Penelitian ini bertujuan untuk menghasilkan perangkat pembelajaran matematika bercirikan problem-based learning (PBL) yang valid, praktis, dan efektif untuk mengembangkan higher order thinking skills (HOTS) siswa SMA kelas X semester 2 berupa: rencana pelaksanaan pembelajaran (RPP) dan lembar kegiatan siswa (LKS) yang dilengkapi instrumen tes hasil belajar. Penelitian pengembangan ini menggunakan model pengembangan 4-D dari Thiagarajan dengan empat tahapan, yaitu: pendefinisian, perancangan, pengembangan, dan penyebaran. Uji coba dilaksanakan dalam tiga tahap, yaitu: uji coba ahli, uji coba terbatas, dan uji coba lapangan. Subjek uji coba dalam penelitian ini adalah guru dan siswa yang dipilih dari dua sekolah. Instrumen yang digunakan terdiri atas lembar validasi, penilaian guru, penilaian siswa, dan instrumen tes hasil belajar. Hasil penelitian menunjukkan bahwa perangkat yang dikembangkan telah memenuhi aspek validitas, kepraktisan, dan keefektifan.(1) Hasil validitas menunjukkan bahwa RPP dan LKS yang dikembangkan pada kategori valid dengan indeks Aiken pada RPP sebesar 0,69 dan LKS sebesar 0,70. (2) Hasil uji coba terbatas menunjukkan perangkat pembelajaran yang dikembangkan pada kategori praktis. (3) Hasil uji coba lapangan menunjukkan perangkat pembelajaran efektif ditinjau dari HOTS siswa dengan persentase ketuntasan secara klasikal subjek uji coba lebih dari 75%.Kata Kunci: pengembangan, perangkat pembelajaran matematika, problem-based learning, higher order thinking skills Mathematics teaching kits based on PBL to develop hots of senior high school students AbstractThis research is aimed at developing mathematics teaching kit based on problem-based learning which is valid, practical, and effective to develop the higher order thinking of grade X students senior high school in their second semester, which consists of lesson plan and students’ worksheet with test instrument. The research development used the model adapted from 4-D model developed by Thiagarajan with employing steps: defining, planning, developing, and disseminating. The tryout is conducted three steps: expert validation, limited tryout, and field tryout. The tryout subjects were teachers and students from two schools. The instruments used in this research were validation sheet, teacher’s assessment sheet, student’s assessment sheet, and test. The result of the research shows that the developed mathematics teaching kitbased on problem-based learning has met the aspect of validity, practicality, and effectiveness. (1) The result of validation shows that the lesson plan and the students’ worksheet are chategorized as valid with the Aiken analysis showing the index for the lesson plan has achieved 0.69 and the 0.70 for the students’ worksheet. (2) teh result of limited tryout shows that the developed of mathematics teaching kit is practical. (3) the result of field tryout shows that the developed of mathematics teaching is effective interm students’s HOTS with percentage of clasisical mastery subjects reached 75%.Keywords: development, mathematics teaching kit, problem-based learning, higher order thinking skills
