Constructivism is a learning theory that suggests people build their own understanding and knowledge of the world through experiences and reflection. Instead of passively receiving information, learners actively engage with new ideas, connecting them to what they already know. This approach encourages critical thinking and problem-solving, making learning more meaningful and personalized. In a constructivist classroom, teachers act as facilitators, guiding students in their exploration. Activities often involve collaboration, hands-on projects, and real-world applications. This method aligns with the ideas of educational theorists like Jean Piaget and Lev Vygotsky, who emphasized the importance of social interaction and cognitive development in learning.
