微课在农科类专业试验统计学教学中的应用

Application of Micro-lecture in Teaching of Experimental Statistics in Agricultural Specialties

微课是针对单一知识点授课,通过简短的视频或音频等多媒体形式录制并结合一定的学习任务而形成的一种教学方式。笔者分析了目前农科类专业试验统计学的教学现状,认为试验统计学教学时数少,内容庞杂,滞后于实践需求,且学生学习兴趣不高。介绍了近年来各大高校试验统计学尝试运用的案例教学法、答疑法、自学指示法、讨论教学法。在此基础上,就微课应用于试验统计学教学展开探索,并以概率统计中正态分布的讲解为例分析微课教学的内容与设计过程,同时总结了微课应用于实验统计学教学需要注意的问题,以期提高课程教学质量与教学效果。

Micro-lecture is a teaching method that teachers teach a single knowledge point to students by multimedia such as a short video and audio frequency. In this study,the present teaching situation of experimental statistics in agricultural specialties was analyzed. It is found that its teaching hours are few; its teaching content is multifarious and disorderly and lags behind practical needs; students＇ learning interest is not high. Afterwards,some teaching methods of experimental statistics applied in colleges and universities in recent years,such as the case method,method of answering questions,self-study indication method,and discussion method,were introduced. To explore the application of micro-lecture in the teaching of experimental statistics,the content and design process of micro-lecture teaching were analyzed through the explanation of normal distribution in probability statistics. Meanwhile,problems that should be noticed in the application of micro-lecture in the teaching of experimental statistics were summarized to improve the teaching quality and effect of the course.
