This study examines how pre-service elementary school teachers participating in school sports
clubs as a leaders reflect on their teaching and what efforts they make to improve their
professionalism through the practical structure of knowledge (Elbaz, 1983). The results indicate
that they imagine themselves of ‘managers of student interest’ with regard to knowledge. The
pre-service elementary school teachers create this image through the principles: “I should be a
leader who can communicate and share feelings with students,” and “I should introspectively
reflect on myself.” Their image of the knowledge of teaching and the learning environment was
‘an individual- and game-centered class’. It was developed through the principles: “There are
many parents observing the class,” and “I should pay attention to the present condition of student
registration.” The image of curriculum knowledge was ‘an emphasis on character and challenge’.
They visualized it as: ‘personal egoism prevails’ and “I can know about myself precisely.” Their
image of teaching and learning knowledge was ‘an authoritarian disciplining method’. This
became specific through the principles: “The control over the students needs to be reinforced,”
and “I think a lot about how to guide the students.” Images of positive synergy, partially positive
and negative synergy, negative synergy, and so on among the characteristics of the pre-service
elementary school teachers’ practical knowledge appeared in the knowledge of the teachers
themselves, the curriculum content, and teaching and learning. Finally, if the practical knowledge
of school sports club leaders of other areas is investigated, they could be compared with
experienced leaders of school sports clubs; and if the practical knowledge of the administrators of
school sports clubs is researched, school sports clubs will be able to be understood in more depth.
