<![CDATA[The Profile of Metacognition of Junior High School Students in Solving Open Problems. This study was aimed to reveal the profile of metacognition of junior high school students with impulsive-reflective cognitive style in solving open-problems concerning plan-figure-geometry. This study was conducted at the seventh grade of Junior High School and the subjects were one student of impulsive cognitive style and one student of reflective cognitive style and both had relatively similar mathematics ability. The data were collected through test and interview. The results show that students, either the impulsive or reflective cognitive style, have similar metacognition style profile in the step of understanding the problems but they were different in the stage of arranging the plan of problem solving, executing the plan for solving problem, and re-evaluating the result of the problem solving. Profil Metakognisi Siswa SMP dalam Memecahkan Masalah Terbuka. Penelitian ini bertujuan untuk mengungkapkan profil metakognisi siswa SMP yang bergaya kognitif impulsif dan kognitif reflektif dalam memecahkan masalah terbuka materi geometri bangun datar. Penelitian ini dilakukan di kelas VII SMP dengan subjek satu siswa bergaya kognitif impulsif dan satu siswa bergaya kognitif reflektif dan keduanya memiliki kemampuan matematika relatif sama. Data dikumpulkan dengan cara pemberian tes dan wawancara. Analisis data dilakukan melalui reduksi data, penyajian data, penafsiran data dan penarikan kesimpulan. Hasil penelitian menunjukkan bahwa subjek impulsif dan subjek reflektif memiliki profil metakognisi yang sama pada tahap memahami masalah, dan berbeda profil metakognisinya pada tahap membuat rencana, melaksanakan rencana dan memeriksa kembali hasil pemecahan masalah.]]>
