学生的学习分化是影响教学质量以及提高合格率的关键。为了解“分化”的时间,各主课的分化程度、学生的智力与分化的关系等等,我校教育科研小组进行了一年多的跟踪调查和二年多试验。首先对当时的初一年级四个班进行了团体智力测定,并与一所普通完中同年级的一个班级对照。基本情况说明(我校学生入学成绩的最高分是对照班所在学校的最低分)学生在智商上与对照班相差一个等级。我校各班和年级的平均智商均为中下,对照班为中等。我们又将采集到的数据(智商分数)和入 Students’ learning differentiation is the key to influencing teaching quality and improving the passing rate. To understand the “differentiation” of the time, the degree of differentiation of the main course, the relationship between the intelligence and differentiation of students, etc., our school education research team conducted more than a year of follow-up surveys and more than two years of experiments. First of all, there were four groups of first grade at the time of the group mental determination, and with an ordinary finished in the same grade a class control. Description of basic information (The highest score of students in our school is the lowest score of the school where the control class is located.) Students differ by one level from the control class in IQ. The average IQ of each class and grade in our school are middle and lower, and the control class is medium. In turn we will collect the data (IQ score) and into
