Abstract

Penelitian ini bertujuan menganalisis perbedaan peningkatan pemahaman konsep fisika antara siswa yang belajar dengan model pembelajaran Problem Solving (PS) dan siswa yang belajar dengan model pembelajaran Direct Instruction (DI). Masalah pada penelitian ini adalah pemahaman konsep siswa rendah. Penelitian ini merupakan penelitian eksperimen semu (quasi exsperiment) dengan rancangan non-equivalent pretest-posttest control group design. Populasi penelitian ini adalah siswa kelas X MAN Patas Tahun Pelajaran 2015/2016. Populasi sampel penelitian terdiri dari 2 kelas dengan jumlah siswa sebanyak 64 yang ditentukan secara simple random sampling. Data pemahaman konsep fisika dikumpulkan menggunakan 26 butir tes pemahaman konsep. Data dianalisis secara deskriptif dan statistik ANAVA satu jalur. Analisis dilanjutkan dengan uji Least Significant Difference (LSD) untuk menguji pasangan skor rata-rata tiap kelompok perlakuan. Pengujian hipotesis nol dilakukan pada taraf signifikansi 0,05. Semua analisis dilakukan dengan memanfaatkan software SPSS 16.0 for Windows. Hasil penelitian menunjukkan temuan-temuan yaitu. (1) Secara deskriptif kelompok PS lebih unggul dibandingkan dengan kelompok DI. (2) terdapat perbedaan yang signifikan pemahaman konsep fisika siswa yang belajar dengan model pembelajaran problem solving dan model pembelajaran DI (F = 79,008; p<0,05). Pemahaman konsep fisika siswa yang belajar dengan menggunakan PS dan DI berada pada kualifikasi cukup (M = 70,55; SD = 2,45) dan (M = 44,83; SD =2, 64). (3) Uji lanjut menunjukkan bahwa terdapat pengaruh pemahaman konsep fisika siswa yang belajar dengan model pembelajaran PS lebih baik dibandingkan dengan model pembelajaran DI

This research aimed at analyzing the differences enhancement of physics conceptual understanding between the students who were taught by using Problem Solving learning model and the students who were taught by using Direct Instruction learning model. The problems in this research was the low of the students concept understanding. The researh was a quasi-experimental research with non-equivalent pretest-posttest control group design. The population of this researh was the first grade students of MAN Patas in academic year 2015/2016. The sample of population consisted of two classes with selecting 64 students as sample by using a simple random sampling. Data were collected by using a 26 items of a physics concept understanding test. Data were analyzed descriptively with using one way ANAVA statistics. Least Significant Difference was used for further analysis to test the average score couple of each treatment group. The null hypothesis test was performed at the significance level 0.05. All analyzes were done by using SPSS 16.0 for Windows. The results show that (1) Descriptively, the PS group is superior than the DI group. (2) there is a significant difference of physics concept understanding between the students who learn by using problem solving and the students who learn by using DI model (F = 79.008, p <0.05). The student’s conceptual understanding who learn by using PS and DI are at the qualification “fair” (M = 70.55; SD, = 2.45) and (M = 44.83; SD = 2, 64). (3). Advanced test shows that the influence of physics concept understanding of students who learn by using PS model is better than the students who learn by using DI model.
