　　Classroom observation is defined as a process by which the observer sits in a classroom ， records the teacher’s teaching practices and student actions， and then meets with the teacher to discuss the observations （ Daniel Weisberg， Susan Sexton，， Jennifer Mulhern， and David Keeling，2009）.Generally speaking ，classroom observation is conducted through three stages： pre-observation meeting， observation， and post-observation. The purpose of pre-observation meeting is to share information that facilitates both the teacher and the observer to prepare for the observation. The observation stage is about data-collection ，which include the teacher’s and students’ doing and saying， and the interaction of them. The post-observation is a descriptive stage where the observer describes the lesson from different perspectives and the teacher is also asked to reflect on his/her teaching.
