Abstract

In problem-based learning (PBL), complex, real-world problems motivate students to discover interconnections between important concepts and in doing so acquire essential skills. These skills include teamwork, problem solving, information retrieval and analysis, and communication. The activity presented here suggests a way to add a “hands on” component to PBL by integrating a problem with a guided inquiry exercise. Problem resolution depends on observations made in the laboratory, using probes and computer data acquisition systems. Content topics that students will explore in the course of the exercise include C3 and C4 photosynthesis, global carbon cycles, and global warming.
