一般来说,课堂往往存在着积极的和消极的两种因素。积极的课堂因素指与促进课堂教学目的实现相联系的行为,消极的因素是那些明显干扰课堂教学的行为。如喧闹、戏弄同学、扮小丑和藐视、顶撞教师等。影响体育课堂教学的消极因素的产生看上去是学生的问题,也就是授课对象的问题,实际上也与教师有关,不加分析地将课堂里发生的一切问题归咎于学生是不 In general, there are often two positive and negative factors in a classroom. Positive classroom factors refer to activities that promote the achievement of classroom teaching. Negative factors are behaviors that obviously interfere with classroom teaching. Such as noisy, teasing classmates, playing clown and despise, hit the teacher and so on. The negative factors that influence the teaching of PE classroom appear to be the students’ problems, that is, the teaching objects. In fact, they are also related to the teachers. It is not analytical to blame the students for any problems that occur in the classroom
