Abstract

Penelitian ini bertujuan untuk mengetahui apakah model pembelajaran kooperatif tipe Teams Games Tournament (TGT) berbantuan Wordwall memiliki pengaruh terhadap kemampuan pemecahan masalah matematis siswa SMP Negeri 8 Jakarta. Metode yang digunakan dalam penelitian ini adalah quasi experiment dengan desain posttest-only control group. Sampel dalam penelitian ini dipilih menggunakan teknik cluster random sampling, diperoleh 36 siswa dari kelas VIII-D sebagai kelas eksperimen dan 35 siswa dari kelas VIII-C sebagai kelas kontrol. Kemampuan pemecahan masalah matematis siswa diukur melalui lima soal uraian pada materi peluang yang digunakan sebagai instrumen penelitian yang telah dinyatakan valid dan reliabel. Berdasarkan uji prasyarat analisis data, kedua kelas tersebut memiliki distribusi normal dan varians yang relatif homogen sehingga pengujian hipotesis menggunakan uji-t pada taraf signifikansi (α) = 0,05. Hasil perhitungan uji-t menunjukkan t_hitung>t_((1-α;n_1+n_2-2)) yaitu 3,452>1,667 dan p-value<α yaitu 0,001<0,05 yang berarti sudah cukup bukti untuk menolak H_0. Dengan demikian, rata-rata kemampuan pemecahan masalah matematis siswa kelas eksperimen lebih tinggi daripada siswa kelas kontrol. Oleh karena itu, dapat dinyatakan bahwa model pembelajaran kooperatif tipe TGT berbantuan Wordwall terindikasi memberikan pengaruh terhadap kemampuan pemecahan masalah matematis siswa. Nilai besar pengaruh dihitung melalui uji Cohen’s, diperoleh nilai sebesar 0,82 yang merepresentasikan tingkat pengaruh besar yaitu 79%. Kata Kunci: model pembelajaran kooperatif tipe TGT, Wordwall, kemampuan pemecahan masalah matematis, peluang ***** This study aims to determine whether the cooperative learning model of the Teams Games Tournament (TGT) type assisted by Wordwall has an effect on the mathematical problem-solving ability of students at SMP Negeri 8 Jakarta. The method used in this research is a quasi-experiment with a posttest-only control group design. The sample in this study was selected using the cluster random sampling technique, resulting in 36 students from class VIII-D as the experimental group and 35 students from class VIII-C as the control group. Students' mathematical problem-solving abilities were measured using five essay questions on the topic of probability, which served as research instruments that had been validated and declared reliable. Based on the data analysis equipment test, both classes have a normal distribution and relatively homogeneous variance so that the hypothesis testing uses a t-test at a significance level (α) = 0.05. The results of the t-test calculation show that t_value>t_((1-α;n_1+n_2-2)), namely 3.452 > 1.667, and a p-value < α, namely 0.001 < 0.05, indicating sufficient evidence to reject H_0. Thus, the average mathematical problem-solving ability of students in the experimental class is higher than that of students in the control class. Therefore, it can be concluded that the TGT cooperative learning model assisted by Wordwall has a significant effect on students' mathematical problem-solving abilities. The magnitude of the effect was calculated using Cohen’s effect size, yielding a value of 0.82, which represents a large effect size, equivalent to 79%. Keywords: TGT-type cooperative learning model, Wordwall, mathematical problem-solving ability, probability
