Senior one faces class. Facing the freshmen who have just entered the high school stage, it is particularly important to have a good first class in high school. Freshmen who have just entered the first year of high school are completely unfamiliar with the new learning environment, full of curiosity about high school learning, and full of imagination and expectation for new teachers. Faced with such students, we should make full preparations and have a good first class. The first is psychological and physical preparation. After a long or short summer vacation, teachers' life rules are different from those in normal work. In order to better enter the working state, it is necessary for us to adjust our work and rest time to synchronize it with the work and rest during normal work. At the same time, you can conceive your own class in advance and prepare lessons for yourself by looking for information on the Internet. Preparing lessons should prepare students for learning, so it is necessary for us to get the student roster from the class teacher and get to know the students and classes. If you can remember some students' names and say them in class, it will be a great surprise for students. Prepare lessons adequately, impart knowledge accurately and vividly, and never make mistakes. We should cherish the first impression in students' hearts. For example, if an English teacher is the head teacher, he writes a notice in English on the blackboard before the students formally attend class. As a result, the English spelling of "Wednesday" was wrong. After he found and corrected it, he stood in front of the blackboard and thought for a long time. Afterwards, students' evaluation of the head teacher and English teacher will be greatly discounted, which is precisely the result of the teacher's inadequate preparation and too casual performance. We can't expect teachers not to make mistakes, but we must avoid low-level mistakes. We must pay attention to the teacher's own image in the first class. Teachers' words and deeds, clothes and dresses will leave a deep impression on students' minds. What kind of image do you want to leave in students' minds? It is best to give students this impression in the first class. Or knowledgeable, or youthful and active, or calm and wise, or bohemian and so on. Your words and deeds will convey your personality characteristics to the students. We don't have to and can't change our personality because of students, but in general, the first class should be friendly and approachable to students, and don't let students stay away from you, because only teachers can believe it. The content of the first class can be colorful, and I believe every teacher will go straight to the new class without starting the class. It is necessary for us to improve the understanding between teachers and students. Teachers should introduce themselves, and it is best to let students remember your name and person immediately in a humorous way. We can also ask students to introduce themselves. In this self-introduction activity, the distance between teachers and students can be narrowed, and the characteristics of students can be recorded when students introduce themselves, so as to get close to students and understand them as soon as possible. The content of the first class is not only to improve the understanding between teachers and students, but also to make students fall in love with the courses you teach. Interest is the best teacher, and interest needs to be cultivated the day after tomorrow. In the first class, you should give full play to your talents as much as possible to make students fall in love with you. Chinese teachers can introduce beautiful poems, couplets, tongue twisters and wonderful short messages into the classroom, so that students can appreciate the beauty of Chinese learning. Mathematics teachers can connect boring numbers and formulas with mathematicians' growth stories and scientific and technological achievements, so that students can appreciate the profoundness of mathematics. And chemistry, biology and other courses can find examples in production and life, so that students can feel that this knowledge is actually around us. As the first class for junior high school students to enter senior high school, it is necessary for us to guide students' learning methods and standardize their learning behavior. It is necessary to clarify the difference between junior high school learning and senior high school learning, and put forward clear learning requirements for students according to the subject content, so that students can have rules to follow. Let students learn according to the requirements from the beginning, which will help students enter the learning state faster and improve learning efficiency. As the first class, we should try our best to make various forms of classroom teaching, make exquisite courseware, introduce music and movies, and let students participate in activities. In short, the first class should make students fall in love with your course and your teacher. The first class is only the beginning of classroom teaching, and a good beginning is half the battle, so it is necessary for us to take it seriously. As long as you have the enthusiasm to take your work seriously, you will definitely take every class seriously in the future.
