Abstract:
The purpose of this study was to design and assess the use of Improvised Instructional
Materials (IIM) in teaching physics lessons in Tanga region whereby two Community
Secondary Schools (CSS) from Korogwe district and the city of Tanga were selected for
implementation of IIM. A total of eight teachers were selected from the sampled schools
where by each school provided two physics teachers. The researchers planned and prepared
the materials in advance before coaching the teachers on how to implement them. Teachers’
ability to execute student centered teaching approaches was assessed before and after
coaching. It was found out that the use of improvised instructional materials to run practical
lessons has refined and broadens teachers’ knowledge on designing and the use of such local
materials to carry out physics experiments in CSS.
