Penelitian ini bertujuan untuk mendeskripsikan secara jelas bagaimana rangkuman laporan hasil-hasil penelitian tentang kesulitan belajar siswa pada pelajaran matematika di sekolah dan bentuk kesulitan yang dominan bagi siswa mempelajari matematika dalam enam tahun terakhir. Metode yang digunakan adalah metode deskriptif, yaitu menganalisis gejala yang ada berdasarkan data yang sudah diperoleh dari berbagai penelitan sebelumnya dan dirangkum dengan pendekatan meta-ethnography. Objek penelitiannya adalah laporan hasil-hasil penelitian guru maupun alumni mahasiswa pendidikan matematika yang memuat masalah kesulitan belajar matematika. Hasil rangkuman menunjukkan bentuk-bentuk kesulitan siswa adalah kesulitan representasi matematis pada materi tertentu atau merepresentasikan informasi dari soal cerita ke dalam kalimat matematika; kesulitan memahami definisi, menerapkan konsep, prinsip, dan algoritma; kesulitan menentukan hubungan dua garis dan menentukan sudut yang terbentuk dalam geometri; kesulitan aspek pengetahuan, pemahaman, dan penerapan soal cerita; kesulitan pemahaman konseptual materi tertentu, tidak memahami hubungan antar konsep, dan tidak memahami arti simbol; kesulitan koneksi matematis dalam menyelesaikan soal operasi hitung aljabar; dan kesulitan dalam menyimpulkan hasil penyelesaian soal.

This study aims to find out students' relational understanding linear program materials in the class XI MAN 2 Pontianak . This form of quantitative descriptive research, for the data collection techniques used are test techniques and indirect communication techniques. For the data-mining techniques used is a matter of tests and interviews. Student relational understanding in this study is measured using linear program material consisting of 6 essay questions. The relational understanding referred to in this study is the students' ability to solve the linear program problem by using appropriate procedures and knowing why it is used. It is known that students who have the relational understanding ability to solve a problem is that students have the prerequisite ability to solve linear programs that fall into a very good category, to be able to do overall procedures in ending linear programs in excellent categories, and to get the right results and provide logical reasons for completing linear programs. Overall students have a high relational understanding with very good percentages. Keywords: Relational Understanding, Conceptual Understanding and Procedural Understanding, Linear Program

This study aims to determine numeracy literacy in the material equations and inequalities of the absolute value assessed from the emotional intelligence of students at SMA Panca Setya Sintang. The method used in this research is descriptive with a case study research. The subjects in this study were students of grade X IPA 3 with a total of 17 students. The object to be researched is numeracy literacy in the material equations and inequality of the absolute linear value of one variable assessed from the emotional intelligence of students. The techniques used in data collection are questionnaires, numeracy literacy tests and interviews. The results obtained from this study that there were four students who had high levels of emotional intelligence and tended to have high numeracy literacy, eleven students had moderate emotional intelligence and also varied numeracy literacy with one student with good numeracy literacy, six students with good numeracy and four students with poor numeracy, and two students who had low levels of emotional intelligence and had low numeracy literacy. Keywords: Numeracy Literacy, Emotional Intelligence, Equations And Inequalities Of The Absolute Value

There are facts obtained through interviews and observations of students' answers that the VII grade students of SMP LKIA Pontianak are suspected of having misconceptions. Based on theses facts, the purpose of this research is to reveal the form of misconception based on Mason stages and the causes of the misconception. The subjects involved in this research were fifteen students. This research is a case study research with a descriptive method. Data collection tools used modified CRI diagnostic tests and interviews. Based on data analysis, the misconceptions experienced by students in completing set operations consisted of notation misconceptions, generalization and specialization. Researchers found out of the three forms of misconception, the most common is notation misconception. In the problem solving stage according to Mason consists of three stages, namely  entry, attack, and review, students who experience misconceptions in two stages, namely at the entry stage, students experience notation misconceptions and at the review stage, students experience misconceptions of notation, generalization, and specialization. Researchers found the causes of misconceptions consisted of three factors, namely students' associative thinking, incomplete / wrong reasoning, and wrong intuition. Researchers found out of the three forms of misconception, the most common is wrong intuition.            Keyword: Causes of Misconceptions, Mason Stages, Misconceptions

Based on the pre research at SMA Taruna Bumi Khatulistiwa, there was only 6 of 32 overall students categorized as active in mathematics class and the percentage of the number of students who passed the grade in trigonometry was only 59,37%. The solution for the problem above is try to apply problem posing approach in the class. The aim of this research is to explore the effectivity of problem posing approach in Sines and Cosines Rule at class X SMA Taruna Bumi Khatulistiwa. The research method used in this research is experimental method in the form of pre-experimental design. Based on the result of the research, learning implementation was categorized as good with the average score is 3.48. Students learning activity was categorized as active with the average percentage is 75.58%. Students learning passion grade was not classically satisfied with the percentage is 36% based to the number of students who successfully pased the passing grade. Lastly, students responds to learning process with the approach is considered positive with the percentage is 92.86%. It can be concluded that learning implementation with problem posing approach in Sines and Cosines Rule at class X SMA Taruna Bumi Khatulistiwa was not effective.Keywords: Effectivity, Problem Posing Approach, Sines Rule, dan Cosines Rule
