EFFECTIVENESS OF PROBLEM-BASED LEARNING MODEL ON MATERIAL FLAT SIDE GEOMETRY OF STUDENTS’ LEARNING OUTCOMES OF CLASS VIII MTS AN-NUR PALANGKA RAYA

This study aimed to determine the effectiveness of problem-based learning model on ??the material of flat side geometry on the learning outcomes of Class VIII students of MTs An-Nur Palangka Raya.This type of research is quantitative with quasi-experimental methods and one-group pre-test-post-test research design. The population in this study were all students of class VIII MTs An-Nur Palangka Raya of 77 people. From this population, random cluster sampling was chosen. Therefore 26 students of Class VIII-C were selected as the experimental class. The instruments of the data collection in this study were pre-test and post-test. The hypothesis of this study was tested using one-sample t-test. The results of the study indicate an average pretest ( )  of 23.61 and an average posttest ( )  of 46.30 and the average difference ( )   is 22.69. Before analyzing the data, the normality of  data is tested first. The normality test indicates = 2.168 and = 9,488. Because  <  and   follows the normal distribution. The results of the t test show the value of tcount = 1.92 and ttable = 1.708 at degrees of freedom (db) = n - 1 = 25 and the error level ? = 5% is obtained. Because tcount > ttable, then H0 is rejected and  is accepted. Therefore, it can be concluded that the PBL model is effective in improving students’ learning outcomes in the material of flat side geometry in class VIII MTs An-Nur Palangka Raya

Efektivitas Model Pembelajaran Berbasis Masalah (Problem Based Learning) pada Materi Bangun Ruang Sisi Datar terhadap Hasil Belajar

Tujuan Penelitian ini adalah untuk mengetahui efektifitas modelpembelajaran berbasis masalah (Problem Based Learning) pada materibangun ruang sisi datar terhadap hasil belajar siswa kelas VIII MTs An-NurPalangka Raya.Jenis Penelitian ini adalah kuantitatif dengan metode eksperimensemu dan desain penelitian one-group pretest-posttest design. Populasi padapenelitian ini adalah seluruh siswa kelas VIII MTs An-Nur Palangka Rayaberjumlah 77 orang. Dari populasi tersebut dipilih secara cluster randomsampling, sehingga terpilih kelas VIII-C sebanyak 26 orang sebagai kelaseksperimen. Instrumen dalam penelitian ini adalah soal pretest dan posttest. Hipotesis penelitian ini diuji menggunakan uji t satu pihak. Berdasarkan hasil penelitian diperoleh rata-rata pretest ( ) = 23,61dan rata-rata posttest ( ) = 46,30 serta rata-rata selisih ( ) = 22,69.Sebelum analisis data tersebut dilakukan terlebih dahulu uji kenormalan data. Dari uji normalitas diperoleh =2,168 dan =9,488, olehkarena maka mengikuti distribusi normal.Berdasarkan hasil uji t diperoleh nilai = 1,92 dan = 1,708 padaderajat kebebasan (db) = n - 1 = 25 dan taraf kesalahan = 5%. Olehkarena maka ditolak dan diterima. Sehingga dapatdisimpulkan model PBM efektif untuk meningkatkan hasil belajar siswamateri bangun ruang sisi datar kelas VIII MTs An-Nur Palangka Raya
