Nowadays, with the extensive use of information technology, multimedia courseware has become an indispensable part of classroom teaching, and it is greatly favored. In contrast, the traditional slate has become a dispensable. However, the School of Data Science of Zhejiang University of Finance and Economics has an associate professor. For 35 years, he has insisted on teaching in the form of a full-board book, becoming a "classroom network red." Moreover, there are also colleges and universities to hold board design competitions from time to time, such as Tsinghua University, Shandong University of Technology, etc., also received the students' enthusiasm. Then, in the classroom teaching in the information age, how to balance the relationship between multimedia and traditional blackboards? Multimedia is "a big way" In fact, multimedia teaching in China has already begun to take shape in the 1980s, but it really started in the early 2000s. In this regard, Wang Hua, an associate professor of the School of Humanities and Social Development of Northwest Agriculture and Forestry University, has personal experience. “I started to work in 2001. At that time, the teachers basically relied on the blackboard, and a chalk class was the basic form of classroom teaching.†Wang Hua said that after a few years, the school began to build multimedia classrooms. “I was younger at the time, and it was the first batch of applications and learning to use multimedia teaching in the school. Later, there were more and more teachers using multimedia classes.†In the same period of Nankai University, the situation is similar. "But according to my memory, the liberal arts departments of Nankai University do not seem to have extensively promoted multimedia teaching around 2000. Most teachers use blackboard books to demonstrate teaching content, such as mathematics and ancient Chinese." Associate Professor, School of Literature, Nankai University Gu Feng said. At present, multimedia equipment at all levels and schools is used more and more widely, and Gu Feng is one of them. “In recent years, the proportion of projections in my teaching has increased, because the ancient Chinese classes in colleges and universities have been compressed, and there are only two classes per week. In a limited class, it is necessary to take into account the knowledge of exegesis, phonology, grammar, etc. In order to save time, I had to show some long paragraphs on the projection equipment. Sometimes I introduced ancient culture common sense, such as costumes and horses, and I also preferred PPT.†Gu Feng said. Moreover, in recent years, new concepts such as “Mu Classâ€, “Flip Classroomâ€, “Super Star Lecture Hall†and “Rain Classroom†have appeared. In Gu Feng’s view, “the concept of traditional classroom has changed a lot, and multimedia means in the future. Occasionally, the proportion of the occupation will increase." In a questionnaire survey conducted by a certain media a few days ago, this phenomenon that Gu Feng said was also confirmed. The survey was conducted for 2,000 people, 90.8% of the respondents confirmed that the schools around them were using multimedia teaching, and 64.1% of the respondents thought that multimedia teaching was effective. Then, in the context of the prevalence of multimedia teaching, is the traditional blackboard book really useless and even replaced? The traditional blackboard is heavy "white" Regarding this issue, Wang Hua is negative. “The book can better reflect the key content of the course and help the teacher to express his feelings.†Wang Hua said that when the teacher walks around or writes a book, the students’ attention will be more concentrated than watching the PPT alone. When watching TV, a advertisement is suddenly inserted. Moreover, the process of writing a book is also a process of embodying thinking. Students will also think with the teacher to better align the relationship between the various knowledge points, which is of great benefit to teaching. of". Wang Hua said that students must have thinking when they are in class. If the teacher just explains according to the PPT, then the student’s brain will be full and he will not be able to leave room for thinking. The blackboard just makes up for this. “It is like Chinese painting. The 'white space' on the classroom provides the classroom with a sense of rhythm. In this sense, the blackboard can also be said to be the 'white space' of classroom teaching. In this regard, Gu Feng also took it for granted: "The traditional teaching method of the blackboard is still necessary for its existence and will not be replaced by multimedia." He gave an example of the anti-cutting rules in the ancient Chinese class: first, he would introduce the general rule of the cut-off, that is, cut the initials + cut the finals and tones = read the words, and then guide the students to spell the specific anti-cut, such as "public" The word is an ancient red cut. At this time, the student will find that the syllables that are cut out from the word + cut words are different from the actual pronunciation of the cut words, because according to the ancient red cut, the pronunciation of the "public" word should be two. "At this time, I wrote down the evolution rule of the ancient and modern tones of 'dividing yin and yang' on the blackboard, and then wrote the anti-cutting regulations related to this law to cut the word (clear sound) + cut the word (flat sound) = cut word (Reading Yinping now.) Gu Feng said that this kind of knowledge involves calculation and deduction. Using a blackboard can better mobilize students to think and remember. "In contrast, if you use PPT, a complicated rule will pass in a few seconds." Students will encounter many problems in the future." In this case, in the classroom teaching, how to balance the relationship between multimedia and blackboard? Or, what kind of classroom teaching is the best? Both must be combined According to Bethan Wing, director of the Center for Higher Education Development Research at Xiamen University, multimedia and blackboards are not a one-of-a-kind relationship, but can be used simultaneously and comprehensively. "As for how to use it, there are several factors to consider." Bethan Wong said that the first thing to look at the content of teaching content, some informative things, or more complex images, audio, video, etc., will be presented with PPT. Effective, and some simple concepts and complex reasoning processes, using the blackboard book will be more intuitive, "also look at a teacher's academic accomplishment, how to understand the teaching content, as well as personal teaching habits, but also consider Students will accept a higher degree of acceptance of which method." For the argument of Bie Dunrong, Gu Feng made further explanations. "If you introduce descriptive and flat knowledge, you can use multimedia means to display it. If it is knowledge about calculation and deduction, then the book is a good choice." Gu Feng said, for example, the teacher of the Life Science Institute talked about the formation of protein. Naturally, we should use animated pictures to broadcast, and when the mathematics teacher speaks about the derivation process of calculus topics, the preferred method is definitely a blackboard. "Let's let the multimedia and keyboard replace the writing is definitely not good, but it is also a dogma to require a certain number of books in each class." Gu Feng said that it is better for teachers to prepare a teaching outline and list the need for demonstration. Audio-visual images and textual knowledge that needs to be copied and deduced, and switch according to actual needs. "But this has higher requirements for teachers and requires more drills before class." In Wang Hua's view, the best way to teach is not just to combine multimedia with blackboard, but also to involve students as much as possible. “Teachers can't sing a one-man show, let students participate. In the whole process of teaching, teachers and students should be integrated and interacted.†Wang Hua said that whether it is multimedia or tablet, the ultimate goal is to provide students with knowledge services. "We should not stick to a specific way. For a course, we should comprehensively consider the three factors of the curriculum, teachers and students to determine how to use multimedia and board books to bring out the advantages and maximum effectiveness of the two.
