Abstract

Stagnasi keterlibatan siswa dalam pembelajaran Pendidikan Kewarganegaraan di jenjang vokasi kerap mereduksi esensi mata pelajaran ini menjadi sekadar transfer pengetahuan tekstual, sehingga aspek daya kritis dan kolaborasi sosial kurang terfasilitasi secara optimal. Penelitian ini bertujuan untuk menganalisis pengaruh penerapan model pembelajaran kooperatif tipe Group Investigation (GI) terhadap hasil belajar Pendidikan Kewarganegaraan siswa. Penelitian menggunakan pendekatan kuantitatif dengan desain one group pretest–posttest yang diterapkan pada siswa kelas X SMK Swasta 1 Tamansiswa Pematangsiantar. Intervensi pembelajaran difokuskan pada transformasi peran siswa dari pendengar pasif menjadi investigator aktif melalui kegiatan penelusuran masalah, diskusi kelompok, dan sintesis temuan secara kolektif. Hasil analisis menunjukkan adanya pergeseran capaian akademik yang bermakna setelah intervensi, dengan peningkatan hasil belajar yang berlangsung secara konsisten pada seluruh subjek penelitian dan berada pada kategori efektivitas sedang. Temuan ini menunjukkan bahwa integrasi investigasi terstruktur dalam pembelajaran kooperatif berpotensi memperkuat kualitas pembelajaran PKn di lingkungan vokasi, meskipun interpretasi hasil tetap dibatasi oleh penggunaan desain penelitian tanpa kelompok pembanding.

Abstract

This study aims to provide an in-depth understanding of the experiences of students from the Program at HKBP Nommensen University Pematangsiantar during their Field Teaching Practice (PPL) at Taman Madya (Private) Tamansiswa Senior High School in the 2025 academic year. Over fourteen weeks (August 20–December 10, 2025), the students engaged in teaching activities, lesson plan development, and non-instructional programs within the framework of the Merdeka Curriculum (Independent Curriculum). Employing a narrative study approach, this research positions student experiences as the primary data source to explore reflective learning processes and the formation of professional teacher identity. The findings reveal that PPL serves as a dialectical space where pedagogical theories learned at the university intersect with the dynamic social realities of the school environment. Three key findings emerged: first, the consistency between theory and practice is expressed through the students’ reflective capacity to interpret and adapt theoretical knowledge to contextual realities; second, the mentoring relationship between student teachers and supervising teachers demonstrates a shift from hierarchical supervision toward collaborative partnership that fosters mutual learning; and third, student teachers’ responses to contemporary educational issues—particularly digitalization and the Merdeka Curriculum—encourage the development of technology-based learning innovations and critical literacy practices. The study concludes that PPL not only equips student teachers with instructional competencies but also cultivates professional awareness, pedagogical autonomy, and social sensitivity—qualities that form the foundation of effective and human-centered teachers in an era of educational transformation.
