Ethnomathematics is one of the efforts to learn mathematics contained in a culture. The culture in question is the habits, attitudes or activities carried out by the community to preserve culture. One of the cultural activities in which there is ethnomathematics is the culture carried out by the people of Wuluhan District, Jember Regency. One of the districts known as the largest producer of tobacco. There is ethnomathematics in the tobacco drying process carried out by the Wuluhan community. There are mathematical concepts such as counting, measuring and designing in the process. The purpose of this study was to explore the existence of ethnomathematics in the activity of drying tobacco leaves in the Wuluhan community. The method used for this research is data collection using observation and interviews. In the harvesting process, which is carried out in stages, there is the concept of counting. For the mathematical concept of measuring, there are stages of measuring the distance between tobacco leaves and determining the length of the rope. In the design activity there is a mathematical concept in the form of making a tobacco warehouse.

HOTS is the ability to combine and develop newly acquired information and prior knowledge to solve non-routine problems. HOTS refers to the revised Bloom's Taxonomy which consists of analyzing, evaluating, and creating. However, this study was only analyzing (C4) and evaluating (C5). This study aimed to describe the HOTS profile of students in solving geometry problems. This type of research was descriptive qualitative research with the subject consisting of two students with high learning ability, each of whom was selected to represent two different Euclid Geometry classes. Data collection consisted of solving HOTS problems and unstructured interviews. The results showed that the two subjects had not been able to achieve high order thinking ability indicators. Students' higher-order thinking skills still need to be improved. Mathematics learning should designing considering the critical and creative thinking aspects to develop students' HOTS learning should be designed by considering critical and creative thinking aspects to develop students' HOTS.

Penelitian ini untuk mendeskripsikan kompetensi pedagogik mahasiswa Program Studi Pendidikan Matematika di IKIP Budi Utomo dalam menyusun tes Matematika berbasis HOTS. Ini ini adalah penelitian kualitatif dengan teknik Focus Group Discussion (FGD). Hasil penelitian menunjukkan bahwa kompetensi pedagogik mengembangkan instrument penilaian dan evaluasi dalam pembelajaran Matematika memerlukan kemampuan pedagogik yang lain yaitu: kemampuan memahami karakteristik peserta didik, teori belajar, memanfaatkan teknologi informasi dan komunikasi, dan kemampuan berkomunikasi. Mahasiswa hanya dapat menyusun soal HOTS pada level C4 atau menganalisis dan masih memerlukan bantuan dari dosen atau fasilitator untuk dapat menyusun soal HOTS dengan baik.

Penelitian ini mempunyai tujuan untuk mendeskripsikan transformasi taksonomi Bloom dalam evaluasi pembelajaran berbasis Higher Order Thinking Skills atau HOTS. Penelitian ini merupakan penelitian deskriptif menggunakan metode kajian pustaka. Evaluasi merupakan penilaian terhadap hasil belajar peserta didik. Ada tiga hasil belajar yang dapat dinilai. Salah satunya adalah kemampuan kognitif atau pengetahuan. Penilain ini dilakukan sesuai dengan ranah kognitif taksonomi Bloom. Namun,  mengalami transformasi atau perubahan pada tahun 2001. Perubahan tersebut berupa C1, C2, C3, C4, C5, dan C6 dari pengetahuan, pemahaman, penerapan, analisis, sintesis, dan evaluasi menjadi mengingat, memahami, menerapkan, menganalisis, mengevaluasi, dan mencipta. Selain itu, revisi taksonomi Bloom menunjukkan adanya perubahan dari kata benda menjadi kata kerja. HOTS meliputi menganalisis, mengevaluasi, dan mencipta. Menyusun soal HOTS harus memperhatikan kata kerja operasional dari C4, C5, dan C6 taksonomi Bloom yang sudah direvisi. HOTS merupakan keterampilan berpikir tingkat tinggi yang berada pada level penalaran.
