experience of providing an instructional video enriched with an interactive timeline highlighting points of interest. We offered a content test for a control group and an experimental group. In the former, participants used a video player with a conventional timeline. In the latter, participants used a video player with an additional interactive timeline indicating points of interest, corresponding to topic transitions in the lecture, which provided direct access to the point where a topic is introduced. Our findings indicate that the annotated interactive timeline affected students' behavior and improved their personal experience and efficiency in terms of interaction in video-based tasks. The experimental group significantly performed a lower number of clicks to find information and also reported diminished perceived workload scores when compared to the control group. Also, participants in the experimental group presented a more predictable and patterned search behavior than participants in the control group. (AU)
