The purpose of the research is to determine the effect of the Argumentation-Based Learning Model in developing the persuasive speaking skills of 7th grade students and their speaking motivation. The research was conducted based on action research, which is a process to determine and improve the quality of teaching in a real classroom environment. The study group of the research consists of 13 seventh grade students. The qualitative data of the research were obtained based on Toulmin’s Argument Classification Scheme, and the quantitative data were obtained using the Speaking Skills Attitude Scale. During the application process covering the 8th week, the speeches made by the students were recorded every week, and the argument levels were determined by analyzing the recorded speeches. Based on the scale, codes and categories were created. Maxqda 2020 data analysis program was used in the analysis of qualitative data. Attitude scores obtained with the Speaking Skills Attitude Scale were analyzed with the Wilcoxon Signed Ranks test. As a result of the research, it was determined that there was an increase in the arguments produced by the students in terms of quantity and quality and that there was a significant difference between the students’ attitudes towards speaking skills.
