摘要：Tujuan penelitian ini untuk mengetahui keefektifan model pembelajaran Connecting,Organizing,Reflecting,and Extending (CORE) berbantuan LKPD terhadap kreativitas matematis siswa kelas VII pada materi segitiga. Populasi dalam penelitian ini adalah siswa kelas VII SMP Negeri 2 Semarang tahun pelajaran 2012/2013. Pemilihan sampel dengan cara cluster random sampling,diperoleh siswa VII E sebagai kelas eksperimen dan kelas VII H sebagai kelas kontrol. Kelas eksperimen diajar dengan model pembelajaran CORE berbantuan LKPD,sedangkan kelas kontrol diajar dengan pembelajaran konvensional. Pengambilan data diperoleh dengan metode dokumentasi untuk mendapatkan data awal berupa nilai ulangan tengah semester genap matematika dan metode tes untuk memperoleh kreativitas matematis siswa yang kemudian dianalisis dengan uji ketuntasan dan uji kesamaan dua rata-rata. Hasil penelitian adalah (1) kreativitas matematis siswa kelas eksperimen mencapai ketuntasan belajar,baik ketuntasan individual maupun ketuntasan klasikal; dan (2) kreativitas matematis siswa kelas eksperimen lebih baik daripada kelas kontrol. Peneliti menyarankan bahwa model pembelajaran CORE berbantuan LKPD dapat digunakan sebagai alternatif model pembelajaran untuk menumbuhkembangkan kreativitas matematis siswa.
其他摘要：Purpose of this research was to determine the effectiveness of Connecting,Organizing,Reflecting,and Extending (CORE) learning model assisted by worksheet towards students’ mathematical creativity grade VII in triangles material. Population in this research was students of grade VII of SMP Negeri 2 Semarang 2012/2013 academic year. The research samples were taken by using cluster random sampling and found VII E as an experiment class and VII H as a control class. The experiment class was taught by CORE learning model assisted by worksheet,while the control class was taught by conventional learning. Data were obtained by documentation method to get initial data in the form of mathematics midterm score of even semester and test method to determine students’ mathematical creativity which was analyzed by learning mastery test,individually and classically and similarity test of two means. Results of this research were (1) students’ mathematical creativity of the experiment class has reached learning mastery,individually and classically,(2) students’ mathematical creativity of the experiment class was better than the control class. Researcher suggests that CORE learning model assisted by worksheet can be used as a learning model alternative to develop students’ mathematical creativity.
