The teacher took out a white chalk from the box and wrote a few lines of neat handwriting on the blackboard. Important knowledge points were highlighted with chalk of different colors... The sound of the book was loud and the chalk was "dada". Under the teacher's pen, knowledge beads were formed into lines, and in the students' hearts, knowledge saw both wood and forest. This kind of scene was once seen daily by many people during their student days. In recent years, with the continuous deepening of the application of information technology in classroom teaching practice, there have been fewer teachers who write on the blackboard. Some people may ask, in the information age, does classroom teaching still need blackboard writing? Of course, the answer is yes, which can be seen from the fact that teachers who write beautiful blackboard writing often "go out of the circle" on the Internet. People praise the beautiful blackboard writing because it showcases teaching skills and the personal charm of being a teacher. Recently, the reporter interviewed three teachers who gained fans through blackboard writing, and the three foot podium recorded their educational aspirations. At the moment when the chalk projection screen in the classroom suddenly turned black, Cheng Siyu felt a real sense of nervousness. He is a young teacher from the School of Marxism at Tianjin University. At the beginning of this lecture on "Outline of Modern and Contemporary Chinese History," there was a sudden power outage in the classroom, and Cheng Siyu still had dozens of pages of PPT to talk about. After calming down for a few seconds, he walked towards the blackboard and picked up the box of chalk that had fallen into dust. With solid preparation and excellent blackboard writing, the class was successfully completed. Years later, Cheng Siyu is still very grateful for the circuit failure he encountered in his first year of teaching. The power outage class told me: real skills are in the mind, not in the USB drive. ”He said. At Tianjin University, Cheng Siyu's classes are very famous, among which the most outstanding one is his hand drawn schematic diagram of the Red Army crossing the Chishui River and the Jinsha River on the classroom blackboard. We go back to 1935, and this picture shows the border area of Sichuan, Yunnan, and Guizhou provinces, "Cheng Siyu said, pointing to a blue chalk drawn river." This river winds through the mountains and this is the Chishui River. "The map depicts the Red Army's various stages of advance in different colors, with sharp arrows piercing through the enemy's encirclement. The students in the audience were focused and took out their phones to take pictures of Cheng Siyu's blackboard writing. Some even posted them online, and Cheng Siyu quickly gained a lot of followers. When asked why he came up with the hand drawn painting of the Four Crossing Chishui River, Cheng Siyu said, "The engineering characteristics of Tianjin University are very distinctive, and professional knowledge involves a lot of calculations. The usage rate of blackboard writing is much higher than that of humanities. This gave me a great inspiration, and I tried to apply blackboard writing to daily teaching." In Shandong, Yuan Xiao, a geography teacher in the second year of high school at Jinan University City Experimental Senior High School, also sparked public discussion due to his beautiful blackboard writing. In a classroom video with hundreds of thousands of likes, it is recorded that Yuan Xiaomiao's pen "paints": his arm twists and turns, drawing a round earth; Cold and warm air masses converge, and the front is covered with clouds, mist, and raindrops; On the map of world ocean current distribution, the contours of continents and oceans are clear and bright... With pen and brush strokes, the three-dimensional blackboard writing often makes Yuan Xiao's students reluctant to clean the blackboard. For geography teaching, especially natural geography, blackboard writing has unique advantages in displaying knowledge points such as spatial models, atmospheric circulation, and geological movements. On site drawing can also respond to students' questions in real time and demonstrate the complete process of thinking deduction. ”Yuan Xiao said, "In the new lesson stage, I use more multimedia courseware, and blackboard writing is mainly used during the review stage. The key is to decide the teaching format based on different grades and teaching content." Courseware or blackboard writing? Interviewed teachers said that in the technology wave, blackboard writing, which seems to have become a "supporting role", sticks to the teaching temperature that cannot be replaced by coding. However, this does not mean that there should be a comparison between blackboard writing and multimedia courseware. Both have their own strengths and complement each other. In recent years, China's digital infrastructure has significantly improved. According to the data, as of February 2023, the Internet access rate of primary and secondary schools (including teaching points) nationwide has reached 100%, and 99.5% of schools have multimedia classrooms. The unique advantages of multimedia teaching tools are obvious: the courseware has a large capacity, is more flexible, images and videos can be inserted between texts, and some abstract concepts can be made into animations for demonstration. Courseware not only improves classroom efficiency, but also adds fun and facilitates teachers' repeated use. However, as teaching aids become more comprehensive, PPTs become more and more "cool", and content becomes richer, some people worry that children who grow up in front of screens in the digital age may lose some sense of realism, lack interaction between teachers and students, and affect the classroom atmosphere. Some people are also concerned that the overwhelming amount of courseware and "information overload" will affect children's learning effectiveness, and the massive content in PPT makes it difficult for students to distinguish the key points. Professor Huang Fanglin from the Department of Mechanics at the School of Civil Engineering, Central South University has been writing on board for nearly 30 years. He told reporters that he had also tried using electronic courseware in his early years, but later found that his teaching method of writing on the blackboard in class was more effective. The discipline of civil engineering involves many courses, such as mechanics, with many formula derivations. If these contents are not carefully designed for teaching and the knowledge from the textbook is directly transferred to the PPT, students sometimes have no impression at all. I wrote on the blackboard and deduced it step by step. The complete thinking and analysis process is clear to students, which helps them better understand the basic principles of mechanics, rather than just memorizing the conclusions. When playing courseware, some students may become dependent on 'taking courseware', unwilling to use their brains to think or take notes in class. After taking the courseware, they may not really be able to read or learn it. ”Huang Fanglin said. Board writing condenses teaching ideas, and polishing board writing helps teachers improve their teaching abilities. In Yuan Xiao's opinion, excessive reliance on courseware can lead to a decline in teachers' ability to prepare lessons. Only by combining standardized teaching with personalized teaching can we better improve the quality of teaching. Board writing is an instant visualization of ideas, and not only that, students can also participate in the drawing and editing of board writing, enhancing their sense of classroom participation, "he said. Although praised by students as the "soul painter", Yuan Xiao always hopes that technological development will bring more possibilities to geography classrooms. In the future, with the development of VR and technologies such as 5G and 6G, geography classes may become more interesting, enjoyable, and immersive, which is a major trend in the future. ”Yuan Xiao said. After the start of the fall semester last year, Tsinghua University held the 2024 Chalk Board Competition for faculty and staff in search of the "best teaching solution" in the information age. This competition has been held continuously for 8 years. One by one on the blackboard, the strokes are strong and powerful, and the strokes are graceful and elegant. Between the lines, there is a love for education and respect for the classroom. How to cleverly combine blackboard writing with new media technology to find the "optimal teaching solution"? In Cheng Siyu's opinion, in teaching practice, we should adhere to the combination of blackboard writing and courseware - blackboard writing is used for framework sorting and key reinforcement, and multimedia courseware is used for historical material display and improving teaching efficiency. To increase the visibility of ideological and political courses, the example of the Four Crossing Chishui Board Script proves that visual teaching can effectively attract students' attention. At the same time, the Party history class involves a large number of historical materials and images, and the courseware can provide sufficient information, "he said. In recent years, Cheng Siyu has put in a lot of effort into researching courseware. He hopes to prove through practical actions that blackboard writing and courseware cannot be neglected, and the two must be used comprehensively. I pay great attention to the use of colors in the courseware. For example, in the course "Outline of Modern and Contemporary Chinese History", we will talk about five periods, and I will choose different colors for each period in the courseware. Different colors need to reflect the background colors of different times. ”Cheng Siyu said. The teaching methods have changed and updated, but the educational core of educating people has never changed. Choosing any tool ultimately serves this goal. The decades long dedication and research of teachers have condensed into a deep and easy to understand approach in the classroom. Huang Fanglin said that besides not using PPT to give lectures, he also doesn't have the habit of bringing lesson plans in class because all the knowledge and textbooks have already been integrated into his mind. After class, if the blackboard is erased, it will be covered with new content. However, those knowledge and principles will be imprinted in the hearts of students for a long time along with the back of the teacher, recording the neat blackboard work and the warm teacher-student relationship as yesterday.
