Flipped learning and interactive methods with smartphones in modern physics at secondary schools

We present an example of an active learning activity in modern physics at secondary school developed by us in the framework of flipped learning. The activity dealing with the black-body radiation was a part of our experimental course of modern physics at one of Slovak grammar schools. Using an inquiry-based form of the activity with an interactive demonstration as its introduction, students actively learned modern physics with a GeoGebra simulation as a fundamental tool of visualization, experimentation and measurement. Our results show that thanks to interactive simulations the interactive methods in the framework of flipped modern physics can be really viable, even in classical classrooms with currently widely available digital technologies – smartphones and a Wi-Fi connection.
