骨科理论教学中视频多媒体资源库的建立及应用评价

Establishment and Application Evaluation of a Video Multimedia Resource Library in Orthopedic Theory Teaching

目的:建立用于骨科理论教学的视频多媒体资源库并进行应用评价。方法:按照教学大纲和要求分析梳理相关知识点,在教育公共平台筛选视频资源与之相匹配并形成视频资源库供教学使用;以2021-2022临床医学本科学生为研究对象,将2022年使用资源库教学的33名学生设为试验组,2021年未使用资源库教学的34名学生设为对照组,分别以问卷和理论考核的形式评价应用效果。结果:共整理出适合通过视频片段来展示或配合老师讲解的知识点31条,平均每节3.1条,以此建立的资源库储存视频资源68条,时长共计约206分钟,平均每个知识点匹配约2.2条;使用中授课老师和试验组学生问卷调查的满意率和有效率均为100%;理论考核成绩试验组学生的优秀率和良好率均高于对照组。结论:建立和使用骨科理论教学视频资源库有助于学生提高学习兴趣和成绩,也有助于教师教学课件的准备,可为提高教学水平创造条件。

Objective:To establish a video multimedia resource library for orthopedic theory teaching and evaluate its application.Methods:Relevant knowledge points were analyzed and sorted according to the teaching syllabus and requirements.Video resources matching these points were selected from public education platforms to form a video resource library for teaching use.The study subjects were clinical medicine undergraduate students from 2021-2022.The 33 students taught using the resource library in 2022 were designated as the experimental group,while the 34 students taught without it in 2021 served as the control group.The application effect was evaluated through questionnaires and theoretical assessments.Results:A total of 31 knowledge points suitable for video demonstration or supplementary teaching were identified,averaging 3.1 points per lecture.The established resource library stored 68 video resources with a total duration of approximately 206 minutes,averaging about 2.2 videos per knowledge point.The satisfaction and effectiveness rates of the teaching staff and experimental group students were both 100%in the questionnaire survey.The experimental group students also showed higher excellent and good rates in theoretical assessments compared to the control group.Conclusion:The establishment and use of the orthopedic theory teaching video resource library help improve students'learning interest and performance and assist teachers in preparing teaching materials,thereby creating conditions for enhancing teaching quality.
