体育课是一个开放性的课堂,同学们的视野开阔了,活动空间更大了,再加上小学生天性活泼好动,一有风吹草动就会丧失全部的警戒阵地,随着新奇事物的出现而转移了注意力。从心理学上讲,这种情况是低年级的小学生无意注意起很大作用,他们兴奋抑制的产生比较迅速,第二信号系统的抑制作用较弱,容易受外界新鲜、突变和运动的事物所吸引,从而容易分散注意力。随着教师向学生提出各种要求,特别是学习任务的增多,学习活动仅靠无意注意是无法完成的, Physical education class is an open class, students have a broader vision, activities more space, coupled with the pupils nature is lively and motivated, as soon as signs and weaknesses will lose all alert positions, with the emergence of novelty and the transfer Attention. In psychology, this situation is that primary school pupils of lower grades have a great role to play in their inadvertent attention. Their excitement and inhibition are relatively rapid. The second signal system has a weak inhibitory effect and is susceptible to external freshness, mutation and exercise. Attract, easily distracting. As teachers make various demands to students, especially the increase of learning tasks, learning activities can not be completed by unintentional attention.
