中国临床专业学生PBL教学临床实习效果分析

Effectiveness of Problem-based Learning in Clinical Students:A Meta-analysis

目的系统评价PBL教学法对我国临床专业学生临床实习效果的影响。方法计算机检索CNKI(1994～2008)、VIP(1989～2008)、万方数据库等,收集国内有关PBL教学法对比LBL教学法对临床专业学生临床实习效果的随机对照研究。在严格评价质量的基础上,使用RevMan5.0软件进行数据分析。结果最终纳入7篇研究。Meta分析结果显示:现有研究质量均不高,且异质性较大,数据无法合并,仅能采用描述性分析。PBL教学法与LBL教学法比较,有提高临床专业综合分析能力、自学能力、查阅文献能力、创新能力的趋势。结论PBL教学法相对于LBL教学法,可能会提高临床专业的教学效果,但由于纳入研究质量差异较大,有必要开展设计更严谨的随机对照试验来验证这种趋势。

Objective To assess the affect of problem-based learning （PBL） versus literature based learning （LBL） in clinical medicine students. Methods Computer retrieval was conducted to search for controlled studies comparing PBL with LBL. The quality of included studies was critically evaluated and data was analyzed by using The Cochrane Collaboration＇s RevMan 5.0 software. Results Finally 11 articles were included in the review, but most of them were of low quality.There are clinical heterogeneity between different studis which cause descriptive results. The PBL tended to be superior to LBL in the analysis-skill, self-directed learning skill, data-searching skill, and original skill. Conclusion PBL tends to be associated with better learning results among clinical medicine students compared with LBL methods. We need large-scale, randomized controlled trials of higher quality to confirm this.
