Impacts of integrating engineering design process into STEM makerspace on renewable energy unit to foster students' system thinking skills.

Currently, science education systems around the world are faced with global challenges, especially in anticipating environmental changes related to sustainable development programs. Complex system problems related to climate change, reduced fossil-based energy reserves, and social environmental problems that have an impact on the economy have made stakeholders aware of the Education for Sustainability Development (ESD) program. This study aims to examine the effectiveness of STEM-PBL integrated Engineering Design Process (EDP) in renewable energy learning units to improve students' system thinking skills.
