With the development of science and technology, can network teaching completely replace traditional teaching in the future?

Multimedia-assisted instruction has a great influence on teachers' teaching and students' learning style. Compared with the traditional blackboard teaching mode, the teaching of most subjects has been generally recognized by teachers and students, which is undoubtedly the benefit of the information age. However, everything has two sides. While fully affirming the advantages of multimedia-assisted teaching, we also actively pay attention to some negative effects with a rational attitude. Taking the College of Life Science and Technology of China University of Science and Technology as an example, this paper probes into the functions and significance of multimedia courseware in life science teaching. Through holding multimedia teaching seminars for young teachers and students of all grades, it is found that multimedia teaching has its unique advantages in the teaching of life science courses, but teachers and students also have some similarities in the specific use of multimedia courseware, which deserves attention. In the teaching of life science theory course, multimedia courseware can completely replace traditional teaching AIDS. Under the traditional blackboard teaching mode, biology teaching is always inseparable from traditional auxiliary tools such as wall charts, specimens and models. The teaching of zoology and botany needs not only a large number of morphological and anatomical maps, but also many models and specimens. The teaching of plant physiology and biochemistry also uses a large number of wall charts to describe metabolic pathways. In many cases, especially the classroom teaching mode of human anatomy lacks intuition, and teachers often use animal and plant specimens or models, wall charts and so on. Therefore, in the traditional teaching of biological theory, traditional teaching tools, such as wall charts, specimens and models, have played a very important role. With the emergence of computer and network technology, multimedia courseware assisted teaching, including sound, color, animation, video, photos and pictures, proves the knowledge world of three-dimensional space+color+animation. Entering the classroom will enrich the perceptual knowledge of classroom teaching, not limited by time and space, greatly improve the efficiency and teaching quality, and improve the level and means of talent training. Multimedia courseware has incomparable advantages over traditional teaching AIDS, such as a lot of information, graphics, audio and video, intuitive dynamic effects, and a wide range of teaching materials (video, scanning, photos, drawings, etc.). ); Teachers can easily prepare lessons and copy them. It is very convenient to modify and update their knowledge. Students can copy and print courseware or review online. Multimedia courseware has unique advantages in learning life science and studying biological morphology, structure, anatomy, classification, growth, development, movement and evolution. Therefore, the use of multimedia courseware in life science courses is welcomed and recognized by more and more teachers and students. Multimedia courseware, College of Life Sciences, almost all professional courses and professional basic courses are equipped with multimedia teaching system in all classrooms, and a website for downloading courseware and reading has been specially opened on the college website, which has become an important part of teaching activities. Second, the content and nature, the choice of life science courses and the requirements of multimedia courseware. There are still some differences in the content and nature of courses in the field of life science. Some courses are descriptive, morphological, structural and classified, except descriptive content, mathematical formula derivation and calculation, while some courses completely describe the main structural changes in the process of metabolic dynamics. Therefore, many courses require us to adopt flexible and diverse teaching methods according to the nature and characteristics of the course. The structural characteristics of animal and plant morphological description are mainly demonstration and grouping, such as using multimedia courseware in the teaching process. Wonderful photos of animals and plants, as well as the fine structure of photos under microscope and electron microscope, can make classroom teaching come alive. The courses of ecology, microbiology and genetics, their contents, their morphological description, mathematical analysis and introduction of metabolic mechanism. Therefore, in the teaching process of these courses, most of the content should be the use of multimedia courseware, while the other part of blackboard and chalk teaching will be better. For example, for the population ecology type of population growth, you should use the blackboard to gradually draw the population index growth model and Logistic growth origin equation. If the content of these parts is still taught by multimedia courseware, it is certainly possible, but students will accept that they prefer simple deductive teaching on the blackboard. In all courses in the field of life science, the theory is that multimedia courseware can be used to assist teaching. However, according to the teaching content, reflecting students and teaching practice, it is generally not suitable to use multimedia teaching to derive mathematical formulas, chemical molecular structures or chemical reaction equations in the teaching content, and should be written on the blackboard temporarily.
