作为数学教师进行备课的重要一环,数学作业同时也意味着课堂教学的继续和延伸。一个合理的数学作业设计对学生巩固数学概念,掌握运算方法,领会数学思维有着举足轻重的作用,其有效性也与数学教学的质量高低有直接关系。一、作业有效设计的内涵作业的有效性只是一个正在发展的概念,其主线是紧跟着教学有效性内涵的丰富而展开的,因课程改革、学生资质、教学要求等的变化而变化。普遍认为,新课程教学标准要求有效的作业设计应该是以尽可能少的精力、物力和实践投入,收获尽可能多的教学效果的实践活动。也就是说,“有效”包含效率,效益和效果这三个层面。
As an important part of mathematics teacher preparing class, math homework also means the continuation and extension of classroom teaching. A reasonable design of math homework for students to consolidate the concept of mathematics, mastery of computing methods, understand mathematical thinking plays a decisive role, its effectiveness is also directly related with the quality of math teaching. First, the effective design of homework The effectiveness of homework is just a developing concept, the main line is followed by the enrichment and expansion of the meaning of teaching effectiveness, due to changes in curriculum reform, student qualifications, teaching requirements and other changes. It is generally agreed that the new curriculum teaching standard requires that effective job design should be a practical activity that rewards as much teaching as possible with as little energy, material resources and practice as possible. In other words, “valid ” contains three levels of efficiency, effectiveness and effectiveness.
