Flipped Classroom Setting, Socio-Scientific Issues, STEM Learning Activity SheetsAbstract
This study designed, validated, and evaluated SSI-integrated STEM Learning Activity Sheets (LAS) for Grade 10 Science on human evolution, structured around the 7E instructional model and a flipped classroom to develop the 4Cs through three sequential lessons. Expert validation rated the LAS highly in content, organization, design, and reliability (Cronbach’s ? = 0.70–0.99; S-CVI/Ave = 1.00), while pilot testing showed significant learning gains with medium normalized improvements (Hake’s g = 0.32–0.35) and very large effect sizes (Cohen’s d = 2.52–3.93). Student feedback indicated high engagement with interactive, collaborative, and multimedia activities, with suggestions for additional visuals, structured reflections, improved pacing, and more group-based tasks, supporting the LAS as effective, valid, and reliable tools aligned with the MATATAG Science Curriculum and offering potential for refinement and broader application.
