Penerapan Model Pembelajaran Kooperatif Tipe Numbered Head Together (Nht) Terhadap Kemampuan Pemahaman Matematis Dan Kemampuan Komunikasi Matematis Siswa Smp

This study examines, Improving Mathematical Understanding Ability and Mathematical Communication Ability and differences between students who apply Numbered Head Together (NHT) Cooperative Learning Models with students who obtain conventional learning models, in terms of the mathematical understanding ability and mathematical communication abilities (gender and overall ) and the relationship between students' mathematical understanding abilities and mathematical communication skills. The method used in this study is embedded type mixed methods. The sample used is two classes from eight existing classes. The results showed that 1) Improvement of mathematical understanding and communication skills of students who applied the Numbered Head Together (NHT) Learning Model were better than students who used conventional learning models of the overall category. 2) for the gender category, the improvement of mathematical understanding and communication skills of male students who apply the Numbered Head Together (NHT) Learning Model is no better than male students who use conventional learning models. 3) There is no relationship between mathematical understanding ability and mathematical communication ability
