“放射测量与防护”课程线上线下混合式教学实践

Practice of Online and Offline Mixed Teaching of“Radiation Measurement and Protection”Course

线上线下混合式教学成为高校教学改革和发展的主要趋势。该文主要对“放射测量与防护”课程进行线下授课与线上同步讨论和考核,通过课前准备、课中授课和课后复习几方面说明混合式教学相互依靠、相辅相成的过程。线上课程中增设课前预习任务、课中知识点讨论任务、课后作业、在线答疑辅导及考勤率统计等内容,并实时生成每名学生的学习分析表,便于教师及时了解学生的学习情况。通过线上评价、线下评价和最后的期末考核,重点评价学生的各个学习过程,从而有效调动学生学习的积极性和主动性。通过近几年的线上线下混合式教学实践,教学成效显著提高。

Online and offline mixed teaching is increasingly becoming the main trend of teaching reform and development in colleges and universities.This paper focuses on the offline teaching and online synchronous discussion and assessment for the course of“Radiation Measurement and Protection”.Through pre-class preparation,in-class teaching and after-class review,this paper explains the process of mutual dependence and complementarity of mixed teaching.In the online course,students’pre-class preview task,in-class knowledge point discussion task,after-school homework,online guidance and attendance statistics are added,and the learning analysis table of each student is generated in real time,so that teachers can understand students’learning situation in time.Through the three criteria of online evaluation,offline evaluation and the final-examination,teachers can focus on evaluating students’learning processes,thus effectively mobilizing students’enthusiasm and initiative in learning.Through the practice of blended online and offline teaching in recent years,the teaching effectiveness has been significantly improved.
