What is a topic?

Topic teaching is a teaching and research activity, an effective way of teaching and learning, and an effective way to promote teachers' professional development and students' learning. Topics include questions from students and teachers. Teachers' thematic exhibition is a kind of educational research exhibition and discussion activity similar to lecture exhibition, which is the continuation and innovation of lecture exhibition and the deep-seated exhibition after preparing lessons. It can cultivate students' problem-solving habits and thinking quality, improve students' problem-solving ability, make students develop the study habit of "speaking, thinking, doing and reflecting" and strive to improve their problem-solving ability. 2. It helps to improve students' problem-solving ability. Students ask questions, which is a learning method. By talking about problems, they learn to solve this problem, draw inferences from others, learn to solve a class of problems, and know the theoretical knowledge contained in this problem. By talking about topics, we can cultivate students' thinking habits and thinking quality in solving problems, improve students' ability to solve problems, cultivate students' learning habits of "talking about topics, thinking about topics, doing topics and reflecting", and strive to improve students' mathematical literacy. Students' speaking and asking questions is conducive to changing teachers' concept of education and teaching, cultivating students' innovative consciousness and thinking, cultivating students' spirit of dare to explore and innovate, and promoting teachers to improve their education and teaching level. When teachers speak, they reflect their profound knowledge of educational theory, their mastery of subject knowledge, their ability to understand problem-solving methods, and their exploration of teaching forward-looking ideas, which urges teachers to integrate theory with practice. 4. Topic-telling activities that are conducive to creating a teaching and research atmosphere are often combined with classroom teaching practice activities. Give full play to the role of the topic teacher through "speaking". Through classroom practice, teachers' own educational theory has been refined, which also provides reference for others and exerts collective wisdom. The speaker should strive for the guidance of modern educational theory, and the evaluator should also strive for the theoretical basis of teachers' characteristics and successful experience. Both sides should form * * * knowledge around the same topic, so as to achieve the effect of learning from each other's strong points and get feedback from the speakers, so as to improve, promote and perfect their own teaching plans; Listeners get comparison, discrimination and reference from it, gain benefits from case argumentation and theoretical nourishment, and create a better teaching and research atmosphere. Third, the steps of talking about the topic The first step for the teacher to talk about the topic is to say the proposition. Indicate what level of ability the test questions belong to, what level of perception, understanding, analysis, application and transfer (different disciplines have different views on the level of ability), whether the knowledge and ability examined are low-order thinking or high-order thinking, whether the difficulty of the whole test paper is easy, medium and difficult, and the key point is to distinguish which group of students-it would be better if there are relevant statistical data such as the degree of discrimination of the test paper. Step four, guide the students to answer. For example, guide students to pay attention to answering questions according to scores; Guide students to learn the consciousness of finding collection points according to material cultivation; Guide students to develop the corresponding habit of answering questions. The fifth step is to expand the value. Explore the extended value of test questions. Expand migration, or popularize the law of solving this problem. Specific operations can change the corresponding conditions of the test questions and form new variant test questions; Or find similar problems. Students say that students should include the following contents: tell the general meaning of the topic, especially explain the known conditions and problems of the topic, and pay special attention to the hidden conditions in the topic; Tell the knowledge points involved in the topic; Say the solution to the problem; Tell the steps to solve the problem; Say the format and expression of the solution; Talking about the thinking method of applied mathematics: talking about other solutions, the optimization and change of solutions and the general popularization of conclusions; The summary of the problem solving, the source of the problem, the background and the relationship between the knowledge before and after, and the special attention and rigor in solving the problem. The purpose of "competition" is to promote teachers' research on teaching materials, exercises and college entrance examination questions through competition, so as to grasp the direction of teaching materials and college entrance examination questions more effectively, play the role of examples, exercises and college entrance examination questions in teaching materials, improve the pertinence and effectiveness of classroom teaching and promote the improvement of teachers' professional level.
