小学数学教学中创设良好的情境,有助于学生实现原有认知结构对新知的同化和顺应,使原有认知结构得到补充和完善,激发起学生主动地将新旧知识发生相互联系,相互比较,主动找到适应新的问题情境下解决问题的新方法和途径,并有效地学习新知。因此,在数学教学中,让学生在情境中愤悱,在情境中历练,在情境中发展,培养学生实践能力。 Primary school mathematics teaching to create a good situation, help students to achieve the original cognitive structure of the assimilation and adaptation of new knowledge, so that the original cognitive structure has been added and improved, inspired students to take the initiative to new and old knowledge interrelated, mutual Compare and take the initiative to find new ways and means to solve problems in the new situation and learn new knowledge effectively. Therefore, in mathematics teaching, students should be resentful in the situation, experienced in the situation and developed in the situation to cultivate students’ practical abilities.
