Pengaruh Scaffolding dan Kecakapan Berbahasa Indonesia terhadap Kualitas Argumen Mahasiswa

Abstract

This experiment examines the effect of scaffolding (question prompts and argument mapping) on the quality of arguments written by students with high, moderate and low language abilities. The experiment was conducted in Pre test-Posttest Non Equivalent Control Croup Design, focusing on finding the answers to three research questions : a) is there any significant difference between the quality of argument written by students who were scafolded by question prompts and by giving argument mapping, b) is there any significant difference between the quality of argument written by students with high, moderate and low language abilities, and c) is there any interaction between scaffolding and student language abilities to determine the quality of arguments written by students in both classes of experiment. Three hypotheses that are tested in this study are: a) there is a significant difference between the quality of arguments written by students scafolded by question prompts and by argument mapping, b) there is a significant difference between the quality of arguments written by students with high, moderate and low language abilities, and c) there is an interaction between scaffolding and student language abilities in determining the quality of arguments written by students in both classes of experiment. Data were gathered by conducting pre- and post-argumentative test, which is scored with the Rubric of Argument Quality adopted from Cho and Jonassen (2002). The scores of the quality of students arguments were than analyzed with an analysis of variance. The result of study indicate that: a) there is no significant difference between the quality of arguments written by students scafolded by question prompts and by argument mapping, b) there is significant difference between the quality of the arguments written by students with high, moderate and low language abilities, and c) there is no interaction between scaffolding and students' language abilities in determining the quality of the arguments written by students in both classes of experiment.
