为破解教师教育者缺乏中小学教学经验、师范生在真实情境中实践机会有限等问题，文章基于协同创新和深度学习理论，系统构建了智慧环境下的“U-S双师”课堂教学设计框架，提出网络直播、真情境教学和课例展示三种双师课堂实施路径以及表现性评价设计步骤，并将其用于实践，开展行动研究。文章认为，智慧环境下的“U-S双师”课堂具有师生协同的互惠性、教学过程的进阶性和学习环境的智能性，是高校教师教育者与中小学教师共同开发课程内容，通过线上线下联袂执教或线下共同教学等形式，为师范生提供多元参与体验和个性化指导机会，促进师范生知识迁移、问题解决和实践创新的一种课堂形态。实践表明，师范生肯定“U-S双师”课堂的教育价值，能够积极参与并顺利完成学习任务，获得较为扎实的数学教学知识，形成创新思维能力和自我发展能力，但是评课交流方面的高阶思维能力亟待加强。
【英文摘要】：
In order to solve the problems of teacher educators' lack of teaching experience in primary and secondary schools and normal students' limited practical opportunities in real situations, based on the theory of collaborative innovation and deep learning, this paper systematically constructs a framework for designing "U-S double-teacher" classroom in the intelligent environment. This paper puts forward three implementation paths of the double-teacher classroom, namely, webcasting, real situation teaching and lesson demonstration, and the steps of performance evaluation design, which are applied to practice to carry out action research. The paper believes that "U-S double-teacher" classroom under the intelligent environment has the reciprocity of teacher-student collaboration, the progressiveness of teaching process, and the intelligence of learning environment. It is a classroom form in which university teacher educators and primary and secondary school teachers jointly develop the curriculum content, provide normal students with multiple participation experiences and personalized instruction opportunities, and promote normal students' knowledge transfer, problem solving and practical innovation through online and offline co-teaching or offline co-teaching. Practice shows that normal students affirm the educational value of "U-S double-teacher" classroom, can actively participate in and successfully complete learning tasks, acquire solid mathematical pedagogical content knowledge, form innovative thinking ability and self-development competence, but their higher-order thinking ability in class evaluation and communication needs to be strengthened.
