Design of an Interactive Classroom with Bullet Screen Function in University Teaching

Classroom interaction is an important part of teaching which can greatly enhance the learning performance of students. However, the following problems still exist in conducting interactive teaching in conventional classroom, such as limited interaction format, lack of enthusiasm and unequal interaction frequency. As a widely adopted interactive tool in online video websites, the bullet screen is instant and convenient with high interactivity, which is extremely popular among the young generation such as university undergraduate students. In this paper, a software platform is designed to collect the bullet screen messages generated by students in classroom and display them instantly together with teaching materials such as lecture slides via projector, which can be later collected for teaching and learning performance analysis. This paper aims to propose a possible solution of the mentioned problems to construct a convenient and efficient interactive classroom to improve the teaching quality.
