Kemampuan siswa menyelesaikan masalah perbandingan senilai berpengaruh pada kemampuan siswa pada konsep lainnya. Laporan Hasil Ujian Nasional menyebutkan bahwa kemampuan siswa menyelesaikan masalah perbandingan senilai masih rendah karena sebagian besar siswa hanya sekedar bisa mengerjakan perbandingan senilai dengan kalimat nominal sehingga ketika dikaitkan dengan permasalahan sehari-hari siswa kesulitan untuk menyelesaikannya. Seharusnya pembelajaran perbandingan senilai perlu memberikan kesempatan kepada siswa untuk mengkonstruksi pengetahuan mereka sendiri melalui sajian masalah yang bermakna dengan mempertimbangkan lintasan belajar siswa. Oleh karena itu, penelitian ini bertujuan untuk menghasilkan bahan ajar perbandingan senilai yang sesuai dengan lintasan belajar menggunakan pendekatan pendidikan matematika realistik untuk meningkatkan kemampuan penalaran matematis. Adapun lintasan belajar yang dihasilkan berangkat dari local instruction theory perbandingan senilai. Upaya untuk mencapai tujuan tersebut, penelitian ini menggunakan metode penelitian design research dengan desain penelitian model ADDIE. Tahapan yang dilakukan dalam penelitian ini meliputi 5 tahap yaitu tahap analysis, tahap design, tahap develop, tahap implementation¸ dan tahap evaluation. Partisipan dalam penelitian ini terdiri dari satu kelas uji coba yaitu kelas VII 4. Hasil pengolahan N-Gain menunjukan bahwa bahan ajar perbandingan senilai yang disusun sesuai lintasan belajar untuk meningkatkan kemampuan penalaran matematis dapat meningkatkan kemampuan penalaran matematis dengan nilai rata-rata sebesar 0,45 dengan kategori sedang. Mengacu pada KKM yang dimiliki oleh sekolah, maka kualitas peningkatan kemampuan penalaran matematis siswa sebesar 0,32.

Prospective mathematics teachers must have the characteristics of mathematical science, namely systematic, logical, and critical. This study aims to reveal the analysis of learning obstacles experienced by prospective mathematics teachers in number theory lectures with sub-material of division relations, FPB and KPK. This research uses a qualitative approach method in descriptive form. This research was conducted by collecting data through questionnaires and interviews and validated using the triangulation method. The study was limited to the analysis of ontogenic learning obstacles according to Brosseasu. The results of this study were that 4 out of 6 research subjects experienced the occurrence of ontogenic learning obstacles with details of 37.5% of prospective teacher students experiencing psychological ontogenic obstacles and instrumental ontogenic obstacles, then 25% experiencing didactic ontogenic obstacles. This indicates that students' readiness to take part in number theory courses is still weak. Students are weak in terms of psychological readiness, weak in readiness for complete mastery of related material previously studied and weak in terms of following the thought process needed in this course.

Junior high school students often have difficulties in understanding linear equations in one variable (LEOV). Therefore, this research aimed to enhance junior high school students' understanding of LEOV by developing and implementing effective learning activities. The research was conducted as design research in three stages: preliminary design, teaching experiment, and retrospective analysis. The participants of the research were 50 seventh-grade students from two junior high schools in Bandung, Indonesia. The data collected from observations, interviews, and student worksheets were analyzed using triangulation to ensure the validity and reliability of the research. The research explored how the teacher explained LEOV in four meetings and how they contributed to students’ understanding, where the first meeting dealt with open sentences, closed sentences, and the definition of LEOV from the context of distance and displacement, the second focused on solving LEOV from the context of two passing trains, and third focused on fractional LEOV from the context of jogging, and the fourth provided the students an opportunity to apply the LEOV concept from a dynamo-powered toy car simulation. The implication of the research is that teachers can significantly improve students' understanding of LEOV by implementing effective learning activities as identified here.

Number patterns are a fundamental aspect of mathematics, often serving as a bridge between arithmetic and algebra. Number patterns often require students to think abstractly, identifying relationships and rules that govern the sequence of numbers. For some people, this transition from concrete to abstract thinking can be difficult. Encouraging students to visualize patterns using concrete objects or images can help bridge this gap, making abstract concepts more real. The aim of this study was to investigate the students' difficulties and how grade 9 students' mathematics approaches to number pattern problems. 32 students from a junior high schools in Tangerang participated in this case study. Purposive sampling technique is used in this study. The stages of the preliminary study involve interviewing the mathematics teacher regarding learning, administering preliminary exams, and evaluating the outcomes of the preliminary exams. Research data was collected through tests and interviews. These interviews took place post the analysis of initial test (a diagnostic tests). The result showed that the difficulty in discerning the regularity of the numerical arrangement: 1) In calculating the formula for the nth term in a number pattern, modeling is used; 2) Students frequently employ the direct proportion method to generalize patterns without taking into account the overall arrangement of numbers; 3) Observing the arrangement of numbers causes uncertainty in seeing order; 4) In generalizing number patterns, damage occurs; 5) illustrating that number patterns always have regularities, and these regularities are not always in the form of numerical differences.Pola bilangan adalah aspek mendasar dari ilmu matematika dan sering kali dianggap sebagai jembatan antara aritmatika dan aljabar. Pola bilangan mengharuskan siswa untuk berpikir abstrak, mengidentifikasi hubungan dan aturan yang mengatur barisan bilangan. Bagi sebagian orang, transisi dari pemikiran konkrit ke abstrak bisa jadi sulit. Mendorong siswa untuk memvisualisasikan pola menggunakan objek atau gambar konkret dapat membantu menjembatani kesenjangan ini, menjadikan konsep abstrak menjadi lebih nyata. Tujuan dari penelitian ini adalah untuk menyelidiki kesulitan siswa terhadap masalah pola bilangan pada siswa kelas 9. Adapun subjek dalam penelitian studi kasus ini adalah 32 orang siswa SMP di Tangerang. Teknik pengambilan sampel adalah dengan menggunakan teknik purposive sampling. Tahapan studi pendahuluan meliputi wawancara kepada guru matematika mengenai pembelajaran, pelaksanaan tes awal, dan evaluasi hasil ujian. Data penelitian dikumpulkan melalui tes dan wawancara. Wawancara ini dilakukan pasca analisis tes awal (tes diagnostik). Hasil penelitian menunjukkan bahwa kesulitan dalam membedakan keteraturan susunan bilangan: 1) Menggunakan pemodelan dalam menghitung rumus suku ke-n suatu pola bilangan; 2) Siswa sering menggunakan metode perbandingan langsung untuk menggeneralisasi pola tanpa memperhitungkan susunan bilangan secara keseluruhan; 3) Mengamati susunan bilangan menimbulkan ketidakpastian dalam melihat keteraturan; 4) Dalam menggeneralisasi pola bilangan, terjadi ketidaksesuaian; 5) menggambarkan bahwa pola bilangan selalu mempunyai keteraturan, dan keteraturan tersebut tidak selalu berupa perbedaan angka.

Research on relational thinking has been widely conducted; however, no analysis of these studies has been carried out so far. This research aims to analyze the distribution of research related to relational thinking in mathematics at elementary and high school levels, which was conducted from 2016 to April 2024. This study employs the Systematic Literature Review (SLR) method, focusing on articles indexed in Scopus, ERIC, ScienceDirect, and Google Scholar. The results of the Systematic Literature Review (SLR) show that: (1) there were 30 studies on relational thinking ability in mathematics conducted; (2) eight studies were conducted abroad, while 22 were conducted in Indonesia; (3) arithmetic was the most common topic in research on relational thinking; (4) the majority of studies on relational thinking ability have been carried out at the junior high school level; (5) of the 30 articles, 14 are indexed in Sinta, 7 in Scopus, and 9 are indexed only in Google Scholar; (6) there are two definitions of relational thinking used by researchers. These findings serve as a basis for determining future research topics related to relational thinking ability.

This study identifies and describes the types of learning obstacles and the factors that cause them in seventh-grade students learning quadrilateral material. The qualitative method used in this research focuses on teaching barriers experienced by students at SMPN 2 Sampit. Data were collected through observation, interviews, written tests, analysis of student answers, and documentation. The results of the study showed that students faced three main types of obstacles, namely ontogeny obstacle (mental readiness, lack of motivation and enthusiasm), didactical obstacle (classical way of teaching and without involving students, less than optimal use of teaching materials using only LKS), and epistemology obstacle (limited context and also low mastery of material owned by students)
