Abstract

Penelitian ini bertujuan untuk meneliti pengaruh Problem Based Learning terhadap kemampuan literasi matematis siswa. Penelitian ini merupakan penelitian eksperimen. Desain penelitian ini menggunakan post-test-only control design. Populasi dalam penelitian ini adalah seluruh siswa kelas VIII di SMPS Kopisan Singkawang. Pengambilan sampel dalam penelitian ini menggunakan cluster random sampling dan diperoleh kelas VIII B sebagai kelas eksperimen dan kelas VIII A sebagai kelas kontrol. Adapun untuk memperoleh data menggunakan tes kemampuan literasi matematis dalam bentuk soal uraian. Hasil tes kemampuan literasi matematis pada kelas eksperimen diperoleh nilai rata-rata 8,444 dan pada kelas kontrol diperoleh nilai rata-rata 6,933. Setelah dilakukan pengujian hipotesis menggunakan uji independent diperoleh ???? ℎ???????????????????? = 3,4964 > ???????????????????????? = 2,03951  pada taraf signifikan 5%,  artinya terdapat perbedaan yang signifikan antara kelas kontrol dan kelas eksperimen. Kemudian diperoleh Effect Size sebesar 0,88 dengan interpretasi kategori besar. Oleh karena itu, dapat disimpulkan bahwa model pembelajaran Problem Based Learning berpengaruh terhadap kemampuan literasi matematis siswa kelas VIII di SMPS Kopisan Singkawang

Abstract

The problem of learning mathematics at SD 06 satai c class v shows that learning outcomes are still low, this research aims to 1) To determine the increase in learning outcomes using heuristic learning strategies in class V of SD Negeri 06 Satai C. 2) To see the results of mathematics learning reaching the KKM individually by implementing heuristic learning strategies in class V of SD Negeri 06 Satai C. 3) To find out whether student learning activities are classified as good in debit material when heuristic learning strategies are applied. The research used was a quasi experimental design research with a one group pretest-posttest design. The population of this study was class V students at SD Negeri 06 Satai C. The sample was class V with a total of 24 students. N-Gain test to see improvements in student mathematics learning outcomes. The result is N-Gain = 0,318 with medium criteria in the range 0,3 ≤ N – gain < 0,7. The results show that there is an increase. Next, use the one sample t-test formula. The normality test results showed that  was 6,355 and  was 7,814. Because  ≤   is 6,355 ≤ 7,814, it is normally distributed, so it is known that = 5,915 and  = 2,010, we get    = 5,915  2,010 then Ha is accepted and Ho is rejected. So it can be concluded that individual students' mathematics learning outcomes reach the KKM. Next, to find out students' learning activities, use an observation sheet. From the data, the percentage of student learning activities is 85%. This shows that students' learning activities during learning are in the very active category and are classified as good.
