Abstract

Penelitian ini bertujuan untuk menguji keefektifan pendekatan Problem-Based Learning (PBL) dan Contextual Teaching and Learning (CTL) ditinjau  dari kemampuan komunikasi matematis dan motivasi belajar siswa dan manakah yang lebih efektif diantara keduanya. Penelitian ini merupakan penelitian eksperimen semu. Populasinya adalah seluruh siswa kelas VIII SMP Negeri 1 Margasari Kabupaten Tegal. Sampel penelitian kelas VIII-A dan VIII-H. Untuk menguji keefektifan pendekatan pembelajaran data dianalisis dengan uji one sample    t- test pada taraf signifikansi 5%. Untuk mengetahui perbedaan keefektifan pembelajaran data diukur dengan  uji Hotelling’s Trace pada taraf signifikansi 5% dan selanjutnya digunakan uji independent sample t-testuntuk mengetahui pembelajaran mana yang lebih efektif. Hasil penelitian menunjukkan bahwa: pendekatan PBL dan CTL efektif ditinjau dari kemampuan komunikasi matematis dan motivasi belajar siswa dan pendekatan PBL lebih efektif dibandingkan dengan pendekatan CTL ditinjau dari motivasi belajar siswa, namun tidak lebih efektif ditinjau dari kemampuan komunikasi matematis.Kata Kunci:  pendekatan Problem-Based Learning, pendekatan Contextual Teaching and Learning,   kemampuan komunikasi matematis, dan motivasi belajar siswa. The Effectiveness of PBL Approach and CTL Viewed from Mathematical Communication and Learning Motivation of Students Junior High School  AbstractThis study aims to examine  the effectiveness of Problem Based-Learning (PBL) and Contextual Teaching and Learning (CTL) viewed from students’ mathematical communication ability and learning motivation and which more effective instruction between PBL approach and CTL approach. This study was quasi experiment research. The population covered all grade VIII students of SMP Negeri 1 Margasari in Tegal Regency.  The sample of class VIII-A and VIII-H. To test the effectiveness of the PBL and CTL approaches, the data were analyzed using the one-sample t-test at the significance level of 5%. To determine differences in the effectiveness of mathematics teaching data were analyzed using Hotteling Trace at the significance level of 5% and followed by independent sample t- test to determine which approach was more effective. The results of this study show that: the PBL approach and CTL is effective to increase students’ communication ability and learning motivation and the PB L approach is more effective than the CTL approach viewed from students’ learning motivation but not more effective viewed from mathematical communication ability .Keywords: Problem-Based Learning approach, Contextual Teaching and Learning approach, mathematical communication ability, student’s learning motivation.
