Video annotation for enhancing blended learning of physical education

Blended learning is becoming one of the important applications by integrating e-learning and traditional face-to-face instruction together. As an introduction to the reader challenges in hybrid learning of physical education are provided firstly. In this paper, Video Annotation Module (VAM) is presented to improve blended learning of physical education. Through the user interface of VAM, the teacher can review the student's actions video, pick out the wrong actions and add still annotations. And the student can watch annotated video to find out mistakes and get instructions. In order to control over bandwidths Geometry Primitive Language is proposed, which presents the geometry primitives in XML. The results of experiment show that 80.9% out of students think that the VAM can afford the blended learning of physical education.
