Learning Trajectories Toward Energy Understanding
Energy literacy consists of two main components: energy knowledge and the ability to apply this knowledge, i.e. energy understanding. Developing energy understanding requires students to integrate energy ideas, such as energy transformation, into a well-integrated energy knowledge network. Research …
