ABSTRAK
Tujuan penelitian ini adalah untuk mengetahui pengaruh pembelajaran kooperatif menggunakan model Jigsaw dan GI, kreativitas, sikap ilmiah belajar, serta interaksinya terhadap prestasi belajar.
Penelitian ini menggunakan metode eksperimen. Populasinya terdiri dari seluruh siswa kelas XII jurusan Teknik Komputer Jaringan dan Broadcasting SMK PGRI 6 Ngawi tahun pelajaran 2012-2013, terdiri atas 5 kelas. Sampel diambil dengan teknik cluster random sampling, terdiri 2 kelas yaitu XIITKJ1 menggunakan model JIGSAW dan XIIBRO1 menggunakan model GI. Data prestasi belajar kognitif dikumpulkan dengan metode tes, metode angket untuk sikap ilmiah, kreativitas belajar, prestasi belajar afektif. Analisis data yang digunakan adalah analisis variansi tiga jalan dengan desain faktorial 2x2x2.
Berdasarkan hasil analisis data, disimpulkan: 1) ada pengaruh penggunaan metode JIGSAW dan GI terhadap  prestasi belajar kognitif dan afektif siswa, 2) ada pengaruh kreativitas terhadap prestasi belajar kognitif dan afektif siswa, 3) tidak ada pengaruh sikap ilmiah terhadap prestasi belajar kognitif siswa, tetapi ada pengaruh sikap ilmiah terhadap prestasi belajar afektif siswa 4) ada interaksi antara model pembelajaran dan kreativitas terhadap prestasi belajar kognitif siswa, tetapi tidak ada interaksi antara model pembelajaran dan kreativitas terhadap prestasi belajar afektif siswa, 5) tidak ada interaksi antara model pembelajaran dan sikap ilmiah terhadap prestasi belajar kognitif siswa, tetapi ada interaksi antara model pembelajaran dan sikap ilmiah terhadap prestasi belajar afektif siswa, 6) ada interaksi antara kreativitas dan sikap ilmiah terhadap prestasi belajar kognitif siswa, tetapi tidak ada interaksi antara kreativitas dan sikap ilmiah terhadap prestasi belajar afektif siswa, 7) tidak ada interaksi antara model pembelajaran, kreativitas, dan sikap ilmiah siswa terhadap prestasi belajar kognitif dan afektif siswa.
Kata kunci: Metode JIGSAW dan GI (Group Investigation), Prestasi Belajar Kognitif dan Afektif, Kreativitas dan Sikap Ilmiah.   
ABSTRACT
The purpose of the research were to know the effect of cooperative learning using JIGSAW and GI, creativity, scientific attitude, and interaction on learning achievement.
This research used experimental method. The population of this research was all classes twelve grade of majoring in computer engineering and broadcasting networks program of SMK PGRI 6 Ngawi in The 2012-2013 academic year, which consisted of 5 classes. The samples were taken used random cluster sampling technique, those were 2 classes, namely XIITKJ1 learning using JIGSAW and XIIBRO1 learning using GI. The data in the form of students’ cognitive learning achievement were collected used test, while the scientific attitude, students’ creative learning, assessment of affective learning achievement. Data analysis technique used was the three- way analysis of variance with a 2x2x2 factorial design.
Based on the data analysis, it could be concluded: 1) there is an effect of JIGSAW and GI  toward students’ cognitive and affective achievement, 2) there is effect of creativity toward students’ cognitive and affective achievement, 3) there is not effect of Scientific Attitude toward students’ cognitive achievement, but there is effect of Scientific Attitude toward students’ affective achievement 4) there is interaction between learning model and creativity toward students’ cognitive achievement, but there is not interaction between learning model and creativity toward students’ affective achievement  5) there is not interaction between learning model and Scientific Attitude toward students’ cognitive achievement, but there is interaction between learning model and Scientific Attitude toward students’ affective achievement  6) there is interaction between creativity and Scientific Attitude toward students’ cognitive achievement, but there is not interaction between creativity and Scientific Attitude toward students’ affective achievement 7) there is not interaction between learning model, creativity and Scientific Attitude toward students’ cognitive and affective achievement.
Key words: JIGSAW dan GI (Group Investigation), Cognitive and Affective Achievement, creativity and scientific attitude.
