摘　　要：目的:比较传统教学方式、PBL教学、生物力学模拟情景+PBL教学在产科分娩机制临床教学中的应用效果,评估生物力学模拟情景+PBL教学方法的教学效果。方法:本研究共纳入山东大学临床医学院“5+3学制”学生42名,其中男性23名,女性19名。采用序贯教学方法,即对纳入研究的42名学生依次给予传统教学、PBL教学以及生物力学模拟情景+PBL教学,每种教学方式结束后随即给予随堂测试,测试内容分为记忆性问题及理解性问题,并在整体教学结束后给予教学质量问卷调查以评估教学效果。结果:(1)PBL教学与传统教学相比,无论是对记忆性问题还是理解性问题成绩都有显著提升(P<0.01);生物力学模拟情景+PBL教学与PBL教学相比,对于记忆性问题成绩无明显改善(P>0.05),但可有效提升理解性问题成绩(P<0.01)。(2)教学质量问卷结果显示:学生对于分娩机制理解掌握的难点主要集中在内旋转(58%)、衔接(47%)以及复位外旋转(42%),主要原因是分娩过程不可直视,抽象、难以理解(68%),经生物力学模拟情景+PBL教学后,学生对分娩机制各部分的掌握均有提升。此外,在生物力学模拟情景+PBL教学中,学生们认为其学习态度、学习效率以及处理临床问题能力均有显著提高,且在教学活动中与教师有良好的互动。结论:PBL教学与传统教学方式相比,生物力学模拟情景教学可以有效改善理解性问题成绩,从而突破分娩机制理解难点,同时可以有效改善学生学习态度、学习效率及临床综合处理能力,师生间互动也更为活跃。and difficult to understand(68%).After biomechanical simulation scenario+PBL teaching,students'grasp of all parts of the delivery mechanism was improved.In addition,the students believed that their learning attitude,learning efficiency and ability to deal with clinical problems were significantly improved in the biomechanics simulation scenario+PBL teaching mode,and they had a good interaction with teachers in teaching activities.Conclusion:PBL teaching significantly improves both memory and comprehension scores over traditional methods.Biomechanics simulation+PBL further enhances comprehension and helps break through the difficulties in understanding the delivery mechanism.This method also positively impacts students'learning attitudes,efficiency,and clinical problem-solving abilities,fostering better teacher-student interaction.
