Ways for self development of teaching strategy Abstract: The aim of this thesis is to analyse the diagnostic tools designed by M. Hejny and his team. These tools focus on teaching styles in education, observing the personal development of a mathematics intern teacher. The study materials i have obtained during my practice are used to describe and analyse the teacher's educational style, with the use of twenty defining parameters. My thesis is based on Gabriela Hlavata's master thesis, a teacher who describes her own shift from transmissible to constructive teaching in mathematics classes. Hlavata depicts this shift clearly, hence the reason I have decided to describe it with a set of parameters measuring the intern teacher's educational style. The subsequent aim is to trace my own evolution in teaching mathematics. Practice and materials gained in my graduation, together with the twenty educational parameters as outlined in my thesis, will serve to analyse and describe my own educational style. In choosing this topic, I am trying to answer the following question; whether the observation of a teacher's educational style will impact on the delivery and quality of mathematics lessons? Furthermore, is improvement possible, or have I reached the capacity of my own teaching ability? Additionally this thesis...
