“虚实结合”的线上线下混合教学模式在牙体牙髓病实验教学中应用研究

Research on the application of a blended learning mode of online and offline "virtual and real combination" in experimental teaching of dental and pulp disease course

目的 探讨融合微课和虚拟仿真实验的“虚实结合”的线上线下混合教学模式在牙体牙髓病实验教学中的效果。方法 选择四川大学华西口腔医学院口腔医学专业2019级全日制在读本科生96名,针对牙体牙髓病实验教学,利用“虚拟仿真实验+微课”线上平台安排同学自主学习后,进行线下教学,课程结束后进行问卷调查。结果 问卷发放100份,回收96份。结果显示,大部分的学生(60.4%,58/96)认为线上融合课程模式利于自主学习;多数同学支持其利于自主控制学习进度(67.7%,65/96)和利用碎片化时间(64.6%,62/96);快速掌握流程(71.9%,69/96)、加深概念理解(69.8%,67/96)被认为是该模式利于课堂学习的重要因素。结论 “虚实结合”的线上线下混合教学模式将理论学习和实践操作紧密结合,受到多数学生支持,能促进学生自主学习能力,提高了实验课学习效果。

Objective To investigate the teaching effect of a blended online and offline learning mode that combines micro-lectures and virtual simulation experiment in the preclinical course of dentistry and endodontics.Methods Totally96 full-time undergraduates majoring in stomatology,Grade 2019,in West China College of Stomatology of Sichuan University were selected.A blended teaching model was adopted,with students first learning independently using an "online virtual simulation experiment + micro-lecture" platform,followed by offline classroom teaching.After the course,a teaching evaluation questionnaire was distributed to evaluate the teaching effect.Results 100 questionnaires were distributed and 96 were returned.Most of the students(60.4%,58/96)believed that the online blended mode was conducive to autonomous learning.Most students believed that it enabled them control the learning pace in a given timeframe(67.7%,65/96)and have the ability to learn autonomously during fragmented time(64.6%,62/96).The rapid mastery of the operation process(71.9%,69/96)and the deepening of the understanding of abstract concepts(69.8%,67/96)were the main factors in promoting classroom learning.Conclusion This mode of online and offline teaching combines theoretical learning with practical operation,and it is supported by most students which can also promote the ability of autonomous learning and improve the learning effect of laboratory courses.
