Point 1: Write on the blackboard to the point. Writing on the blackboard is as expensive as explaining. As the ancients said, if you have less, you will get it, but if you have more, you will be confused. The blackboard writing should be "few books" and "excellent works", and the blackboard writing should focus on the books with ideas and key points, and play the role of "making the finishing point" and "reading the outline"
If the blackboard books are used too much or mixed, there will be a phenomenon of "A, B, C, D, 1234" opening a grocery store on the whole blackboard, which will make teachers and students suffer a lot and the effect is very poor.
Point 2: pertinence, combination of reality and reality. Blackboard writing is a supplement to the teaching materials. It is necessary to make it easier for students to copy through teachers' relatively complete and systematic blackboard writing. In addition, it is necessary to combine reality with reality.
Some contents need to be written on the blackboard word by word, and some contents don't need to be written on the blackboard, so they are omitted and hidden in the blackboard. Students can understand them by the teacher's words or push them down according to the context. This not only saves time, but also helps to cultivate students' note-taking ability.
Point 3: Careful design and reasonable layout. The general "mode" of blackboard writing is to divide the blackboard into main parts and auxiliary parts. The main part is a systematic blackboard writing for teaching the content of the textbook; the auxiliary part is flexible and often used to write words, words, concepts and old knowledge related to this lesson.
If you plan carefully, under normal circumstances, it is enough not to wipe in class, so a blackboard is written in one class and the class is over. After class, others can know the internal logical structure and teaching process of the knowledge system taught in this class at a glance by looking at the blackboard.
The fourth point: be correct and tidy, and pay attention to aesthetic principles. In mathematics classroom teaching, we should not only write words, formulas and symbols on the blackboard, but also draw pictures. Bright and concise mathematical figures, coupled with concise text descriptions, can deepen students' understanding of teaching materials.
The combination of numbers and shapes is not only necessary for the content of mathematics textbooks, but also necessary for intuitive teaching methods. Never doodle at will. Writing on the blackboard is an important means of classroom teaching and a necessary basic skill for every teacher. In order to improve the quality of classroom teaching, we must strive to improve this art. ..
Eighth: thought-provoking, stimulate interest in learning. Writing on the blackboard should be conducive to the development of students' intelligence, unique and thought-provoking. To make writing on the blackboard enlightening, we should not write on the blackboard for the sake of writing on the blackboard, but use it properly. Teacher Wei Shusheng uses five forms of blackboard writing to stimulate students' interest in learning: font changes; Deliberately writing typos, changing expressions, charts and pictures; Let the students write on the blackboard.
