The Development of Reasonable Argumentation Skill by Using Socio-Scientific Issue (SSI)

Abstract

This action research aims to develop student argumentation skills through instruction in Socio-scientific Issue (SSI)-Based Teaching to pass the criteria at a good level of 24 students in Mathayomsuksa 5 students. The target group is Mathayomsuksa 4 students. The research instruments consisted of 1) nine lesson plans, operating cycle 1 has 4 plans and cycle 2 has 5 plans. The duration of the research was 13 hours 2) argumentation skills test open-ended assessment. There are 6 situations, 30 questions. the 5 level measurement criteria were very low level, low level, medium level, good level and very good level. The consistency index is in the range of 0.8-1.00. 3) student behavior observation, consistency index value 0.8-1.0 and 4) interview form had a consistency index in the range of 0.6-1.00. The quantitative data were analyzed by means and standard deviation, as well as the qualitative data was analyzed by content analysis.
            The results from the first learning cycle found that 17 students passed the criteria. The mean was 6.50 with argumentation skills passing as good. Because students have problems understanding the content they study. Or write to explain the reason for choosing the answer to show the misunderstanding from the study. And about the time spent doing activities that are quite limited, making some activities not possible in time, the learners are still unable to tell the reasons for supporting them. There can be more than one reason. Therefore, teaching and learning by presenting social issues related to science as a basis. Through video media, role-playing, and debating, students can gain knowledge from a variety of learning sources. The results from the second learning cycle found that 22 students passed the criteria for rational argumentation skills. The mean was 6.83 and argumentation skills were good.  From the results of this study, it can be concluded that science-based social-issue learning can develop students' rational argument skills.
