We have developed a lesson in which learners interactively construct a qualitative representation about climate change and the decline of biodiversity by using the online software DynaLearn.1 They are supported by a built-in support function to notice mistakes, and they can run simulations to explore system behavior. Throughout the lesson, learners are guided by a workbook providing necessary information step by step.
Climate change is a complex problem. There are several studies that describe common misconceptions of learners about the greenhouse effect and related processes.2–4 An example of this is that many learners do not perceive Earth as a radiating entity. Instead, they believe that the atmosphere is acting as a shield, trapping heat as “solar radiation.” Furthermore, learners frequently lack an understanding of the distinction between the natural and enhanced greenhouse effect.
To address complex problems such as climate change, it is important that learners understand how...
