The purpose of this study is to apply the Group investiagtion model assisted by Question Box media equipped with LKS Word Square. This research is a classroom action research (PTK) using a descriptive quantitative approach, which is carried out in three stages: pre-cycle, cycle I, and cycle II, involving 21 students. improvement of student learning outcomes from activities, In pre-cycle activities, a percentage of completeness of 40% was obtained, and incomplete as many as 15 students with a percentage of 60% In the assessment activity of affective activities of students with the highest predicate of 0%, medium predicate of 28%, and low predicate of 72%. In the first cycle, there were 15 students who completed with a percentage of 60%, and 10 students who did not complete with a percentage of 40%, with the highest score of 90 and the lowest score of 50. In the first cycle of the affective aspect assessment, scores were obtained with a high category of 16%, a medium category of 44%, and a low category of 40%. The learning outcomes of students experienced a significant increase in the first cycle compared to pre-cycle activities. In cycle II, there was another increase in posttest learning outcomes in cycle II for the cognitive aspect, namely there were 20 students who completed with a percentage of 80% and 5 students who did not complete with a percentage of 20% with the highest score of 100 and the lowest score of 20 and an average score of 80. The affective aspect obtained a percentage value with a high category of 90.62%, medium category 9.37%, low category 0%. The achievement of learning outcomes in cycle II is very satisfactory because many students get a score above KKM, which is 70. Based on the data obtained, there was a very high increase in learning outcomes in cycle II, which was 80%. This shows that the indicators of student success in this study have approached classical completeness, namely 85% of the number of students in the class obtained a score greater than or equal to 70 (KKM). It can be concluded that the application of the Group Investigation learning model with Question Box media equipped with LKS Word Square, can improve the learning outcomes of students at SMA Muhammadiyah Waingapu, class 1X Science on Plant Network material.Abstrak. Penelitian ini bertujuan untuk menerapkan model Group investigation   berbantuan media question box dilengkapi ygLKS Word Square. Penelitian ini merupakan penelitian tindakan kelas (PTK) dengan menggunakan pendekatan kuantitatif deskriptif, yang dilakukan dalam 2 tahap: siklus I, dan siklus II, melibatkan 21 siswa.  Peningkatan hasil belajar peserta didik pada siklus I, terdapat 15 peserta didik yang tuntas dengan persentase 60, dan 10 peserta didik yang tidak tuntas dengan persentase 40, dengan nilai tertinggi 90 dan nilai terendah 50.  Pada siklus I penilaian aspek afektif diperoleh nilai dengan kategori tinggi 16, kategori sedang 44, kategori rendah 40.  Hasil belajar peserta didik mengalami peningkatan yang signifikan pada siklus I dari pada kegiatan pra siklus. Pada siklus II terjadi lagi peningkatan hasil belajar posttes pada siklus II untuk aspek kognitif yaitu terdapat 20 orang peserta didik yang tuntas dengan persentase 80 dan 5 orang peserta didik yang tidak tuntas dengan persentase 20% dengan nilai tertinggi 100 dan nilai terendah 20 dan nilai rata-rata 80.  Aspek afektif diperoleh nilai persentase dengan kategori tinggi 90,62, kategori sedang 9,37, kategori rendah 0. Pencapaian hasil belajar pada siklus II sangat memuaskan karena banyak peserta didik yang mendapatkan nilai di atas KKM yaitu 70. Berdasarkan data yang diperoleh, Hal ini menunjukkan bahwa indikator keberhasilan peserta didik dalam penelitian ini telah mendekati ketuntasan klasikal yakni 85. Dapat disimpulkan bahwa penerapan model pembelajaran Group Investigation berbatuan media question box dilengkapi LKS Word Square, dapat meningkat hasil belajar siswa di SMA Muhammadiyah Waingapu.
