教师在教学研究的过程中,必须注意学生的一个重要的心理因素——“感情”。“感情和认识过程不同,认识过程是人对客观事物本身的反映,而感情则是对事物的一种好恶的倾向,……是人对客观事物的一种态度”。在教学过程中,应利用必要的“刺激”,使学生在大脑皮层的有关区域内产生优势兴奋中心,引发他们的积极情意。因为每当人的周围出现新异的刺激时人就会将自己的感受器朝向新异刺激,以便更好地感知这一刺激,初步判明它“是什么”,甚至探究它“为什么”。这就是人们通常所说的“唤起求知欲”。下面就初中物理新课引入中的“刺激”谈一些不成熟的看法。一趣:“兴”从“趣”中来,要使学生 In the process of teaching and research, teachers must pay attention to an important psychological factor of students: “emotions.” “The process of feelings and understanding is different. The process of cognition is the reflection of people on the objective things themselves, and the feelings are a kind of likes and dislikes towards things.... It is an attitude of people to objective things.” In the teaching process, the necessary “stimulus” should be used to enable students to create centers of excellence and excitement in the relevant areas of the cerebral cortex, triggering their positive affection. Because each time people around the emergence of new and different stimuli, people will be their own sensor towards the new stimulus, in order to better perceive this stimulus, initially determine it “what”, and even explore it “why.” This is what people commonly call “the arousal of curiosity.” In the following, I will talk about some immaturity about the “stimulus” introduced in the new physics class for junior middle school. A Fun: “Hing” comes from “Interesting” to make students
