《数学课程标准》明确要求:面对实际问题时,学生能主动尝试着从数学的角度运用所学知识和方法寻求解决问题的策略。而要培养学生解决实际问题的能力,教师在应用题教学中就必须创设各种情境,注重数学知识的来龙去脉,尽可能地应用心理学的原理指导应用题教学,把应用题由浅入深,由易到难的过程呈现给学生,并进行多种形式的训练,让学生掌握应用题的结构和解答应用题的思路,来提高学生的解题能力,使学生在解题时能化繁为简,化难为易。 The standard of mathematics curriculum clearly stipulates that in the face of practical problems, students can take the initiative to try to find a solution to the problem from the perspective of mathematics using the learned knowledge and methods. To cultivate students’ abilities to solve practical problems, teachers must create a variety of contexts in the teaching of applied problems, pay attention to the ins and outs of maths knowledge, use the principles of psychology as much as possible to guide the teaching of application problems, Easy to difficult process presented to the students and conduct various forms of training so that students master the structure of the application questions and answer the idea of ​​application questions to improve the ability of students to solve problems so that students can simplify the problem solving , The difficulty is easy.
