“动态生成”是新课程改革的重要价值取向,而生成性资源又是实现这一取向的重要载体。动态生成性资源,是指在教学实施过程中,师生互动、生本互动、生生互动而引发的新问题、新方案、新观点和新思路等资源。面对动态生成资源,教师要智慧应对,敏锐取舍,机智地捕捉有价值的生成因子, “The dynamic generation” is an important value orientation of the new curriculum reform, and the generative resources are also important carriers for achieving this orientation. Dynamic generative resources refer to resources such as new problems, new programs, new ideas, and new ideas arising from interactions between teachers and students, interactions between students and students, and interactions between students and students. Faced with the dynamic generation of resources, teachers should respond intelligently, be selective, and intelligently capture valuable generative factors.
