中学数学教学是在一定经验基础上的教学。学生在接受新知识之前,头脑中对于该知识领域中的客观事物已经形成了常识、信念以及日常生活经验和在直觉知识上建立的概念、规律、思想方法、逻辑素质等,它是以强烈的情感色彩构造出来的图式,并用这种图式对输入的刺激进行处理和鉴别。象这种在知觉过程中对知觉对象的某种图式不加分析地扩展到其它方面并阻碍了新知识学习的心理现象称之为负图式效应。
Middle school mathematics teaching is based on certain experience. Before students accept new knowledge, they have formed common concepts, laws, methods of thinking, logical qualities, etc. that are common knowledge, beliefs, and everyday life experiences and intuition knowledge in the mind. A schema constructed from emotional colors and uses this schema to process and identify input stimuli. For example, this kind of psychological phenomenon that extends to other aspects of the perceptual object in the perceptual process without analysis and hinders the learning of new knowledge is called the negative schema effect.
