Abstract
Arguments are very important in the presentation of teaching materials. Presentation of the material in an argumentative manner will make it easier for students to understand the teaching materials. The purposes of the study are to describe and explain Toulmin^s argument patterns, their percentages, the quality of arguments, and incorrect arguments in the redox reactions and electrochemistry topic of one high school chemistry textbook. This research method was document analysis. Validity was tested by triangulation among three researchers. The results showed that the patterns of Toulmin^s arguments of two, three, and four elements were 51%, 34%, and 6%, respectively. The two-element argument patterns consisted of CG and GC. The three-element argument patterns consisted of CGW, GWC, CWG, WCG, and GCW. The four-element argument patterns consisted of GCWB, CGWB, GWCB, and CGWR. The quality of the arguments according to the parameters of the Toulmin Argumentation Protocols (TAP) varied from medium to high, while the quality based on the parameters of Quality of Argument Structure Rubric (QASR) varied from fair to excellent. There are five claims, eight grounds, and two warrants that were not precise or incomplete. Most of the arguments were well written, but there were many shortcomings in providing explanations. This topic needs to be supplemented with more elements of argument.
