The research is conducted with a pretest-posttest non-equivalent control group design, focusing on finding the answers to two research questions: a) What are the significant differences between the quality of arguments written by students who use question prompt scaffolding and those who teach with an expository method? b) What are the significant differences between the quality of arguments written by students with high, moderate, and low language abilities? Data is gathered by conducting pre- and post-argumentative tests, which is scored with an adapted version of the Rubric of Argument Quality from Cho and Jonassen (2002). The scores of the quality of students‟ arguments are then analyzed with a mean differential analysis. The results of the study indicate that: a) there are significant differences between the quality of arguments written by students who use question prompt scaffolding and those who teach with an expository method; b) there are no significant differences between the quality of arguments written by students with high, moderate, and low language abilities. %I Program Pascasarjana Universitas Negeri Yogyakarta %J Seminar Nasional dan Temu Alumni "Peran Pendidikan dalam Pembangunan Karakter Bangsa" %D 2014 %T THE EFFECT OF QUESTION PROMPTING AND LANGUANGE ABILITY ON THE QUALITY OF STUDENTS‟ ARGUMENTS
