A: Teaching mode refers to the relatively stable structure framework and activity procedures of teaching activities established under the guidance of certain teaching ideas or teaching theories. Teaching mode is not only the concretization of teaching theory, but also the systematic generalization of teaching experience. The commonly used teaching modes in China are: (1) transmission and reception mode: a well-known teaching mode widely used in the teaching practice of primary and secondary schools in China for a long time. Basic teaching procedures: stimulate curiosity, perceive teaching materials, understand teaching materials, comprehensively use them, and check and evaluate them. (2) Self-study-guidance mode: a mode in which students learn independently under the guidance of teachers. This teaching mode is based on the teaching guiding ideology of cultivating students' independent thinking ability and teaching students to learn, and is formed on the basis of practice and experiment. (3) Situational training mode: refers to a teaching mode that creates a teaching environment in which emotion and cognition promote each other in teaching activities, so that students can effectively acquire knowledge in a relaxed and pleasant teaching atmosphere and cultivate their emotions at the same time. In this model, teachers are the motivators and defenders of students' emotions. (4) Demonstration and imitation mode: it is a teaching mode in which teachers explain and demonstrate, and students participate in practice to acquire knowledge and skills. Teachers should pay attention to the explanation and demonstration of the principles, procedures and key links of behavioral skills. Because it is impossible for teachers to evaluate every student's practice of every movement and skill, we should pay attention to the mutual communication and observation between students. This model is especially suitable for teaching content aimed at mastering behavioral skills. (5) Try teaching mode: In teaching a new lesson, let students try to practice first, and then the teacher will explain it, that is, "practice before speaking", also known as "five-step teaching method", which was originally created by Qiu Xuehua, a math teacher in China. Basic teaching procedures: ① Show test questions; ② Teaching materials for self-study; ③ Try to practice; ④ Students discuss; ⑤ The teacher explained. (6) Target teaching mode: refers to a teaching mode that is guided by clear teaching objectives, driven by teaching evaluation, and centered on correction and reinforcement, so that most students can master the teaching content. Its theoretical basis is Bloom's mastery learning theory, educational goal taxonomy, formative evaluation theory and cybernetics principle. In this model, teachers are the providers of goals and the organizers of students' compliance. (7) Guided discovery mode: it is a teaching mode that focuses on solving problems, pays attention to students' independent activities and pays attention to the cultivation of thinking ability and willpower. It is a teaching model based on the procedure of "question-hypothesis-reasoning-verification" advocated by Dewey and Bruner, combined with the teaching achievements of some educators in China. (8) Concept acquisition mode: The goal of this mode is to enable learners to develop their thinking abilities such as induction and reasoning and master the methods of inquiry thinking by experiencing the formation of the concept principles they have learned. This model mainly reflects the view of cognitive psychology school, emphasizing that learning is the organization and reorganization of cognitive structure.
