The use of argument based science inquiry learning model by using science writing heuristic approach to build students argument ability in environmental pollution theme

Given the importance of the ability to argue for students in Natural Science learning, it was necessary to find a solution, which is a method and learning approaches that are expected to develop students' argumentation. One of the methods that could be apply was the Argument Based Science Inquiry (ABSI) learning model with Science Writing Heuristic (SWH) approach. The object of this study was learning natural science by using webbed-based with the theme of environmental pollution. This study aims to obtain a description of students' argument ability in SMPN 1 Malingping. This research was the Quasi Experimental research with Non Equivalent Pre-test Post-test Design type. The subject involved of students' class VII in SMPN 1 Malingping. Experimental class and control class were given the same test, they were pre-test and post-test. The results showed that the N gain score of students' argument ability in the experimental class was 0.40. While the value of N gain students' argument ability in the control, class is 0.25. The researcher recommended that this research should be done in schools that have excellent classes and regular classes in order to make comparisons clear.
