PBL在消化内科见习课中的应用

目的七年制医学生消化内科见习课中引入以问题为基础的学习（Problem—based learning，PBL），探讨其实践方法和教学效果。方法对七年制医学生分别进行传统教学（胃肠道疾病）和PBL教学（肝胆疾病），通过理论考核和问卷调查的方法评价教学效果。结果①理论考试成绩差异无统计学意义（P〉0．05）；②PBL教学受到学生的普遍欢迎，提高了学生学习积极性，学生在自学能力、归纳总结能力以及临床思维能力培养等方面获益匪浅。结论在消化内科见习课中开展PBL教学是可行的，有助于提高教学效果，应在今后的工作中加以推广。

Application of PBL in teaching of gastrointestinal disease during internal medical probation

Objective To explore the practical method and teaching effect of problem-based learning （PBL） pattern in teaching of gastrointestinal disease for seven-year-program students during their internal medical probation. Methods The traditional pattern （ gastrointestinal diseases） and PBL pattern （hepatobiliary diseases） were applied in these students to assess the teaching effects by exam scores and questionnaire. Results ①There was no significant difference between traditional training and PBL by exam scores （ P 〉 0.05 ）. ②The PBL approach was widely accepted by students, which could contribute to the improvement of their learning motivation. It developed skills, including serf-di- rected learning, summarizing, and clinical thinking capability and so on. Conclusion The PBL approach is a practical learning strategy that can improve the teaching effect; therefore it should be wildly practiced in future works.
