Professional Development and Science Teacher Effectiveness in Africa: A Study of South Western Uganda. Kabale: Kabale University.http://hdl.handle.net/20.500.12493/2319Teacher Professional Development (TPD) has long been a factor in revolutionizing the quality of science education in Africa. Although the Ugandan government introduced many TPD initiatives, there have been noticeable failure rates in science subjects nationwide at the Uganda Certificate of Education (UCE) examinations. This study aims to interrogate the level of science teacher engagement in professional development, challenges hindering teacher access to TPD programs, and the correlation between TPD and teacher effectiveness regarding science grades. Using the Mixed method design, a sample size of 100 science teachers was recruited. The major findings revealed glaring gaps relating to inadequate teacher involvement in professional development, lack of planning for professional training of science teachers, limited funding, and negative attitudes towards professional development by science teachers and the school administration. The study proves that engagement in TPD positively correlates (π = 0.473, p < 0.01) with science teacher effectiveness. The study points to a critical argument that to deconstruct the narrative that STEM performance is supposed to be low and historically few students take on these disciplines, there is a need to invest in professional growth for science teachers.enAttribution-NonCommercial-NoDerivs 3.0 United Stateshttp://creativecommons.org/licenses/by-nc-nd/3.0/us/Professional DevelopmentTeacher EffectivenessSecondary SchoolsSouth Western UgandaScience Education in AfricaArticle
