中小学教师TPACK转化为数字素养的作用机制研究:一个链式中介模型

Research on the Mechanism of Transforming TPACK into Digital Literacy for Primary and Secondary School Teachers:A Chain Mediation Model

中小学教师数字素养是推动基础教育数字化转型的关键软实力,是构建高质量教育体系的重要支撑,提升中小学教师数字素养迫在眉睫。本研究从具身认识论视角出发,采用问卷调查法并基于多元回归分析与结构方程模型,深入探究中小学教师TPACK、技术接受度、技术应用行为转化为数字素养的作用机制。研究发现,中小学教师数字素养整体水平有待加强,城乡教师间存在显著差异;教师TPACK是中小学教师数字素养形成的关键要素;技术接受度、技术应用行为在中小学教师TPACK转化为数字素养过程中分别发挥中介与链式中介作用。基于上述研究结果,建议从以下方面提升中小学教师数字素养:完善教师知识结构,由TPACK转向AI-TPACK学习;以极简思维甄选符合学科需求的教学工具,提升教师技术接受度;研制“整校推进”的教师数字技术应用能力提升模式,基于循证理念发展教师合理的技术应用行为。

The digital literacy of primary and secondary school teachers is a key soft power in promoting the digital transformation of basic education,and an important support for building a high-quality education system.It is urgent to improve the digital literacy of prima-ry and secondary school teachers.From the perspective of embodied epistemology,this study adopts the questionnaire survey method,based on muliple regression analysis and structural equation model,and deeply explores the mechanisms by which primary and secondary school teachers'TPACK,technology acceptance,and technology application behavior transform into digital literacy.The results show that the over-all level of digital literacy of primary and secondary school teachers needs to be strengthened,and there are significant differences between urban and rural teachers;Teachers'TPACK is the key factor for the formation of digital literacy of primary and secondary school teachers.Technology acceptance and technology application behavior play mediating and chain mediating roles respectively in the process of transfor-ming TPACK into digital literacy for primary and secondary school teachers.Based on the above research results,it is proposed to promote digital literacy of primary and secondary school teachers.Improving the knowledge structure of teachers and shift from TPACK to AI-TPACK learning;Using minimalist thinking to select teaching tools that meet the needs of the subject and enhance teachers'technical ac-ceptance;Developing the"school wide promotion"model for improving teachers'digital technology application capabilities,and develop reasonable technology application behaviors based on evidence-based concepts.
