混合式教学模式是传统课堂教学与数字化网络教学相结合的教学模式,近年来广泛应用于医学专业课程教学。本研究以长治医学院2019级五年制临床医学专业学生的生物化学与分子生物学课程为例,阐述了混合式教学模式在生物化学与分子生物学课程中的设计和实施过程,通过学生在线微课视频和作业完成情况、在线篇章测试成绩、问卷调查结果等评价教学效果。结果显示,95.3%(244/256)以上的学生完成了在线微课视频观看、89.8%(230/256)以上的学生提交了章节作业且作业平均成绩较高(>91.7分);学生在生物分子的结构与功能、物质代谢、遗传信息传递等3大篇章测试平均分均>90.0分。91.4%(234/256)的学生认为教师课堂讲授对学习非常有效果;82.0%(210/256)的学生认为线上线下师生互动交流和课堂讨论、84.4%(216/256)的学生认为线上完成章节作业与篇章测试非常有效果。混合式教学模式有助于提高学生的学习成绩,学生参与较为积极,得到了学生认可。

Blended teaching mode which combines traditional classroom teaching with digital network technology has been widely used in the teaching of medical courses in recent years. The study on application of blended teaching mode in biochemistry and molecular biology was carried out among undergraduates of five-year clinical medicine program enrolled in 2019 at Changzhi Medical College. The teaching effect was evaluated by the process of students' online learning of micro-lesson video and homework,test score and results of questionnaire survey. The results showed that more than 95.3%(244/256)of the students had completed online micro-lesson videos' watching, more than 89.8%(230/256)of the students submitted their chapter assignments with a high average score(>91.7 points). The three parts of the course were tested, including the structure and function of biomolecules,substance metabolism and genetic information transmission, the average score of each test was >90.0 points, and 91.4%(234/256)of the students believed that classroom teaching was very effective in course learning; Results also showed that 82.0%(210/256)believed that online and offline interaction between teachers and students as well as classroom discussion helped to master the learning content, and as 84.4%(216/256)of the students thought that completing the chapter assignments and part tests online would help their learning. Blended teaching improves students' learning outcomes and students' participation is more active, which has been recognized by students.
