由于体育教学的局限性,长期以来,教师怕麻烦,总是带着一个哨子一张嘴来进行授课,严重地影响了学生的运动兴趣和学习动作技术的规范性。在体育教学中运用电化教学手段激发学生兴趣,规范练习动作,提高运动技能,助推体育教学,正是现代体育教师迫切研究的课题。 Due to the limitations of physical education, teachers have long been troubled by troubles and always taught with a single whistle. This has seriously affected students’ interest in sports and standardized learning of motor skills. In the PE teaching, using the galvanized teaching method to arouse the interest of students, standardize the practice actions, improve the sports skills and boost the PE teaching are exactly the topics that the modern PE teachers urgently study.
