一、创设教学情境的原则1.注意情境的真实性.教学情境具有认知性、情感性和实践性.其真实性才是认知性、情感性和实践性的保证.数学是所有学科中抽象程度相对较高的一门学科,中小学生的心理发展特点决定了其数学学习在很长的一个时段需要相对具体形象的材料来支撑,因此在结合相应课题设计情境时,应避免那些脱离现实的、人为编制的情境.2.注意情境的全程性.教学情境的创设,不是传统意义上的引入新课.情境不仅在讲新课前发生
First, the principle of creating teaching situations 1. Pay attention to the authenticity of the situation. The teaching situation is cognitive, affective, and practical. Its authenticity is the guarantee of cognition, affection, and practicality. Mathematics is the subject of all disciplines. In a discipline with a relatively high degree of abstraction, the psychological development characteristics of primary and secondary school students determine that mathematics learning needs to be supported by relatively specific image materials for a long period of time. Therefore, in the context of designing the corresponding topic, those who are disengaged from reality should be avoided. The situation of artificial preparation. 2. Pay attention to the whole course of the situation. The creation of teaching situations is not the introduction of new lessons in the traditional sense. The situation not only occurs before the new class is taught.
