The purpose of this study is to provide alternative learning options, with a realistic mathematics education learning design or RME on quadrilaterl material for Junior High School students. This writing uses instructional design to develop a learning model. Learning development is done by analyzing needs and learners. Performance objectives and learning outcomes are discussed in detail and adapted to instructional objectives. The results of this study indicate that a quadrilateral learning design by applying the RME approach is recommended for educators in conducting quadrilateral learning. This happens because learning is based on real life or situations that can be imagined by students which are in accordance with RME characteristics, so that they can help students understand quadrilaterals.

Higher order thinking skills in learning are the application of thinking processes to complex situations. Every student can think, but most students need encouragement and guidance for higher order thinking processes. This study uses the Instructional Development Model (MPI). This study aims to explain the outline of the activities planned to design learning in cube VIII material, the development of learning objectives, the expected results, and practice questions that require the use of high-level skills. Learning activities that apply RME principles guide the implementation of processes that lead to HOTS-oriented problem-solving abilities. Several efforts must be made to improve students' higher order thinking skills in mathematics, namely: (1) involving students in non-routine problem solving activities; (2) facilitating students to develop the ability to analyze and evaluate (critical thinking) and creative abilities (creative thinking); and (3) encourage students to construct their own knowledge, so that learning becomes meaningful for students. It is hoped that educators can apply the characteristics of RME by using learning designs based on real life or situations that can be imagined by students, because this article shows that the RME design has the potential to improve the HOTS ability of junior high school students, especially in the topic of cubes.

Tujuan penelitian ini untuk mengetahui penerapan pembelajaran kooperatif tipe scramble dengan pendekatan kontekstual dalam meningkatkan kemampuan pemahaman konsep matematis siswa pada segiempat dan segitiga kelas VII. Penelitian PTK ini dilaksanakan dalam tiga siklus yang terdiri dari perencanaan, pelaksanaan, observasi, analisis dan refleksi. Subjek penelitian (SP) sebanyak 6 siswa kelas VII MTsN 16 Jakarta. Penelitian ini menerapkan tahapan model kooperatif scramble dan tujuh komponen kontekstual. Setiap pertemuan siswa diberikan LKS sebagai perangkat pembelajaran yang berisi pertanyaan pemandu sebagai wujud kegiatan inkuri, sehingga siswa dapat menemukan konsep yang sedang dipelajari yang disesuaikan dengan indikator kemampuan pemahaman konsep. Hasil penelitian menyatakan bahwa kemampuan pemahaman konsep matematis siswa mengalami peningkatan. Hal tersebut  dilihat dari proses siswa dalam mengikuti kegiatan pembelajaran dan juga peningkatan nilai rata-rata tes siklus SP. Hasil siklus I sebesar 78,56, siklus II 88,68 dan siklus III sebesar 93,44. Sehingga dapat disimpulkan bahwa model pembelajaran kooperatif tipe scramble dengan pendekatan kontekstual dapat meningkatkan kemampuan pemahaman konsep matematis pada segiempat dan segitiga.
