初中数学PCDC问题中心双循环教学模式,使学生在解决任务问题时,在活动任务中不断反思抽象,提升自己的概念层次。通过深入反思,在脑中将行动内化为过程,解题运作,再由进阶反思抽象,促成其概念的提升。以“问题”贯穿于教学全过程是教学模式的创新特色,学生通过探究解决问题,师生共同归纳总结。真正培养学生的创新精神和创造能力。 Junior high school mathematics PCDC problem center double cycle teaching mode, so that students in the task of solving the problem, in the activities of the mission continue to reflect on the abstract, enhance their conceptual level. Through in-depth reflection, the internalization of action in the brain as a process, problem-solving operation, and then by the advanced reflective abstract, to promote its concept upgrade. To “problem ” runs through the whole process of teaching is the innovative features of the teaching mode, students solve problems through exploration, teachers and students together concluded.
