中学地理单元教学研究热点与展望——基于CiteSpace的知识图谱分析
Research Hotspots and Prospects of Secondary School Geography Unit Teaching—A Knowledge Map Analysis Based on CiteSpace

基于CiteSpace软件对中国知网数据库进行文献检索，采用知识图谱可视化分析方法，探索近20多年来中学地理单元教学的研究动态。研究结果表明：中学地理单元教学目前处于快速发展阶段，但仍有不足，集中体现在：核心作者群体之间学术联系薄弱，合作研究较少；高发文机构多为高等院校，学术研究团体较为分散，尚未形成高凝聚力的研究团体；研究热点主题明确，但集中在教学设计理论研究，缺乏单元教学的实证研究。未来研究需加强研究者、研究机构间的合作；加强实证研究；拓展单元教学研究视野，促进研究科学化。
Based on the literature search of China Knowledge Network database by CiteSpace software, we used the visual analysis method of knowledge mapping to explore the research dynamics of secondary school geography unit teaching in the past 20 years. The research results show that the unit teaching of secondary school geography is in a rapid development stage, but there are still short-comings, mainly reflected in the weak academic ties between core author groups and less collaborative research; the high issuing institutions are mostly universities and colleges, and academic re-search groups are scattered and have not yet formed a high cohesive research group; the research hot topics are clear, but focus on theoretical research of instructional design and lack of empirical research on unit teaching. There is a lack of empirical research on unit teaching. Future research needs to strengthen the cooperation among researchers and research institutions, strengthen the empirical research, expand the research horizon of unit teaching and promote the centralization of research.
