Adhere to lifelong learning and strive to broaden your knowledge. Although the backbone teachers have been teaching for more than ten years, they are relatively weak, and the design and treatment of teaching links are often decided by intuition or experience, lacking rational and meticulous thinking. However, under the new situation of new curriculum reform, teachers must constantly broaden their knowledge, strengthen their study and improve themselves. In this sense, one of the keys for backbone teachers to break through the plateau period is to strengthen the systematic study of educational theory and guide practice with systematic theory.

Make your own teaching behavior rational, standardized and scientific, and enrich educational theory with your own practice. Only in this way can we be comfortable in the process of education and teaching. Make full use of superior resources and actively participate in school-based teaching and research. Teaching and research group or grade group is the place where teachers carry out teaching and research activities, which plays an active role in helping backbone teachers communicate with other teachers, preparing lessons, correcting homework, discussing problems and exchanging ideas. The teaching and research group constructs the micro-psychological environment of professional activities, which plays a decisive role in the mood and state of mind of key teachers. The collective training level established and supported by the members of the teaching and research group determines the relationship and psychological atmosphere among the members of the teaching and research group.

Every collective teaching and research activity of the teaching and research group is an opportunity for key teachers to learn. At the same time, backbone teachers can discover the unique teaching art of other teachers: how to create a language atmosphere to stimulate students' interest in learning, how to close the distance between themselves and students with affinity, how to satisfy students' thirst for knowledge with profound knowledge and solid foundation, and how to create a passionate classroom teaching environment. In these learning processes, backbone teachers can find them as long as they look hard. 3. Action research of experience and reflection Modern teaching concept advocates action research of experience and reflection, which can not only realize teachers' professional growth in the shortest time, but also help teachers break through the platform period as soon as possible.

In daily teaching activities, backbone teachers should give full play to their subjective initiative, strengthen their independent practical activities, often think about new problems in educational practice, explore new ways, and analyze what they think in educational practice, which will benefit endlessly over time. Writing teaching postscript is a good way to help backbone teachers grow up in constant reflection. In addition, we should often discuss with our peers and listen to students' evaluation of their own education and teaching practice, especially their feedback.
