The diploma thesis on the topic "Teaching of Economics at a Secondary Vocational School from the Didactics of Social Sciences Perspective" is divided into two parts. The first part is a theoretical one, where the author defines the theoretical didactic concepts in detail, and they are then used in the second, practical part of the thesis. This part presents a proposal of a didactic unit, which deals with the teaching of wage calculation. It includes a worksheet and methodical sheet as well, the detailed didactic preparation and detailed reflection of the implemented didactic unit in the classroom and online teaching. Repeatedly practising this didactic unit, it can be noted that the proposed form of teaching is effective and accepted by students. Personal and social skills, mathematical skills and critical thinking training also go beyond the main topic.
