《数学课程标准》指出:“学生的数学学习内容要有利于学生主动进行观察、实验、猜测、验证、推理与交流等数学活动”。建构主义理论认为:“数学学习并非是一个被动接受的过程,而是一个以已有知识经验为基础的主动建构的过程,也是一种再创造的过程。”因此,初中数学课堂教学应创设一种符合学生认知规律、轻松和谐的学习氛围,应当鼓励学生自主探究和合作交流,并不断地自我反思,最终灵活解决数学问题。
“Mathematics Curriculum Standards” pointed out: “The students’ mathematics learning content must be conducive to the students’ initiative to observe, experiment, guess, verify, reason and communicate and other mathematical activities.” The constructivist theory holds that: “Mathematical learning is not a passive process, but an active construction process based on existing knowledge and experience, and it is also a process of re-creation.” Therefore, mathematics teaching in junior middle schools should be Create a learning atmosphere that is consistent with the students’ cognitive laws and is easy and harmonious. Students should be encouraged to independently explore and cooperate and exchange, and they should constantly self-reflection and ultimately be able to solve mathematical problems flexibly.
