Higher Order Thinking Skills (HOTS) merupakan kemampuan yang perlu dimiliki siswa untuk menghadapi perubahan dan perkembangan zaman saat ini. Guna mengoptimalisasikan kemampuan HOTS siswa, salah satu cara yang dapat dilakukan adalah dengan mengembangkan soal HOTS. Hal ini disebabkan, tanpa adanya soal HOTS, akan sulit untuk mengukur pencapaian kemampuan HOTS siswa. Namun, masih ada sekolah yang belum menggunakan soal HOTS dalam pembelajaran. Oleh karena itu, pelatihan penyusunan soal HOTS perlu diberikan kepada guru-guru yang belum menggunakan soal HOTS dalam pembelajaran. Metode pelaksanaan pelatihan dilakukan dengan memberikan materi terkait definisi dan karakteristik soal HOTS, serta bagaimana menyusun soal HOTS tersebut. Secara keseluruhan, kegiatan pelatihan sudah berjalan cukup baik. Berdasarkan angket yang diberikan kepada guru, semua peserta menyukai pelaksanaan kegiatan pelatihan yang telah dilakukan, terlihat dari rata-rata respon sebesar 93.24% dan berada pada kategori sangat baik.. Selain itu, peserta pelatihan telah menyusun soal HOTS di mata pelajaran masing-masing. Ditinjau dari rata-rata skor pretes sebesar 41.38 dan rata-rata skor postes sebesar 51.38, berarti telah terjadi peningkatan pada skor postes. Namun, jika dilihat dari soal HOTS yang telah dihasilkan, masih ada soal yang belum memenuhi karakteristik soal HOTS, sehingga masih memerlukan perbaikan lebih lanjut.Kata kunci—guru SMA, HOTS, pelatihan

Character education and learning mathematics are often considered as two different things. Whereas character education is one of the focuses of the Kurikulum Merdeka through the Profil Pelajar Pancasila, which can be instilled in all fields of study. One way to provide character education in mathematics learning is through inculcating habits of mind. This paper aims to find out whether character education through instilling habits of mind can support the achievement of students' mathematical cognitive abilities. The method used in writing this paper is literature study or literature review. From the results of the literature study, it is found that character education can be carried out by instilling habits of mind. This is because the habits of mind have 16 indicators which are positive characters. Besides being able to develop positive character, character education through inculcating habits of mind can also support the achievement of students' cognitive abilities, which can also be seen from several previous studies. This is due to the positive characters that have been embedded in students, for example, such as the characters of perseverance, curiosity, critical, analytical, communication, and empathy. This means that by providing character education through instilling habits of mind, not only positive character will be formed in students, but students' cognitive achievement will also be more optimal.
