临床分子生物学检验教学中的PBL创新实践及其推广分析

目的　在《临床分子生物学检验》课程中实施以问题为基础的学习（problem-based learn-ing，PBL）创新性实践，并对PBL教学推广情况进行调查分析。方法　以某医学院校医学检验技术专业学生（137人）为研究对象，以演讲比赛为主要方式进行PBL教学创新实践，教学成果以视频形式通过微信进行网络分享与推广；并通过微型问卷对该专业学生（335人）进行PBL教学推广调查，对调查结果进行统计。结果　基于演讲比赛的改良PBL可以使学生主动融入课堂教学，学生对知识的理解也更加深刻，《临床分子生物学检验》教学达到预期效果。问卷调查显示，现阶段PBL在检验专业学生当中的影响并不广泛，今后尚有更大空间推广此类教学方法。尽管传统教学在部分学生心目中占有一席之地（43.9%，147人）；不过新颖有趣、丰富多彩的PBL创新教学，更符合医学检验专业学生的期望，接受度最高（49.6%，166人）。结论　采用演讲比赛形式的PBL创新实践教学，可以加强学生对知识的掌握与灵活运用，值得推广；今后教师可以在传统教学基础上，逐步融入新型PBL，让学生在轻松与主动的氛围中高效率学习。

Innovative practice and popularization analysis of problem-based learning in the teaching of clinical molecular biology testing

Objective To carry out innovative practice as well as questionnaire survey and conduct promotion analysis of clinical molecular biology testing based on problem-based learning (PBL). Methods 137 Students of medical laboratory technology discipline were chosen as subjects to conduct the innovative practice of PBL method. The teaching results were shared and promoted by video online through WeChat. Micro-questionnaire was conducted in 335 students, and the results of the survey were statistically analyzed. Result The improved PBL teaching based on speech contest can boost students to integrate into classroom teaching actively in which they had a better understanding of the knowledge so that the expected teaching quality of clinical molecular biology testing was achieved effectively. Questionnaire showed that the impact of PBL teaching method on students was not extensive currently, indicating that there was still more space to promoting such teaching methods. Although traditional teaching methods still held a place in students'' minds (43.9%, 147 cases), the innovative teaching of PBL, which is novel, interesting and colorful, is more in line with the expectations of medical laboratory students in the new era and has the highest acceptance (49.6%, 166 cases). Conclusion The innovative practice of PBL teaching based on speech contest can achieve the purpose of strengthening students'' knowledge acquisition and flexibility in the practical use of knowledge, which is worthy of promoting. Teachers could gradually integrate the new PBL teaching model into the tradi-tional teaching methods in the future, making students study efficiently in a relaxed and active atmosphere
