This paper examines geometric optics within the context of physics lessons and the education system in general. The role of the State Matura exam within the students' education process is closely analysed as well as the role of geometric optics within the Matura exam. The focus is particularly put on the knowledge and skills of geometric optics that are students required to master through their secondary education. As an innovative idea the usage of free applications and programmes, such as Kahoot! and Algodoo, is introduced. A free gamebased learning platform Kahoot! enabled the author to create an example of a test whose purpose is to motivate students to cooperate and actively learn through play while also giving the teacher a feedback on students' assessment. On the other hand, Algodoo programme provides better visualisation of the chosen topic problems so as to achieve a more suitable methodological approach to the topic itself. Finally, the purpose of this paper is to display a different approach to the teaching of geometric optics which can not only improve the classroom activities but also consequently improve the very education system.
