The aim of this paper is to objectively present the development and trend of international MOOC research. Metadata taken from 660 literature records is used to visualize the state of MOOC research. The records were published between 2008 and 2018, and Citespace software is employed to visualize key data about the research contained on the SCI and SSCI platform. It has the following findings. First, since 2012, the number of international MOOC research papers and cited frequency has shown an upward trend. The research force was mainly concentrated in North America, Europe and Asia, and the publishing institutions were mainly concentrated in Universities of various countries, and formed a more obvious international cooperation network. Second, journals such as ≪INT REV RES OPEN DIS≫ and ≪COMPUTERS & EDUCATION≫ are the foundational literatures of MOOC research. George Siemens, Stephen Downes, John Daniel and others have made important contributions to the foundation research of MOOC. Third, Breslow, Liyanagunawardena et al. were cited more frequently and formed eight research clusters such as teaching interaction, relativism/behaviorism theory, individualized learning and diversified education. Fourth, distance education, online learning, learning situation analysis, curriculum construction and platform construction are the hot topics of international MOOC research in the recent decade. Fifth, the development of international MOOC has spread to various disciplines and promoted the interdisciplinary research of environment, biology, medicine, philosophy, psychology and other disciplines.

2008-2018国际MOOC研究的轨迹、热点与前沿——基于SCI和SSCI的科学计量分析

本文旨在客观地介绍国际MOOC研究的发展和趋势。从 660 篇文献记录中提取的元数据用于可视化 MOOC 研究的状态。这些记录发表于 2008 年至 2018 年间，并使用 Citespace 软件将 SCI 和 SSCI 平台上包含的研究的关键数据可视化。它有以下发现。一是2012年以来，国际MOOC研究论文数量和被引频次呈上升趋势。研究力量主要集中在北美、欧洲和亚洲，出版机构主要集中在各国大学，形成了较为明显的国际合作网络。二、期刊如≪INT REV RES OPEN DIS≫和≪计算机与教育≫是MOOC研究的基础文献。George Siemens、Stephen Downes、John Daniel等人为MOOC的基础研究做出了重要贡献。三、布雷斯洛，利亚纳古纳瓦德纳等。被引用频率较高，形成了教学互动、相对主义/行为主义理论、个性化学习、多元化教育等8个研究集群。第四，远程教育、在线学习、学习态势分析、课程建设和平台建设是近十年国际MOOC研究的热点。五是国际MOOC的发展向各个学科蔓延，促进了环境、生物学、医学、哲学、心理学等学科的交叉研究。
