“…Therefore, different ways of improving the quality of education and teaching are constantly sought. A number of measures are taken to improve the quality of teaching and the overall development of the educational process in schools: improvement of the curriculum (Metz, 1997), continuous professional development of teaching staff through in-service education, training and advisory work (Watson, Steele, Vozzo, & Aubusson, 2007;Wilson, 2000), introducing information technology in teaching (Ardac & Akaygun, 2004;Barbour & Reeves, 2009;Carvalho-Knighton & Keen-Rocha, 2007), improving textbooks and other literature, improving working conditions and providing teaching and learning resources and other equipment (Vosniadou, Ioannides, Dimitrakopoulou, & Papademetriou, 2001), extending the duration of regular institutional education, as well as empowering pupils and developing self-education habits (Demirdogen & Cakmakci, 2014). Certainly, the teacher has a key role in overall educational work, especially in the planning, organisation and realisation of teaching, and thus in the process of forming conceptual, quality knowledge among pupils.…”
