【缘由】随着新课程的逐步推进,人们在理念上已达成“以人为本”的共识,注重学生自主参与学习,但在具体教学实践中,往往只停留在表面上的热热闹闹,学生真正参与探索、构建、讨论与交流的成效却很低。因此,我们进行了“如何设计有效的课堂教学”的实践研究,遵循“设计——实践——反思——再设计——再实践——再反思”的研究之路,在“实验课”的基础上,修订教案,再作第二次实践,分别在同年级的两个班进行教学,带来的结果是“柳暗花明又一村”的欣喜和快感。现将教学过程描述如下。 [Reasons] With the gradual advancement of the new curriculum, people have reached a consensus of “people-oriented” in philosophy and focus on students’ independent participation in learning. However, in specific teaching practice, they usually only stay superficially on the surface and students really participate The effectiveness of exploration, construction, discussion and exchange is low. Therefore, we conducted a practical research on “how to design effective classroom teaching”, followed the research path of “Design - Practice - Reflection - Redesign - Practice - Rethinking” Based on the revised teaching plan, and then for the second practice, respectively, in the same grade two classes for teaching, the result is the “brilliant” another joy and pleasure. Now the teaching process is described below.
