函数概念的教学是一个重要课题。特别是初中阶段的函数概念的教学具有承上启下的作用,对它学习的好坏会直接影响到高中阶段函数概念的学习,乃至以后数学的学习。因此对函数概念教学的研究不仅是必要的而且应是深入的。一、加强函数概念的教学1.注意早期渗透。事实上,函数观念的培养在小学已经开始了。进入中学,随着代 The teaching of functional concepts is an important topic. In particular, the teaching of the concept of function at the junior high school level has a role to play, and it will directly affect the learning of the function concept of the high school stage, and even the future of mathematics learning. Therefore, the study of functional concept teaching is not only necessary but also in-depth. First, to strengthen the teaching of the concept of the function 1. Note the early infiltration. In fact, the cultivation of functional concepts has already begun in elementary schools. Entering middle school, with generations
