Dissertation (MA Education)This study assessed the impact of menstrual hygiene management on adolescent girls‘ learning particiaption in Tanzania focusing on secondary schools in Mbarali district. This study was realized by three specific objectives: to explore the adolescent girls‘ exprience during menstruation period in secondary schools; to identify challenges of MHM to adolescent girls on learning participation in secondary schools; and to determine the strategies of MHM among adolescent girls contributing to learning participation in secondary schools. This study was guided by the Goal Setting Theory (GST). Moreover, the study employed mixed research approach in which both qualitative and quantitative methods were used; and it employed cross-sectional research design. The sample size was constituted by 101 respondents drawn from Mbarali district, who included parents, adolescent girls and the school management. Data collection was done through semi-structured interviews, structured questionnaires, and documentary review. The findings of this study revealed the expriences of adolescent girl students such as missing school, underperformance in academics, and living with negative experience due to poor MHM. The study also found that, lack of menstrual hygiene management materials; poor infrastructure; lack of knowledge of MHM among teachers, parents and adolescent girl students; and lack of enough budget allocation in the schools were the main challenges of MHM among adolescent girls‘ participation in learning in secondary schools. Finally, the study recommends that, for the improvement of MHM, there should be menstrual management materials in schools; MHM education to adolescent girls; and supportive infrastructure like toilets, bathrooms, matron room, changing room, water system and packages in secondary schools.
