Salah satu materi SMP kelas VII adalah aritmatika sosial. Materi ini sangat penting dijadikan sebagai bekal menjalani kehidupan di masyarakat dan melatih siswa untuk berpikir kreatif serta kritis dalam melaksanakan kegiatan jual-beli. Sejalan dengan kurikulum 2013, dimana kurikulum ini mendorong adanya keterampilan Higher Order Thinking Skills (HOTS). Pada pelaksanaannya tidak semua kemampuan HOTS dapat tersaji, dikarenakan kendala waktu pengerjaan dan kemampuan siswa. Selain itu, soal masih berkonteks lingkungan sekolah sehingga belum memuat konteks lahan basah. Untuk mengatasi permasalahan tersebut diperlukan tes formatif yang dapat mengasah kemampuan berpikir tingkat tinggi siswa dan kontekstual. Menghasilkan perangkat tes formatif berbasis HOTS materi aritmatika sosial dengan konteks lingkungan lahan basah yang valid menjadi tujuan dalam penelitian ini. Metode penelitian yang digunakan adalah penelitian pengembangan dengan model formative research yang diadaptasi dari Tessmer. Tahapan penelitian hanya dilakukan sampai tahap expert reviews dikarenakan kondisi pandemi Covid-19. Validasi dilakukan oleh tiga orang ahli. Hasil penelitian berupa 30 butir soal tes formatif pilihan ganda berbasis HOTS. Berdasarkan kevalidan tes formatif diperoleh skor rata -rata sebesar 3,49 dari segi materi, konstruksi, dan bahasa. Dengan demikian kriteria kevalidan tes formatif matematika pada materi aritmatika sosial berbasis HOTS untuk siswa SMP kelas VII dengan konteks lingkungan lahan basah dikatakan sangat valid. Kata kunci: tes formatif, aritmatika sosial, HOTS, konteks lingkungan lahan basah Abstract: One of the material for SMP class VII is social arithmetic. This material is very important as a provision to live life in society and train students to think creatively and critically in carrying out buying and selling activities. In line with the 2013 curriculum, this curriculum encourages Higher Order Thinking Skills (HOTS). In practice, not all HOTS abilities can be presented, due to time constraints and student abilities. In addition, the question is still in the context of the school environment so that it does not include the context of wetlands. To overcome these problems, formative tests are needed that can hone students' higher-order and contextual thinking skills. Generating a formative test kit based on HOTS social arithmetic material with a valid wetland environmental context is the goal of this research. The research method used is development research with a formative research model adapted from Tessmer. The research stage was only carried out until the expert reviews stage due to the Covid-19 pandemic. Validation was carried out by three experts. The results of the study were 30 items of the HOTS-based multiple choice formative test. Based on the validity of the formative test, an average score of 3.49 was obtained in terms of material, construction, and language. Thus, the criteria for the validity of the mathematical formative test on HOTS-based social arithmetic material for seventh grade junior high school students with the context of a wetland environment are said to be very valid. Keyword: formative tests, social arithmetic, HOTS, wetland environmental context
