“昆虫生态及预测预报”在线教学改革与实践

“昆虫生态及预测预报”是高等农业院校植物保护专业的一门选修课。由于其涉及大量抽象的概念，同时难以开展实验教学，一直是一门较难学习的课程。新冠肺炎疫情期间，在课堂教学向线上教学转换的过程中，通过把教学章节破碎重组，将教学内容分割为20分钟时长的小段，使其适合在线教学。再辅以MOOC和在线讨论问答的形式，增加教学的趣味性和互动性，从而提高学生的学习热情。同时开展计算机模拟实验，通过在线屏幕投送和会议讨论的形式，使学生使用教师提供的数据在各自客户端建模，计算实验结果后撰写实验报告。通过直播理论教学和互动实验教学相结合的线上教学形式，学生经历了从理论到实践的双重学习过程，从而提高了解决实际问题的能力，且学生积极性高，教学节奏顺畅，教学效果良好。

Study on the Online Teaching Reform and Practice of Insect Ecology and Forecast Course

Insect Ecology and Forecast Course is a professional elective course of plant protection major in agricultural universities.It has always been a difficult course to learn,because not only it involves a large number of abstract concepts,but also it is very hard to carry out experimental teaching.During the pandemic outbreak,and in the process of the transformation from classroom teaching to online teaching,the chapters were divided and reorganized into 20-minute segments to make it suitable for online teaching.With the help of MOOC and online discussion,we can make the teaching more interesting and increase the interaction in the teaching process in order to improve students’learning enthusiasm.At the same time,the computer simulation experiment is carried out.Through the forms of online screen delivery and meeting discussion,the students can use the data provided by teachers to model in their respective clients,calculate the experimental results and write experimental reports.Through the online teaching combining live broadcast theory teaching and interactive experimental teaching,the students have experienced the dual learning process of classroom theory knowledge learning and practice learning,which can improve their ability to solve practical problems.After the reform,students become more enthusiastic in learning,the teaching process becomes more smooth,and good teaching effect has been achieved.
