In today's global society, learners are shifting their roles from passive recipients of knowledge to active participants in creating knowledge themselves. This necessitates that teachers encourage students to engage in higher-order thinking, discussions, interactions, and hands-on activities according to individual differences. Therefore, proactive learning materials in social studies are crucial guidelines that teachers can use to align with 21st-century classrooms. This approach aims to develop students' knowledge, skills, and attitudes for happy learning while solving problems when facing real-life situations.
