KOMPARASI PENINGKATAN KETERAMPILAN BERPIKIR KRITIS DAN KINERJA ILMIAH SISWA YANG DIBELAJARKAN DENGAN MODEL PROJECT BASED LEARNING DAN MODEL PEMBELAJARAN INKUIRI TERBIMBING
Abstract
Penelitian ini bertujuan mendeskripsikan dan menganalisis perbedaan: (1) peningkatan keterampilan berpikir kritis dan kinerja ilmiah antara siswa yang dibelajarkan dengan model project based learning (PjBL) dan siswa yang dibelajarkan dengan model pembelajaran inkuiri terbimbing, (2) peningkatan keterampilan berpikir kritis antara siswa yang dibelajarkan dengan model PjBL dan siswa yang dibelajarkan dengan model pembelajaran inkuiri terbimbing, (3) peningkatan kinerja ilmiah antara siswa yang dibelajarkan dengan model PjBL dan siswa yang dibelajarkan dengan model pembelajaran inkuiri terbimbing. Populasi penelitian eksperimen semu berdesain pretest-posttest non-equivalent control group design ini adalah siswa kelas X SMAN 2 Bangli tahun pelajaran 2014/2015 yang berjumlah 148 orang dan terbagi menjadi lima rombongan belajar. Sampel penelitian ditentukan dengan teknik simple random sampling terhadap kelas yang sudah disetarakan. Sampel yang terpilih adalah siswa kelas XA dan XD sebagai kelompok eksperimen yang dibelajarkan dengan model PjBL dan siswa kelas XB dan XC sebagai kelompok kontrol yang dibelajarkan dengan model pembelajaran inkuiri terbimbing. Data dikumpulkan dengan tes keterampilan berpikir kritis dan tes kinerja ilmiah. Data dianalisis dengan statistik deskriptif dan inferensial menggunakan multivariate analysis of variance (MANOVA). Hasil penelitian menunjukkan bahwa: (1) keterampilan berpikir kritis dan kinerja ilmiah siswa yang dibelajarkan dengan model PjBL lebih tinggi daripada siswa yang dibelajarkan dengan model pembelajaran inkuiri terbimbing; (2) keterampilan berpikir kritis siswa yang dibelajarkan dengan model PjBL lebih tinggi daripada siswa yang dibelajarkan dengan model pembelajaran inkuiri terbimbing; (3) kinerja ilmiah siswa yang dibelajarkan dengan model PjBL lebih tinggi daripada siswa yang dibelajarkan dengan model pembelajaran inkuiri terbimbing.

This research was aimed to describe and analyze the differences of: (1) improvement of critical thinking skill and scientific performance between students taught by project based learning (PjBL) model and those taught by using guided inquiry one, (2) improvement of critical thinking skill between students taught by PjBL model and those taught by using guided inquiry one, (3) improvement of scientific performance between students taught by PjBL model and those taught by using guided inquiry one. The population in this experimental quasi research with this pretest-posttest non-equivalent control group design is the tenth grade students in SMAN 2 Bangli in academic year 2014/2015. There are 148 students which divided into five classes. The sample was determined by simple random sampling, then the XA and XD classes became experimental group which were treated by PjBL model and XB and XC classes become the control group which were treated by guided inquiry one. The data was collected by critical thinking skill and scientific performance tests, which then analyzed by inferential and descriptive statistics using multivariate analysis of variance (MANOVA). The research discovers: (1) students’ critical thinking skill and scientific performance taught by PjBL model is higher than those taught by using guided inquiry one; (2) students’ critical thinking skill taught by PjBL model is higher than those taught by using guided inquiry one; (3) students’ scientific performance taught by PjBL model is higher than those taught by using guided inquiry one.
