This is a study of values and value systems of various groups of elementary school pupils from ages nine to twelve. The research is based upon Milton Rokeach's (1968) conceptualization of values and value systems and upon his methodology of value measurement. A two-fold purpose of the study is stated: 1) to modify the Rokeach Value Survey in order to make it a more appropriate and reliable instrument for use with 9 to 12 year old pupils and, 2) utilize the modified instrument to investigate differences in the value preferences among subgroups of the population sampled. Several tentative implications for educational practice of the findings of these and related studies and for further research are identified. Seven tables which summarize the measurement instrument and the results of the value survey are included. (Author/SHM)
