《数学课堂标准》指出:“数学教学要密切联系学生的生活实际,从学生的生活经验和已有的知识出发,创设各种情境,为学生提供从事数学活动的机会,激发学生对数学的兴趣,以及学好数学的愿望.”所以创设有效的数学情境,有利于提高课堂效率,激发学生学习热情和兴趣,有利于学生掌握数学知识和技能.教学活动中,要创设良好的问题情境,可以从以下几个方面考虑:
Mathematical Classroom Standards states: “Mathematics teaching should be closely linked with the students’ actual life. Based on the students’ life experiences and existing knowledge, various situations should be set up to provide students with the opportunity to engage in mathematical activities and stimulate students’ Interest and the desire to learn mathematics. ”Therefore, to create an effective mathematical situation is conducive to improving classroom efficiency and stimulating students’ enthusiasm and interest in learning, so as to help students master mathematical knowledge and skills. In teaching activities, it is necessary to create a sound problem situation, Can be considered from the following aspects:
