KOMPARASI PENINGKATAN PEMAHAMAN KONSEP DAN SIKAP ILMIAH SISWA SMA YANG DIBELAJARKAN DENGAN MODEL PEMBELAJARAN PROBLEM BASED LEARNING DAN PROJECT BASED LEARNING

Abstract

Penelitian ini bertujuan untuk : (1). mengetahui dan menganalisis perbedaan peningkatan pemahaman konsep kimia dan sikap ilmiah siswa yang dibelajarkan dengan model pembelajaran Problem Based Learning dengan siswa yang dibelajarkan dengan model pembelajaran Project Based Learning, (2). untuk mengetahui dan menganalisis perbedaan peningkatan pemahaman konsep kimia antara siswa yang dibelajarkan dengan model pembelajaran Problem Based Learning dengan siswa yang dibelajarkan dengan model pembelajaran Project Based Learning, (3) untuk mengetahui dan menganalisis perbedaan peningkatan sikap ilmiah antara siswa yang dibelajarkan dengan model pembelajaran Problem Based Learning dengan siswa yang dibelajarkan dengan model pembelajaran Project Based Learning. Penelitian ini merupakan penelitian eksperimen semu dengan rancangan pretest-postest non-equivalen control group design. Populasi dari penelitian ini adalah siswa kelas XI IPA SMA Negeri 1 Susut tahun pelajaran 2014/2015. Sedangkan sampel dari penelitian ini adalah siswa kelas XI IPA1 dan XI IPA 3 yang ditentukan dengan teknik simple random sampling terhadap kelas yang sudah disetarakan. Sampel yang terpilih adalah kelas XI IPA1 sebagai kelompok eksperimen yang dikenai perlakuan dibelajarkan dengan model pembelajaran Problem Based Learning (PBL) dan kelas XI IPA 3 sebagai kelompok ekperimen yang dikenai perlakuan dibelajarkan dengan model pembelajaran Project Based Learning (PjBL). Data dikumpulkan dengan menggunakan tes pemahaman konsep dan kuisioner sikap ilmiah. Data dianalisis dengan statistik deskriptif dan inferensial menggunakan multivariate analysis of variance (MANOVA). Hasil penelitian menunjukkan bahwa (1) peningkatan pemahaman konsep kimia dan sikap ilmiah siswa yang dibelajarkan dengan model pembelajaran Project Based Learning (PjBL) lebih tinggi dibandingkan dengan siswa yang dibelajarkan dengan Problem Based Learning (PBL); (2) peningkatan pemahaman konsep kimia siswa yang dibelajarkan dengan model pembelajaran Project Based Learning (PjBL) lebih tinggi dibandingkan dengan siswa yang dibelajarkan dengan model pembelajaran Problem Based Learning (PBL); (3) peningkatan sikap ilmiah siswa yang dibelajarkan dengan model pembelajaran Project Based Learning PjBL lebih baik dibandingkan dengan siswa dibelajarkan Problem Based Learning (PBL)

This research aims at: (1) finding out and analyzing differences in improvement of chemical concept understanding and scientific attitude between students which were taught by problem based learning and those taught by using project based learning, (2) finding out and analyzing differences in improvement of chemical concept understanding between students which were taught by problem based learning and those taught by using project based learning, (3) finding out and analyzing differences in improvement of scientific attitude between students which were taught by problem based learning and those taught by using project based learning. This study is pseudo experimental research with pretest-postest non equivalent control group design. The population of this study is eleventh grade students in SMA Negeri 1 Susut in academic year 2014/2015, then XI IPA 1 and XI IPA 3 were selected as sample of the study through simple random sampling technique. XI IPA 1 was an experimental group which treated by using problem based learning and XI IPA 3 was also an experimental group which treated by using project based learning. Data were collected by chemical concept understanding test and questionnaire of scientific attitude, which then analyzed by inferential and descriptive statistics using multivariate analysis of variance (MANOVA). The research discovers: (1) the improvement of chemical concept understanding and scientific attitude between students who were taught by project based learning (PjBL) is higher than those treated by problem based learning (PBL), (2) the improvement of chemical concept understanding between students who were taught by project based learning (PjBL) is higher than those treated by problem based learning (PBL), (3) the improvement of scientific attitude between students who were taught by project based learning (PjBL) is better than those treated by problem based learning (PBL)
