Dissertation (MA Public Administration)The teaching environment is a vital factor towards provision of quality education and the contribution of SEDP is expected to be an important addition to improve the teaching environment in Tanzania secondary schools. The study aimed at assessing the contribution of Secondary Education Development Programme (SEDP) to the improvement of teaching-learning environment in Tanzania by using public secondary schools in Dodoma municipality as a case study. The literature reviewed has revealed that various programs including SEDP aim at improving teaching-learning environment as vital factor in enhancing the provision of quality education. However, the study found out that the situation was not pleasing to support students‟ academic performance. A survey and interview methods were used for data collection by using questionnaires and interview checklist. Excel and Statistical and Package for Social Sciences (SPSS) were used to analyze the data which also descriptions from informants were utilized. The findings observed that the success of the programme included the increase of enrollment rate of students to schools, reduced the problem of the deficit of desks and improved equity to secondary school to all Tanzanians. However, SEDP is still facing various problems including poor disbursement of funds to schools, lack of enough teachers, inadequate or lack of teaching- learning facilities, poor teachers‟ motivation and overcrowded classrooms. It can be concluded that much efforts are still needed to enhance the process of improving teaching-learning environment to secondary schools. The researcher recommends some changes of mind set by educating education stakeholders on the need to contribute towards education projects and the government must provide reasonable fund to schools.
