Abstract

Tujuan dari penelitian ini adalah untuk mengetahui apakah menggunakan model pembelajaran NHT efektif pada kemampuan pemecahan masalah matematika siswa dengan topik sistem persamaan linear dua variabel pada siswa kelas delapan SMP Negeri 9 Padangsidimpuan. Penelitian ini dilakukan dengan menerapkan metode eksperimen (one group pretest post test design) dengan 25 siswa sebagai sampel dan mereka diambil dengan menggunakan teknik simple random sampling dari 169 siswa. Observasi dan tes digunakan dalam mengumpulkan data. Berdasarkan analisis deskriptif, ditemukan: (a) rata-rata menggunakan model pembelajaran NHT adalah 3,83 (kategori sangat baik) dan (b) kemampuan pemecahan masalah matematika siswa dengan topik sistim persamaan linear dua variabel sebelum menggunakan model pembelajaran NHT adalah 50,88 (kategori sedang) dan setelah menggunakan model pembelajaran NHT adalah 79,76 (kategori sangat baik). Selanjutnya, berdasarkan statistik inferensial dengan menggunakan pair sample ttest, (SPSS versi 17), hasilnya menunjukkan nilai signifikan kurang dari 0,05 (0,000 <0,05). Artinya, model pembelajaran NHT efektif digunakan pada kemampuan pemecahan masalah matematis siswa pada topik sistem persamaan linear dua variabel pada siswa kelas VIII SMP Negeri 9 Padangsidimpuan.

Abstract

Tujuan dari penelitian ini adalah untuk menggambarkan efektivitas menggunakan pendekatan terbuka terhadap kemampuan komunikasi matematis siswa pada topik statistik pada siswa kelas sepuluh SMA Negeri 1 Sibabangun. Penelitian ini dilakukan dengan menerapkan metode eksperimen (one group pretest post test design) dengan sampel 34 siswa dan diambil dengan menggunakan teknik cluster random sampling dari 178 siswa. Observasi dan tes digunakan dalam mengumpulkan data. Berdasarkan analisis deskriptif, ditemukan: (a) rata-rata menggunakan pendekatan terbuka adalah 3,7 (kategori sangat baik) dan (b) rata-rata pencapaian statistik siswa sebelum menggunakan pendekatan terbuka adalah 56,98 (kategori adil) dan setelah menggunakan pendekatan terbuka adalah 80,33 (kategori sangat baik). Selanjutnya berdasarkan statistik inferensial dengan menggunakan pair sample ttes, (SPSS versi 22), hasilnya menunjukkan nilai signifikan kurang dari 0,05 (0,000 <0,05).

Abstract

The background of this research is Covid 19 pandemic that it made the learning online. This case is a problem because students are not able to master the topic that given by teachers especially in mathematics learning that need problem solving. George Polya had given a solution to overcome this problem in his book entitle “How to solve it”. The thinking will be described in this research by approach library research. The informants of the research are bapak Muhammad Syahril Harahap and ibu Rahmatika Elindra. They are the lectures of mathematics department of IPTS. The research result is 1) thinking of George Polya is an effort to look for an overcome from a difficulty to get a purpose that it is not able to achieved soon and 2) there are 4 steps of problem solving which included a) understand the problem, b) planning completion the problem, c) conducting completion the problem, and d) correction the result again . Based on the explanation above, it’s concluded thinking of George Polya can apply in learning mathematics in Covid 19 pandemic.
