Klaten.
Penelitian ini menggunakan pendekatan Penelitian Tindakan Kelas (Classroom
Action Research), yaitu penelitian kolaboratif antara guru dan peneliti untuk mengatasi
permasalahan yang ada dalam pembelajaran. Sumber data penelitian ini antara lain:
peristiwa proses pembelajaran menulis teks eksplanasi, informan (guru pengampu mata
pelajaran Bahasa Indonesia, siswa kelas VII H SMP N 2 Klaten), dokumen (Rencana
Pelaksanaan Pembelajaran, foto kegiatan pembelajaran, hasil mind mapping, teks
eksplanasi). Teknik pengumpulan data yang digunakan adalah observasi, angket,
wawancara dan tes. Untuk menguji validitas data peneliti menggunakan teknik
triangulasi sumber data. Data yang terkumpul dianalisis dengan menggunakan analisis
kritis berdasarkan indikator keberhasilan yang telah ditetapkan. Proses penelitian
dilaksanakan dalam dua siklus dengan empat tahap pada tiap siklusnya, yaitu tahap
