Efektivitas Model Pembelajaran Two Stay Two Stray dan Think Pair Share Ditinjau dari Kemampuan Pemecahan Masalah Matematika Siswa Kelas 5 SD

Abstract

Kegiatan penelitian ini dilakukan guna mengetahui efektivitas model Two Stay Two Stray dan model pembelajaran Think Pair Share guna meningkatkan kemampuan pemecahan masalah matematika siswa kelas 5 SD. Jenis penelitian yang dijadikan sebagai acuan pada kegiatan penelitian ini ialah penelitian Quasi Eksperimental dengan desain Nonequivalent Control Group. Sebanyak 250 peserta didik kelas 5 SD pada Gugus Gajah Mada, Kota Salatiga dijadikan sebagai populasi dalam kegiatan penelitian ini. Namun hanya 78 peserta didik dari SD Negeri Dukuh 01, SD Negeri Dukuh 03, dan SD Negeri Kecandran 1 yang digunakan sebagai sampel penelitian. Hasil pengolahan data menggunakan uji T-test menunjukkan nilai Sig. (2-tailed) sebesar 0,004 < 0,05 maka Ho ditolak dan Ha diterima, sehingga terdapat perbedaan nilai signifikansi dari kedua model tersebut. Hasil tersebut juga di dukung dengan perbedaan hasil kenaikan nilai rerata kelas pada kelompok eksperimen 1 sebesar 24,18 sedangkan pada eksperimen 2 sebesar 18. Berdasarkan hasil tersebut dapat disimpulkan bahwa kemampuan pemecahan masalah matematika siswa kelas 5 SD menggunakan model pembelajaran Two Stay Two Stray memiliki tingkat efektivitas lebih tinggi dibandingkan dengan model pembelajaran Think Pair Share.

This research activity was carried out to determine the effectiveness of the Two Stay Two Stray model and the Think Pair Share learning model in improving the mathematical problem solving abilities of grade 5 elementary school students. The type of research used as a reference for this research activity is Quasi Experimental research with a Nonequivalent Control Group design. A total of 250 5th grade elementary school students in the Gajah Mada Cluster, Salatiga City were used as the population for this research activity. However, only 78 students from SD Negeri Dukuh 01, SD Negeri Dukuh 03, and SD Negeri Kecandran 1 were used as research samples. The results of data processing using the T-test show a Sig value. (2-tailed) is 0.004 < 0.05, so Ho is rejected and Ha is accepted, so there is a difference in the significance value of the two models. These results are also supported by the difference in the results of the increase in the class average score in experimental group 1 which was 24.18 while in experiment 2 it was 18. Based on these results it can be concluded that the mathematical problem solving abilities of 5th grade elementary school students using the Two Stay Two Stray learning model have a level of Greater effectiveness compared to the Think Pair Share learning model. Based on these results, it can be concluded that the mathematics problem solving abilities of 5th grade elementary school students using the Two Stay Two Stray learning model have a higher level of effectiveness compared to the Think Pair Share learning model.
