本文通过对所罗门三控制组实验法的研究 ,发现该实验法的两个缺陷 :一是 ,所有四组(实验组和三个控制组 )的前测和后测都同时进行 ,但是第二控制组 (R3)和第三控制组(R4 )由于没有前测 ,无法了解后测的意义 ,因此 ,取R1和R2 中的前测平均数代之。这样的表示只能是“近似地表示” ,存在水分。二是 ,该实验法没有把实验刺激所带来的影响考虑进去。所以 ,实验结果不能保证真实性 ,进而构想出了一种自然化的单控制组实验法。
In this paper, we study the experiment of Solomon III control group and discover two defects of this method. One is that the pre-test and the post-test of all four groups (experimental group and three control groups) are carried out at the same time, but the second control The group R3 and the third control group R4 can not understand the meaning of the post-test because there is no previous test. Therefore, take the pre-test average in R1 and R2 instead. Such a representation can only be “approximately”, there is moisture. Second, the experimental method does not take into account the impact of experimental stimuli. Therefore, the experimental results can not guarantee the authenticity, and then conceived of a natural single-control-group experiment.
