一、问题提出的背景新课程改革的十年是我们不断探索的十年,也是我们数学教学不断进步的十年,随着新一轮课改的实施,我们能真正感觉到数学教学是在不断改革变化中逐渐成熟、逐渐完善、逐步提高的,在改革中认清形势,在改革中寻求方法,使我们的数学课堂真正成为学生成长的沃土、发展的阶梯、成才的摇篮,同时对教师的专业成长的发展也是不可多得的机遇。研究本课题也是对自己在课堂教学中的一些方法的总结、反思和提升,使我们的数学课堂能成为生动活泼的课堂、有效的课堂。 I. Background of the Problem The ten-year reform of the new curriculum was a decade that we continued to explore. It was also a decade of continuous progress in our mathematics teaching. With the implementation of a new round of curriculum reform, we can really feel that mathematics teaching is constantly Gradually mature, gradually perfected, and gradually improved during reforms and reforms, we must recognize the situation in the reforms, and seek ways in reforms so that our mathematics classrooms will truly become a fertile ground for student growth, a development ladder, and a cradle of talent. The growth of professional growth is also a rare opportunity. Researching this topic is also a summary, reflection, and promotion of some of the methods in class teaching. This makes our math class a lively classroom and effective classroom.
