叶澜教授指出:“课堂应是向未知方向挺进的旅程,随时都有可能发现意外的通道和美丽的图景,而不是一切都必须遵循固定线路而没有激情的行程”。今天,在新课程标准指导下的小学数学课堂教学中必然会出现丰富的动态资源。它们只在瞬间产生,这就要求我们教师要做个有心人,及时捕捉这些教学信息,进行优化并有效地开发利用,提高数学课堂的实效性。
Professor Ye Lan pointed out: “Classroom should be an adventurous journey. You may find unexpected paths and beautiful pictures at any time, not everything that you have to follow a fixed route and no passion.” Today, there are bound to be abundant dynamic resources in the teaching of primary mathematics under the guidance of the new curriculum standards. They only happen in an instant, which requires us teachers to be considerate, timely capture of these teaching information, optimize and effectively develop and use, improve the effectiveness of mathematics classroom.
