Abstract

Penelitian ini bertujuan untuk mendeskripsikan pengaruh pendekatan contextual teaching and learning (CTL) dengan setting kooperatif tipe kancing gemerincing terhadap kemampuan komunikasi matematis, kepercayaan diri, dan prestasi belajar matematika siswa SMP. Penelitian ini merupakan jenis penelitian eksperimen semu dengan dua kelompok yaitu kelompok eksperimen dan kelompok kontrol. Untuk melihat pengaruh perlakuan terhadap ketiga variabel dependen secara simultan, digunakan uji statistik Multivariate Analysis of Variance (Manova), sedangkan untuk menganalisis pendekatan manakah yang lebih unggul terhadap masing-masing variabel dependen, digunakan uji statistik Independent Sample T-test. Hasil penelitian pada taraf signifikan 5% menunjukkan bahwa ada pengaruh pendekatan CTL dengan setting kooperatif tipe kancing gemerincing terhadap kemampuan komunikasi matematis, kepercayaan diri, dan prestasi belajar matematika pada siswa SMP. Berdasarkan analisis yang dilakukan, pembelajaran matematika menggunakan pendekatan CTL dengan setting kooperatif tipe kancing gemerincing lebih unggul daripada pendekatan konvensional dalam hal kemampuan komunikasi matematis, kepercayaan diri, dan prestasi belajar matematika pada siswa SMP.Kata Kunci: contextual teaching and learning, kancing gemerincing (talking chips), komunikasi matematis, percaya diri, dan prestasi belajar matematika. Effect of CTL Approach in Cooperative Setting of Talking Chips Type on Junior High School Student’s Mathematical Communication Skill, Self-Confidence, and Mathematics Learning Achievement AbstractThis study aims to describe the effect of contextual teaching and learning (CTL) approach in cooperative setting of talking chips type on junior high school student’s mathematical communication skill, self-confidence, and mathematics learning achievement.
