一、体育课练习密度的认识与思考体育课的练习密度是指一节课中学生实际从事练习的时间与上课总时间的比例,它是衡量教学质量的一个重要方面。体育课的练习密度到目前为止还没有一个统一标准,主要是因为其受教材、课的类型(新授课,复习课)、学生的体能技能储备、课堂教学纪律、教师驾驭课堂的能力等因素的影响而难以统一。当然,练习密度过低,肯定说明课的设计有问题。金钦昌老师编写的《学校体育学》一书中认为比较合理的体育课练习密度在30%~50%之间;美国的SPARK课程在评价体系 First, the practice of physical education practice knowledge density and practice Physical education practice density refers to a class of students actually engaged in the practice of time and the proportion of total time, it is an important aspect of measuring the quality of teaching. The practicing density of PE class has not yet reached a unified standard so far, mainly because of its teaching materials, the types of classes (new lectures and refresher courses), the students’ reserve of physical skills, the discipline of classroom teaching and the ability of teachers to control the classroom Impact and difficult to unify. Of course, practicing density is too low, which certainly indicates that there is a problem with the class design. Jin Qinchang teacher’s “School Physical Education” a book that is more reasonable physical education practice density of 30% to 50%; the United States SPARK curriculum in the evaluation system
