许多体育教师都有这样的经验:进行跳高教学时,在同一高度,采用长度不同的横杆,对学生产生的心理影响是很不相同的。使用相对长一些的横杆更有利于消除学生随着横杆的逐渐升高而产生的心理恐惧。这就是利用学生的视错觉服务于体育教学的典型例子。 Many PE teachers have the experience that during the high jump teaching, the psychic impact on students is very different at the same height and using different length of cross bars. The use of a relatively long horizontal bar is more conducive to the elimination of students as the bar gradually increased psychological fear. This is a typical example of using the student’s optical illusion to serve physical education.
