PENINGKATAN KETERAMPILAN MENULIS TEKS ARGUMENTASI MELALUI MEDIA SIGAP (SARANA INTERAKTIF GALI ARGUMENTASI DAN PENALARAN) PADA SISWA KELAS XI-6 SMAN 6 SURABAYA

Abstract

This classroom action research aims to describe the improvement in learning engagement and argumentative writing skills among students in Class XI-6 at SMAN 6 Surabaya through the use of the Canva-based SIGAP medium. This study was conducted in two cycles based on the Kemmis & McTaggart model and involved 31 students. Data were collected through individual writing performance tests and non-test methods (observations and documentation), then analyzed using descriptive qualitative and quantitative methods. The results showed that refining the SIGAP media through scaffolding features effectively improved the quality of students’ learning processes and outcomes. The average level of students’ independent engagement increased from 53.0% (Low) in Cycle I to 81.4% (Good) in Cycle II. This improvement in the quality of the learning process led to an increase in the average writing test score from 69.19 to 87.26. Meanwhile, the rate of mastery in the traditional learning setting surged dramatically from 38.71% (12 students) to 90.32% (28 students), exceeding the established success indicator (≥ 80%). Thus, the implementation of the scaffolding-based SIGAP medium proved effective in enhancing students’ engagement in the learning process and their skills in writing argumentative texts.
