摘要：The effectiveness of the problem based teaching on the science learning has been highlighted by the didactic research. This teaching model is characterized by organizing the units around problems and by proposing a research plan to find a solution which requires concepts and models to be introduced in a functional way, as possible solutions to the problem. In this article we present a problem based unit for teaching quantum physics in introductory physics courses and we analyze in detail the teaching strategy that we follow to build a model to explain the emission and absorption of radiation.
