Abstract:The results of the TIMSS survey, PISA, and the facts show that students' mathematical problem solving abilities are still low. This means that students have difficulty working on math problems, especially problem solving problems. Adversity Quotient (AQ) has an important role for students in solving learning problems. There are 3 AQs namely quitters, campers, and climbers. This study attempts to describe the profile of students' mathematical problem solving based on Polya's steps in terms of quitters, campers, and climbers. The result shows that quitters students cannot carry out the four steps of Polya problem solving well, namely understanding the problem, making problem planning, carrying out problem planning, and re-examining the process and results of the settlement. Campers students are not able to re-examine the results and processes that have been written. While climbers students can carry out all four steps in solving the intended Polya problem. Abstrak:Hasil survey TIMSS, PISA, dan fakta dilapangan menunjukkan kemampuan pemecahan masalah matematika siswa masih rendah. Artinya siswa mengalami kesulitan dalam mengerjakan soal matematika, khususnya soal pemecahan masalah. Adversity Quotient (AQ) memiliki peranan penting bagi siswa dalam memecahkan masalah belajar. Ada 3 AQ yaitu quitters, campers, dan climbers. Penelitian ini mencoba mendeskripsikan profil pemecahan masalah matematika siswa berdasarkan langkah-langkah Polya ditinjau dari quitters, campers, dan climbers. Artikel ini menunjukkan bahwa siswa quitters tidak dapat melaksanakan empat langkah-langkah pemecahan masalah Polya dengan baik yaitu memahami masalah, membuat perencanaan masalah, melaksanakan perencanaan masalah, serta memeriksa kembali proses dan hasil penyelesaian. Siswa campers tidak mampu melakukan pemeriksaan kembali terhadap hasil dan proses yang sudah ditulisnya. Sedangkan siswa climbers dapat melaksanakan seluruh empat langkah pemecahan masalah Polya yang dimaksud.

STEM-Based Digital Pocketbook: Development of Learning Media on Students' Mathematical Problem-Solving Skills AbstractThe 21st century needs a variety of learning media innovations that can be used as a device in implementing the curriculum. The goal of digital pocketbooks based on science, technology, engineering, and mathematics (STEM) is to develop into worthy and interesting learning media on mathematical problem-solving skills. The research method used Research and Development (R&D) using the ADDIE model. Data analysis techniques use qualitative and quantitative descriptive techniques. The process was conducted after validation of material experts and media experts who showed that STEM-based pocketbooks had interesting criteria to use. However, the effectiveness of digital pocketbook learning media cannot be carried out due to the covid-19 pandemic that resulted in learning activities being conducted online or online. The existence of this policy resulted in this research only being carried out to the stage of development or development.
The design of HOTS Ethnic-Mathematics is the stage that has been intended in this study. This type of research is research and development (Research and Development) by producing results in the form of Mathematics Higher Order Thinking Skill (HOTS) questions based on culture and local wisdom (Ethnic-Math HOTS). The development model referred to by the researcher is the Analysis, Design, Development, Implementation and Evaluation (ADDIE) which is adapted into Analysis, Design, and Development (ADD). The conclusion of this paper is Mathematical problem designs that are integrated with local culture and local wisdom can be developed into questions that have a function to measure students' high-level abilities. High-level abilities that can be measured using these questions are analytical skills, evaluation skills and creative abilities. By completing questions related to the culture in the area around students, students will be more challenged and motivated to do it. In addition, it will increase students' knowledge about the local culture in the area.
