The Application of Modern Educational Technology in Middle School Physical Education Teaching

Name: Zhao Yanqing

Modern educational technology is a modern educational means and method system that applies modern educational theory to education and teaching practice. It includes modern educational media, media teaching methods and teaching design. By comprehensively analyzing the disadvantages exposed by the traditional physical education teaching mode and the advantages of modern educational technology in the information age, this paper systematically expounds the wide application of modern educational technology in middle school physical education, and puts forward operable viewpoints and methods.

Keywords: modern educational technology, multimedia technology, physical education

With the continuous development of computer and information science and technology, new technologies such as multimedia and network are constantly emerging, and the establishment of global information expressway indicates that an information age is quietly coming to us. With the advent of the information age, a new technological revolution, the information revolution, will have a great and far-reaching impact on social politics, economy, education and other aspects. Today, information, energy and materials are called the three major elements of today's society. Whoever grasps the new theory and technology first can create new products with excellent performance and be invincible in the fierce competition. The same is true in sports. Whoever can master the new scientific theories and methods of sports training, the new technologies, tactics and actions of special sports, and develop new and advanced sports training and competition facilities and equipment will dominate the world series and the Olympic Games. It can be seen that the competition of sports is also the competition of science and technology, and the competition of science and technology is the competition of information. However, in today's comprehensive promotion of quality education, the traditional physical education teaching methods are increasingly unfavorable to the all-round development of students. Therefore, how to cultivate students into high-quality talents has become an important research topic for every educator, and physical education, as an important part of quality education, should also be developed in an all-round and balanced way.

First, the disadvantages of traditional physical education:

Teachers' preferences and majors affect the choice of teaching materials.

One of the main tasks of physical education teaching is to make students master certain sports skills, and on this basis, flexibly use and create new sports skills. The formation of a new sports skill is bound to be the process in which teachers explain the technical essentials and demonstration movements in concise language, and the process in which students perceive technology through listening and watching, which are the main sources for students to obtain information. This requires teachers to have high technical level and demonstration ability, otherwise it will directly affect students' learning effect. In addition, a failed demonstration will affect the teacher's image in the eyes of students, so every PE teacher will always arrange more content that he likes and is good at when making teaching plans. Over time, it is bound to violate the principle of all-round development. This phenomenon is common in the traditional physical education teaching mode.

(B) the age of teachers affects the choice of teaching materials

As the saying goes: "Physical education does not provide for the aged", with the growth of age, the ability of physical education teachers to complete actions will definitely decline. When choosing teaching content, they will avoid those actions that are difficult to demonstrate and highly technical, which will ultimately affect the all-round development of students. Some teachers even feel uncomfortable at work and look for other lifestyles. This phenomenon cannot be overcome in the traditional physical education teaching mode.

(C) the difficulty of demonstrating movement techniques affects the teaching process

As we all know, there are many technical movements of flying, high speed and turning in physical education textbooks. It is difficult for students to see these instantaneous movements clearly, and it is also difficult to quickly establish a complete action representation. At this time, the teacher can only demonstrate and explain repeatedly, and the final result will affect the teaching process. And too many explanations and demonstrations can easily make students misunderstand. This is also a difficult problem in the traditional physical education teaching mode.

Second, the role of modern educational technology:

How to effectively solve the disadvantages of traditional physical education in actual teaching has become the key to the reform of physical education. While trying to explore the ways of reform, great changes have taken place in classroom teaching methods. The wide application of modern educational technology has gradually become an effective means to improve the teaching effect. Modern teaching methods are of great significance and role in optimizing physical education classroom teaching, stimulating students' interest in learning physical education, deepening students' understanding of action concepts and physical education theory knowledge, and improving the quality of physical education teaching. Teachers can intuitively and realistically reflect the dynamic change process of technical actions through images, animations, videos, sounds and other media, which can not only attract students' hearing and vision, but also induce students' thinking, thus stimulating students' interest in learning. In the past, teachers spent a lot of time explaining and demonstrating abstract and difficult contents. With modern educational technology, students can make it clear through concrete images. Teachers use modern educational technology to carry out multimedia teaching, so that students' curiosity is stimulated, their attention is attracted by pictures and animations, and students are in a happy state of mind and enter a good learning environment. Therefore, the application of modern educational technology to multimedia teaching will enable students to enjoy learning and take the initiative to learn. At the same time, modern educational technology has promoted the optimization of physical education teaching links such as explanation, demonstration, demonstration, homework, assessment and feedback with its convenient interaction and interest.

Thirdly, the superiority of modern educational technology in the application of physical education teaching;

(A) the application of animation

We can express the teaching content by means of moving, rotating, freezing, slow playing, flashing, color changing and synchronous explanation in multimedia technology, so as to enhance the teaching effect. For example, in the process of explaining and demonstrating technical movements, the movement, rotation and freeze-frame of characters are used to demonstrate the movement trajectory, movement process and spatial position of various parts of the body. However, the traditional teaching methods can not achieve good results by relying on wall charts or teachers' own action demonstrations. Let's take the standing long jump for example. In the process of demonstration, it is impossible for the teacher to explain synchronously and demonstrate in slow motion, let alone rotate and freeze in the air. And it is easier to do it through multimedia technology. Students can intuitively grasp the action points of standing long jump, deepen their understanding, master the correct concept of action and quickly form the action representation through synchronous explanation, movement, rotation, freeze frame and slow release of graphics and animation.

(B) Man-machine dialogue

Multimedia teaching is highly interactive. Teachers can make appropriate courseware according to the needs of the teaching purpose and content of sports theory, and easily realize man-machine dialogue. For example, when the teacher explained the question of "what is offside" in the football rules to the students, he wrote some interactive exercises with multimedia technology. In the exercise, students are asked to choose one of the two picture buttons: the linesman who raises the flag (indicating offside) and the linesman who doesn't raise the flag (indicating no offside). If the answer is correct, a dialog box will pop up with a praise and two buttons of "Explain" and "Next Question". If the answer is wrong, a dialog box will pop up with an encouraging sentence and two buttons of "Explain" and "Next Question". Students can see the teacher's detailed explanation by clicking the "explain" button, so as to check whether they really understand the rules in time. This interactive and entertaining exercise is very effective and it is easy to consolidate the knowledge learned. It can stimulate students' heartfelt interest in learning and fully mobilize their enthusiasm, thus changing passive learning into active learning.

(three) video, audio, pictures and other materials demonstration.

With the help of multimedia technology, teachers can conveniently collect related videos, audio, pictures and other materials scattered in different movies, videos, VCDs and the Internet according to the teaching needs, and then add them to the courseware reasonably and apply them to physical education teaching. Teachers can pause, slow down or play the required audio-visual materials for many times in the process of teaching or students' self-study, or use text descriptions and video images to run synchronously, forming multi-functional and multi-capacity teaching content combining static and dynamic, so as to achieve the purpose of audio-visual combination, vivid and interesting, intuitive image and easy observation and imitation. For example, when teachers teach students the theory of basketball skills and tactics, they let students know the forms and changes of tactical cooperation by playing a large number of CBA or NBA game clips; Through slow play or repeated play, students can clearly see the running route, starting time and technical movements adopted by the midfielder.

(4) Control simulation

By making a controlled simulation demonstration, we can fully express the relationship between some elements in technical movements and sports performance. For example, according to the relevant physical and mathematical formula theorems, the flight trajectory of throwing equipment is simulated, so that students can understand the relationship between air resistance, hand angle, initial hand speed (depending on strength, action distance and action time) and hand height (depending on the height and arm length of the athlete when the hand angle is determined) and sports performance, and draw the conclusion that the faster the initial hand speed, the smaller the air resistance, the higher the hand height and the farther the throwing distance. Under the guidance of the teacher, the suitable angles of each throwing event under different conditions are further discovered.

(5) Comparative analysis

Teachers can compare and analyze students' technical videos or pictures with those of excellent athletes, find out the differences and shortcomings of students' technical movements and help students improve their movements. In the past, this technology was widely used in the training of sports teams, especially for students with poor sense of body and poor sense of movement.

Four, modern educational technology in physical education should pay attention to the problem:

School physical education is different from other disciplines and has its own characteristics and laws. It is a discipline that focuses on students' outdoor physical exercise, supplemented by indoor theoretical teaching, and takes strengthening students' physique, improving students' health level, and cultivating students' moral character, lifelong sports consciousness, interest and ability as the guiding ideology. Therefore, in the application of modern educational technology in physical education, we should pay attention to the following issues:

(1) Multimedia technology is mainly applied to the auxiliary teaching of indoor theoretical courses. When it is applied to outdoor physical education classes, it is necessary to find ways to overcome the difficulties of connecting power supply, mobile computers, monitors and so on, which are not conducive to the whole class watching at the same time. Of course, qualified schools can use laptops to solve the problems of power supply and mobility. You can also use a host computer to connect multiple monitors (computer graphics cards are needed to support multi-monitor connection), and adopt the organization form of group teaching, so that students can practice and watch multimedia courseware in turn in several groups.

(B) the use of multimedia technology in physical education teaching, making multimedia courseware materials must meet the needs of teaching content and teaching tasks. Don't choose some unsuitable materials to deal with just because you can't find suitable materials at the moment, otherwise the teaching effect will be greatly discounted and even have a negative impact. This requires teachers to pay more attention at ordinary times, and to collect, sort out and screen materials extensively and carefully on the basis of understanding the syllabus and thoroughly understanding the teaching materials. The main sources of materials are: (1) obtained from movies, videos, VCD discs or online; (2) selectively intercepting from the existing teaching software as needed; (3) from books, materials, newspapers and magazines; (4) Use some software or cameras, tape recorders and other equipment to make it yourself.

(3) When using multimedia technology in physical education teaching, we should also pay attention to the scientific and educational significance of the content, the practicality and interest of the application of means, and the solidity and interactivity of practice design.

Verb (abbreviation of verb) conclusion:

The combination of modern educational technology and physical education is a new and effective teaching method in the reform of physical education. Although it is rarely used in physical education teaching practice at present, as long as everyone works together in Qi Xin to develop it, its tomorrow will be better!
