“空间与图形”领域的学习是数学学习的重要组成部分,小学生由于思维发展水平的限制,在这个领域的学习中,解题的错误率相对较高,特别是第二学段的学生,因为第二学段涉及立体几何,学生的空间想象能力有限,将会给几何学习造成障碍,因此老师更应关注他们学习中出现的错题,以了解学生学习的困难,并展开针对性的教学。 The study of “Space and Graphics” is an important part of mathematics learning. Due to the limitation of the development level of thinking, pupils in this field have relatively higher error rate of solving problems, especially the students in the second semester Because the second semester involves three-dimensional geometry and students ’limited ability to space imagination will cause obstacles to the study of geometry, teachers should pay more attention to the mistakes they make during their studies so as to understand the difficulties of students’ learning and to carry out pertinent teaching.
