Since sports knowledge is no exception, in order to enable students to learn more basic knowledge, develop students' intelligence and cultivate students' teaching ability in a limited time, point-based teaching is adopted to cultivate and develop students' thinking ability, stimulate students' interest, mobilize students' enthusiasm for learning, give full play to teachers' leading role and students' main role, and achieve the best teaching effect. Making full use of modern educational technology in physical education teaching can highlight the teaching focus and break through the teaching difficulties. Through computer-aided teaching demonstration, the instantaneous actions that are difficult to stop are clearly reflected in front of students, so that students can get deep feelings, stimulate their interest in learning and concentrate, which is also conducive to creating a relaxed learning atmosphere, giving students a broad thinking space and cultivating their rich imagination and innovative consciousness.
First, create situations to stimulate students' interest in learning, create a democratic atmosphere and cultivate innovative consciousness.
Psychology tells us that interest is a positive tendency to objective things and a complex personality quality, which can promote people to explore new knowledge and develop new abilities. But interest is not innate, it is initiated and developed under the influence of certain education. Pupils are curious and have no intention of paying attention. Any new appearance can arouse students' strong interest. The application of audio-visual media will make teaching more intuitive and vivid. It can turn static into dynamic, abstract into concrete and abstruse into simple. It can effectively focus students' interest and attention on classroom teaching activities, and make students love and enjoy learning. For example, if traditional demonstration and explanation methods are used to teach students the technical action of forward roll, the effect is not ideal. Because in class, the teacher will demonstrate the complete action first, and then explain and analyze it. Everything is abstract, which can't give students an intuitive feeling visually, and it is not easy for students to understand. Students' attention is easily distracted and it is difficult to fully grasp it. However, if multimedia-assisted teaching is adopted in the classroom, the whole technical movement of forward roll will be displayed on the screen with the help of teaching software, and the demonstration movements and graphic decomposition recorded in advance by the teacher will be displayed, as well as the text explanation of squat-holding the mat with both hands, bending the arm, lowering the head-kicking the ground twice-lifting the buttocks and abdomen-moving the center of gravity forward to roll the ball-the occipital bone, shoulders and buttocks touch the mat in turn-holding the calf ball into a squat. According to the needs of the class, the pictures are repeatedly played and explained, and the teacher demonstrates them in class. In this way, students can form clear and complete technical movements in their brains, be more energetic and active when practicing, understand the essentials of movements more intuitively and master technical movements faster. This is also in line with children's psychological characteristics of easier understanding and strong sense of identity for intuitive, interesting and novel things. For another example, multimedia teaching also plays a great role in pointing out the wrong actions that are easy to occur and correcting methods. Then we can use pictures to demonstrate all kinds of wrong actions. Students can think by looking at the pictures carefully. Then, the teacher carefully analyzes and explains the root cause of the wrong action, and then corrects it. In addition, you can also clip some excellent athletes' competition videos into teaching software and show them to students in class, so that students can have a preliminary understanding of the application of somersault in sports, thus stimulating their interest in learning, so that if you continue to practice forward tumbling outdoors in the future, you will get twice the result with half the effort.
Second, use audio-visual media to break through the difficulties of teaching materials and cultivate students' innovative thinking.
For example, in the teaching of throwing, there is a wealth of physical knowledge. With the help of computer animation simulation demonstration, students can clearly understand that the throwing distance is influenced by air resistance, throwing angle, throwing speed, throwing height and other factors, and some of these factors can not be changed objectively. Controlling throwing angle and throwing speed is the best way to improve sports performance. Then, through the video of athletes' actual combat, through slow play, freeze frame and animation demonstration of their shooting angles, students can understand the shooting angles of different throwing events under different conditions and apply them in practice, which not only breaks through some difficult problems in throwing teaching, but also effectively stimulates students' interest in exploring the principles of sports science and promotes the integration of physical education teaching and subject courses. For another example, when students learn "standing long jump" in senior grades, it is difficult to observe and imitate it only by a few instantaneous demonstrations in the classroom of physical education teachers. If VCD and video camera are used to slow down the action of elite athletes' competition practice, students can spend enough time observing and imitating this action. Then play or replay the four main points of run-up, jump, air slide, abdomen expansion and chest expansion, and buffer landing respectively. At the same time, the teacher combined with pictures, properly analyzed and told, thus highlighting the focus of the abdomen and chest in the air, breaking through the difficulties of run-up and stride, and solving the existing problems. Third, reform the physical education teaching mode and cultivate students' innovative spirit.
The intuition of audiovisual means can attract students' attention in teaching. If teachers flexibly use audio-visual means according to the teaching content and give full play to the interest of audio-visual means, students can acquire knowledge in intuitive images and interesting activities, have a strong interest in what they have learned, stimulate curiosity, maintain a high degree of learning enthusiasm, and then guide students to carry out innovative and creative thinking. Therefore, in teaching, I strive to enhance the interest of audio-visual education as an important means to stimulate students' interest in learning, stimulate their desire for knowledge and cultivate their creativity.
In the design and implementation of "Squat Start", at the beginning of class, listening to music and taking photos for queue practice can not only stimulate students' interest in physical fitness, but also improve their queue level of "March in a hurry" and let them be influenced by beauty. Warm-up exercise: I let students imitate various animals in nature to jump, let students manipulate the mouse, and get a lot of information in CAI courseware. I have collected a lot of dynamic shots of various animals in nature in my CAI courseware. Students are interested in independent imitation in the symphony of nature, cheetah run, zebra run and deer run, and naturally innovate to prepare for exercise. In teaching, I use CAI courseware to design animation. Why does Xiaoming run faster than Xiaoguang? Vivid questions have effectively inspired students' wisdom, and students are discussing with great interest and scrambling to express their opinions. The multimedia computer effectively helps students to move from the initial learning of "standing start" and "squatting start" to the further learning of "squatting start".
The values of new basic education hold that: "Basic education serves social development and students' lifelong development. Schools should take the development of each student's potential, healthy personality development, self-education, and the initial formation of lifelong learning consciousness and ability as the most fundamental tasks? "In the practical exploration of optimizing physical education classroom teaching and implementing quality education with the help of audio-visual media, the core of this course is to respect students' needs, attach importance to students' emotional experience and promote their all-round development. From design to evaluation, this course is always centered on students' active and all-round development. While paying attention to the leading role of teachers in teaching activities, students' main position in learning is particularly emphasized, so as to give full play to students' learning enthusiasm and learning potential in squatting and improve their physical education learning ability. At the same time, pay attention to individual differences and different needs to ensure that every student benefits. This lesson pays full attention to students' individual differences in physical conditions, hobbies and sports skills. At the beginning of squatting, students are allowed to use CAI courseware to assist learning according to their actual freedom or in pairs. Finally, let the students recommend their own team leaders according to their own reality, form groups freely and flexibly, and use CAI courseware (the material of excellent long jumpers) to choose the best way to learn squat start? For students
Leave a broad choice and development space, so as to ensure that the vast majority of students can complete the learning objectives of this course, and through independent cooperative learning, every student can experience the fun and success of "squatting" learning and meet the needs of self-development.
4. Integrate traditional mathematics teaching methods.
Psychology tells us that perception directly affects the quality of representation. The more direct and concrete the perceptual materials are, the more senses students mobilize, the more vivid and intense the perceptual image, and the clearer, deeper, more stable and lasting the representation. The representation that can best reflect the real image is the physical representation, which is the best intuitive teaching aid. Students can perceive the shape, size, color and position of objects through vision, and can perceive the softness, hardness, cold, heat, light and weight of objects through touch and pressure. Therefore, the physical demonstration has a strong sense of reality and three-dimensionality, which cannot be completely replaced by audio-visual demonstration. Of course, due to the limitation of conditions (such as low visibility), physical demonstration often affects the perceived effect and the dynamic activities of representation. Therefore, in teaching practice, if we can organically combine audio-visual teaching method with action demonstration, we can give full play to their respective advantages and achieve better teaching results. In the lesson of "Jumping Goat", we creatively combine objects and projections to teach, and achieved good results. In order to let students know some characteristics of jumping over a goat, the action is separated from the physical projector and the focal length is adjusted, so that the key points and difficulties when jumping over a goat are clearly reflected on the screen. For the first time, the students clearly saw the relaxed posture of the goat, which was extremely novel and focused, leaving a clear reality in their minds. In addition, the use of audio-visual teaching equipment brings convenience and quickness to the form conversion and connection of teaching carriers, which enables teachers to display more teaching information in a short time, greatly improves the capacity of classroom teaching, and enhances the learning speed and acquisition efficiency of students.
Practice has proved that the clever use of information technology and the introduction of slides, videos, projections and other means into physical education not only greatly stimulated students' enthusiasm for learning and trying, but also made them edified by beauty, enabling them to increase their ability to feel, express and create beauty in a beautiful situation. Modern teaching methods and traditional methods were organically combined, supplemented and comprehensively applied, thus making physical education teaching reach a new level in form, content and teaching effect.
