一、问题情境的创设原则1、设置的情境问题要有明确的目的性教师要根据教学任务、教学内容、教学目标适时地创设问题情境,使学生有的放矢,明确要学什么,为什么要学。激发学生的学习兴趣,使其自觉地、主动地探索问题,获取新知。2、设置的情境问题要有鲜明的针对性问题情境的设置应有一定的针对性,即针对学生认知上的缺口和疑处。教师在创设问题情境时,一定要紧扣课题,不要故弄玄虚,离题太远,要能揭示数学概念或规律,要直接有利于当堂所研究课题的解决,要有利于激发学生思维的积极性,体现出问题情
First, the creation of the principle of the problem principle 1, set the situation to have a clear purpose of the problem Teachers should be based on teaching tasks, teaching content, teaching objectives and timely creation of problem situations, so that students targeted, clear what to learn, why should learn. Stimulate students interest in learning, so that they consciously and proactively explore the problem, access to new knowledge. 2, Set the situation to have a clear problem-oriented problem settings should have a certain context, that is, for the students cognitive gaps and suspicions. When teachers create problem situations, they must be closely linked to the subject. They should not make mistakes and depart too far. To reveal the concept or law of mathematics, it is directly conducive to the solution to the problems studied in the classroom. It is helpful to arouse the enthusiasm of students in thinking and embody Problem
