Kemampuan berpikir kreatif matematis siswa penting untuk dimiliki oleh siswa. Salah satu yang mampu mengukur kemampuan berpikir kreatif matematis siswa yaitu dengan pemberian soal open ended. Namun, soal open ended dengan konteks budaya untuk melatih kemampuan berpikir kreatif matematis siswa masih terbatas ketersediaannya. Penelitian ini bertujuan untuk menghasilkan soal open ended dengan konteks budaya untuk melatih kemampuan berpikir kreatif matematis siswa yang valid, praktis dan efektif. Penelitian ini merupakan penelitian pengembangan dengan model Tessmer yang terdiri dari tahapan self evaluation, expert review, one-to-one, small group, dan field test. Subjek ujiketerbacaan tahap one to one dan small group dalam penelitian ini adalah siswa SMP YPPU Sigli dan subjek field test adalah siswa SMP Negeri 2 Sigli. Instrumen yang digunakan dalam penelitian ini yaitu lembar validasi, lembar kepraktisan dan lembar keefektifan. Teknik analisis data dilakukan oleh peneliti berdasarkan tahapan Tessmer. Hasil penelitian yang dihasilkan yaitu 8 soal open ended dengan konteks budaya untuk melatih kemampuan berpikir kreatif matematis siswa yang valid, praktis dan efektif.

The ability to think creatively mathematically is important for students to have. One that is able to measure students' mathematical creative thinking ability is by giving open ended questions. However, the availability of open ended questions with a cultural context to train students' mathematical creative thinking skills is still limited. This study aims to produce open ended questions with a cultural context to train students' mathematical creative thinking skills which are valid, practical and effective. This research is a development research with the Tessmer model consisting of self-evaluation, expert review, one-to-one, small group, and field test stages. The subjects of the one to one and small group readability tests in this study were students of SMP YPPU Sigli and the subjects of the field test were students of SMP Negeri 2 Sigli. The instruments used in this study were validation sheets, practicality sheets and effectiveness sheets. Data analysis techniques were carried out by researchers based on Tessmer's stages. The results of the research are 8 open ended questions with a cultural context to train students' mathematical creative thinking skills which are valid, practical and effective.
