A teaching module for blackbody radiation using the continuous spectra of stars

Abstract

Abstract Teaching blackbody radiation within the framework of astrophysics can motivate students to learn and obtain a more profound and qualitative understanding of the subject. In this paper we present a teaching module that intertwines teaching blackbody radiation via the continuous spectrum of hot objects, especially the stars. The module’s approach was that of guided inquiry. Students of upper secondary education carried out experimental activities that included a combination of hands-on activities and computer processing. They actively and creatively engaged in the activities which helped them develop a more complex and structured knowledge of the subject. A ten-multiple choice questionnaire was administered before and after the implementation and the data were qualitatively and quantitatively analyzed. The results showed that the intervention had a significant impact on students’ learning outcomes.
