在高三一轮复习的一节试卷评讲课中,笔者借助于一道例题展开教学,依据“问题引领,自主建构”教学模式,使得课堂的建构变得自然.数学教育家张乃达老师说过:“数学问题是推动数学思维的动力.”深刻分析学生的解题过程,从过程中发现问题,以这些问题为切入口去引领课堂,激发学生探究数学,体验数学,建构数学的热情,从而提升课堂的思维能力.在这样的课堂中学生才不会被动接受老师的方法,也不会仅仅止步于修正自己
In a senior high school exam review papers section of the lecture, the author with the help of a case study, according to “lead the question, self-construction” teaching mode, making the classroom construction become natural .Mathematics educator Zhang Nida teacher said : “Mathematical problems are the driving force for promoting mathematical thinking.” "Profound analysis of students’ problem-solving process, discovering problems from the process, taking these problems as an entry point to lead the classroom, inspire students to explore math, experience mathematics, build math enthusiasm , So as to enhance the ability of thinking in class.In this class, students will not passively accept the teacher’s method, nor will they just stop at correcting themselves
