ABSTRACT
This paper examined the difference between principals’ instructional supervisory roles in private and public secondary school in Ogun state. Descriptive research design of the survey type was used for the study. A sample of 100 public secondary schools out of 474, and 100 private secondary schools out of 258 in Ogun state as at February 2017, and 500 teachers out of 15320 teachers in public secondary schools, and 263 teachers out of 4342 in private public secondary schools (including their principals) in the state were drawn using proportionate stratified random sampling for the study. The study developed and used a questionnaire tagged “Principals’ Instructional Supervisory Roles Questionnaire (PISRQ)” with a correlation coefficient (r) of 0.77. The questionnaire solicited responses from the school principals and teachers on their principals’ supervisory roles: instructional development, curriculum development, and staff development. The Pearson Product Moment Correlation Coefficient (r) was employed to analyse the data. While the null hypotheses developed for the study were tested at 0.05 level of significance. The findings revealed that there was significant difference between principals’ instructional supervisory roles in private and public secondary schools; principals’ supervisory styles, principals’ instructional development, principals’ curriculum development, and finally between principals’ staff development in private and public secondary schools in Ogun state. It is therefore recommended among others that the inspectorate division of the state ministry of education should make sure there are uniform supervisory standards to be followed by all secondary schools in the state.
