This document discusses different teaching approaches including constructivism, cooperative learning, inquiry-based learning, and contextualized learning. Constructivism holds that people build knowledge through experiences and interactions. Cooperative learning involves students working together to solve problems or tasks in small groups. Inquiry-based learning has students construct their own knowledge through experiences rather than being passive receivers of information from the teacher. Contextualized learning places learning in real-world contexts to make it more meaningful and engaging for students.
