Key Barriers to the Implementation of Competency-Based Education Towards Life Skills and Character Formation in Catholic-Sponsored Public Primary Schools in Ngong, Kajiado North Sub-County, Kenya

This study explored collaborative lesson planning practices as part of lesson study-based supervision in selected public primary schools in Bagamoyo District, Tanzania. The study was guided by Social Constructivist Theory and employed a qualitative case study design, with Bagamoyo District as the bounded case and four selected public primary schools as embedded units of analysis. A total of 34 participants, comprising 28 classroom teachers, four head teachers, and two Ward Education Officers, were purposively selected. The findings revealed that collaborative lesson planning was widely practiced in the selected schools through joint preparation of lesson plans, discussion of learning objectives and teaching strategies, development of teaching aids, and sharing of instructional knowledge and resources. Teachers reported that these practices enhanced professional learning, teaching confidence, pedagogical knowledge, and collective problem-solving. However, the implementation of collaborative lesson planning was constrained by heavy teaching workloads, limited time, inadequate instructional resources, and competing administrative responsibilities.
