Physical education has been the subject of research for a long time. Research focuses most often on the use of time to get pupils to move actively or on their physical load during a lesson.
The evaluation of the didactic interaction of the teaching student - pupil(s) is also an essential area of research. The aim of the paper is to introduce the MADI method and its subsequent use in the evaluation of didactic outputs of teaching students in subjects focused on the didactics of swimming.
The method Analysis of Didactic Interaction (ADI) has been modified to assess didactic interactions between the teaching (student) - pupil(s). Modified Analysis of Didactic Interaction (MADI) was created by reducing the number of monitored categories and focusing attention on the activity of the student.
The achieved results showed that the most frequent form of behaviour among the students was observation followed by instruction. This influenced both the form of their manifestations, dominated by silence, and the overall manifestation, which was neutral and mostly without material significance.
In terms of activities that have been the subject of didactic interaction, students have been taught these activities. The results obtained show that the chosen method seems to be effective for evaluation of didactic output of teaching students.
A deeper analysis of student didactic outcomes can contribute to influencing the quality of student didactic competencies. At the same time, it can also serve as a feedback tool on their didactic activities for their faculty teachers.
