ABSTRAK Skripsi ini atas nama Reski Rahma Desvita NIM 2421068 yang berjudul ”Peningkatan Keaktifan Belajar Matematika Siswa Kelas X SMA N 1 Lembah Gumanti Melalui Penerapan Model Pembelajaran Interactive Conceptual Instruction (ICI)” Penelitian ini dilatar belakangi berdasarkan hasil observasi dan wawancara di SMA N 1 Lembah Gumanti dimana rendahnya keaktifan belajar matematika siswa dan pembelajaran yang berpusat pada guru, serta model yang diterapkan belum bervariasi. Salah satu cara yang dapat dilakukan untuk mengatasi permasalahan tersebut adalah dengan menggunakan model pembelajaran Interactive Conceptual Instruction (ICI) . Tujuan penelitian ini adalah untuk melihat apakah keaktifan belajar matematika siswa dengan menggunakan model pembelajaran Interactive Conceptual Instruction lebih baik dari pembelajaran konvensional pada kelas X SMA N 1 Lembah Gumanti. Jenis penelitian ini adalah pra-eksperimen dengan rancangan penelitian One Group Pretest-Posttest. Populasi pada penelitian ini adalah seluruh siswa kelas X SMA N 1 Lembah Gumanti yang berjumlah 9 kelas. Pengambilan sampel ditentukan secara Purposive Smapling. Dengan alasan, setelah konfirmasi dengan guru mata pelajaran matematika direkomendasikan untuk memilik kelas X E6 karena siswa yang kurang aktif dan sedang mempelajari materi eksponensial. Sampel pada penelitian ini adalah siswa kelas X E6. Instrument yang digunakan adalah angket Pretestposttest. Data diolah menggunakan analisis statistik uji-t. Berdasarkan hasil analisis data pretest- posttest matematika siswa t_hitung=9,8475 dan t_(tabel )=1,67 . karena t_hitung>t_tabel=artinya tolak H_0 dan terima H_1. Data diolah menggunakan software SPSS diperoleh P_( value)=0,377 dan α=0,05 sehingga P_( value)>α . Jadi, dapat disimpulkan bahwa terdapat Peningkatan Keaktifan Belajar Matematika Siswa Kelas X SMA N 1 Lembah Gumanti Melalui Penerapan Model Pembelajaran Interactive Conceptual Instruction (ICI). Kata Kunci : Keaktifan Belajar Matematika , Model Pembelajaran Interactive Conceptual Instruction (ICI) ABSTRACT This thesis is submitted by Reski Rahma Desvita (Student ID 2421068) and is titled "Improving Mathematics Learning Engagement Among Grade X Students at SMA N 1 Lembah Gumanti Through the Implementation of the Interactive Conceptual Instruction (ICI) Learning Model." This research was motivated by observations and interviews at SMA N 1 Lembah Gumanti, which revealed low student engagement in mathematics learning, a teacher-centered instructional approach, and a lack of variety in the teaching models used. One strategy to address these issues is the implementation of the Interactive Conceptual Instruction (ICI) learning model. The objective of this study was to determine whether mathematics learning engagement among Grade X students at SMA N 1 Lembah Gumanti improved when using the ICI model compared to conventional instruction. This study employed a pre-experimental design, specifically the One-Group Pretest-Posttest design. The population consisted of all Grade X students at SMA N 1 Lembah Gumanti, distributed across nine classes. Purposive sampling was used to select the participants; following consultation with the mathematics teacher, class X E6 was selected because the students exhibited low engagement and were currently studying the topic of exponents. The sample for this study was the students of class X E6. Data collection utilized pretest and posttest questionnaires, and the data were analyzed using a t-test. Based on the analysis of the mathematics pretest and posttest data, the calculated t-value ($t_{count}$) was 9.8475, while the critical t-value ($t_{table}$) was 1.67. Since $t_{count} > t_{table}$, the null hypothesis ($H_0$) was rejected, and the alternative hypothesis ($H_1$) was accepted. Data processing using SPSS software yielded a p-value of 0.377; given that the significance level ($\alpha$) was 0.05, the p-value was greater than $\alpha$ ($p > \alpha$). Thus, it can be concluded that the implementation of the Interactive Conceptual Instruction (ICI) learning model led to an improvement in mathematics learning engagement among Grade X students at SMA N 1 Lembah Gumanti.
