Effectiveness and Challenges of Differentiated Learning in Secondary School: A systematic literature review review

This systematic review of the literature discusses the effectiveness and challenges of implementing differentiated learning (DI) in secondary schools. This study analyzed 16 articles published between 2019 and 2023 using the PRISMA protocol. The study's results show that DI is effective in improving academic achievement and student engagement, particularly in the classroom with diverse abilities. However, the main challenges include a lack of teacher training, limited resources, large class sizes, and insufficient planning time. The success of DI is supported by collaboration between teachers, professional training, and a positive attitude towards inclusion. This study suggests further research for practical training for teachers and long-term evaluation of DI, especially in developing countries and online learning
