Since the transformation of mathematics curriculum in secondary school,self-study,exploration- study and co-study have been emphasized in mathematics teaching.On the other hand,many teachers are per- plexed in the process of the transformation.Hence,the accurate understanding of acceptance-study is crucial for math teachers.Obviously,it is not enough to focus on the mathematic knowledge itself in the teaching process.As math teachers,they should pay more attention to the students' learning process,as well as their abilities of re- solving mathematical problems.Due to the rule of mathematics educational reform,adjusting and harmonizing the relationships of inheriting,developing and innovating should be taken into account.
