摘要
目的通过开展基于PACS的翻转课堂教学,旨在能够创设一个以学生为中心、高效和愉悦的医学影像教学模式。方法选择61名中国医科大学医学影像专业学生,随机分为6组,进行8学时的骨肌影像翻转课堂教学。整个教学分四个阶段:(1)课前准备阶段。学生通过课前学习录像和查阅资料完成检测题;(2)课上检测阶段。学生分组回答课前作业,教师进行评价、分析并给出正确答案;(3)讨论阶段。学生主动提出自己的学习问题,由教师进行回答;(4)拓展阶段。学生通过PACS在线分析病例。课后采用问卷形式对全体学生和3名授课教师进行授课效果的调查。结果通过翻转课堂教学,学生自学能力和学习兴趣得到提高,课堂气氛活跃,分析和解决问题能力得到锻炼;结合PACS翻转课堂教学扩展了知识的深度和广度,使学生在影像和临床知识的延伸以及学科交叉内容方面都有了一定程度的认识。结论基于PACS的医学影像翻转课堂,能够促进教与学的目标在课堂上有效的统一,培养影像专业学生的初步临床实践能力和创新意识,是一种科学有效的教学模式。
Objective To create a student-centered, effective, interactive teaching model for a medical imaging course, based on PACS flipped classroom technique. Methods A group of 61 students special- izing in medical imaging from China Medical University were randomly divided into 6 groups. During a skeletal muscle imaging course, they participated in a total of 8 flipped teaching classes. The whole curriculum included four stages： 1. preparation; 2. examination l 3. discussion; 4. development. The preparation stage included a self-study portion that featured videos and questions. The examination stage was a student-led group discussion of the assigned homework in which the teacher made com- ments and offered guidance. The discussion stage was a question-and-answer period where the teacher addressed student issues and concerns. The development stage included online case analysis through PACS. After completion of the eighth class, each participant completed a questionnaire about effec- tiveness of the teaching experience. Results Students who participated in the study commented that this kind of learning strengthened their ability to learn independently and that the flipped model heightened interest during class. There was a noticeable improvement in the class atmosphere being more active and students had more opportunities to analyze and solve problems. Flipped classroom combined with PACS extended the depth and breadth of student knowledge and also resulted in a marked improvement in students＇ imaging, clinical and interdisciplinary knowledge. Conclusion Flipped classroom based on PACS can promote the attainment of teaching and learning objectives. It can be used in the classroom to train students during preliminary clinical practice. Flipped classroom teaching is a scientific and effective teaching model.
