abstract={This study aims to: 1) Describe validity, practicality, and effectiveness of learning devices based on metacognition approach developed on mathematical communication ability of students in State SMP 30 of Medan; 2) Describe the improvement of mathematical communication ability using learning devices based on the metacognition approach developed. Researchers develop learning devices based on a metacognition approach using the Dick & Carey development model. The learning devices produced from this study are the teacher¡¯s book and student¡¯s books. From the results of this study it was found that: 1) the developed learning devices fill the criteria of valid, practical, and effective in terms of their respective criteria; 2) in the first trial there was an increase in mathematical communication ability using learning devices developed in the low category, it¡¯s about 0.28 and in the second trial there was an increase in mathematical communication ability using learning devices developed in the medium category, it¡¯s about 0.56.},
