Dissertation (MA Education)The study examined the contribution of school heads on teachers` motivation in Tanzania from the perception and experiences of school heads and teachers of four selected ward based secondary schools in Mafinga town council. Herzberg’s Two Factor theory was used as theoretical framework. The study responded to specific objectives by: identifying and examining the most effective factors that motivate teachers, examine the strategies employed by schools heads in motivating teachers and determine the constraints that face schools heads in the implementation of teacher’s motivation strategies in ward- based secondary schools. Questionnaires, interviews and documentary review were used to collect data from 44 teachers and schools heads from 4 ward based- secondary schools in Mafinga town council. The results of the findings have revealed that the most effective factors for teachers` motivation were: good working condition, financial compensation, work promotion, community’s perception and secondary education policy. The most effective strategies for the school heads to use were: provision of teaching and learning materials and resources, involving teachers in decision making, supervision, professional development and rewarding system; while among the constraints faced the schools heads in the implementation of teachers` motivation strategies was the insufficient of fund. This study recommends that schools heads should ensure the improvement of school environment as well as bolstering teachers‟ capability to develop teaching and learning materials. The study suggests that the Ministry of Education and Vocational Training should ensure timely remuneration of teachers and devise a way to generate income that can be used to pay allowances for the teachers who work beyond the allocated time.
