School-based teaching for democracy: A systematic review of teaching methods in quantitative intervention studies

Abstract

Effective teaching for democracy requires an understanding of the teaching methods and educational characteristics that are effective in interventions. In order to address this requirement, we conducted a systematic literature review. We used an extensive search syntax and snowballing method that allowed us to find n = 2093 unique publications. After a screening process, we have included 54 interventions in 51 different quantitative effect studies written between 2010 and 2020. We categorized these interventions into five types of teaching methods: instruction, small-group work, assignments, projects, and democratic decision-making. We analyzed what the educational characteristics (i.e., subject matter, classroom interaction, classroom management) of these interventions were and for which democratic competences (i.e., knowledge, attitude, skill, behavior) they were effective. Our results show that teaching methods have differential effects on democratic competences. We also discuss the robustness of these results. Our study shows that there is still much to be gained in terms of research designs, the conceptualization of democratic competences, and the description of teaching methods.
