It should be standard, smooth and of moderate size.
The "circle" in geometry cannot be written as "garden"; "Integer" cannot be written as "positive"; The problem-solving format should be standardized, and the font should be neat and easy to identify. The teacher should also determine the font size of the blackboard according to the size of the classroom, the number of students and the intensity of light to ensure that every student can read it clearly.
The key points should be highlighted and the layout should be reasonable.
The blackboard writing is not extracted from the textbook, but the essence of the textbook. Its content should generally include the following parts: subject name, important concepts, main formulas, basic graphics, typical examples, matters needing attention and homework. The words, formulas or symbols on the blackboard should be refined and accurate. For the key points, it is advisable to add fonts or colored pens to make them stand out, so as to increase the aesthetic feeling of the board.
In the overall layout of the board, there should be a division of the main and auxiliary parts, and the blackboard is generally divided into several large pieces. The main board writes subject names, important concepts, main formulas, basic graphics, etc. Assist in writing typical examples on the blackboard, matters needing attention, assign homework or leave it to students to perform. The arrangement of blackboard writing should be designed when preparing lessons, and the main blackboard writing should not be erased at will. At the end of the lecture, we should strive to make the whole board clean and clear, focused, properly spaced, patchwork, harmonious and beautiful, and overall beautiful.
We should combine speaking and writing at an appropriate speed.
In classroom teaching, according to different teaching materials and class types, we should adopt the methods of speaking before writing, writing before speaking or writing while talking. We should be good at grasping the opportunity to make the bilateral teaching activities between teachers and students cooperate tacitly. When you encounter some difficult definitions, you can write them on the blackboard first and then explain them word by word; Some easy properties can be summarized or deduced first, and then written on the blackboard; For example, some geometric arguments need to arouse students' thinking, so they can be written while talking and gradually developed.
To illustrate, vivid and eye-catching.
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 the artistic level in this field.
