Pengaruh Model Pembelajaran Berbasis Proyek dan Kooperatif Tipe Group Investigation (GI) terhadap Penguasaan Konsep Siswa di SMA pada Materi Sistem Pernapasan
Abstract: This research aimed
to investigate the effect of using project based learning (PjBL) toward
student’s concept learning of exact eleven grade senior high school students in
respiratory system. The design of the study was quasi-experimental research
design with pre-test and post-test control group design. The population of this
research was all students in exact eleven grade of SMA Medan Academic Year
2014/2015 which consist of 11 classes. Taking sample done by using purposive
sampling technique and the classes chosen are three classes i.e. XI MIA 10 (PjBL),
XI MIA 7 (GI) and XI MIA 5 (Conventional). Research instrument are multiple
choices (C1-C6) for collecting the student’s concept mastery aspect. The
statistical assumption test revealed that the data were normally distributed
and homogent. Hypothesis analysed using Analysis of Covariant (ANACOVA) followed
by Tukey’s test assisted by SPSS 19.00. Research result showed that learning
models effect the student’s concept mastery significantly. Student’s concept
mastery was 80,05± 4, 23 for project-based learning class, and it differs
significantly towards group investigation class (73,75 ± 5,95) (P=0,000), and
conventional class (70,77±5,56) (P=0,000). Group investigation also differs
significantly towards conventional learning (P=0,023). The result showed that
student’s concept mastery on project-based learning class was higher than group
investigation and conventional learning class.
