Abstract
This research is a qualitative research which aims to describe the ability of logical thinking and mathematical adaptive reasoning of seventh grade junior high school students in terms of the field dependent and field independent cognitive styles. The subjects in this study were seventh grade students of Serang City 7 State Junior High School as many as 6 students namely 3 students in field dependent cognitive style and 3 students in independent field cognitive style. The selection of research subjects was based on the results of the cognitive embeded figure test (GEFT) cognitive style test. Data collection techniques in this study are tests of the ability to think logically and adaptive reasoning, observation and interviews. The research results show that: 1) Logical thinking analysis, obtained dependent students are not independent in solving problems, because they have not been able to solve mathematically rational problems perfectly, have not been able to draw the right logical conclusions from the problems given. Then in writing down the solution, do not write down in detail what is known and asked. 2) Analysis of logical thinking, obtained independent students are already independent in solving problems, because they are able to provide reasonable arguments with their own language. Make a logical relationship between different concepts and facts without having to ask questions and guess and test based on reason in their own way. Can write down what is known and asked correctly and solve problems with your own ideas and thoughts. 3) Analysis of adaptive reasoning, obtained dependent students have not been able to give a decision on a problem. In addition, it has not been able to find patterns in a mathematical phenomenon appropriately. Then, dependent students seem confused and doubtful and write down the solution according to the teacher's method. 4) Analysis of adaptive reasoning, obtained independent students are already independent in solving problems, because the three are able to submit allegations with their own thoughts. Examine the validity of an argument in its own way and language. In addition, you can write down what you know and ask correctly and solve problems with your own ideas and thoughts, even though sometimes the answers are not right. 5) In the matter of logical thinking, dependent students only get an average of about 62.27% completeness, while independent students get 82.50%. Likewise in the case of adaptive reasoning, where dependent students only get an average of about 62.50% completeness, while independent students get 83.33%. So it is found that independent students have the ability to think and reason better than dependent students.

| Additional Information: | Penelitian ini adalah penelitian kualitatif yang bertujuan untuuk mendeskripsikan kemampuan berpikir logis dan penalaran adaptif matematis siswa SMP kelas VII ditinjau dari gaya kognituf field dependent dan field independent. Subyek dalam penelitian ini adalah siswa kelas VII SMP Negeri 7 Kota Serang sebanyak 6 orang siswa yakni 3 orang siswa bergaya kognitif field dependent dan 3 orang siswa bergaya kognitif field independent. Pemilihan subyek penelitian berdasarkan hasil tes gaya kognitif Group Embeded Figure Test (GEFT). Teknik pengumpulan data dalam penelitian ini adalah tes kemampuan berpikir logis dan penalaran adaptif, observasi dan wawancara. Adapun hasil penelitian menunjukkan bahwa: 1) Analisis berpikir logis, didapat siswa dependent tidak mandiri dalam menyelesaikan permasalahan, karena belum mampu menyelesaikan masalah matematis secara rasional dengan sempurna, belum dapat menarik kesimpulan logis yang tepat dari permasalahan yang diberikan. Kemudian dalam menuliskan penyelesaian, tidak menuliskan dengan rinci apa yang diketahui dan ditanyakan. 2) Analisis berpikir logis, didapat siswa independent sudah mandiri dalam menyelesaikan permasalahan, karena mampu memberikan argumen yang masuk akal dengan bahasanya sendiri. Membuat hubungan logis di antara konsep dan fakta yang berbeda tanpa harus banyak bertanya serta menduga dan menguji berdasarkan akal dengan cara sendiri. Dapat menuliskan yang diketahui dan ditanyakan dengan tepat serta menyelesaikan soal dengan ide dan pemikiran sendiri. 3) Analisis penalaran adaptif, didapat siswa dependent belum mampu memberikan keputusan terhadap suatu masalah. Selain itu, belum dapat menemukan pola pada suatu gejala matematis dengan tepat. Kemudian, Siswa dependent nampak bingung dan ragu dan menuliskan penyelesaian sesuai dengan cara guru. 4) Analisis penalaran adaptif, didapat siswa independent sudah mandiri dalam menyelesaikan permasalahan, karena ketiganya mampu mengajukan dugaan dengan pemikiran sendiri. Memeriksa kesahihan suatu argumen dengan cara dan bahasanyaa sendiri. Selain itu, dapat menuliskan yang diketahui dan ditanyakan dengan tepat serta menyelesaikan soal dengan ide dan pemikiran sendiri, walaupun terkadang jawaban yang diperoleh belum tepat. 5) Pada soal berpikir logis, siswa dependent hanya memperoleh rata-rata ketuntasan sekitar 62,27 %, sedangkan siswa independent memperoleh 82,50 %. Begitupun pada soal penalaran adaptif, dimana siswa dependent hanya memperoleh rata-rata ketuntasan sekitar 62,50 %, sedangkan siswa independent memperoleh 83,33%. Sehingga didapat bahwa siswa independent memiliki kemampuan berpikir dan menalar yang lebih baik daripada siswa dependent. | |||||||||
