Not many teachers creatively develop critical thinking skills during the learning process. The consequence of the implementation of the 2013 curriculum is the use of a scientific approach to learning, including mathematics. Steps in scientific learning include: (1) observing; (2) ask; (3) collecting information; (4) associate; and (5) communicating. These five steps provide great opportunities for students to be able to develop mathematical critical thinking skills. This study describes the implementation of a scientific approach in learning mathematics, especially in improving mathematical critical thinking skills.

Masih banyak siswa yang merasa bingung manakala harus membayangkan kemudian menggambarkan setiap objek bangun ruang karena pada dasarnya materi bangun ruang banyak menggunakan visualisasi model matematika yang secara konkret tidak nyata dan tidak selalu ada dalam kehidupan sehari-hari. Kesulitan tersebut menyebabkan siswa tidak dapat menyelesaikan persoalan-persoalan pada materi bangun ruang. Hal ini menggambarkan masih rendahnya kemampuan abstraksi matematis siswa. Salah satu metode pembelajaran yang dapat meningkatkan kemampuan abstraksi matematis adalah pembelajaran problem posing berkelompok. Tujuan penelitian ini adalah (1) mendeskripsikan kesulitan siswa berpikir abstrak matematika dalam pembelajaran problem posing berkelompok; (2) mengetahui faktor-faktor yang menyebabkan kesulitan siswa berpikir abstrak matematika dalam pembelajaran problem posing berkelompok. Penelitian ini menggunakan penelitian dengan pendekatan kualitatif dan bersifat deskriptif. Subyek penelitian ini adalah siswa-siswa kelas X yang berjumlah 36 siswa. Instrumen yang digunakan dalam penelitian ini adalah soal tes kemampuan abstraksi matematis, angket serta pedoman wawancara. Hasil penelitian menunjukkan masih banyak siswa yang mengalami kesulitan berpikir abstrak matematika dalam pembelajaran problem posing berkelompok diantaranya adalah (1) siswa kurang penguasaan konsep; (2) siswa tidak melakukan pengalaman langsung dengan objek; (3) siswa kurang mampu mengaplikasikan konsep pada konteks yang sesuai; dan (4) siswa mengalami kesulitan dalam memanipulasi objek matematis yang abstrak. Sedangkan faktor-faktor yang menyebabkan siswa sulit berpikir abstrak berasal dari faktor ekstern yaitu minimnya penggunaan media alat peraga dalam pembelajaran.
