练习是课堂教学中一个重要的环节,是巩固新知、形成技能、发展思维的重要手段。当前课堂中有这样一种错误倾向:重例题开发,轻习题设计;重结果的正误,轻过程的展开;忽视练习的价值,不注重开发和生成习题功能。在新课程理念下,该如何追寻有价值有效度的习题设计呢?结合自己多年的教学实践,我觉得可以尝试融合资源,把握优化的尺度;改变方式,体验生成的温度;挖掘素材,促进感悟的深度;拓展内容,丰富知识的厚度。这样,习题设计就能在多元的价值追寻中绽放精彩! Exercises are an important part of classroom teaching and an important means to consolidate new knowledge, form skills and develop thinking. In the current classroom, there is such a tendency of error: the development of severe cases and the design of light exercises; the development of positive and false results and light processes; the neglect of the value of exercises and the neglect of developing and generating exercises. Under the concept of new curriculum, how to pursue valuable and effective exercises design? With my years of teaching practice, I think you can try to integrate resources, grasp the scale of optimization; change the way to experience the temperature generated; to tap the material to promote awareness Depth; to expand content, enrich the thickness of knowledge. In this way, the exercise design will be able to bloom in the pursuit of diversity of exciting!
