We report on the effectiveness of using interactive personal response systems in teaching physics in
secondary schools. Our research were conducted over the period of 2013–2016 using the system called
clickers. The idea is based on a reciprocal interaction allowing one to ask questions and receive
immediate responses from all the students simultaneously. Our investigation has confirmed this
method to be highly effective and powerful. In particular, students’ ability to acquire knowledge
increased with the time spent using clickers. We have successfully applied the system also to entire
physics courses. As a result, a positive feedback from students has been observed: not only did they
learn more but also the teachers were able to improve their own methods.
