Analysis of Students' Scientific Argumentation Skills in the Toulmin's Argumentation Pattern (TAP)-Based Learning Model in Understanding Physics Concepts with the Library Research Method]The aims of this study was to describe the application of Toulmin's Argumentation Pattern (TAP) learning model in Physics. Observations focused on the impact of increasing students' conceptual understanding and argumentation skills in the field of physics. This research uses the library research method. The research was carried out by collecting journal data and scientific articles published online and indexed by the Google Scholar page, downloading, and then organizing the articles in the Mendeley application. In reviewing scientific journals, this research is carried out following the following steps: (1) Organize, which is to select the types of journals that are in line with the type of research; (2) Synthesize, namely reading and summarizing each journal into a coherent and structured research essence; and (3) Identify, namely drawing conclusions from each journal and making a summary evaluation of the entire journal. Based of the results from the study, was found that the application of Toulmin's Argument Pattern (TAP)-based learning can improve argumentation skills and understanding of concepts, especially in the field of physics. The results of a review of previous research by researchers can be concluded that learning based on Toulmin's Argumentation Pattern has advantages: it affects argumentation skills, increases the strengthening and acceleration of understanding concepts, builds better argumentation patterns, improves the quality of argumentation, and creates creative and innovative students in development. the material in the learning. As for the shortcomings of this argumentation learning model, there is the initial obligation of students to have a good literacy foundation.
