PRINCIPALS’ INSTRUCTIONAL LEADERSHIP ROLE AND LESSON STUDY PROGRAM IMPLEMENTATION IN PUBLIC SECONDARY SCHOOLS IN KAJIADO COUNTY, KENYA

The study investigated principals’ instructional leadership role and lesson study program implementation in public secondary schools in Kajiado County. The objectives were to find out the role the principals played in supervising the implementation of the lesson study program and to find out the role the principals played in promoting collaborative practices when implementing the lesson study program. The study was anchored on Carrier’s instructional leadership model and Vygotsky’s social-cultural theory. A mixed-methods research approach was used with a convergent parallel mixed-methods design. The study’s target population consisted of 95 public secondary schools, 95 principals, and 651 mathematics and science teachers from Kajiado County, with a sample size of 29 principals and 248 mathematics and science teachers. This was achieved using probability and non-probability sampling techniques, which included purposeful, proportionate, and simple random sampling. The collection of data was done using an interview guide for principals and a questionnaire for teachers. A pilot study was conducted in two schools that had characteristics similar to those of the schools that were involved in the study. The research instruments were validated by experts with knowledge of instructional leadership from Tangaza University College and the Catholic University of Eastern Africa. The analysis of quantitative data was done using descriptive statistics, which included frequency distributions and percentages, and were generated using Statistical Package for Social Sciences (SPSS) version 25. The data was presented in the form of bar graphs, pie charts, and frequency tables. Qualitative data was analyzed using a thematic approach and presented using narratives and direct quotes. The findings revealed that secondary school principals carried out supervision throughout the process of lesson study by attending lesson study meetings, observing lessons, and giving feedback. They also discuss challenges encountered by teachers during lesson study implementation, such as limited time, lack of funds, heavy workload, and competing programs. School principals were also found to be supportive in terms of collaborations such as teamwork, peer lesson observation, and team teaching. However, the study found some challenges that face such collaborations which include a lack of clear understanding of lesson study by newly employed teachers as well as uncooperative teachers, especially those with many years of experience. The study concluded that despite the challenges facing lesson study implementation, public secondary school principals in Kajiado County make an effort to supervise lesson study implementation. The study also concluded that secondary school principals promote collaborative practices that support the implementation of lesson study programs. The study recommends that Center for Mathematics Science and Technology Education in Africa (CEMASTEA) organizes training on lesson study for mathematics and science teachers with a teaching experience of less than five years as well as sensitization workshops on lesson study for secondary school principals who are newly employed. Also, the study recommends that the Ministry of Education (MOE) develops a clear policy for lesson study implementation. The study suggests that further research be conducted to investigate lesson study program and students’ academic achievement.  Article visualizations:
