Abstract
The purpose of this study was to improve a so called wasted junior high school through methods of group dynamics over a 3 year period. The main results are as follows; 1) Frequency of anti-social, delinquent behavior, and acts of violence toward teachers decreased to one-ninth of what they were 3 years previous (decreasing in number from 78 to 9). 2) The average scores of achievement tests, in which full marks were 200, increased by 30 points. 3) Of all the atheletic clubs, nine of them won championships, which used to be four.
