In this particular study the problem is to find which types of books pupils of the fifth grade of different abilities and of different socio-economic status like to read. This study is also concerned with the comparison of boys and girls in their choice of books and magazines.

In this particular study the problem is to determine the influence working after school hours has upon a group of junior high school boys. This study is concerned with comparisons in subject matter achievement, self and social adjustment, and behavior records and ratings. It is the purpose of this study to make these comparisons with boys who work after school and those who do not.

The three-fold purpose of this study is: 1. To contrast the physical, mental, and emotional development of children who were six to six and one-half years old with those who were older than six and one-half at the beginning of the school year. 2. To contrast the amount of progress made in subject-matter achievement and in emotional development. 3. To determine, by comparison of the two groups, which group had the advantage as far as subject-matter achievement, adjustment, and behavior were concerned.
