传统的数学习题单一呆板,严肃有余,缺乏童趣和人文性,让人一看就产生压抑感。有些机械、重复的练习不仅限制了学生的思维发展,还影响了学生的学习兴趣。在我们的课堂教学中也普遍存在着这样的现象:教师无视学生间的能力差异,用同样的要求让不同学生做同样的习题,致使成绩好的学生“吃不饱”而原地踏步,学习基础差的学生“吃不了”而苦恼厌学。这样必然会加重学生的心理负担,不利于学生的健康成长。 The traditional mathematical exercises a single dull, serious, lack of childlike and humanistic, people look at the resulting sense of oppression. Some mechanical and repetitive exercises not only limit the development of students ’thinking, but also affect students’ interest in learning. In our classroom teaching is also common in such a phenomenon: teachers ignore the differences in ability between students, with the same requirements for different students to do the same exercises, resulting in good students “enough to eat ” and the place to go , Students with poor basic learning “can not eat” and suffer annoyance. This will inevitably increase the psychological burden on students is not conducive to the healthy growth of students.
