作为思维形式的一种,求异思维中也孕育着创造思维的萌芽。我们在初中物理习题教学中应当注意和加强求异思维的训练,坚持以“教师为主导,学生为主体”的原则,紧密结合学生的年龄特点和知识实际,采取积极诱发的手段,真正达到使学生独立思考问题的目的。一、创设意境,激发情趣在学完密度知识以后,可设计下列这道题: 例1 有一根大约3米长,直径约0.1毫米的细金属丝,请你利用已学过的知识,设计出测出金属丝的密度的方案,仪器可任意选择。此例就属于求异思维意境的创设。题目一
As a form of thinking, divergent thinking also breeds the germ of creative thinking. We should pay attention to and strengthen the training of divergent thinking in the teaching of physics exercises in junior high schools. We must adhere to the principle of “teacher-led, student-centered,” and closely integrate the age characteristics of students and the actual knowledge, and adopt positively induced methods. To achieve the purpose of allowing students to think independently of issues. First, create mood, inspire interest After learning the density of knowledge, you can design the following questions: Example 1 There is a thin wire about 3 meters long, about 0.1 mm in diameter, please use the knowledge you have learned to design test The density of the metal wire can be selected arbitrarily. This case belongs to the creation of the different thinking mood. Topic 1
