一直以来,初中化学对于实验和概念的教学都比较注重,强调通过各种科学有效的方法,综合地促进学生水平及能力的提升。初中化学,对于学生而言,是一门全新的课程。这门学科的内容是陌生的,因而存在许多全新的概念,必须经过一个有效的认识过程,才能正确认识这些新内容。为了帮助学生科学简单地掌握这些内容,许多教师选择引入了图示理论,通过图片在人脑海中迅速产生的反响和记忆,将各种化学概念直接地展示给学生,进而有效地培育学生
Junior high school chemistry has always been more emphasis on the teaching of experiments and concepts, and emphasizes the promotion of students’ ability and level of students through a variety of scientific and effective methods. Junior high school chemistry, for students, is a new course. The content of this discipline is unfamiliar, so there are many new concepts, must be an effective understanding of the process in order to correctly understand these new content. In order to help students to master these contents in a scientific and simple way, many teachers have chosen to introduce the pictorial theory to present various chemical concepts directly to students through the rapid reaction and memory of the pictures in their minds so as to effectively cultivate students
