面对新时代教师队伍建设的要求，教研有必要向个性化、精准化转型。依托各种智能技术对教师画像，成了破解精准教研难题的创新途径。然而，目前精准教研视域下的教师画像研究，在国内尚属空白。文章从教研数据采集、分类及其有效关联等角度阐释了数据驱动的教师画像的实施可行性；同时，剖析了教师画像的实现流程，包括教研数据预处理、教师画像模型建构、教师个体标签体系建立和教师画像质量评估四大环节，从而提供了清晰的框架指引。文章最后提出教师画像的四大应用场景，涵盖教师、决策者、教研服务提供方和学生等利益者视角。该研究从精准教研视域下教师画像的实现必要性、实施可行性、实现方法和应用场景作了系统论述，旨在为相关研究提供参考。
【英文摘要】：
Because of the demands for the construction of teaching staff in the new era, teaching and research need to be personalized and precise. Portraying teachers with various intelligent technologies is becoming an innovative way to solve the problem of precise teaching and research. However, at present, the study on the teachers' portraits from the perspective of precise teaching and research is still a blank in China. This paper illustrates the feasibility of data-driven teachers' portraits in the view of data collection, classification and effective correlation about teaching and research. Meanwhile, this paper analyzes the implementation process of teachers' portraits, including the data preprocessing, the modeling of teachers' portraits, the establishment of teachers' individual label system, and the quality evaluation of teachers' portraits, which provides a clear framework. Finally, this paper proposes four application scenarios for portraits of teachers, covering the perspectives of teachers, decision makers, service providers of teaching and research and students. This study makes a systematic discussion on the necessity, feasibility, methods and application scenarios of teachers' portraits form the perspective of precise teaching and research, aiming to provide reference for the related research.
