Normal Growth without Drill during Six Weeks. — Table V 

 shows the results in grades 7 and 8 where during the first six weeks 

 there was no drill. These pupils generally did not know that they 

 were to be given a second and third series of tests and so were 

 not preparing to make better grades. The table shows that the 

 average of the two gains made by these grades on the whole 

 series of eight kinds of problems was 16.233 per cent. In funda- 

 mentals both grades made approximately the same gain, but in 

 reasoning grade 8 far surpassed the grade 7. The average for 

 both grades in reasoning, taking into consideration correct 

 answers only, was 35.36 per cent. 



The normal growth for the six weeks is probably not nearly 

 so large as the figures would indicate. The reason why the pupils 

 were able to increase their grades so much was that at the second 

 series of tests they knew just what kind of work to expect in each
