摘要

目的　探讨以问题为基础的学习（problem-based learning， PBL）在医学高职高专《生物化学》课程教学中的应用效果。方法　对2011级医学检验专业128名学生进行分组教学，实验组（64人）采用PBL教学，对照组（64人）采用传统的课堂讲授法。对照组中教师根据课程标准要求进行教学设计，结合多媒体课件，讲解各章节的基本内容，配套课堂练习和课后作业。实验组教学依托学校的教学平台建设生物化学教学网站开展PBL教学。教学过程为学生分组———选取合适案例———查阅资料———小组讨论———教师总结。课程结束后对2组学生进行理论测试，对实验组进行教学问卷调查。2组测试平均成绩进行独立样本t检验。结果　实验组的平均成绩（83.56±11.87）高于对照组（76.15±12.48），差异有统计学意义。问卷调查显示，90.0％以上的学生对PBL教学法感兴趣，认为该教学法能提高学习积极性、自主学习能力和综合分析能力。结论　PBL能明显提高生物化学教学效果，培养学生的综合能力，值得深入研究和推广

Abstract

Objective　To explore the effect of problem-based learning （PBL） in biochemistry teaching in medical college. Methods　Totally 128 students （2011 grade） of medical laboratory major were derived into experiment group （n=64） and control group （n=64）. Lecture-based learning （LBL） was used in control group and PBL was used in experiment group.In control group， teachers did teaching design according to the needs of curriculum standards， employed multimedia courseware， explained the basic content of each chapter， class exercises and homework after class. In experimental group， PBL was conducted through establishing biochemistry teaching website based on school's teaching platform. Teach-ing process in experiment group included： grouping-selecting appropriate cases-consulting data-group discussing-summarizing by teachers. Theory test was carried out after the course and questionnaire was conducted for students in experiment group. Data were analyzed using the independent sample t test. Results　Average test scores were higher in PBL group than in traditional group， with statistically signif-icant differences[（83.15±11.87） vs. （76.15±12.48）]. Questionnaire survey showed that more than 90.0% students in experiment group were interested in the PBL teaching method and thought that the PBL teach-ing method can enhance the enthu-siasm of learning， independent learning ability and comprehensive analysis ability. Conclusions　PBL teaching method can improve the quality and the effect of biochemi-stry teaching and culture students' comprehensive ability. It is worthy of further study and popularization.
