摘　　要：镜头切换影响精品资源共享课的录制效果和质量,教学录像的质量高低直接影响学习效果。这项研究采用目的性抽样,选取10所高校、30门精品资源共享课的教学录像进行浏览和学习。研究发现,有60%的高校精品资源共享课教学录像采用无技巧切换(直接切换)方式,平均镜头切换频率在1到2次之间的课程比例达到53.3%。在录制教学录像中,镜头的切换不仅要把握教育教学、心理学方面的原则,而且要遵循影视节目制作、镜头语言方面的规律。Lens switching affects the quality in the video recording of exquisite courses for higher education which directly affects the learning effect for learners. The study, using purposive sample, has selected and studied 30 video recordings of exquisite courses for higher education in 10 universities. The study shows that 60% of exquisite courses for higher education use direct switching mode while 53.3% switch lens by one or two times per minute. In the recording of teaching video, the lens switching should follow not only the principle of education and teaching, but also the laws of the video program making and the lens language.
