<![CDATA[Penelitian ini bertujuan untuk mendeskripsikan keefektifan pembelajaran trigonometri dengan menggunakan pendekatan problem posing dan pendekatan open-ended ditinjau dari HOTS siswa. Penelitian ini merupakan penelitian eksperimen semu. Penelitian ini menggunakan satu kelompok eksperimen dan satu kelompok kontrol. Populasi penelitian ini adalah seluruh siswa kelas X SMA Negeri 3 Bantul. Sampel penelitian sebanyak dua kelas yang dipilih secara acak. Instrumen penelitian yang digunakan adalah instrumen tes HOTS. Data dianalisis menggunakan uji one sample t-test dan two independent sample t-test. Hasil penelitian menunjukkan bahwa: pendekatan problem posing efektif ditinjau dari HOTS; pendekatan open-ended efektif ditinjau dari HOTS; Pendekatan open-ended tidak lebih efektif dibandingkan dengan pendekatan problem posing ditinjau dari HOTS.Kata Kunci: problem posing, open-ended, higher order thinking skills (HOTS) The Effectiveness Using Problem Posing Approach and Open-Ended Approach in Terms of the HOTS AbstractThis study aims to describe the effectiveness of teaching Trigonometry using the Problem Posing Approach and Open-Ended Approach in terms of the HOTS of High School Students. This research was a quasi-experimental. The research population comprised nine classes of Year X student of SMA Negeri 3 Bantul. The sample consisted of two classes that were randomly established. The instruments used in the research was HOTS test. The data analysis techniques consisted of the one sample t-test and two independent sample t-test. The results of the research show that: the problem posing approach is effective in terms of HOTS; the open-ended approach effective in terms of HOTS; and there is no difference in effectiveness between the problem posing approach and open-ended approach in terms of HOTS.Keywords: problem posing, open-ended, higher order thinking skills (HOTS)]]>
