? The definition of "preparing lessons" in Sogou Encyclopedia is to choose appropriate expression and order according to the requirements of subject curriculum standards and the characteristics of the subject, combined with the specific situation of students, so as to ensure students' effective learning. Preparing lessons is the premise of a good class and the basis for teachers to give full play to their leading role. As a teacher, preparing lessons is a lifelong matter. In order to better serve students and classrooms, the thinking and preparation of lesson preparation is accompanied by the teacher's life.

As a young school, Chengxi has a group of young teachers. Alliance development and common progress are the foundation. As the most important form of lesson preparation, collective lesson preparation should obviously become the main position for the growth of teachers in Chengxi. In practice, the author finds that mind mapping plays an important role in classroom teaching, teacher growth and thinking development. At the same time, the openness, inclusiveness and autonomy of mind mapping give us a lot of room to play. I believe that if we stick to this form, we will certainly benefit from teachers' usual study and continue to teach in the classroom.

? In order to let everyone understand mind map, the author uses ppt to explain with examples: mind map is also called mind map. By the famous psychologist and educator Tony? Bozan invented it. Simply put, mind mapping is to draw your own ideas by drawing pictures. It is a thinking mode that combines the concept of whole brain. Its main content is painting rather than painting. Generally, the radiation curve is drawn with the north as the center, and more curves can be drawn at the end of the curve. It can write any understanding of the learning object by giving full play.

? The use of mind map is simple, only some pictures and lines of different colors are combined, and anyone with a certain learning foundation and life experience can learn to use it. Once you master this method, you can improve his thinking ability and level in a short time and tap his thinking potential, because mind mapping is simple, fast and efficient. At the same time, mind mapping gives people the greatest openness and flexibility of thinking, so it is very inclusive, can stimulate people's rich association and has very strong personalized characteristics. A comprehensive and systematic description and analysis of the problem is very helpful for people to think deeply and creatively about the studied problem, and is beneficial to anyone who applies it in theory, and its application field can be almost unlimited. In a word, making a flexible mind map can play a considerable role in work and study in many fields with these unique characteristics.

? In order to let everyone know more about mind mapping, the author explains seven applications of mind mapping: for example, when we choose a monitor, we can use mind mapping to sort out and compare the advantages and disadvantages, specialties and other related contents of alternative students, and then make a decision; Another example is "notes". Teachers usually read much more than other occupations, but with the increase of age, their memory declines seriously. Simple reading and memory effect is very poor. Reading notes with the help of mind map can obviously improve the reading effect. There are also students' composition application, review, exhibition and exchange, teaching design, activity plan and so on. , can improve memory, deepen the understanding of knowledge, clarify complex ideas, stimulate creative ideas, and help children learn happily.

? Next, the author introduces eight basic forms of mind mapping, and lists the functions of various forms in the teaching process of major disciplines or teachers' own learning and growth. For example, if the double bubble diagram is used to compare similar concepts, the bridge diagram can be used not only for oral arithmetic practice, letter combination word practice, but also for word-making and sentence expansion practice. Various forms of expansion have given you more inspiration. Finally, the author shows some middle school students' works in previous teaching, and shows the students' real gains with actual effects.

? Teacher Zhang Jianyue of People's Education Society pointed out that three understandings (namely, understanding mathematics, understanding students and understanding teaching) are the cornerstones of teachers' professional development, the fundamental guarantee of the quality of mathematics teaching, and the magic weapon for teachers to "change with the constant" in the tide of educational reform. The author believes that not only mathematics, but also the teaching of other subjects can not be separated from three understandings: understanding the subject, understanding the textbook and understanding the students. Therefore, before carrying out education and teaching, we need to sort out the curriculum standards of our teaching subjects and the textbooks of this book, deeply understand them in the interpretation, and grasp the textbooks of all grades as a whole in the communication between different grade groups, so as to realize the targeted strengthening of textbooks and teaching and better serve the development of students.

? Each subject group sits around to discuss and communicate, sort out ideas, draw the curriculum standard map and teaching material analysis map of each study section, and learn from each other's strengths in mutual display. All the groups worked together and soon presented wonderful works. I hope you can not only try to apply it yourself, but also apply mind mapping in the teaching process soon. We will continue to carry out relevant training, exchanges and activities in the future.
