摘　　要：师范生教学技能训练需要教师反馈和评价,而由于师生比例过大等因素导致教师的反馈和评价远远不足,系统利用视频标注技术实现了对微格教室三分屏视频的同时批注,并且可选择文字、手写和语音等多种批注方式,方便了教师远程在线点评学生的教学技能训练,方便了学生清晰有效地反思自己的问题,从而不断提升教学技能训练的效果。Teachers’ feedback and evaluation are needed in normal school students’ teaching skills training,but teachers’ feedback and evaluation are far from enough because of the large ratio of students and teachers.The system uses video annotation technology to annotate three-screen video of micro-classroom simultaneously,and can choose various annotation methods,such as text,handwriting and voice.The system is convenient for teachers to evaluate students’ teaching skills on-line,and students to reflect on their own problems clearly and effectively,so as to improve the effect of teaching skills training.
