教学中,学生是学习的主体,教师应着眼于调动学生的学习积极性、主动性。教师应鼓励学生发现数学的规律和问题解决的途径,使他们经历知识的形成过程。但教材和练习中有很多难点内容,学生想用已有知识和经验自己解决是很困难的,这时候往往需要教师发挥主导作用。但这并不意味着教师“注入式、灌输式”地将知识教给学生,教师可以尝试将“难点”的教学内容分解成一系 Teaching, students are the main body of learning, teachers should focus on mobilizing students’ enthusiasm and initiative. Teachers should encourage students to discover the laws of mathematics and ways to solve problems so that they experience the formation of knowledge. However, there are many difficult content in teaching materials and exercises. It is very difficult for students to solve their own problems with existing knowledge and experience. Teachers often need to play a leading role at this time. However, this does not mean that teachers can “instill” knowledge into their students, and teachers can try to break down the “difficult” teaching contents into a series
