| 目的 本研究采用科学知识图谱的方法，系统地分析了过去50年来综合评价基于问题的学习（problem-based learning，PBL）研究领域的文献，探讨PBL发展规律及其发展中重要的时间和文献。方法 检索Web of Science（WOS）引文数据库1970至2019年关于PBL研究的所有经同行评议的期刊文章。运用R软件中科学知识图谱分析Bibliometrix包进行如下分析：PBL的文献年增长规律、文献累积增长规律、文献被引情况及排名前30的重要文献。据此探索PBL研究领域发展规律、重要时间和文献节点。结果 经过文献清洗，最终纳入2 401篇文献进行分析。通过分析发现：按照学科发展规律，PBL研究经历了3个时期，即PBL研究诞生期（时期Ⅰ）、PBL研究发展初期（时期Ⅱ）和PBL研究大发展期（时期Ⅲ），目前正处于大发展期；在发展过程中，1983年、1986年、1993年、2003年、2005年、2007年、2011年、2012年和2014年成为了重要的研究时间节点，出现了5篇推动PBL发展的重要文献（ALBANESE MA，1993，ACAD MED；VERNON DTA，1993，ACAD MED；NORMAN GR，1992，ACAD MED；BARROWS HS，1986，MED EDUC；HMELO-SILVER CE，2004，EDUC PSYCHOL REV）。结论 目前，PBL的理论和方法得到了完善，正处于大发展期，也是运用推广的重要时期；PBL已成为目前国际上教授和学习临床技能或其他实践性强的学科的重要方法。 |

| Objective To apply knowledge maps to systematically evaluate problem-based learning (PBL) literatures from the past 50 years, so as to explore the law of development and related important documents. Methods All peer-reviewed studies were retrieved from Web of Science (WOS) Citation Database on PBL of the year from 1970 to 2019. Bibliometrix package of R was used to analyze following items: annual growth law of PBL literature, literature cumulative growth law, literature citation status and top 30 important documents. Based on the results, the law of development of PBL research, important literatures and time nodes was analyzed. Results After literature cleaning, 2 401 documents were finally included into the analysis. The analysis revealed that: in accordance with the law of development disciplines, PBL study experienced three periods, early birth (Period Ⅰ), PBL study early development (Period Ⅱ) and PBL large-scale development (Period Ⅲ). Now PBL is currently in a period of large-scale development. In the development process, 1983, 1986, 1993, 2003, 2005, 2007, 2011, 2012 and 2014 has become important research time nodes, and there have been five important documents promoting PBL development (ALBANESE MA, 1993, ACAD MED; VERNON DTA, 1993, ACAD MED; NORMAN GR, 1992, ACAD MED; BARROWS HS, 1986, MED EDUC; HMELO-SILVER CE, 2004, EDUC PSYCHOL REV). Conclusion Nowadays, PBL theory and method has been perfected, which has been developed significantly, and it's an important period of application and promotion. The PBL has become an important method to cultivate clinical skills or other disciplines with strong practicality. |
