Recently, I sent a photo of a university professor's classroom teaching on the official website of the Massachusetts Institute of Technology (MIT) and a photo of a young teacher's classroom teaching at Huazhong University of Science and Technology through WeChat.Both classroom photos show the teaching style of blackboard books.I once wrote "College Classroom Teaching Board Books and Multimedia, October 22, 2013 Science Network" to talk about my understanding of the use of board books and PPT (multimedia) in college classroom teaching.Among them, there are two math teachers in the class, one completely adopts board writing and one completely adopts PPT.As an "old student" I still feel the style of classroom teaching with the use of calligraphy teachers, and give my excellent evaluation (the teaching content organization and oral expression are also good).This time, WeChat university teachers sent a unanimous voice of praise for the classroom teaching board in the photo, so that the board book returned to classroom teaching is everyone's familiarity.
A young teacher at Sun Yat-sen University said: "Praise the teacher, in fact, the university teacher should have done so in class.A young teacher who has just graduated from a doctoral degree to teach at a university: this is too strong, now most of the domestic students are reading according to PPT, the whole board is too difficult, teaching or to return to the source.A professor at Wuhan University and another young teacher at a key university in Wuhan offered to take a chance to see the young teacher's classroom teaching in person.A young professor at Kunming University of Technology said: "The professor's basic skills are too solid, and so many formulas have been deduced in detail."A professor at Southeast University: Huazhong University of Science and Technology has a good tradition, and there are few good teachers who write completely.A teacher who knows something about the young teacher's experience: it is indeed the happiness of students who have been cultivated in Europe and the United States for a long time.Another young teacher said: Board writing can really improve students' attention, but also can lead students' ideas, interlocking, a little carelessness will fall behind, so indirectly forced them to follow the teacher's board.PPT can walk the horse to see flowers, but also can also N cycles, so students are not so strong in thinking.A senior at Zhengzhou University: This is a good teacher, I feel like I am taking a math class, and math board books are more acceptable than PPT.A postdoctoral fellow at Macao University of Science and Technology: awesome!It feels like very few teachers are now able to completely board.From the perspective of students attending lectures, the board book is more impressive than the PPT, said a Ph.D. graduating student.
In fact, whether college classroom teaching uses board books and PPT is by no means just a formal difference, but a difference in classroom teaching concepts.In my classroom teaching experience, in addition to curriculum teaching content organization and oral expression, I always think that classroom teaching board book is the most basic form of teaching content.A supervisor (retired professor) at a major university recently went to listen to the classroom teaching of a young teacher, who learned from relevant sources that young teachers fully use board-based teaching and received praise from students.The young teacher communicated with the supervisor in a timely manner to hear his opinions on classroom teaching.The supervisor was satisfied with his classroom teaching.The keynote speaker has studied and worked at many universities overseas for many years, and has never used PPT in foreign universities or in class.
However, the young teacher found that even for his classroom board teaching students are not very fond of taking notes, students often use mobile phones to shoot board books, and perhaps after class students will use photo-sharing board to master the course.I analyze the main reasons why college students don't like to take notes in class, in addition to the fact that they can now shoot board books with their mobile phones, it may be related to some of the keynote teachers mainly rely on PPT teaching.Some teachers' PPT content is detailed, the production is very beautiful, the visual effect is good, maybe after class teachers will send PPT to students to "share".Some teachers test content is closely related to PPT content, and finally both teachers and students are happy, of course, students really grasp the course knowledge only students themselves know.However, it is said that the young teacher who insists on using board to teach the curriculum has about five students every time, but the strict requirements are the style of the young teacher's undergraduate teaching.
It is not only a form of classroom teaching, but also a profound connotation, especially for science and engineering majors who have a lot of mathematical physics formula derivation process.In addition, teachers will often pause oral explanation in the course, which is conducive to students' timely understanding of the curriculum key knowledge impression, so as to improve the quality of curriculum teaching.Many years ago, an old teacher told me that for genetic reasons he speaks faster in class, so he increased the volume of books to control the speed of speech, so that students have time to digest certain difficult concepts.A student living in the U.S. remembers my blackboard math-physics formulas on the phone when I was in class (the geophysics major used a lot of modern math-physics knowledge) and used wall charts drawn by school drawing room drafters.However, some teachers now use PPT to teach with a laser pen one by one, such a teaching method is difficult to control the pace of classroom teaching, affecting the quality and effectiveness of teaching.In addition, the instruction of classroom board book is also conducive to improving class efficiency, because the student's classroom notes is a hand-brain process, which is conducive to students' in-depth understanding of the course content.Someone told me that a senior professor at MIT Computer Science and Artificial Intelligence Laboratory (CSAIL) in the United States mentioned that in addition to the content organization, it is necessary to design the layout of classroom boards.This shows that world-renowned university teachers attach importance to the concept of writing in the classroom teaching, which is worth learning from.
In short, we hope that our university teachers will pay attention to the board books in undergraduate teaching and show your learning style in classroom teaching, so that our students will not only learn knowledge in classroom teaching.
