T-M-S互动模式强调只有教师(T)—学生(S)—材料(M)三极形成良好的互动时,教学效果才能到达最佳值。而在语文课堂教学实践中,板书领域往往由教师独自操作,不对学生开放,从板书的设计到板书的完成,学生始终被排除在外,难以参与,根本不能形成互动局面。圆形板书以其独特的留白艺术,为学生留下了足够的发挥空间,使学生有了参与板书的机会。可以说,圆形板书在T-M-S互动模式中的应用,正是打破教师在板书领域的话语霸权的一种有效方式。 The T-M-S interactive mode emphasizes that teaching effects reach the optimum only when there is good interaction between the teacher (T) - student (S) - material (M) triad. In the practice of Chinese classroom teaching, the field of the blackboard is often operated by the teachers alone and not open to the students. From the design of the blackboard to the completion of the blackboard, the students are always excluded from participation and can not form an interactive situation at all. The unique shape of the circular blackboard book leaves plenty of space for students to take part in the writing process. It can be said that the application of circular plate in the T-M-S interactive mode is an effective way to break the discourse hegemony of teachers in the field of blackboard.
