新课程改革着重提出,教学要发挥以学生为主体、以教师为主导的作用。在数学教学过程中应与学生积极互动,密切配合,共同发展。而教学过程中包含着多种互动因素,除师生互动外,生生互动也是非常重要的因素,是课堂中不可缺少的。因此,在教学过程中教师努力构建生生互动的平台,是决定着一堂数学课的气氛和成败的关键。 The new curriculum reform emphasizes that teaching should give play to the role of students as the main body and teachers as the leading role. In the process of mathematics teaching, students should actively interact, cooperate closely and develop together. The teaching process contains a variety of interactive factors, in addition to interaction between teachers and students, students interaction is also a very important factor in the classroom is indispensable. Therefore, in the process of teaching teachers to build a platform for life and play interaction, is to determine the atmosphere of a math class and the key to success.
