Hello, first of all, congratulations on becoming a high school history teacher. Being a teacher is a necessary condition, and a noble teacher's morality is the first condition to become a qualified teacher. This is the foundation of being a teacher. Secondly, I need to be familiar with the teaching materials and prepare a lot of media courseware to make the teaching ideas clear and coherent, and rehearse them repeatedly in my mind. Then establish a good personal image and form a harmonious atmosphere between campus and classmates. Learn and consult from colleagues with an open mind to learn from each other's strengths. Bold practice, courage to innovate, careful study of textbooks, discussion of teaching methods and flexible use of teaching means are effective methods to achieve teaching results. Treating students will inevitably have such shortcomings. At this time, we should not blindly abandon and blame, but should deal with it in a more mature and rational way. It is irrelevant to tolerate part of it. It doesn't mean that students have shortcomings and we will kill them with a stick. Everyone has his own advantages. At this time, we should be good at discovering the advantages of students, and give affirmation in time, and even expand the advantages, so as to cultivate students' self-confidence and promote their development. Give high recognition to students even a little progress, and even praise and encourage them in class many times. In this way, students' small progress becomes great progress. Pay more attention to students. No matter in life or study, we should give necessary care and help. Teachers should spend time talking and communicating with students and work together with students to shorten the distance between teachers and students. Respect students' personality, understand students' personality, trust students, care about students, unify strict requirements, pay attention to students' individual differences and treat them differently.
