基础知识与PBL学习过程对医学生能力提高的不同影响

Different effects of basic medical knowledge and PBL on comprehensive abilities of undergraduate students

目的分析基础知识掌握程度与PBL学习过程对医学生能力提高的不同影响,为医学教育的教学方法改革提供依据。方法选取以乙型肝炎为主题的医学微生物学科背景案例,以医学微生物学成绩、PBL平时成绩分组,比较案例相关内容考核成绩的差异。结果医学微生物学成绩高的学生,案例考试中情境式分析型单选题成绩高(P<0.05);PBL平时成绩高的学生,案例考试中情境式简答题成绩高(P<0.05)。结论基础学科知识的掌握程度与PBL讨论过程对医学生知识与能力的提高都有重要的意义。

Objective To reveal the different effects of basic medical knowledge and PBL on comprehensive abilities of undergraduate student,and provide evidence for medical education reform.Methods Choose one case aimed at Hepatitis B virus （HBV）,compare the scores of Microbiology,PBL scores and scores of final exam on case.Results Students with higher Microbiology scores got higher scores on scenario-related multiple choice question （MCQ-S） compared with students with lower Microbiology scores （P ＜ 0.05）.Students with higher PBL scores got higher scores on short answer question （SAQ） compared with lower PBL scores （P ＜ 0.05）.Conclusions Basic medical knowledge and PBL have different effects on comprehensive abilities of undergraduate students.
