The document discusses inquiry and problem-solving approaches to teaching. It notes that inquiry approaches model the investigative processes of scientists, allowing students to explore, ask questions, and form their own conclusions. Problem-solving approaches employ the scientific method, having students define problems, form hypotheses, test them through experiments or data collection, analyze evidence, and form conclusions. Both approaches aim to actively engage students in investigating concepts rather than simply being told information. They promote skills like critical thinking and develop scientific attitudes.
