PERBEDAAN KEMAMPUAN PEMECAHAN MASALAH MATEMATIKA SISWA MENGGUNAKAN MODEL PEMBELAJARAN NHT DAN TS

Abstrak

Penelitian ini bertujuan untuk mengetahui perbedaan kemampuan pemecahan masalah matematika siswa yang diajar dengan menggunakan model pembelajaran (NHT) dan Talking Stick di kelas VIII MTs Cendekia Medan. Metode penelitian menggunakan metode kuantiatif, dengan jenis quasi experiment design. Sampel yang digunakan kelas VIII-A dan VIII-B. Teknik pengambilan sampel yaitu total sampling. Instrument penelitian berbentuk tes uraian, analisis data menggunakan uji independent sampel t-test. Hasil penelitian ini menunjukkan bahwa (1) Hasil post test kemampuan pemecahan masalah matematika siswa dengan menggunakan model pembelajaran NHT dikategorikan baik, dengan nilai mean 80,31, standar deviasi 9,02, varians 81,36, nilai terkecil 60, nilai terbesar 92. (2) Hasil post-test kemampuan pemecahan masalah matematika siswa dengan menggunakan model pembelajaran Talking Stick dikategorikan cukup baik, dengan nilai mean 72,33, standar deviasi 11,72, varians 137,54, nilai terkecil 45, niai terbesar 90. (3) thitung > ttable dengan (3,076>2,002) menyatakan H0 ditolak dan Ha diterima.

ABSTRACT This study aims to determine differences in students' mathematical problem solving abilities taught using the learning model (NHT) and Talking Stick in class VIII MTs Cendekia Medan. The research method uses a quantitative method, with a quasi-experimental design type. The samples used were class VIII-A and VIII-B. The sampling technique is total sampling. The research instrument was in the form of a description test, data analysis using an independent sample t-test. The results of this study indicate that (1) the post-test results of students' mathematical problem solving abilities using the NHT learning model are categorized as good, with a mean value of 80.31, standard deviation of 9.02, variance of 81.36, smallest value of 60, largest value of 92. (2) The post-test results of students' mathematical problem solving abilities using the Talking Stick learning model were categorized as quite good, with a mean value of 72.33, a standard deviation of 11.72, a variance of 137.54, the smallest value 45, the largest value 90. (3) tcount > ttable with (3.076>2.002) stating that H0 is rejected and Ha is accepted.
