Abstract: Mathematics learning outcomes among Grade IX students at SMPN 3 Kempas remain relatively low, indicating the need for a learning model that can support better learning outcomes. This study aimed to determine whether the mathematics learning outcomes of students taught using the Problem-Based Learning (PBL) model were better than those of students taught using conventional instruction on the topic of Systems of Linear Equations in Two Variables (SPLDV). This study employed a quantitative approach with a quasi-experimental method and a Nonequivalent Posttest-Only Control Group Design. The sample consisted of Class IX.A as the experimental group and Class IX.D as the control group, selected using the simple random sampling technique. Data were collected through a written mathematics achievement test consisting of essay questions. The results showed that the average posttest score of the experimental group was 71.13, while that of the control group was 54.78. The normality test yielded p-values of 0.203 for the experimental group and 0.112 for the control group. Meanwhile, the homogeneity of variance test yielded a p-value of 0.680. Since all p-values were greater than 0.05, the data met the assumptions of normality and homogeneity of variance. The t-test yielded a p-value of less than 0.001; therefore, the null hypothesis was rejected. Thus, the mathematics learning outcomes of students taught using the PBL model were better than those of students taught using conventional instruction on the topic of SPLDV in Grade IX at SMPN 3 Kempas.
Keywords: learning outcomes; problem based learning; conventional learning; systems of linear equations in two variables.
Abstrak: Hasil belajar matematika peserta didik kelas IX SMPN 3 Kempas masih tergolong rendah, sehingga diperlukan model pembelajaran yang dapat mendukung pencapaian hasil belajar yang lebih baik. Penelitian ini bertujuan untuk mengetahui apakah hasil belajar matematika peserta didik yang belajar menggunakan model Problem Based Learning (PBL) lebih baik daripada peserta didik yang belajar menggunakan pembelajaran konvensional pada materi Sistem Persamaan Linear Dua Variabel (SPLDV). Penelitian ini menggunakan pendekatan kuantitatif dengan metode eksperimen semu (quasi experiment) dan rancangan Nonequivalent Posttest-Only Control Group Design. Sampel penelitian terdiri atas kelas IX.A sebagai kelas eksperimen dan kelas IX.D sebagai kelas kontrol yang dipilih menggunakan teknik simple random sampling. Data dikumpulkan melalui tes akhir hasil belajar matematika berbentuk uraian. Hasil analisis menunjukkan bahwa rata-rata nilai tes akhir kelas eksperimen sebesar 71,13, sedangkan kelas kontrol sebesar 54,78. Hasil uji normalitas menunjukkan nilai p-value sebesar 0,203 pada kelas eksperimen dan 0,112 pada kelas kontrol. Sementara itu, uji homogenitas variansi menghasilkan p-value sebesar 0,680. Karena seluruh nilai p-value lebih besar dari 0,05, data memenuhi kriteria pengujian normalitas dan homogenitas variansi. Hasil uji-t menunjukkan p-value kurang dari 0,001, sehingga ditolak. Dengan demikian, hasil belajar matematika peserta didik yang belajar menggunakan model PBL lebih baik daripada peserta didik yang belajar menggunakan pembelajaran konvensional pada materi SPLDV di kelas IX SMPN 3 Kempas.
Kata kunci: hasil belajar; problem based learning; pembelajaran konvensional; sistem persamaan linear dua variabel.
