五、学生数学能力的总体分析(一) 用因子得分刻画学生的数学能力目前评价学生的知识或能力,大多采用综合的方法,如原始分简单累加,或各个分值的加权平均,其结果可用一个数据表示总体情况。这种方法确有不少优点,至今仍被人们广泛地使用。但是我们不能满足于把学生的知识能力计成某一数量,而应该进一步指出能力因素的构成状态。研究的方法除了综合之外,还有分析的方法,因析法提供了各个层级上的因子得分这一评价能力的新思路。根据前文分析,青浦县学生学习数学的能力水
V. General Analysis of Students’ Mathematical Abilities (I) Describing Students’ Mathematical Ability with Factor Scores At present, students’ knowledge or ability are mostly evaluated by comprehensive methods such as simple summation of original scores or weighted average of scores, and the results are available A data shows the overall situation. This method does have many advantages and is still widely used by people today. However, we can not be satisfied with counting the students’ knowledge ability as a certain amount, but we should further point out the constitutional status of the factors of ability. In addition to the research methods, there are methods of analysis, which provides a new idea of the evaluation ability of factor scores at all levels. According to the preceding analysis, Qingpu County students learn the ability of water
