PENERAPAN MODEL PEMBELAJARAN BERBASIS PROYEK UNTUK MENINGKATKAN KETERAMPILAN PROSES SAINS SISWA PADA KONSEP PENCEMARAN LINGKUNGAN DI SMP
ABSTRACT: The purpose of this
study is to improve science processing skills of students of SMPN 8 Banda Aceh
in the concept of pollution and environmental degradation by using
project-based learning. An experimental method with pretest-posttest control
group design was used in this study. The population was all students of class
VII SMPN 8 Banda Aceh which consisted of 5 classes with total number was 130
students. The samples were selected by using simple random sampling technique.
There were 44 students from VII-1 acted as control group and class VII-2 acted
as experimental group. The data were gathered by using pre-test and post-test.
The research instruments used were essay questions to measure science
processing skills, student’s work sheet, and work assessment’s rubrics based on
science processing skills. The data then analyzed by calculating the post-test
and pre-test gain and t-test to compare between the experimental class and
control class. They were analyzed by using independent sample t-test. The
results showed that there were improvement in the average of science processing
skills of students in project-based learning’s class for about 51.86 (high) and
conventional learning class for about 38.02 (medium). T-test results obtained
as follows: tvalue was 2.680 and ttable was 2.021, so tvalue>ttable. The
conclusion was the implementation of project-based learning in the concept of
pollution and environmental degradation improved the science processing skills
of student of SMPN 8 Banda Aceh.
