教育家布鲁姆·乔伊斯说:“教会学生思考,我们就给了他们自己教育自己的能力.”衡量课堂教学效果的一个重要标志就是学生思维能力在多大程度上得到挖掘和培养.本文以立几中一个命题的教学过程为例,谈谈如何优化例题教学结构及培养学生的思维能力. Educator Broy Joyce said: “To teach students to think, we give them the ability to educate ourselves.” An important indicator of the effectiveness of classroom teaching is how much the students’ thinking ability is excavated and nurtured. Take the teaching process of a proposition as an example, talk about how to optimize the teaching structure of the example and train students’ thinking ability.
