Abstract: This study investigated the impact of teachers’ supervisory practices on students’ academic performance in public secondary schools within the Mpwapwa district, Tanzania. Guided by the Servant Leadership Theory and pragmatism research philosophy, the study employed a mixed-methods approach and a cross-sectional research design. The study involved 243 participants, 233 were teachers and 10 heads of schools who were selected using both stratified random and purposive sampling techniques. Quantitative data were collected using structured questionnaires from teachers, while qualitative data were gathered through interviews with heads of schools. Quantitative data were analyzed using descriptive statistics, and multiple regression analysis using Statistical Package for Social Sciences (SPSS version 27), while qualitative data were analyzed thematically to capture insights into instructional supervision practices and their influence on teachers’ instructional quality and students’ learning outcomes. The findings revealed that teachers’ supervisory practices were generally high, with regular classroom observations, timely feedback, performance appraisals, and moderate professional development support contributed positively to students’ academic outcomes. Regression results indicated a strong and statistically significant relationship between teachers’ supervisory practices and academic performance (R = 0.727, R² = 0.528, p < 0.001), suggesting that effective school-based instructional supervision explains over 50% of the variance in students’ learning outcomes. The study concluded that structured and consistent instructional supervisory practices play a critical role in enhancing students’ learning outcomes. Based on these findings, the study recommends that school management prioritize frequent classroom observations, timely feedback, mentorship, and capacity-building initiatives for teachers to sustain and improve students’ academic outcomes.

Abstract: This study examined the influence of instructional support, specifically the provision of teaching materials and instructional supervision, on learner retention in primary schools. Using a mixed-methods design, data were collected from 120 respondents through questionnaires and focus group discussions with teachers, headteachers, and education officers. Quantitative analysis revealed high mean scores for teaching materials (M = 4.12, SD = 0.73), instructional supervision (M = 3.98, SD = 0.81), and learner retention (M = 4.05, SD = 0.76). Correlation results indicated strong positive relationships between provision of teaching materials and learner retention (r = 0.621, p < 0.01), as well as between instructional supervision and learner retention (r = 0.588, p < 0.01). Qualitative findings corroborated these results, with participants highlighting how teaching resources and consistent supervision fostered learner engagement, reduced absenteeism, and improved teacher accountability. The study concludes that robust instructional support systems are crucial for sustaining learner retention, and recommends increased investment in educational resources and regular instructional oversight.

Abstract: This study examined the extent to which instructional supervision contributes to the enhancement of teachers’ professional development in public secondary schools. For the purpose of this study, instructional supervision refers to overseeing instruction as a means to promote teachers’ professional growth and so ensure effective teaching and learning. The study was guided by instructional leadership theory that was developed by Ronald Edmonds in the year 1970. The study, adopted mixed research approach with convergent parallel design. Cronbach Alpha Correlation Coefficient was used to ensure validity and reliability of research instruments. Quantitative data were collected through questionnaires and analyzed using descriptive statistics with the help of Statistical Package for Social Science (SPSS) version 21. Qualitative data were collected through interviews and analyzed thematically. A sample of 92 respondents who included one District Education Officer (DEO), one District Quality Assurance Officer (DQAO), three Ward Education Officers (WEO’s), four heads of schools and eighty-three teachers were involved. Stratified, simple random and purposive sampling was used to select the desired number of respondents. The findings indicate that instructional supervision contributes to enhancing teachers’ ability to use different instructional methods, ability to prepare teaching materials and enhances teaching performance. The study suggests instructional supervisors to continue providing feedback and giving suggestions for improving timely supervision process as intervention strategies to ensure teachers’ professional growth.
