Possibilities and limits of student activation in chemistry education at lower secondary school using didactic games: Particle composition of substances

The diploma thesis deals with the possibilities of activating elementary school students in the topic of particle composition of substances using didactic games. The theoretical part discusses selected significant experts who have dealt with activation in the past, defines the concepts of activity and activation, and their importance in pedagogical practice. It also presents teaching methods and their possible classification, with a particular emphasis on didactic games (their definition, categorization, and significance). Subsequently, an analysis of critical topics in chemistry education at the elementary school level follows, within which a specific area of content ("particle composition of substances") was identified and for which individual didactic games were created. The topic of "particle composition of substances" is further analysed across several currently most used textbooks. The last chapter of the theoretical part focuses on introducing the so-called constructional research, which was chosen as the research method utilised for the purposes of didactic games creation. In the practical part, six protypes of didactic games were developed, which were subsequently modified based on feedback from two experts in the field of chemistry didactics, four experienced chemistry teachers, and their..
