Eksperimen Pembelajaran Matematika melalui Model Pembelajaran Group Investigation dan Think Pair Share Terhadap Hasil Belajar Matematika Ditinjau dari Kreativitas Siswa Kelas VIII SMP Negeri 1 Bulu Tahun Ajaran 2018/2019

The purpose of this study is to learn: (1) Differences in the Group Investigationmodel and the Think Pair Share on the learning outcomes of mathematics. (2) Differences in the interaction of student learning creativity towards the learning outcomes of mathematics. (3) Learning between the Group Investigationmodel and Think Pair Share the with students' creativity towards the mathematics learning outcomes. This study was conducted at SMP N 1 Bulu Sukoharjo in class VIII of the academic year 2018/2019. This type of research is quantitative with quasi-experimental.Sampel were taken 2 classes with cluster random sampling. Methods of collecting data using tests, questionnaires, and documentation. Data analysis techniques use analysis of road variants with unequal cells. Further testing using the Scheffe method '. Based on the results of the analysis with significance level 5% obtained conclusions: (1) The difference between the Group Investigationmodel and the Think Pair Share on the learning outcomes of mathematics is needed. The results of learning mathematics using the Think Pair Share learning model are better than the Group Investigation learning model (2) student creativity towards learning outcomes. Mathematics learning outcomes of students with a high level of creativity have no difference with students who have moderate creativity levels. But students with high levels of creativity are better at learning outcomes than students with low levels of creativity and students who have a high level of creativity learning compared to student with low creativity. (3) does not involve interaction between the, Group Investigation , Think Pair Sharelearning model and the creativity learning of students towards the learning outcomes of mathematics.
