一个正确认识的获得,要经过由实践到认识、由认识到实践的多次反复。学生在课堂上获得的知识和掌握的方法,也要通过必要的练习,才能加深对知识和方法的理解。在小学数学教学中,练习质量的高低直接影响着教学效益,关系到学生数学素养的形成。因此教师在安排练习时不仅要考虑内容的设置,还应根据内容设计多样的形式,以激发学生练习的兴趣,深化对知识的理解,发散数学思维,提高练习的有效性。 The acquisition of a correct understanding goes through practice to understanding and from the realization of multiple repetitions of practice. Students acquire knowledge and methods in the classroom, but also through the necessary exercises, in order to deepen the understanding of knowledge and methods. In primary school mathematics teaching, the quality of practice directly affects the teaching effectiveness, which is related to the formation of students’ mathematical literacy. Therefore, teachers should not only consider the content setting when arranging exercises, but also design various forms according to the content to stimulate students’ interest in practice, deepen the understanding of knowledge, diverge mathematical thinking and improve the effectiveness of practice.
