With the gradual development of new media and new technologies, the Internet has changed the traditional teaching. Participating in the process of COP project, the author takes the open class of the whole district as an example to show the three phases of the data-based focused classroom observation technology: “Recycling Waste - Solving ” more than a few " Traditional classroom observation stage, focused classroom observation stage and active practice internalization stage. And show the reflection of teaching effectiveness and reflection, teachers how to have a deep dialogue with students, teachers how to guide students in exploring and thinking, teachers how to inspire students to more effectively experience the process from figurative to abstract, in-depth understanding of the focus of the classroom The nature of mathematical problems.
