数学学习的本质是学生获取数学知识,形成数学技能和能力的一种思维过程。怎样才能让抽象的数学知识易于学生理解、学习呢?这就得靠课堂教学的组织者-教师,要把抽象的数学知识形象化。学生再用形象的思维,结合自己生活中的经验,展开他们想象的翅膀,探究解决数学问题,获得相应的数学技能。课堂上教师同样 The essence of mathematical learning is a thinking process in which students acquire mathematical knowledge and form mathematical skills and abilities. How to make abstract mathematical knowledge easy for students to understand and learn? This depends on the classroom teaching organizers - teachers, abstract mathematical knowledge should be visualized. Students then use the image of thinking, combined with their own experience in life, expand their imaginary wings, to explore and solve mathematical problems, access to appropriate mathematical skills.
