《数学课程标准(2011年版)》指出:“生成性资源是在教学过程中动态生成的,如师生交互及生生交流过程中产生的新情境、新问题、新思路、新方法、新结果等。合理地利用生成性资源有利于提高教学的有效性。”在小学数学课堂教学中,经常会遇到新的教学资源的生成,面对课堂教学中稍纵即逝的动态生成资源,教师要抓住契机,善于捕捉并有效利用,不断培
The Mathematical Curriculum Standard (2011 Edition) states: “Generative resources are dynamically generated in the teaching process, such as new situations, new problems, new ideas, new methods and new results arising from the interaction between students and students Etc. Reasonable use of generative resources is conducive to improving the effectiveness of teaching. ”In primary school mathematics classroom teaching, often encounter new generation of teaching resources, in the face of classroom teaching fleeting dynamic generation of resources, Teachers should seize the opportunity to be good at capturing and effectively using and cultivating
