摘    要：普通昆虫学是高等农科院校植物保护学本科专业的必修课程，同时是农学、园艺、森林保护、动植物检疫等专业的基础课程。单一的线上或线下教学模式都有各自的缺点，无法达到普通昆虫学课程的最优教学效果。本研究以“智慧树”网络教育平台为载体，阐述在普通昆虫学课程中将网络平台资源与传统线下教学手段融合，学生在课前进行线上课程自学，完成“智慧树”平台教学视频观看，提出线上学习疑惑，教师在线下授课过程中复习巩固线上课程学习的主要内容，针对重点与难点内容进行答疑解惑，灵活运用问题式、讨论式或小组汇报式的教学方法，在课后开展线上测验与讨论，建立合理的线上、线下混合考核体系，从而实现该课程线上与线下混合教学模式的改革，提高教育教学效果。

Abstract： General Entomology is a compulsory course for the undergraduates majoring in plant protection in agricultural colleges and universities， as well as a basic course for undergraduates majoring in agriculture， horticulture， forest protection，and animal and plant quarantine. Both the traditional offline teaching and the single online teaching have certain disadvantages， which cannot achieve the best teaching effectiveness. This study explored the teaching reform of General Entomology based on the Intelligent-Tree platform. The resources from the network platform and traditional offline teaching were integrated in the course of General Entomology. Students could carry out online course self-studies before class， watch teaching videos on the Intelligent-Tree platform， and propose questions of online studies. Teachers could help students to review the main contents of online course， answer questions for important and difficult course contents， flexibly use problem-based， discussion-based or group presentation-based teaching methods， conduct online tests and discussion after class， and establish a reasonable online-offline blended assessment system.These measures could realize the reform of online-offline blended teaching mode and improvement of the teaching efficiency of this course.

普通昆蟲学是高等农科院校植物保护学本科专业的必修课程[1-2]，同时是农学、园艺、森林保护、动植物检疫等专业的基础课程[3-5]。课程内容主要包括昆虫的外部形态、昆虫的内部结构与生理学、昆虫生物学、昆虫系统学和昆虫生态学五大部分[6]。该课程内容繁多、涉及面广、理解记忆难度大，具体表现为昆虫形态名称枯燥难记、生物学概念容易混淆、生理与生态内容抽象难懂、分类特征细微难认。传统的课堂教学大多以线下教学模式采用“板书+ PPT展示”方式授课，在这种单一的授课模式下，学生缺乏学习的热情和主动性，经常出现教师在讲台上激情澎湃授课，而学生注意力却不集中的现象，课堂氛围比较沉闷，学生与教师之间的课堂互动积极性低。……
