摘要: 目的 前瞻性设计并评估网络录播课程与在线答疑相结合在研究生医学影像学课程教学中的效果,拟为未来影像医学网上课程提供更多的经验。方法 纳入2020年春季学期课程学员19人,以在线问卷调查收集各堂课程前知识技能掌握程度自我评估、各堂课程后自我评估、答疑环节参与程度、现场\在线\录播+答疑课程主观评价,收集数据并进行分析比较。结果 全部16节课程学习后的知识技能掌握程度都显著高于课程前(P<0.01),学生客观考试平均分数为44.2±7.0,学生在答疑环节的参与度平均分数为3.79±0.92,答疑参与度与最终客观题目考试分数之间没有显著相关性。学生对答疑环节必要性的评价平均得分4.47±0.90,学生对传统课堂的主观感受平均分高于远程虚拟课堂,但是两者之间没有统计学意义。结论 医学影像学录播课程结合在线答疑的网络课堂形式对于提高学员相应知识技能是有明显效果的,线上答疑环节可以提高学生的参与度,调动学习积极性。

Abstract: Objective To prospectively design and followed by evaluation on the effect of the combination of recorded lectures with online question and answer(Q & A) in graduate course of medical imaging, so as to provide more experience for future online medical imaging courses. Methods A total of 19 students recruited in the 2020 spring semester course were included. An online questionnaire was used to collect the results of self-assessment on knowledge and skill learning before and after each lecture, participation rate of Q & A activity. Results The knowledge and skills mastery level after learning every 16 lectures was significantly higher than that before the lecture. The average score of students in the Objective test was 44.2±7.0 and the average score of students' participation in the Q & A session was 3.79±0.92. There is no significant correlation between test scores and the participation in Q & A. The average score of students' evaluation of the necessity about the Q & A activity is 4.47±0.90. The average score of students' subjective feelings of traditional classrooms is higher than that of remote virtual classrooms, but the difference is not statistically. Conclusions Recorded lectures plus online Q & A in graduate course of medical imaging has significantly improved students' learning outcomes on knowledge and skill. Online Q & A following the course can increase students' participation and enhance their learning motivation.
