Abstract

This research related to analytical frameworks for assessing scientific argumentation in the last two decades showed that it has not developed much and was still very limited, especially in the context of Environmental Physics material which was oriented towards socio-scientific issues. In the curriculum structure of Department of Physics Education, Faculty of Teaching Training and Education, University of Muhammadiyah Makassar, Environmental Physics course is one of the compulsory subject groups with a total credit load of 3 credits. Several research results have tried to develop various forms of instruments to measure argumentation skills but have weaknesses in their implementation in the field because they were only based on transcripts. Furthermore, the development of an argumentative assessment that can measure students^ scientific argumentation skills that are oriented towards socio-scientific issues, especially in Environmental Physics course, has never been carried out. For this reason, it is necessary to develop an argumentative assessment oriented towards socio-scientific issues that is implementable, comprehensive and effective in measuring students^ scientific argumentation skills. This research is a developmental research using The Design Based Research stage model which consists of five stages, namely developing an assessment framework, designing items, developing rubrics, conducting trials, and applying the Racsh Model analysis. The application of the Racsh Model analysis aims to obtain a valid and reliable instrument using the Item Response Theory (IRT) approach assisted by the Winsteps version 3.6.2 program. The output of this research is an argumentative assessment oriented to socio-scientific issues that is appropriate for use (standard) in Environmental Physics course
