This research explores the application of educational technology (EdTech) tools and platforms in STEM education within Swedish schools and their impact on student learning outcomes. Employing a mixed-methods approach, the study includes quantitative surveys and qualitative interviews with teachers, students, and education experts across various institutions, including urban schools in Stockholm and Lund University, as well as rural schools in Jämtland and Norrbotten. Data collection commences in January 2024 and concludes by March 2024, encompassing direct observations, analysis of student performance, and structured interviews. The research aims to identify the most commonly used EdTech tools, evaluate their effectiveness in enhancing student engagement and comprehension, and examine the challenges educators face in implementing these technologies. By focusing on Sweden's innovative EdTech integration, the study seeks to provide insights that inform policymakers and educators in improving STEM education, addressing barriers such as teacher training and resource availability. The findings contribute valuable lessons for other countries and have broader implications for the global push towards digitalization in education and the future of STEM learning.
