The document discusses case studies, problem-based learning, and project-based learning approaches to teaching. It provides examples of using real-life cases and projects to teach science topics like physics and the creation of elements. Case studies present problems for students to analyze from narratives about real situations. Creating effective cases involves finding current stories on the topic and collecting multiple resources to make the story engaging. Project-based learning also engages students by giving them real problems to explore within an overarching theme. Both approaches aim to construct student knowledge through experience with authentic scenarios.
