创设问题情境是指根据教学内容,结合学生的认知发展水平和已有的知识经验,将学习内容设计成若干与学生生活接近、具有一定的趣味性和挑战性的问题。问题意识可以激发学生勇于探索、创造和追求真理的科学精神,还可以加深学生对数学价值的认识。一、创设问题情境,激发学生的学习兴趣在讲“平移和旋转”一节课时,由于旋转是新教材所独有的内容,它符合学生的认知规律,从生活中找到数学,使学生不在感到
The creation of a problem situation means that based on the teaching content, combined with the level of cognitive development of students and the existing knowledge and experience, the learning content is designed into a number of issues that are close to the students’ lives and have some interestingness and challenges. Problem awareness can stimulate students to dare to explore, create and pursue the spirit of science, but also deepen students’ understanding of mathematical value. First, to create a problem situation to stimulate students’ interest in learning In the “shift and rotate ” a class, because the rotation is unique to the new textbooks, it is consistent with the cognitive rules of students, to find mathematics from the life, so that Students do not feel it
