初中数学课堂教学中,选择恰当的数学素材,创设一个适合学生学习和发展需要的情境,是非常必要的。创设情境利于激发学生们的学习兴趣、还能够激活他们的思维,有效情境的创设还有利于展现知识的发生过程,“掐头去尾烧中断”的教学也正在逐渐的减少,因此,创设数学情境教学也越来越受到数学教师们的重视。 In middle school mathematics classroom teaching, it is very necessary to select appropriate mathematical material and create a suitable situation for students’ learning and development needs. Creating a situation conducive to stimulate students’ interest in learning, but also to activate their thinking, the creation of effective context is also conducive to show the occurrence of knowledge process, “” to the end of the tail burning interrupt "teaching is also gradually reduced, therefore, The establishment of mathematical situation teaching is also increasingly valued by math teachers.
