新课程改革以来,一直呼唤民主、探究、合作的学习方式。由此,探究之风在数学课堂教学中一度盛行,但很多的探究方式并非都是在适切的状态下进行的,从而失去了探究的真正价值。在真实情境下唤醒学生内在的学习需求,在切实素材中解决学生真正的学习难点,在智慧争辩时搭建学生思维的学习桥梁,从而使数学探究起到实效。 Since the reform of the new curriculum, we have been calling for a democratic, inquiry-based and cooperative learning approach. As a result, the style of inquiry prevailed in mathematics classroom teaching, but many of the ways of inquiry were not carried out under appropriate conditions, thus losing the true value of inquiry. Arouse students ’inherent learning needs in real situations, solve the real learning difficulties of students in practical materials, and build a learning bridge for students’ thinking during their wisdom argumentation so as to make mathematical inquiry play a real role.
