Impact of teacher professional development on student achievement with a focus on Bosnia and Herzegovina: Analyzing TIMSS 2019 results in Western Balkan countries and Croatia

Abstract

Students in Bosnia and Herzegovina (B&H) score very low on international assessments (TIMSS & PISA), lower than the countries in the region with which it shares similar background. In this paper the characteristics of teachers’ professional development (TPD) in the region of Western Balkan countries (Albania, B&H, Kosovo, Montenegro, North Macedonia, and Serbia) and Croatia are brought into correlation with average results in mathematics and science on TIMSS 2019. Research questions analyze teachers’ attitudes towards their profession and investigate the impact of professional development (PD) of mathematics and science teachers in the last two years, with a specific focus on the situation in B&H, on students’ achievement in mathematics and science. The findings indicate a lack of TPD as a contributing factor to lower results in B&H. The research suggests that B&H should consider reforms in the education system and enhance teachers’ attitudes towards their profession through intensified PD programs to advance education and learning.
