Classroom Demonstration
“Bullet Screen” for Virtual
Teaching and Learning: An Innovation for Online Collaborative Video Analysis
Classroom Demonstration
During Stage 1, we have
gathered information on existing commercial video sites with bullet screen
function and tested one in classes. We found that most sites with bullet screen
function (e.g., Bilibili, Tencent
Video, Youku Video) needs complicated registration
process that requires personal identity verification, which is not convenient
to use. Sites such as YouTube with bullet screen extensions (e.g., Dmooji) can be independently developed yet its
applicability is limited to selected video sites and it is not stable as the
video sites may change its configurations. For example, the Dmooji
tool tested in classes is no longer usable and the data entered by students
have been lost. Thus, it is crucial to independently develop a bullet screen
tool for learning.
In the proposal, we suggest
three methods to evaluate the project outcomes, which include 1) student
completed tasks on video analysis on the developed bullet screen in order to
evaluate their comprehension of the course material; 2) online questionnaire to
collect students’ thoughts about their learning experience; and 3)
Informal observation and discussion. In the current stage, we have used methods
1) and 3) to evaluate the on-going project developments. As explained earlier,
we have designed teaching tasks with bullet screen tool. During these tasks,
students can review the videos at their own pace and make comments. We have
also showed the whole video in a face-to-face class and found that bullet
screen can enhance hybrid mode of teaching. In another course, we used the
bullet screen tool in a zoom class to enhance virtual teaching and learning.
Informal observation and discussions have been conducted during and after
class. Achieving the objectives depends on the development of the bullet screen
online tool, which will be the main task of the project at this moment.
