一、直观动作示范的需要案例:水平三肩肘倒立同题异构课,一位教师主要通过挂图来讲动作方法,动作缺欠完整性和连续性;另一位教师主要以边示范边讲解、巡回指导示范和正误示范等方法进行示范教学,期间还引来学生数次自发的掌声。笔者观察发现后者的课,学生技能掌握情况要明显好于前者。分析:时下很多体育教师在讲解示范时过多依赖挂图或视频等媒介,造成这一现象主要有两方面原因:一是主观上认为这些媒介可以代替教师本身的动作示范;二是担心技能和体能退化,怕在学生面前 First, the need for an intuitive demonstration of action cases: the level of three shoulder elbow inverted the same problem with different courses, a teacher mainly through the flip chart, the action method, the lack of completeness and continuity of action; another teacher mainly to explain the edge of the demonstration tour Guiding demonstration and demonstration of positive and false demonstration and other methods of teaching, during which also attracted several spontaneous applause from students. The author observed that the latter class, master the skills of students should be significantly better than the former. Analysis: Many PE teachers nowadays rely too much on charts, videos and other media to explain the demonstration. There are mainly two reasons for this phenomenon: one is that these media can subjectively substitute the teacher’s own demonstration of action; the other is worry about skills and physical ability Degradation, fear in front of students
