According to the People's Daily, after the start of the autumn semester this year, Tsinghua University held the 2024 Chalk Board Writing Competition for faculty and staff, which has been held continuously for 8 years. From classic poetry and literature to scientific formulas, the blackboard writings written by teachers are either elegant and graceful, or powerful and vigorous, with deep respect for knowledge, love for education, and inheritance of culture between the lines. A netizen commented, "I can't bear to wipe off this kind of blackboard!" A chalk, two sleeves of fresh air, a three foot podium, and four seasons of cultivation. For many people, the teacher's powerful blackboard writing and the rustling sound of chalk rubbing against the blackboard are unforgettable memories of their student days. In recent years, teachers' handwritten blackboard writing has occasionally appeared on hot searches. From elementary school teachers writing chalk characters that look better than print, to university professors persisting in 26 years of handwritten blackboard deduction formulas; From the ideological and political education teacher's hand drawn diagram of the Red Army crossing the Chishui River, to the medical professional teacher's stroke by stroke depiction of the human skeleton... These clear, beautiful, and intricately designed chalkboards always resonate. While commenting on the exquisite blackboard writing, netizens also sighed that "there are fewer and fewer beautiful blackboard writing". "In class, chalk seems to have become a 'supporting role'.". Indeed, in the era of educational informatization, blackboard writing is no longer the only choice for teaching. According to data from the Ministry of Education, as of the first half of 2019, 93.6% of schools nationwide have multimedia classrooms, and 74.2% of schools have achieved full coverage of multimedia teaching equipment. Full media teaching tools have unique advantages, such as larger and more flexible "pre made" courseware capacity, and the ability to insert images and videos between texts. This not only improves classroom efficiency, but also adds fun and facilitates teachers' repeated use. However, there are also some hidden concerns behind this. For example, courseware passes by in a flash, students are overwhelmed, there is a lack of interaction between teachers and students, and the classroom atmosphere is dull, which affects the actual effectiveness of teaching; For example, some teachers neglect teaching design and directly transfer knowledge from textbooks to courseware, making it difficult for students to grasp the key points. However, some children feel that having courseware means everything is fine, and they are unwilling to use their brains to think and take notes in class, and their thinking ability cannot be exercised... A member of the National Committee of the Chinese People's Political Consultative Conference once proposed that schools at all levels and types should re-examine the importance of teachers writing on the blackboard and students taking notes, and should not overly rely on PPT. They should pay more attention to the cultivation of students' listening, speaking, writing, and summarizing abilities. For teachers, blackboard writing is dynamic and real-time. In the process of using blackboard writing for teaching, teachers can adjust the teaching pace according to students' reactions at any time. Moreover, blackboard writing is the condensation of teaching ideas, and constantly polishing blackboard writing can help teachers improve their teaching abilities. For students, if the blackboard is well-designed, it can turn complexity into simplicity and abstraction into intuition. The process of deducing along with the blackboard is also the process of internalizing knowledge in the heart, and this kind of "immersion" is indispensable. Not only that, neat and beautiful blackboard writing can also showcase the beauty of Chinese characters, which is beneficial for students to cultivate correct writing habits. I still remember when I was in elementary school, I met a Chinese teacher with a deep foundation in calligraphy. Watching her write chalk characters with flowing water on the blackboard during class, I felt ashamed of my "dog crawling character" for the first time. Later, I used the teacher's character as a model and began to practice calligraphy vigorously. In the future, information-based teaching methods may become more advanced and efficient, but this does not mean that blackboard teaching will become outdated. In fact, the relationship between blackboard writing and information-based teaching methods is not one of "you in, I retreat". If we can grasp the "degree" of multimedia teaching and use them together according to the teaching content and classroom reality, we may not be unable to achieve complementary advantages and achieve a teaching effect of "one plus one is greater than two". The chalkboard competition held by Tsinghua University has attracted countless netizens to "watch online". Behind this popularity, there is also an expectation that regardless of the era, chalkboard should be a basic skill essential for excellent teachers. Many years have passed, and the handwriting on the blackboard has become blurry, but the knowledge and principles written down one stroke at a time have been engraved into the life papers of generation after generation.
