? The students watched the video of onion mathematics last night. The teacher previews the test and studies with questions. At the same time, these issues are also the focus of this section. The teacher chooses students to show according to the difficulty of the question. If there are any deficiencies or disputes, please add them. When in doubt, the teacher asks questions to make students think and see the essence of the problem. Teachers don't have to waste too much time explaining simple problems, leaving more time to solve the two-star and three-star problems in basic training.
? Through group discussion and communication, students have gained many methods and ideas, and can better find problems. Class time is mainly used to solve students' problems and extend the depth of the problems.
? Flipping the classroom is to put the process of knowledge transfer outside the classroom, watch videos, put the process of knowledge internalization in the classroom, and communicate with students face to face. Its basic operation flow is: first, learn independently, let students learn with the questions in the study plan, then test the learning effect and adjust the teaching strategies, including summing up the promotion, answering questions, organizing discussions and guiding the promotion. "Flip the classroom" refers to turning the teaching structure of "teachers have classes in the classroom during the day and students go home to do their homework at night" and constructing the teaching structure of "students complete the internalization process of knowledge absorption and mastery in the classroom during the day and go home to learn new knowledge at night", thus forming a new classroom teaching structure that allows students to complete the internalization process of knowledge absorption and mastery in the classroom and complete knowledge learning outside the classroom. This solves the problem that students will hear wrong after class.
? The use of technology, mobile phone whiteboard synchronization, students' homework synchronous display, and the internet joining the classroom have brought a brand-new era to education. To quote Teacher Liu Xinyan, "I am moving towards classroom reform".
