《数学课程标准》在“数学课程总体目标”中指出:“初步学会从数学的角度提出问题、理解问题,并能综合运用所学的知识和技能解决问题,发展应用意识。”同时指出:“知识与技能、数学思考、解决问题、情感与态度,这四个方面的目标是一个密切联系的有机整体,对人的发展具有十分重要的作用。要做到上述目标的有机结合,充分培养学生解决问题的能力,离不开培养学生的问题意识。”课堂是学生学习知识的园地,教师工作的根据地,而问题是数学课堂的心 “Mathematical Curriculum Standards” pointed out in “The Overall Objectives of Mathematics Curriculum”: “It is an initial learning to ask questions and understand problems from the perspective of mathematics, and can comprehensively apply the learned knowledge and skills to solve problems and develop application awareness.” “ At the same time, he pointed out: ”The goals of these four aspects of knowledge and skills, mathematical thinking, problem solving, emotion and attitude are all closely linked organic entities that play a very important role in human development. Combining and fully cultivating students’ abilities to solve problems can not be separated from cultivating students’ awareness of problems. “” Classroom is a base for students to learn knowledge and a base for teachers’ work.
