In my thesis I focused on the effect of the course Basics of Social Science on the moral development of high school students and especially on the process of teachers’ moral effects on their students. The whole process was studied from the teachers’ perspective. I tried to answer the question whether the school subject Basics of Social Science can play significant role in student’s moral development. I used qualitative methods of content analysis and grounded theory. As another aspect of my work, I compared the situation of Czech teachers with the situation of Russian teachers in the corresponding Russian subject “obshchestvoznanie”.
