PENINGKATAN KETERAMPILAN MENULIS TEKS BIOGRAFI MENGGUNAKAN MEDIA VISUAL PADA SISWA KELAS X SMAN 14 MEDAN

Abstract

This study aims to improve the biography writing skills of tenth-grade students at SMAN 14 Medan through the use of visual media. The problem addressed is the students’ low proficiency in writing biographical texts, which stems from a lack of understanding of text structure and low engagement with conventional teaching methods. This research is a Classroom Action Research (CAR) conducted in two cycles, each consisting of planning, action, observation, and reflection stages. The research subjects were 33 students from class X-2. Data were collected through writing tests, observation, and documentation. The results showed a significant improvement in students’ writing abilities. The average score increased from 61.91 in the pre-test to 74.41 in the first cycle, and reached 85.74 in the second cycle. The percentage of students who met the minimum learning criteria rose from 26.47% in the pre-test to 70.59% in the first cycle, and reached 91.18% in the second cycle. Visual media such as infographics and animated videos effectively helped students understand the life stories of figures and encouraged their creativity in writing. It can be concluded that the use of visual media is effective in enhancing students’ biography writing skills. This study recommends the integration of visual media as an alternative instructional strategy in Bahasa Indonesia classes, particularly in writing lessons.
