课堂情景是要为教学服务的,它所发挥的作用就是从情境、生活、学生感观的获得过渡到数学含义的提炼、数学方法的理解,飞跃到一种理性的概括和思考应用。课堂教学情景不只存在于课堂教学开始,而是充满课堂教学的整个过程,只要有学习活动的进行,就有相应的学习情景。所以,良好的教学情景能充分调动学生学习的主动性和积极性,启发学生思维、开发学生智力,是提高数学学科教学实效的重要途径。以下是探索课堂情景的一些方法:
Classroom situation is to serve for teaching, and its role is to leap from a situation, life, student perception of the transition to the mathematical meaning of the extraction, understanding of mathematical methods, leapfrog to a rational summary and thinking applications. The classroom teaching situation not only exists in the beginning of classroom teaching but in the whole process of classroom teaching. As long as there are learning activities, there are corresponding learning scenarios. Therefore, a good teaching situation can fully mobilize the initiative and enthusiasm of students, inspire their thinking and develop students’ intelligence, which is an important way to improve the teaching effectiveness of mathematics. Here are some ways to explore a classroom scenario:
