Abstract

The purpose of this research was to explain how the coherence of presentation among the components of mathematical proficiency in Trigonometry in high school mathematics textbooks. The method that used in this research was descriptive and the form was content analysis. Object of this research was a mathematical proficiency presentation in mathematics textbooks. The results showed that: (1) Coherence of presentation conceptual understanding in Trigonometry in mathematics textbooks A, B and C was classified enough; (2) Coherence between presentation of conceptual understanding and procedural fluency in Trigonometry in mathematics textbooks A and B was classified good, whereas C was classified enough; (3) Coherence between presentation of conceptual understanding and strategic competence in Trigonometry in mathematics textbooks A and B was classified good, whereas C was classified enough; and (4) Coherence between presentation of procedural fluency and adaptive reasoning in Trigonometry in mathematics textbooks A was classified very good, whereas B and C was classified enough
