Efektivitas Problem Based Learning Ditinjau dari Kemampuan Komunikasi Matematis Siswa

Abstract

This research was a quasi-experimental research that aimed to find out the effectiveness of Problem Based Learning in terms of students' mathematical communication skill. The population of this research was 63 students of grade VIII in SMP Negeri 13 Bandarlampung that were distributed in two classes. The entire population was used as a sampleby using The Randomized posttest-only control group design. The data of the research was the data of students' mathematical communication skill that acquired through the test. Based on the result of the similarity test of two averages showed that the students mathematical communication skill by using Problem Based Learning was higher than conventional learning, but the percentage of students who was taught by Problem Based Learning did not achieve 60%. Thus, Problem Based Learning was not effective in terms of students' mathematical communication skill.

Penelitian ini merupakan penelitian eksperimen semu yang bertujuan untuk mengetahui efektivitas Problem Based Learning ditinjau dari kemampuan komunikasi matematis. Populasi penelitian ini adalah 63 siswa kelas VIII di SMP Negeri 13 Bandarlampung yang terdistribusi dalam dua kelas. Seluruh populasi tersebut merupakan sampel, dengan desain penelitian the randomized posttest-only control group design. Data penelitian berupa data kemampuan komunikasi matematis siswa yang diperoleh melalui tes. Berdasarkan hasil uji kesamaan dua rata-rata diperoleh bahwa kemampuan komunikasi matematis siswa dengan Problem Based Learning lebih tinggi dari pembelajaran konvensional, akan tetapi persentase siswa denganProblem Based Learning tidak mencapai 60%. Dengan demikian Problem Based Learning tidak efektif ditinjau dari kemampuan komunikasi matematis siswa.
