Abstract

• The general objective of this study is to study factors affecting principals’ instructional supervision practices in Basic Education High Schools in Pathein and Thapaung Townships. In this study, sample size of respondents such as thirty-six principals and 216 teachers from Basic Education High Schools were selected by using purposive sampling for principals and equal-size sampling for teachers. The questionnaires and open-ended questions were developed and modified the items by reviewing on Wanjiru’s (2015) items, theorical framework and previous related literature to collect the required data. Four-point and five-point Likert-scales were employed to identify the level and extent of principals’ instructional supervision practices (Coklar et al., 2016). The internal consistencies (Cronbach’s alpha) were 0.87 for principals and 0.96 for teachers. Descriptive statistics, One-way ANOVA, Independent Samples t-Test and Multiple Regression were used to analyze the quantitative data. Principals’ instructional supervision practices practiced in this study was high (Mean=3.36, SD=.37). There were no significant differences in practices of principal instructional supervision between the groups of gender and administrative experience. There were significant differences in principals’ instructional supervision practices between the groups by age, position and school size. According to the results of multiple regression analysis, position, work load and teachers’ attitude are the best predictors of factors on principals’ instructional supervision practices. As the results of qualitative study, open-ended responses of principals and teachers were consistent with the findings of quantitative study.
