The development of the subject and the mature of teaching should be based on the deeper research on the classroom teaching. The article attended and photographed a young expert teachers´ classroom teaching of informational technology subject for over one month, then analyzed six classes with NVIVO. The result shows that this teacher is good at guiding students to observe, think then answering, leaving enough time for them to thinking and practicing, helping special students, etc. However there is still some weakness such as too much time on simulating tasks or repeating tasks than innovating and complex tasks.
