摘 要：为做好线上教学工作，我校计算机公共基础教学团队充分利用慕课堂、学习通、钉钉等形式开展线上直播教学，并创新性的采用“N+M多对多三环启发式”教学模式，破除传统的个人教学的模式，建立了课程组线上协作研讨的团队式教学，改变了传统满堂灌的教学模式，建立了三环启发式教学新模式。课堂上一个老师主讲，其他课题组参与老师补充，课程组老师针对主讲老师讲解的内容进行提问，从而激发和引导学生积极参与提问，使学生变被动学习为主动思考、主动参与的研讨式学习，保证了线上教学效果。

【Abstract】：In order to perform online teaching well， the computer teaching team of our college has made full use of Moocs， Xuexitong，Dingding and other forms to carry out online live teaching， and has made innovative use of "N + M Many-to-many three-ring heuristic method of teaching" mode， which breaks the traditional mode of individual teaching and sets up a team teaching mode of on-line collaborative discussion of the course group， and breaks the traditional teaching mode of full classroom and establishes a new three-ring heuristic teaching mode. In class， one teacher gives the lecture while other members of the task group take part in the teacher's supplementary work and ask questions according to the content explained by the teacher， thus inspiring and guiding the students to actively participate in the questioning， so that students will change passive learning into active thinking and active participation in the seminar-based learning atmosphere， and eventually ensures the online teaching effect.

0引言

近两年线上线下相结合的教学模式开展的越来越广泛，线上授课开启了教学的新形式，使学习跨越了时间和空间的界限，在老师与学生们之间架起学习的桥梁[1]。本文以高职院校《医学计算机与信息素养》理论、实验课线上教学为例，钉钉直播和中国大学慕课在线学习平台相结合的形式，进行线上教学模式的应用实践研究。

1线上教学模式改革的前提条件

（1）在线教学特点。线上教学教师和学生完全物理隔离，出现教学时空分离、教学行为分离等现实问题，线上学习形式的改变要求教师必须重视学生线上学习内容的安排和活动的组织，开展灵活多样的教学活动，重视学生之间的在线交流互动，重视综合运用在线测试、问卷调查、作品互评等方式对学生进行多元评价，提高学生线上学习效率，保障学生线上学习效果。……
