The current review employed bibliometric review methods to analyze 14,130 Scopus-indexed documents on problem-based learning published from 1972 through the end of 2019. The goals of the review were to describe the landscape and analyze the evolution of topical foci of interdisciplinary research on PBL over the past five decades. The review identified the accumulation of a substantial interdisciplinary corpus of research on PBL that is significantly larger than the literature on other approaches to active learning. The growth trajectory of the literature on PBL started out “low and flat” during the 1970s and 1980s but steadily gained momentum in subsequent decades, with 58% of the PBL literature published between 2010 and 2019. PBL has achieved an impressive scope of global research over the past 45 years, with a significant number of studies published from emerging regions of the world, especially during the past decade. While a long-term body of research has accumulated on the learning outcomes of PBL, the research front has begun to shift towards the study of self-directed learning, student satisfaction, self-efficacy, critical thinking, and cooperation. Research and practice challenges identified in the review focus on establishing the scope of use and efficacy of PBL across different cultural contexts and more systematically summarizing and synthesizing the use of PBL outside of the health professions.

跟踪基于问题的学习知识库的演变：文献计量学评论，1972-2019

本次审查采用文献计量审查方法，分析了从 1972 年到 2019 年底发表的 14,130 份 Scopus 索引的基于问题的学习的文件。审查的目的是描述景观并分析 PBL 跨学科研究的主题焦点的演变在过去的五年里。该评论确定了 PBL 研究的大量跨学科研究语料库的积累，该语料库明显大于其他主动学习方法的文献。PBL 文献的增长轨迹在 1970 年代和 1980 年代开始“低而平稳”，但在随后的几十年中稳步增长，58% 的 PBL 文献在 2010 年至 2019 年间发表。PBL 在全球研究领域取得了令人瞩目的成就在过去的 45 年里，世界新兴地区发表了大量研究，尤其是在过去十年中。在 PBL 学习成果的长期研究积累的同时，研究前沿已经开始转向自主学习、学生满意度、自我效能、批判性思维和合作的研究。审查中确定的研究和实践挑战侧重于确定 PBL 在不同文化背景下的使用范围和功效，以及更系统地总结和综合卫生专业之外的 PBL 使用。学生满意度、自我效能、批判性思维和合作。审查中确定的研究和实践挑战侧重于确定 PBL 在不同文化背景下的使用范围和功效，以及更系统地总结和综合卫生专业之外的 PBL 使用。学生满意度、自我效能、批判性思维和合作。审查中确定的研究和实践挑战侧重于确定 PBL 在不同文化背景下的使用范围和功效，以及更系统地总结和综合卫生专业之外的 PBL 使用。
