What opportunities and challenges does technology present to the teaching profession? How should modern science and technology be utilized for professional development?

Abstract: With the progress of science and technology, the level and means of education are constantly improving. Modern information technology with its distinctive features applied to physical education teaching, will certainly strongly promote the reform of the teaching content system, promote the innovation of teaching methods, change the existing teaching mode. How to realize the effective combination of modern information technology and physical education teaching is an opportunity and a challenge for physical education teachers. In order to better adapt to modern physical education teaching, how can physical education teachers face the opportunities and challenges brought by modern information technology to themselves?

Keywords: information technology; physical education teachers; opportunities; challenges

Opportunities are often accompanied by great challenges. The use of modern information technology in physical education is an opportunity for physical education teachers, but also a responsibility and a challenge to test the teaching combat ability of each of our physical education teachers. Therefore, we can not ignore the opportunities and challenges brought to us by the arrival of the network era.

1 Opportunities brought by modern information technology to physical education teachers

1.1 The network has penetrated into the field of sports.

Today almost in all schools have a network platform, the network of comprehensive websites have sports channels, in the final analysis, sports networking will be the distinctive sign of sports modernization, it can be foreseen that in the future of sports, from physical education, sports training and competition to sports culture, are inseparable from the network. Whether it is the teaching of sports theory classes or sports technology classes, the position of modern information technology in sports teaching will become more and more important. "Iron first must be hard", as a front-line physical education teachers, but also to keep pace with the times, give full play to the advantages of modern information technology teaching, face up to the value of the use of traditional means of teaching, can be reasonable and correct use of modern information technology, so as to truly enter the modern era of teaching.

1.2 Modern information technology to physical education teachers.

1.2.1 "Sound" to the physical education teacher's help

The earliest use of multimedia for teaching in school is the physical education class. It was the teaching of "Radio Gymnastics". "Radio gymnastics" and the current physical education class to play music to do some of the activities of teaching, is to use multimedia teaching in the "sound" for teaching, only the primary stage of multimedia teaching, is not the true meaning of multimedia teaching. Sound is the soul of the action, sometimes soothing, sometimes strong rhythmic music, for the injection of new vitality, which not only eliminates the boring monotonous physical education teachers command, but also make the exercise in the enjoyment of beauty.

1.2.2 camera, play like, slide, projection, etc. on the help of physical education teachers

Camera, play like, slide, projection means to our physical education has brought a lot of intuitive teaching, can effectively improve the quality of teaching. The use of cameras, video, slides, projection and other means of teaching, fundamentally solve the human demonstration of the action of a passing, students do not have a deep impression of the drawbacks, but also solved the problem of the wrong action of the law can not be said to do so, so that the students of the positive and wrong action of the impression is very clear, so that students in the practice of targeted. At the same time can be explained and demonstration, dynamic and static, decomposition and complete action organic combination, not only can improve the correctness of the demonstration action, but also improve the integrity and continuity of the action, so that the students in the brain to establish a correct and complete action. At the same time, the close combination of watching, thinking and practicing can also improve the students' observation and thinking ability, mobilize the enthusiasm of learning, improve the interest and efficiency of learning, so that the students can understand the main points of the movement faster, better establish the correct movement appearance, and promote the formation of motor skills.1.2.3 The help of video recordings for physical education teachers

Video recordings in physical education make the standardized movement More image, intuitive, easy for students to imitate, we know that perception is the result of coordinated activities of multiple analyzers, which requires us to mobilize their various analyzers to participate in the activity. In specific teaching, no matter how skillful the teacher's demonstration, to make the students to achieve accurate judgment and the formation of complex action appearance, it is somewhat difficult, because the complex demonstration, often completed in an instant, in this instant, if the students do not have the ability to focus on observing the demonstration of the action, it is not possible to form a complex action appearance, and the use of multimedia teaching can be used to play fast and slow, freeze frame, zoom and other means, the inconvenience of breaking down the technique. The use of multimedia teaching can use fast play, slow play, freeze frame, zoom and other means, the inconvenient decomposition of technical action into several details, highlighting the key points of the action, the difficulty, so that the students to establish a correct action image, improve their ability to analyze and solve problems, and better complete the teaching task.

The application of students' own action video. The main purpose of the students' own action video is to feedback the effect of classroom practice, to correct the teaching deviation, to strengthen the improvement, to master the technique, and to reduce the error rate. When a period of teaching should be carried out after the students' action technology and tactical use of video in the game, so that teachers and students can clearly understand each person's learning situation, to find the formation of technical and tactical development of the shortcomings, correct errors, the formation of the correct technical and tactical, so that teachers and students can take the problem into the classroom. In the learning process, students more consciously do what the teacher asks, so that they can well complete the teaching task and improve the effect of sports teaching.

2 Opportunities and Challenges for Physical Education Teachers Brought by Modern Information Technology

2.1 Physical Education Teachers Should Recognize the Situation and Have a Crisis Awareness

Every one of our physical education teachers should have a clear understanding that, in today's highly developed information society, the mastery and use of modern technology for teaching is not only a requirement for the teachers' basic qualities, but also a requirement for the students' basic abilities and basic knowledge, which undoubtedly puts forward new requirements and conceptualization of the teaching content and target structure of traditional physical education. The knowledge of modern technology and the mastery of operational skills has become an important component of the quality structure of future talents.

2.2 Physical education teachers should "charge" in time to learn and adapt to modern sports teaching

Physical education teachers should grasp the wave of modern information technology brought to us, "charge" in time to follow the trend. Physical education teachers to enhance the ability to better improve the quality of physical education teaching, the information age requires physical education teachers to fully learn information technology and very high use and physical education teaching, which requires physical education teachers to learn and be able to master modern information technology. For a physical education teacher is not only required to have profound professional knowledge of physical education, practical ability and rich teaching level, but also requires teachers to have the concept of modern education, computer multimedia teaching knowledge and the ability to master the use of modern education and teaching methods and methods, and constantly developing and updating their own knowledge, enrich themselves with knowledge, in order to be able to meet the mission entrusted by the times, in order to be able to meet the needs of modern physical education teaching. Only by continuously developing and updating our knowledge can we fulfill the mission entrusted to us by the times and the needs of modern physical education. May we physical education teachers seize the opportunity, challenge ourselves, challenge the future, and create a new situation of physical education teaching
