<![CDATA[Abstrak:Tujuan utama penelitian ini adalah untuk mendeskripsikan penerapan pendekatan scientific pada model pembelajaran kooperatif tipe Student Teams Achievment Division (STAD) dalam upaya meningkatkan hasil belajar siswa pada materi perbandingan trigonometri di kelas X SMAN 1 Sigi. Rancangan penelitian mengacu pada model Kemmis dan Mc. Taggart, yang terdiri dari empat komponen, yaitu: (1) perencanaan, (2) pelaksanaan tindakan, (3) observasi dan (4) refleksi. Penelitian ini dilaksanakan dalam dua siklus dengan mengikuti fase-fase sebagai berikut: 1) apersepsi, memberikan motivasi dan menyampaikan tujuan pembelajaran, 2) menyajikan informasi, siswa mengamati satu contoh permasalahan yang terkait perbandingan trigonometri, mengajukan pertanyaan tentang informasi yang tidak dipahami, menalar permasalahan yang terkait perbandingan trigonometri untuk memperoleh kesimpulan. 3) mengorganisir siswa dalam tim-tim belajar, 4) membimbing kelompok bekerja dan belajar, siswa bersama-sama kelompok mengkomunikasikan hasil temuannya di depan kelas 5) Evaluasi, siswa mengeksplorasi dengan mengerjakan LKPD secara berkelompok 6) memberikan penghargaan.

Abstact: The main goal of this research is to describe “Scientific Approach Implementation on Cooperative Learning Model of Student Teams Achievement (STAD) type in an effort to increase the students learning achievement on Trigonometry Ratio Subject at the tenth grade of SMAN 1 Sigi. The research design refers to Kemmis and Mc Taggart Model that comprises (1) Planning, (2) Action Implementation, (3) Observation and Reflection. The obtained data are taken from the teachers’ and students’ activity data in the form of observation sheet, interview, and field note results. This research is conducted by using an scientific approach on cooperative learning model of Student Teams Achievement Division (STAD) type, that is guided by the phases as follows: (1) conveying the goal, and motivating students; (2) conveying information in which students observe phenomena and find out facts in the form of objective data, students raise the questions about unknown information or to get information from the observation results, students think logically to process data to draw conclusion; (3) organizing students in learning groups, (4) advising the teamwork and studying, students form a web of communication by discussing and raising the teamwork results; (5) evaluation, students explore by doing LKPD in groups; (6) giving appreciation.
