Abstract
Mathematics instructional in Junior High School (SMPN) 4 Baso, Agam conducted through lecture method. The student-centered learning has not been performed at instructional. Most of students (60%) have not been mastered of mathematics. One of the efforts to improve learning outcomes is to use the Pythagorean model as a learning media. This research aims to improve the learning outcomes of students used the Pythagorean model of the Pythagorean Theorem. The research used classroom action research design. The research subjects were VIII.1 grade students of SMPN 4 Baso, Agam in the 2015/2016 academic year of 20 students. Data collection instrument were tests and observation sheet. The test was used to know the learning outcomes of students in each cycle. Observation sheet was used to determine the instructional process at each cycle. Data were analyzed with descriptive statistics. The results showed that: The average score of the students learning outcome in the first cycle of 66.5, the second cycle of 75.5 so that was increasing in the average score of the first cycle to the second cycle. Percentage of mastery learning of students in the first cycle of 60%, in the second cycle of 95%. Thus there was an improved of mastery learning of students from the first cycle to the second cycle. It can be concluded that the mathematics instructional by using Pythagoras models can improve to learning outcomes of students.

Summary
Penelitian ini termasuk penelitian tindakan kelas yaitu penelitian oleh guru yang dilakukan secara kolaboratif untuk memperbaiki proses pembelajaran yang terjadi di dalam kelas sehingga tujuan pembelajaran dapat tercapai. Menurut Arikunto (2010) penelitian tindakan kelas adalah penelitian yang dilakukan oleh guru di kelas sendiri dengan tahap; (1) perencanaan (2) tindakan, (3) pengamatan, (4) refleksi. Menurut Arikunto (2010) penelitian tindakan kelas adalah suatu penelitian yang dilakukan berdasarkan adanya permasalahan nyata yang muncul di kelas, selanjutnya berdasarkan permasalan tersebut guru mencari alternatif cara-cara untuk mengatasinya dan menindaklajuti dengan tindakan nyata yang terencana dan dapat diukur tingkat keberhasilannya. Subjek penelitian adalah peserta didik kelas VIII.. Analisis data dilakukan secara deskriptif kualitatif yang meliputi reduksi data, penyajian data, dan penarikan kesimpulan yang diungkapkan oleh Miles dan Huberman (Moleong, 2006). Kriteria keberhasilan adalah minimum 85% peserta didik tuntas dalam belajar matematika
