So how to evaluate the class? As a school, it is inseparable from attending classes and evaluating classes in daily education and teaching. The most important thing in every school is the quality of education. It is the lifeline of school work. Every teacher is committed to improving the quality of teaching. Therefore, a series of listening and evaluation activities are under way. Listening and commenting is the most direct, concrete, frequent and effective method to study and improve the quality of classroom teaching. It is an important measure for our front-line teachers to learn from each other, learn from each other and study teaching. We have such materials in our information technology textbooks. Bernard Shaw said, "You have an apple, and I have an apple. After exchanging with each other, it is still an apple;" If you have an idea, so do I. After communicating with each other, everyone has two ideas. " Therefore, the activities of listening to lectures and evaluating classes among teachers can achieve the purpose of exchanging teaching experience and learning from each other. Listening and commenting has several functions: First, teaching and research functions. In fact, attending lectures and evaluating classes is not only a teaching and research activity, but also a scientific research activity. It builds a bridge between teaching practice and teaching theory. It is not only a process of verifying theory and guiding practice, but also a process of practical operation and sublimation into theory. We can learn and absorb a lot of teaching theories, experiences and advanced teaching reform information in class attendance and evaluation, and apply them to teaching. You can also sum up your own experience to form a theory. In this way, teachers' teaching professional quality will be greatly improved. Secondly, encouraging the development of functional listening and evaluation courses plays an extremely important role in broadening teachers' horizons, encouraging teachers to make progress and developing teachers' teaching ability, and can guide teachers to take the road of spiraling teaching ability. Third, the role of teaching diagnosis is to give targeted lectures, and make a comprehensive analysis of the class when evaluating the class. In the process of analysis, on the basis of affirming the advantages, the existing problems are emphatically analyzed. It is necessary to make a perspective from the aspects of teachers' learning textbooks, handling textbooks, understanding students, choosing teaching methods and designing teaching procedures, and analyze the reasons for the problems. Finally, specific suggestions for improvement are put forward. This is a process of diagnosis, diagnosis and treatment. The fourth is the communication and coordination function. It can coordinate the communication ability between teachers, between teachers and students, and between teachers and leaders. The characteristic of information technology class is that students are trained in information technology from different angles. Listening and evaluating information technology courses should not only evaluate the teaching objectives from the routine; Comments on the processing of teaching materials; Comment on teaching procedures; Comment on teaching methods and means; Comment on teachers' basic skills; Comment on learning and fingering; Comment on the relationship between teachers and students; In addition to evaluating the teaching effect, we should also pay attention to evaluating two aspects: first, evaluating students' ability training. The ultimate goal of our information technology course is to cultivate students' information literacy, which runs through every bit of every class. In every class, students should not only be taught to use this skill, but also be made to understand why they should master this skill, how to use this skill in life and study, and how to use the skills they have learned to solve problems in the future. Therefore, we should pay attention to this aspect when listening to and evaluating information technology courses. The second is to evaluate students' learning. Information technology courses should have higher evaluation requirements for students. Whether students actively participate in the learning process: active participation in learning activities is manifested in listening carefully, thinking positively, expressing opinions boldly, daring to question and ask questions, actively doing experiments and actively cooperating with classmates. How much do students participate in learning activities? There are a large number of students participating in learning activities, and there are various ways to participate in learning activities. In addition to regular reading, writing and practice, organize group discussion, cooperative learning and inquiry learning in a timely manner, and participate in learning activities for a moderate time. The teacher's explanation should not exceed 1/2, and the students' autonomous learning time should not be less than 1/3. Whether students' cooperative learning and inquiry learning are effective: there is a clear division of responsibilities in cooperative learning and good communication between peers. In inquiry learning, students can independently discover problems from a given situation, go through the inquiry process through experiments, operations, investigations, information collection and communication, acquire knowledge, improve skills, master methods to solve problems, and gain emotional experience. In a word, effective listening and evaluating classes is a good way for each of our teachers to improve themselves.
