小学数学的教育是属于基础阶段的教育,小学数学知识的应用也跟其他学科有些联系,小学数学的学习成果会或多或少地影响其他学科的学习。随着新课程改革的速度加快,教师要想办法改进自己的教学方法,提高小学数学课堂的趣味性。教师要让学生主动地进行课堂学习,调动学生的学习积极性,真正让学生成为学习的主体,这才符合素质教育教学理念。反例教学改变了传统教学中教师主动教授、学生被动学习的固定模式。教师通过反例与原例的对比来提高数学 Elementary mathematics education belongs to the basic stage of education. The application of elementary mathematics knowledge is also linked with other disciplines. The results of primary mathematics learning will more or less affect the learning of other subjects. As the speed of new curriculum reform accelerates, teachers should find ways to improve their teaching methods and improve the interest of primary mathematics classrooms. Teachers should let students take the initiative to carry out classroom learning, mobilize the enthusiasm of students to learn, and really let students become the main body of learning, which is consistent with the concept of quality education and teaching. Counterexample teaching has changed the traditional teaching teachers active professors, students passive learning fixed pattern. The teacher improves mathematics by comparing the counter example with the original case
