新课标指出:数学教学是数学活动的教学,是师生之间、学生之间交往互动与共同发展的过程。在课堂上应结合具体的教学内容采用“问题情境—建立模型—解释、应用与拓展”的模式进行教学。这种数学教学可以培养学生从问题情境中抽象出数学模型的能力,培养学生的数学思维,让学生可以利用数学知识解决生活中的问题。所以,我们在课堂上,要根据不同的教学内容和自己学生的不同特点,精心创设问题情境。这样可以发展学生的创新意识,
The new curriculum standard points out that the teaching of mathematics is the teaching of mathematics activities and the process of interaction, interaction and common development among teachers, students and students. In the classroom should be combined with the specific teaching content “problem situation - the establishment of model - interpretation, application and development ” model for teaching. This kind of math teaching can cultivate students ’abilities of abstracting mathematical models from problem situations, develop students’ mathematical thinking, and enable students to use mathematics knowledge to solve problems in life. Therefore, we in the classroom, according to different teaching content and their own different characteristics of students, carefully create the problem situation. This can develop students’ sense of innovation,
