在小学数学教学中,根据教学的需要,教师常常创设一种教学情境,引导学生进行数学知识学习。数学教学情境的创造,可以有效激发学生的学习兴趣,正确引导学生的思维,进而让学生在愿学、乐学的范围中学习,提高数学教学质量。但是,有的教师所创设的教学情境,表面上看起来热热闹闹,学生们似乎是积极地、主动地参与了教学活动,实际上学生却没有有效参与学习,所谓的创设情境只 In primary school mathematics teaching, according to the needs of teaching, teachers often create a teaching situation to guide students to learn mathematics. The creation of mathematical teaching situations can effectively stimulate students ’interest in learning and guide students’ thinking correctly, so as to enable students to learn in the range of learning and learning and improve the quality of mathematics teaching. However, the teaching situations created by some teachers may seem bluster on the surface. Students seem to be actively and actively participating in teaching activities. In fact, students are not effectively involved in learning. The so-called situation-setting
