Prefatory Note 



This Study contains five separate investigations in the learning 

 of arithmetic in Indiana schools. In each instance the Courtis 

 standard tests were used to measure the efficiency of the children 

 whose work was tested. The first two investigations are con- 

 cerned with the measurement of the actual efficiency of the schools 

 in question near the close of the second semester, 1915. The 

 material for these studies was gathered for the most part thru 

 the Indiana University Bureau of Cooperative Research. For 

 the purposes of this report this material is divided into two parts, 

 one dealing with the city schools, the other with the rural schools. 

 The first, covering 22 city systems, is reported by Mr. M. E. 

 -Haggerty. Mr. Paul Mort is responsible for the report on the 

 rural schools of five counties. 



In addition to these measurement results there are three in- 

 vestigations on the effects of drill in arithmetic, as follows: 



(a) An investigation of the effects of six weeks' daily drill in 

 addition, by Mary A. Kerr, principal of the Department school, 

 Bloomington, Ind. 



(fe) An experimental investigation of the effects of drill in 

 arithmetical processes under varying conditions, by Herman 

 Wimmer, superintendent of schools in Rochelle, 111. 



(c) An experiment with Courtis Practice Pads, b}^ Flora 

 Wilbur, principal of Fort Wayne training school. 



Acknowledgement is due to the numerous school superin- 

 tendents, principals, and teachers for their services in giving tests 

 and doing the initial work in scoring the results. No less credit 

 is due the University authorities for their cooperation, to 

 President William L. Bryan and the Board of Trustees for the 

 funds with which the work of re-scoring and tabulation was 

 carried on, to the graduate students and assistants who assisted 

 in the work, and to the ever-patient Office of University Publica- 

 tions in whose hands a somewhat chaotic manuscript has taken 

 final shape.
