The teaching mode of "learning first and then guiding, self-help and mutual assistance" is the first learning goal for teachers to reveal classification in the teaching process; Secondly, through open learning, students are guided to find problems and ask questions independently, including questions previewed before class and the collection of relevant materials; Thirdly, through group discussion, discussion and report, harmonious teacher-student interaction and student-student interaction are formed, and the information exchanged is fed back in many directions, which produces teaching shock and solves difficult problems; Finally, the classified learning objectives are successfully displayed, which guides students to further think and explore, extending from in-class to out-of-class, thus improving the classroom learning effect and developing students' various abilities.

The core idea of this model is "learning before guiding". "Learning first" means that students preview the course content according to the learning plan formulated by the teacher, make a structural analysis of the course content and preset questions, and conduct independent cooperative inquiry learning around the text. "Post-guidance" refers to teachers' questioning, guidance and guidance on unresolved issues in students' independent cooperation.

"Learn first, then guide yourself" contains several key words, namely preview, mutual assistance, display, feedback and extension.

Preview: that is, learn first, which is the first key link of the "learn first and then guide" model. The key to learning before guiding is to learn first, that is, to preview with goals and quality. Through preview, students have an understanding of knowledge, a grasp of problems, self-confidence and the initiative to speak, and their enthusiasm, initiative and creativity in classroom teaching can be fully demonstrated. The whole classroom will undergo fundamental changes.

Mutual assistance: that is, cooperative learning between students, teachers and students, guiding students to ask questions, guide, inspect, inspire, encourage and supervise each other, implementing the teaching strategies of "teaching soldiers with soldiers" and "training soldiers with soldiers" in general, and launching harmonious competition and cooperation with each other; In this link, the teacher is both a director and an actor.

Display: it is the display of students' basic knowledge and skills, students' language, students' learning methods, students' knowledge internalization process and thinking process, or it is a display of exploration spirit.

Feedback: Instruct students to revise classroom tests face to face in class. There are many forms, which are integrated with detection.

Expansion: refers to extending the learning content from in-class to out-of-class, so that students can learn by analogy.
