数字教材在赋能教育教学变革的同时，也增加了教师角色扮演的复杂性和艰巨性：角色互动不当易导致角色模糊与角色焦虑，角色期待过高易导致角色超载与角色冲突，角色规范严苛易导致角色中断与角色失败。因此，教师个体如何完成角色转型是数字教材应用过程中亟须探究的命题。在数字教材应用过程中，教师面向学生发展的专业性角色将分为“聚合与统整”“分裂与细化”两个发展阶段。作为知识分子的公共性角色必须面向生活世界，做关切公共生活的现实人；敢于批判质疑，做担当公共责任的社会人；勇于传承创新，做弘扬公共文明的文化人。而生态重构的现实路径则由“内发”和“外铄”两条路径构成，教师自身要认识自己，成为自己，增强自己；外部要优化教材出版设计，质化教学评价模式，创建教师专业联盟，升级教师教育系统，以助力教师角色成长和角色更新。
【英文摘要】：
While digital teaching materials have enabled changes in education and teaching, they have also increased the complexity and difficulty of teachers' role-playing. Improper role interaction can easily lead to role ambiguity and role anxiety, high role expectations can easily lead to role overload and role conflict, and harsh role norms can easily lead to role interruption and role failure. Therefore, how to complete the role transformation of individual teachers is a urgent issue that needs to be explored in the application of digital teaching materials. In the application of digital teaching materials, the professional role of teachers for student development will be divided into two stages: "convergence and integration" and "fragmentation and refinement". Teachers, as the public role of an intellectual, must face the life world and become a real person concerned about public life. They dare to criticize and question, and become a social person who bears public responsibility. They must be brave to inherit and innovate, and become cultural people who carry forward public civilization. The realistic path of ecological reconstruction is composed of two paths of "internal development" and "external environment", in which teachers themselves must know themselves, become themselves, and strengthen themselves. Externally, it is necessary to optimize the design of textbook publication, improve the teaching evaluation model, establish teacher professional alliance, and upgrade teacher education system in order to help teachers grow and renew their roles.
