在学习教育专家吴正宪老师的教育思想时看到这样一句话:“在学生学习过程中,没有什么比激发学生兴趣、保护学生好奇心更重要。”数学学习过程就是学生建构数学知识的过程,那么巧设认知冲突就是激发学生好奇心的一个重要手段,这样就能突出“四基”与“四能”。近日,有幸听到了三年级下册数学《众数》一课,徐老师 In the education of education expert Wu Zhengxian teacher’s education thought to see such a sentence: “In the student learning process, there is nothing more than to stimulate student interest, curiosity to protect students is more important. ” Mathematics learning process is the process of students to build mathematical knowledge , Then clever cognitive conflict is to stimulate curiosity of students is an important means, so that we can highlight “four bases ” and “four can ”. Recently, fortunate enough to hear the third grade mathematics “mode” a class, Xu teacher
