STEM导向的当代国际科学教育研究图景--基于NARST 2020年会的文本挖掘

STEM-based Research Prospect of Contemporary International Science Education:Text Mining Based on NARST 2020 Annual Meeting

科学教育是建设创新型国家以及呼应科教强国政策的根本,对于科技创新人才的培养至关重要。美国国家科学教学研究学会的年会代表了全球最高规格的科学教育研究盛典,基于NARST 2020年会报告题目和摘要,采用定性与定量相结合的文本分析法,依次进行了词频分析、主题建构和共现演化三个阶段的研究。研究发现:教师的教、学生的学、教师教育、课程评估、科学文化是本届科学教育年会五个研究领域,STEM是贯穿其中的核心议题。基于行为科学理论、活动理论和知识整合理论的管理学与教育学的跨学科研究框架和关键要素,可以把STEM研究划分为理论-实践、结构-功能,宏观-微观和心理-行动这八个维度构成的多元分析框架;无监督LDA主题模型的关系建模全面、清晰地确定了全球科学教育最新的六大研究主题的发展脉络与趋势;国际科学教育研究极为重视职前和职后教师教育,高质量的教师是科学教育改革的重要引擎和支撑,教师的教与学生的学是探究教学机制的关键。最后对西方思潮影响的中国科学教育改革提出了审思。

Science education is the fundamental foundation of building an innovative country and echoing the policy of strengthening the country through science and education. It is very important for the cultivation of innovative talents in science and technology. The annual meeting of the National Association for Research in Science Teaching represents the highest standard of science education research in the world. Based on the topics and abstracts of the report of NARST 2020 annual meeting as the research object,this paper adopts the method of qualitative and quantitative text analysis to conduct three research stages: word frequency analysis,theme construction and co-occurrence evolution. It is found that: teacher’s teaching,student’s learning,teacher’s education,curriculum evaluation and science culture are the five major research fields of this annual conference of science education,and STEM is the core topic running through them. Based on behavioral science theory,activity theory and knowledge integration theory,the interdisciplinary research framework and key elements of management and education can be divided into eight dimensions: theory-practice,structure-function,macro-micro and psychological-action;the relationship modeling of unsupervised LDA theme model comprehensively and clearly defines the development context and trend of the six research topics of the latest progress of global science education;international science education research attaches great importance to pre service and post service teacher education. High quality teachers are the important engine and support of science education reform.Teachers’ teaching and students’ learning are the key dimensions of exploring teaching mechanism. In the end,it puts forward some thoughts on the reform of science education in China influenced by western thoughts.
