Berdasarkan hasil observasi dan wawancara hasil belajar kognitif matematika siswa kelas IV SD Gugus Larasati belum mencapai kriteria ketuntasan minimal, hal ini disebabkan siswa mengalami kesulitan dalam menyelesaikan soal cerita. Model yang digunakan cenderung berpusat pada guru.Penelitian ini bertujuan untuk menguji keefektifan model Problem Based Learningberbantuan media tangram terhadap hasil belajar matematika siswa. Penelitian ini menggunakan metode kuantitatif dan jenis penelitian quasi eksperimen dengan desain nonequivalent control group design. Teknik sampel yang digunakan adalah cluster random sampling yaitu pengambilan sampel secara acak. Pengumpulan data penelitian menggunakan tes, observasi dan dokumentasi. Hasil penelitian menunjukkan bahwa hasil belajar siswa kelas eksperimen lebih tinggi dari KKM; hasil belajar siswa kelas eksperimen lebih baik dari kelas kontrol dengan nilai. Rata-rata n-gain kelas eksperimen masuk kategori sedang dan rata-rata n-gain kelas kontro masuk kategorirendah.Berdasarkan hasil penelitian dapat disimpulkan bahwa penerapan model PBL berbantuan media tangram efektif terhadap hasil belajar matematika kelas IV SD Gugus Larasati. Kata kunci:hasil belajar matematika, model Problem Based Learning (PBL), tangram. ABSTRACT Based on the results of observations and interviews cognitive learning outcomes of mathematics of grade 4 th elementary school students at Larasati Cluster had not reached the minimum completeness criteria because students have difficulty in solving story problems. The model usedis teacher-centered. This study aimed to test the effectiveness of the Problem Based Learning model assisted by tangram media towards students’ mathematics learning outcomes. This study used quantitative method and the type of experimental research was quasi experimental with non-equivalent control group design. The sampling technique used was cluster random sampling. The data instruments were tests, observation and documentation. The results of the study test showed that the experimental class student learning outcomes were higher than minimum criteria;student learning outcomes of the experimental class are better than the control class. The average of n-gain in the experimental class was moderate and the control class was low. Based on the results of the study it can be concluded that the application of the PBL model assisted by tangram was effective towards the mathematics learning outcomes of the 4 thgradestudents elementary schoolsin Larasti Cluster. Keywords: mathematics learning outcomes, Problem Based Learning (PBL) model, tangram.
