Abstract

Penelitian tindakan kelas ini bertujuan untuk meningkatkan kemampuan siswa dalam menulis teks recount menggunakan media Amplop Misteri. Subjek penelitian ini adalah 30 siswa kelas delapan kelas VIII-2 di UPTD SMPN 6 Kisaran. Penelitian ini dilakukan dalam dua siklus selama empat pertemuan. Awalnya, siswa menghadapi kesulitan dalam menghasilkan ide dan mengaturnya secara koheren. Setelah menerapkan strategi Amplop Misteri, kemampuan menulis mereka meningkat. Siswa menerima tugas berbasis amplop yang dirancang untuk membimbing mereka dalam menyusun teks recount melalui kegiatan yang menarik dan terstruktur. Skor rata-rata meningkat dari 66,1 pada Tes I menjadi 72,1 pada Tes II, dan 82 pada Tes III. Selain itu, persentase siswa yang mendapat skor ≥75 naik dari 13,3% menjadi 93,3%. Data kuantitatif dan kualitatif menunjukkan bahwa Amplop Misteri secara efektif meningkatkan keterampilan menulis recount dan keterlibatan siswa di kelas.

Abstract

This study aims to analyze the Computational Thinking (CT) abilities of prospective mathematics teacher students enrolled in the Teacher Professional Education Program at Universitas Islam Sumatera Utara. Using a descriptive quantitative approach, CT abilities were examined based on four main indicators: decomposition, pattern recognition, abstraction, and algorithmic thinking. Data were collected through contextual open-ended tests, perception questionnaires, and limited interviews involving 24 PPG students. The results showed that, in general, students' CT abilities fell into the moderate category, with the highest achievement in pattern recognition and the lowest in abstraction. Most students had never received explicit instruction in CT, yet acknowledged that this approach helped them solve mathematical problems more systematically. These findings highlight the importance of explicitly integrating CT skills into mathematics education curricula through problem-based and digital literacy-oriented learning approaches. The study recommends strengthening instructional strategies to develop students’ systematic and logical thinking abilities as future mathematics educators.
