This study was designed to test four groups of pupils entering the second grade in the York County School Board area--two groups in open schools and two in traditional schools--chosen because of the similarity in the schools' size and location and in the socioeconomic status of the pupils. The students were tested once each year for three years and comparative data were analyzed for 198 subjects who were in the same schools throughout the three years. Results showed no consistent differences in curiosity and creativity between the two types of school systems. However, there was an increasing difference between the students of the two types of schools in their attitude toward schooling. This difference favored the open school system. (Author)
