PENGARUH MODEL PEMBELAJARAN KOOPERATIF TIPE GI (GROUP INVESTIGATION) BERBANTUAN MULTIMEDIA INTERAKTIF TERHADAP HASIL BELAJAR IPA

Abstract

Permasalahan yang dihadapi dalam penelitian ini adalah rendahnya perolehan hasil belajar siswa pada mata pelajaran IPA, siswa tidak aktif dalam pembelajaran, pembelajaran yang tidak melibatkan siswa, kurangnya media dalam proses pembelajaran dan siswa cepat mengalami kebosanan. Penelitian ini membahas tentang (1) Bagaimanakah hasil belajar IPA siswa yang mengikuti model pembelajaran konvensional tanpa berbantuan multimedia interaktif, (2) Bagaimanakah hasil belajar IPA siswa yang mengikuti model pembelajaran kooperatif tipe GI (Group Investigation) berbantuan multimedia interaktif, (3) Apakah terdapat perbedaan yang signifikan terhadap hasil belajar IPA antara siswa yang mengikuti model pembelajaran kooperatif tipe GI (Group Investigation) berbantuan multimedia interaktif dengan siswa yang mengikuti model pembelajaran konvesional tanpa berbantuan multimedia interaktif di kelas VII SMPN 3 Sawan. Jenis penelitian ini adalah penelitian eksperimen semu dengan rancangan posttes-control group design. Populasi dalam penelitian ini adalah seluruh siswa kelas VII SMPN 3 Sawan tahun pelajaran 2014/2015 yang berjumlah 208 siswa terdiri dari 8 kelas. Sampel diambil dengan teknik random sampling, yang terpilih menjadi kelas eksperimen adalah kelas VII A3 sebanyak 27 siswa dan yang terpilih menjadi kelas kontrol adalah kelas VIIA5 sebanyak 25 siswa. Data dikumpulkan dengan metode tes dengan tes hasil belajar. Data yang diperoleh dianalisis dengan teknik analisis statistik deskriptif kuantitatif. Berdasarkan hasil analisis data deskriptif menunjukkan bahwa rata-rata skor hasil belajar IPA kelas eksperimen adalah 25,00 sedangkan kelas kontrol 20,60. Di dalam analisis data hasil uji-t menunjukkan thitung = 6,141 sedangkan ttabel = 2,021. Jadi thitung > ttabel sehingga hasil penelitian ini adalah signifikan. Hal ini menunjukkan bahwa terdapat perbedaan yang signifikan hasil belajar IPA antara kelompok siswa yang dibelajarkan dengan model pembelajaran kooperatif tipe GI (Group Investigation) berbantuan multimedia interaktif dan kelompok siswa yang dibelajarkan dengan pembelajaran konvensional.

The problems that faced in this research was decreasing of students’ learning result in Science subject matter, the students were not active in learning process, lack of method that involved the students learning process, lack of media and lack of motivation that made students feel bored. This research discussed about the differences which was valuable toward the result of students’ learning in science subject by using GI (Group Investigation) cooperative learning method which was combined with interactive multimedia. This method was used for students who used conventional learning method in 7th grade students in SMP N 3 Sawan academic year 2014/2015 which had some problems as follow: (1) how is the result of students’ learning that uses conventional method without interactive multimedia in science subject. (2) How is the result of students’ learning that uses GI (Group Investigation) cooperative learning method with interactive multimedia. (3) Is there any significant and differences between the result of students’ science learning that use conventional method without interactive multimedia and the result of students’ learning that uses GI (Group Investigation) cooperative learning method with interactive multimedia in 7th grade students in SMP N 3 Sawan academic year 2014/2015. This research was experiment research which designed by using posttest-control group design. The population of this research was all of 7th grade students in SMP N 3 Sawan which contained 208 students and 8 classes. Sample was obtained by using random sampling which was selected as follow: VII A3 was selected as an experiment group which was contained 27 students and VII A5 was selected as control group which was contained 25 students. The data was collected by using test and test result method. The data collections were analyzed by using descriptive-quantitative statistical analysis technique. Based on the result of data description, the average of students’ score in experiment class was 25.00 meanwhile control group class was 20.60. In data analysis, the result of T-experiment showed T-hitung = 6.141 while T-tabel = 2.021. So, T-hitung> T- table, T- hitung was bigger than T-table, it means there is a significant difference in this study. In conclusion, there is a significant difference between the result of students’ learning that uses GI (Group Investigation) cooperative learning method with interactive multimedia and the result of students’ learning that use conventional method without interactive multimedia in science subject.
