摘要：Tujuan dari penelitian ini adalah mengetahui efektivitas kunci determinasi bergambar dengan penerapan model STAD pada materi Plantae di SMA N 1 Suruh. Penelitian ini dilakukan di SMA N 1 Suruh di kelas XA,XB,dan XC. Pengambilan sampel dilakukan dengan teknik purposive sampling dengan desain penelitian One Shot Case Study. Data yang dikumpulkan berupa aktivitas siswa,hasil belajar siswa (tes akhir,tugas kelompok,dan nilai kuis),serta data tanggapan siswa dan guru. Data aktivitas siswa,tanggapan siswa,dan tanggapan guru dianalisis secara deskriptif kualitatif. Hasil penelitian penggunaan kunci determinasi bergambar dengan penerapan model STAD diperoleh ketuntasan klasikal keaktifan siswa pada kelas XA sebesar 86,84%,kelas XB sebesar 93,42%,dan kelas XC sebesar 94,74%. Rata-rata nilai hasil belajar siswa pada kelas XA sebesar 82,07,kelas XB sebesar 82,1 dan kelas XC sebesar 82,18. Berdasarkan hasil penelitian dapat ditarik kesimpulan bahwa penggunaan kunci determinasi bergambar dengan penerapan model STAD efektif diterapkan pada materi Plantae di SMA.
