在小学数学教学中,解决实际问题是重点,也是难点所在。怎样提高学生解决实际问题的能力呢?笔者认为,在数学课堂上,练习是提高学生解决实际问题能力的主阵地,而从以下三个层次精心设计变式练习能起到很好的效果。一、突出基础,精心设计对比练习提高解决问题的能力,关键是夯实基础,正确分析问题的数量关系,学习过程中的对比练习可以帮助学生准确抓住问题的本质。
In elementary mathematics teaching, solving the practical problems is the key point as well as the difficulty. How to improve the ability of students to solve practical problems? The author believes that in mathematics classroom, practice is to improve students ability to solve practical problems of the main battlefield, and from the following three levels meticulous design variant exercises can play a very good effect. First, highlight the foundation, well-designed contrast Practice to improve the ability to solve problems, the key is to lay a solid foundation to correctly analyze the relationship between the number of questions, the learning process can help students accurately grasp the essence of the problem.
