众所周知,无论多么优秀的班级,学生的学习成绩总是参差不齐,总有好的、一般的、差的之分。学差生的转化是个广泛关注的问题。学差生的产生,目前看主要有以下三方面的原因:一是因学龄前家教不当导致成绩不好。很多家长都有望子成龙的愿望。孩子刚刚学会说话,就开始教孩子识字、看书。这样,孩子上学后,接触到的都是一些耳熟能详的东西,根本无法唤起有意注意。曾有认知心理学家通过实验展示过这样的现象:假定让一个人看屏幕上投射的字母 E,如果投射时间很短,比如1毫秒,那么这个人就不会看到什么,这说明知觉不是瞬时的;投射时间长一点,比如5毫秒,那么这个人就会看到某种东西,但不知是什么,这说明知觉产生了但辨别尚未产生;如果投射时间长度足以使人看出这个字母不是 O 或 A,但看不出是 E 还是 F 或 K,那么这个人就产生了部分的辨别。由此人们就可以确定完全辨别、部分辨别或刚刚看出有东西所需的
As we all know, no matter how good the class, the student's academic performance is always uneven, there are always good, fair and bad points. The transformation of students is a widespread concern. Students learn to produce the current look mainly in the following three reasons: First, due to pre-school poor tutoring results. Many parents are hopeful hopeful. Children just learned to speak, they began to teach children literacy, reading. In this way, children are exposed to school, some familiar things, simply can not arouse their attention. There have been cognitive psychologists experimentally demonstrating the phenomenon of assuming that a person looks at the projected letter E on the screen and if the projection time is short, such as 1 millisecond, then the person will not see anything, indicating that perception Not instantaneous; a little longer, such as 5 milliseconds, then the person will see something, but I do not know what it means that perception has taken place but the discernment has not occurred; if the length of projection is long enough for the person to see the letter Not O or A, but do not see E or F or K, then this person has produced some of the identification. From there, people can identify what they need to completely discern, partially discern, or have just seen something
