IMPLEMENTASI PEMBELAJARAN KIMIA BERBASIS LINGKUNGAN DENGAN MODEL PROBLEM BASED LEARNING (PBL) UNTUK MENINGKATKATKAN MINAT DAN KETERAMPILAN BERPIKIR KRITIS PADA SISWA SMA
Journal Title: Lantanida Journal - Year 2015, Vol 3, Issue 2
Abstract
This study aims to analyze: (1) the difference between the critical thinking skills that students learn through the implementation model of Problem Based Learning (PBL) environment based on petroleum materials with students who learn through conventional learning model (2) differences in student interest through implementation model (PBL) environment based on the students' interest through conventional learning models. This study was a quasi-experimental research in class X of SMA KARTIKA XIV-1 BANDA ACEH in Academic Year 2013/2014. The research design was a two-group pretest-posttest design. Data were analyzed by independent t-test statistical analysis test with the software program SPSS version 17. The results obtained by analysis of the percentage of the average value of the initial test experimental class is 25.00 and 24.69 for the control class. Furthermore, the percentage of the average value of the final test in the experimental class at 77.35, while the control class is 62.19. The average N-gain normalized experimental class were high with an average rating of 0.75 while the control class including medium category with an average rating of 0.50. For N-normalized gain obtained t = 6.045 with signfikansi p = 0.000, due to the significance <0.05, it can be said that the increase in petroleum mastery of concepts in students who get learning with learning model (PBL) environment based on better than the mastery petroleum concepts in students who received conventional learning model. The results of the N-gain critical thinking skills obtained t = 3.44 with p = 0.002 signfikansi, because the significance <0.05, it can be said that the increase in critical thinking skills in students who get learning with learning model (PBL) environment based on better than with students who received conventional learning model. The results obtained charging student questionnaire that by using a model of learning (PBL) environment based on the concept of petroleum given to 22 students gave positive responses and students have high interest to follow the learning.
