数学来源于生活,服务于生活,生活是丰富多彩的,因此数学的学习是变化无穷的。人类从古至今积累了许多数学经验,摸索出许多数学真理、定理,也总结出许多数学公式,这些现成的经验,如果直接告诉学生,学生也能接受,但会使数学的学习枯燥乏味,也使学生对数学学习失去信心,只有学生经过探索发现后得出结论,才能对数学学习充满信心。教师应激起学生的兴趣,因此在数学课堂中培养学生探索发现的兴趣,进而形成一种自主学习的能力尤 Mathematics comes from life, serves life, life is rich and varied, so mathematics learning is endless. Humans have accumulated many mathematical experiences since ancient times, worked out many mathematical truths and theorems, and summed up many mathematical formulas. These off-the-shelf experiences can be accepted by students directly if they are told directly, but they will make the study of mathematics dull and tedious So that students lose confidence in the study of mathematics, only students through exploration and found that after conclusion, in order to have full confidence in math learning. Teachers should arouse the interest of students, so in the mathematics classroom students explore the discovery of interest, and thus form a kind of self-learning ability
