【中文摘要】：
文章对《学习科学杂志》创刊27年来发表的445篇论文分阶段（1991—2000年、2001—2009年、2010—2017年）进行主题概念图分析，以此来探究学习科学领域中关键概念的演化与主题的变迁。学习科学在1991—2000年间围绕教学展开，侧重分析知识表征、概念转变、建模学习环境、智能导师系统等；在2001—2009年间以学习者为中心，聚焦学习的认知过程、情境与参与；在2010—2017年转变为关注学习理论模型、学习过程、话语、社会性学习、学习参与。研究表明，需要加强对学习情境化与学习科学化的辨析；理解模型与工具等重要概念的演化，以及厘清环境、场景、情境等重要概念的异同，来帮助教育决策者、实践者在学习科学研究的基础上推动教育改革。
【英文摘要】：
This paper analyzes the concepts and themes in 445 papers published in 27 years since the publication of the Journal of Learning Sciences in phases (from 1991 to 2000, from 2001 to 2009, and from 2010 to 2017) to explore the evolution of key concepts and the change of themes in learning sciences. From 1991 to 2000, learning sciences focused on analyzing knowledge representation, concept transformation, modeling learning environment and intelligent tutor system. From 2001 to 2009, it focused on the cognitive process, context and engagement of learning. While from 2010 to 2017, the focuses of learning sciences turned to learning theoretical models, learning process, discourse, social learning and learning participation. The study indicates that in order to help policymakers and practitioners to promote educational reform based on the research of learning sciences, it is necessary to strengthen the discrimination of learning in context and scientific learning, to understand the evolution of important concepts such as models and tools, and to clarify the similarities and differences of important concepts such as environment, scene and context as well.
