化学变化是微观领域里的变化,物质的组成、结构及变化的实质通常都无法直接感知,中学化学教学中,怎样通过直观教学促进学生思维的发展,帮助他们理解和掌握知识的规律是一个很重要的问题,本文拟就这一问题谈谈自己的肤浅认识。 一、直观教学的心理依据 学生对知识的掌握首先要经过对教材内容的感知才能上升到理解。直观教学就是利用学生的多种感官(视觉、听觉;触觉、味觉等)和已有经验,通过各种形式的感知(感觉、知觉、表象等),使学生获得丰富的感性知识,为学生抽象思维打下基础,所以采用直观手段必须从提高感知效果出发。而人的大脑对外界事物的感知效果与被感知的对象有密切关系,通常,被感知 Chemical change is a change in the micro field. The composition, structure, and nature of changes often cannot be directly perceived. In chemistry teaching in middle schools, how to promote the development of student thinking through intuitive teaching and help them understand and master the laws of knowledge is a very The important issue is that this article intends to discuss its own superficial understanding of this issue. First, the psychological basis of intuitive teaching Students master the knowledge first of all through the perception of the content of the textbook to rise to understanding. Intuitive teaching is the use of a variety of sensory (visual, auditory, tactile, taste, etc.) and existing experience of students, through various forms of perception (feelings, perceptions, appearances, etc.) to enable students to obtain a wealth of emotional knowledge, for students to abstract Thinking lays the foundation, so the use of intuitive means must start from improving perception. The perception effect of the human brain on the outside world is closely related to the perceived object. Usually, it is perceived.
