The implementation of the teaching mode of "learning plan" can be divided into the following links: 1. Instruct students to preview carefully according to the learning plan-preview before class is an extremely important link in the teaching method of "learning plan", which not only fully embodies the learning guidance function of learning plan, but also is the key link to realize "subject first". The teacher will send the study plan to the students in advance. Based on the study plan, students will actively read textbooks, consult materials and explore experiments around the learning goals and difficulties, so as to gain knowledge and improve their active learning ability in the attempt. For example, when learning the chemical properties of alkali, students can compare and preview because they have already learned the properties of acid. 2. According to the feedback of difficult information, discuss and solve doubts-based on cases. In class, teachers should organize students to preview and communicate before class to understand the main problems existing in students' preview. Establish students' dominant position, and students will actively seek help from others when they encounter difficulties in their attempts. As a result, learning has become my own demand, from "asking me to learn" to "I want to learn", and I rely on cooperation to explore and solve problems. Teachers can guide students to inspire each other and digest individual doubts through individual speeches, group discussions, class dialectics and other discussion methods. 3. Teachers are good at lecturing and enlightening me-in case study class, teachers can accurately grasp the learning situation and give lectures and guidance according to the information feedback of students' autonomous learning. Accurately speaking, for difficult problems, teachers should aim at their doubts, clarify their thinking, reason, take the problem as a case, and deduce the general law of solving problems from individual problems, so as to achieve the teaching purpose of giving inferences by analogy. For example, when studying the reaction between sodium hydroxide and hydrochloric acid, students can be guided to deduce the principle of acid-base neutralization reaction. In this way, under the guidance of teachers, students can sum up the internal relations between old and new knowledge points and build a knowledge network, thus cultivating students' analytical and comprehensive abilities. Guidance, in the process of students discussing and solving doubts, teachers participate in it, and give timely guidance, inspiration and guidance. 4. J. summary. Form a network-after promoting learning by case, let students summarize the key contents, laws, ideas, problem-solving methods and skills of this lesson, comb the knowledge into lines, form a network, and deepen their memory; Teachers timely summarize the knowledge points that are easy to make mistakes and mix up, thus playing a guiding role in students' learning. For example, when learning the reaction between acid (acidic oxide) and alkali (basic oxide), students are often asked to sum up and form a material network. 5. Standard training in the classroom, knowledge transfer and expansion-teachers can use the typical exercises designed in the study plan to train students. The teacher collects the answer information, then shows the reference answer, group discussion and teacher's comments, focusing on the idea of solving the problem. For students' problems, teachers can supplement exercises in time to give students the opportunity to internalize. 6. Arrange after-school exercises or extracurricular practical activities After-school learning activities can design 1-2 inquiry questions pointing to the learning content of this class, or design a special practical activity combining learning content with real life. Designing after-school learning activities on the study plan is not to replace after-school exercises, but to assign tasks and guide students' learning, so as to reflect the integrity of the learning process and promote the integration of learning activities before, during and after class. The superiority of "planned learning" teaching mode is 1. It has aroused students' enthusiasm and cultivated and improved students' autonomous learning ability. The teaching of "learning according to plan" shifts the center of classroom teaching from "teaching" to "learning". Students really become the main body of learning, and they are affirmed and praised by teachers through discussion and summary in class, thus stimulating students' learning motivation and mobilizing their learning enthusiasm. 2. Improve the effect and quality of classroom teaching. Students have mastered the contents of textbooks through self-study. Therefore, the classroom atmosphere is lively, and there are many people who raise their hands to answer questions, and there are many people who ask to perform on stage, and the students' desire for self-expression is enhanced. In this way, students not only have a thorough understanding of what they have learned, but also have a deep impression, thus improving classroom efficiency. For students with learning difficulties, they lack interest in learning and their learning methods are not good. The teaching feature of "case-based learning" is to attach importance to the cultivation of students' interest in learning and the guidance of learning methods, which is conducive to the counseling of students with learning difficulties. Therefore, "learning plan guidance" effectively promotes the improvement of students' learning efficiency and teaching quality. 3. The professional level of teachers has been improved. "Learning plan guidance" requires teachers to prepare lessons not low, but high. Because this requires teachers to arrange and organize teaching according to the actual situation of students in the classroom, it is difficult to design in advance, which requires teachers to master the teaching materials without preparation, so as to be accurate, comprehensive and vivid. Therefore, teachers should devote themselves to studying teaching materials, understand the learning situation and improve their professional level. In a word, the teaching mode of "learning by learning plans" takes autonomous learning as the guiding ideology, and organizes teaching by using learning plans, which fully embodies students' dominant position in the learning process and enables students to master the initiative in learning. This new concept of teaching reform strategy can promote the change of teachers' teaching behavior, attach importance to the infiltration of chemistry learning methods, integrate teaching and learning, and improve the enthusiasm of learning chemistry at school, thus improving academic performance.
