自引入以来，归一化增益或g因子被广泛用于评估学生在前测试和后测试中的表现。平均g因子可以用班级的平均分数或个别学生的分数来计算。一般来说，这两种计算产生不同的结果。这两个结果的性质在几个理想化的情况下进行了探讨。结果表明，我们也许能够利用两个结果之间的差异来提取有关人口如何因教学而发生变化的信息。(c) 2006年美国物理教师协会。
Since its introduction, the normalized gain or the g-factor has been widely used in assessing students' performance in pre- and post-tests. The average g-factor can be calculated using either the average scores of the class or individual student's scores. In general, these two calculations produce different results. The nature of these two results is explored for several idealized situations. The results suggest that we may be able to utilize the difference between the two results to extract information on how the population may have changed as a result of instruction.
