PROFIL KOMUNIKASI MATEMATIKA TULIS SISWA SMP DALAM MEMECAHKAN MASALAH MATEMATIKA DITINJAU DARI KEPRIBADIAN EXTROVERT DAN INTROVERT

THE WRITTEN MATHEMATICS COMMUNICATION PROFILE OF JUNIOR HIGH SCHOOL STUDENTS IN SOLVING MATHEMATICS PROBLEMS TOWARDS EXTROVERT AND INTROVERT PERSONALITY

Tujuan penelitian ini adalah mendeskripsikan profil komunikasi matematika tulis siswa SMP dalam memecahkan masalah matematika ditinjau dari kepribadian extrovert dan introvert. Penelitian ini adalah penelitian deskriptif dengan pendekatan kualitatif. Subjek penelitian terdiri dari satu siswa berkepribadian introvert dan satu siswa berkepribadian extrovert. Instrumen pada penelitian ini adalah angket kepribadian Myers Briggs Type Indicators, tes kemampuan matematika, dan tes komunikasi matematika tulis. Hasil penelitian menunjukkan bahwa komunikasi matematika tulis siswa berkepribadian introvert sebagai berikut: siswa menuliskan hal-hal yang diketahui dan ditanya dengan akurat, lengkap, dan tidak lancar. Siswa menyatakan gambar ke dalam suatu barisan bilangan secara akurat, lengkap, dan tidak lancar. Siswa menuliskan aturan  secara akurat, lengkap, dan lancar. Selanjutnya siswa menuliskan langkah–langkah perhitungan secara akurat, lengkap, tetapi tidak lancar. Pada tahap akhir siswa tidak menuliskan kesimpulan. Sedangkan komunikasi matematika tulis siswa berkepribadian extrovert sebagai berikut: siswa menuliskan hal-hal  yang diketahui dan ditanya secara akurat, tidak lengkap, dan tidak lancar. Siswa tidak menyatakan gambar ke dalam bahasa, simbol, ide, atau model matematika. Siswa menuliskan aturan secara tidak lengkap, tidak akurat, dan tidak lancar. Selanjutnya siswa menuliskan langkah–langkah perhitungan dengan lengkap, tidak akurat, dan tidak lancar. Siswa menuliskan kesimpulan secara lengkap, tidak akurat, dan tidak lancar.

This study aims to describe the written mathematics communication profile of junior high school students in solving mathematics problems towards extrovert and introvert personality. This research was a descriptive study with a qualitative approach. The subjects of this study were one introvert student and one extrovert student. The instruments used in this study were the Myers Briggs Type Indicators personality questionnaire, math ability tests, and written mathematics communication tests. The findings of introvert students’ written mathematics communication were as follows: student wrote things that were known and asked accurately, completely, but not fluently. Student stated the picture into a sequence of numbers accurately, completely, yet not smoothly. Student wrote the rules accurately, completely, and fluently. In addition, student wrote the calculation steps accurately, completely, but not smoothly. However, at the final stage the student did not write any conclusion. In contrats, extrovert students' written mathematics communication were as follows: student wrote things that were known and asked accurately, incompletely, and not fluently. Student did not state pictures into language, symbols, ideas, or mathematical models. Student wrote the rules incompletely, inaccurately, and not smoothly. Furthermore, student wrote the calculation steps completely, yet inaccurately, and not smoothly. Furthermore, student wrote the conclusions in complete yet inaccurate and not fluent.
