The purpose of this research is to describe the ability of senior high school student in proposing LESTV problem. This research is quantitative descriptive research. The data collecting used in this research is through proposing problem in the area of LESTV material. The subjects participating in this research are 60 students of senior high school in the Surabaya Eastern. Based on the problem proposed by the students then it is classified into three groups namely, mathematical question, non-mathematical question, or statement. If the problem proposed is mathematical question, the analysis will be done by grouping the problem into the problem can be solved or can not be solved. Then, the problem can be solved will be classified based on the structure of syntax and semantics. The results show that in proposing the problem the subjects mostly can solve the problem, in proposing the problem tends to add new information and relevant to the problem. Based on the structure of semantics, it is found that the students can restate, classify, and compare and also modify the problem from information provided. Meanwhile, in terms of the structure of semantics, the students can propose the problem contains assignment, comparison, and use of additional information (new information). Keywords: Proposing problem; SPLDV; Syntax; Semantics.

Problem posing is a learning approach that trains students to be able to process and communicate mathematical problems based on information obtained. This study aims to describe the ability of high school students to pose problems on the topic of system of linear equations in two variables (SLETV). This study used a quantitative descriptive study involving 60 high school students in the East Surabaya area. The results showed that students were able to submit 60 problems, consisting of 54 problems can be categorized and 6 problems could not be categorized. Based on the semantic structure of mathematics, 17 students (31.48%) were able to pose problems using 1-relationship, 13 students (24.07%) were able to pose problems using 2-relationships, 13 students (24.07%) were able to raise problems using 3-relationships, and 11 students (20.37%) were able to pose problems using 4-relationships. Based on language structure (syntax), 13 students (24.07%) were able to pose problems using assignment propositions, as many as 17 students (31.48%) were able to pose problems using relationship propositions, and 14 students (25.93%) were able pose a problem using a presupposition proposition.

The development of the world of education in Indonesia can not be separated from the influence of globalization, science and technology are always growing rapidly give a comprehensive impact on all aspects of human life, including the sector of education. Resilient and competitive human resources are needed to meet these challenges. Thus, the need to know about Adversity Quotient of a person to know how far a person can survive and overcome the difficulty. Mathematics which is a universal science underlies the development of modern technology and has an important role in various disciplines. The development of problem-solving abilities is also one of the most important aspects in the objectives of mathematics learning, especially on sequence materials and arithmetic series. Arithmetic sequences and series became a very important mathematical concept because of its wide application, so widely used in daily life. So this qualitative research is done with the aim to describe the process of solving the problem of rows and arithmetic series of junior high school students based on Adversity Quotient climber category. Technique of data collection is done by giving of Problem Solving Task (TPM) sequence and arithmetic series and job-based interview. Based on the analysis of research data that has been done, it is concluded that climber students in understanding the problem trend to read the problem twice. In plotting problem solving, climber students have an alternative solution to solve a given problem. At the implementation stage, climber students solve existing problems based on the most appropriate appropriate problem-solving plan and clearly disclose the truth information from the solution of the problem that has been done. The process of re-examining the problem solving, it is clear that the climber's students are re-checking and also trying to find alternative ways to solve the problem by first making an illustration of the drawing before doing the calculation process.

Pelaksanaan program tersebutdilakukan dengan cara observasi, wawancara, dan dokumentasi dengan tujuan untuk mendapatkaninformasi yang akurat dan terciptanya solusi yang efektif terhadap segala permasalahan yangdihadapi oleh adik asuh. Hasil yang didapatkan, dampaknya sangat baik terhadap perubahan baikdari segi sikap dan motivasi. Adik asuh dapat kembali bersekolah melalui jalur PKBM, lebihberani untuk mengungkapkan pemikiranya, lebih berani tampil di depan khalayak umum, dan lebihtermotivasi untuk semakin giat belajar.

Berbagai kendala atau kesulitan dihadapi oleh guru selama proses pembelajaran secara daring, salah satunya adalah kendala pada perkembangan keterampilan komunikasi siswa. Keterampilan komunikasi matematis siswa perlu mendapatkan perhatian lebih selama pembelajaran daring dilaksanakan. Namun, berdasarkan wawancara dengan guru matematika kelas VII di SMP Negeri 50 Surabaya, kenyataan di lapangan menunjukkan bahwa selama proses pembelajaran daring, siswa kurang mampu menuliskan proses pemecahan masalah pada materi aljabar dengan baik. Sehingga, penelitian ini bertujuan untuk menganalisis kemampuan komunikasi matematis tulis siswa di SMP Negeri 50 Surabaya berdasarkan kemampuan matematika siswa selama pembelajaran daring. Teknik pengumpulan data dalam penelitian ini dilakukan melalui tes dan wawancara kepada siswa dengan kemampuan matematika tinggi, sedang, dan rendah. Adapun analisis data dilakukan dengan teknik analisis data deskriptif, meliputi reduksi data, penyajian data, dan penarikan kesimpulan. Berdasarkan hasil analisis data dan pembahasan, dapat ditarik kesimpulan bahwa siswa dengan kemampuan matematika tinggi memiliki kemampuan komunikasi matematis tulis yang baik, siswa dengan kemampuan matematis sedang memiliki kemampuan komunikasi matematis tulis yang cukup baik, dan siswa dengan kemampuan matematis rendah memiliki kemampuan komunikasi matematis tulis yang kurang baik.

63 students were involved in the study and elected Rizka as the subject of research. This is a case study aimed at describing the cause of Rizka's failure in solving ill-structured problems about the rectangle. The results showed that the subject was able to represent the problem with own language. Rizka failed to build a solution that corresponds to the problem due to partial mastery of the rectangular concept. Rizka uses trial and error because it fails to associate a problem with a square concept that is the key to problem-solving success. Rizka success in the justification process because the process is counting without giving meaning. Meanwhile, the monitoring and evaluation process carried out by Rizka has failed. Rizka confusion determines the final solution because the solution is built does not qualify the problem solution. This is where the Rizka fails to provide the final solution. In this case, teachers have a role to teach their students to build relationships between concepts that can be utilized in problem-solving.
