新课程改革以来,小学数学教材中新增了“解决问题的策略”相关内容,其目的是要将学生的解题能力进行专项的训练。这对提高学生的思维水平,实现学生数学学习的序列化和专题化是极为有效的。但是,教学中我们也发现,如果过度分散地教学这部分内容,人为地将解决问题的综合化策略进行分割式的研究,不符合解决实际问题的需要,阻碍学生综合能力的发展与提升。我在教学中,常常借助于一些有价值的题组练习,着力培 Since the reform of the new curriculum, primary school mathematics textbooks have been newly added with the content of “problem solving strategies”, and its purpose is to carry out special training for students’ problem solving skills. This is to improve the level of students’ thinking, to achieve the serialization and specialization of student math learning is extremely effective. However, we also found in teaching that if we over-disperse this part of teaching, we should artificially divide the comprehensive strategy to solve the problem without meeting the need of solving practical problems and hindering the development and improvement of students’ comprehensive ability. I am teaching, often with the help of some valuable group exercises, focus on training
