Efektivitas Model Project Based Learning Berbantuan Media Wordwall Dalam Meningkatkan Keterampilan Menulis Teks Surat Pribadi dan Surat Resmi pada Murid Kelas VII Sekolah Menengah Pertama

Abstract

This classroom action research aimed to improve students' writing skills in composing personal and official letters through the implementation of the Project Based Learning (PjBL) model assisted by the interactive Wordwall medium among seventh-grade students of a junior high school. The research was conducted in three cycles consisting of planning, action implementation, observation, and reflection. The research subjects were 31 students. Data were collected through observation, interviews, documentation, and learning outcome assessments. The data were analyzed descriptively by comparing the students' mean scores and learning mastery percentages at each stage of the research. The results showed a gradual improvement in students' learning outcomes. In the initial condition, the students' mean score was 60.48, with a classical mastery percentage of 12.9%. After the implementation of the action in Cycle I, the mean score increased to 72.26, with a mastery percentage of 51.6%. In Cycle II, the mean score increased to 79.52, with a mastery percentage of 83.9%. Furthermore, in Cycle III, the mean score reached 83.71, with a classical mastery percentage of 93.5%. These improvements indicate that the implementation of the PjBL model assisted by Wordwall can support the improvement of students' writing skills in composing personal and official letters. The action research was considered successful because the classical mastery percentage in Cycle III exceeded the predetermined success indicator, namely at least 80% of students achieving a minimum score of 78.
