Penalaran spasial adalah kemampuan mental yang bersangkutan dengan pemahaman, memanipulasi, merotasi, dan hubungan visual. Penalaran spasial yang terdiri dari tiga konstruk yakni visualisasi spasial, rotasi mental, dan orientasi spasial ini merupakan salah satu kemampuan penting dalam geometri. Penelitian deskriptif kualitatif ini bertujuan mendeskripsikan kemampuan spasial siswa SMPN1 Padangpanjang dalam memahami, memanipulasi dan merotasi suatu objek serta kemampuan membayangkan bentuk objek dari perspektif berbeda dengan pemberian tes masalah geometri dengan topik dimensi tiga. Subjek dalam penelitian ini adalah 32 orang siswa SMPN1 Padangpanjang. Subjek kemudian dikategorikan menjadi kelompok tinggi, sedang, rendah dan dilakukan pendalaman pada tiap perwakilan kelompok melalui wawancara. Berdasarkan aktivitas penalaran spasial dan wawancara, diperoleh deskripsi sebagai berikut: siswa kelompok tinggi sebanyak 18,75% siswa, memiliki kemampuan penalaran spasial yang tinggi karena mampu memunculkan mental images yang jelas untuk menyelesaikan masalah geometri dengan langkah terstruktur, siswa kelompok sedang sebanyak 56,25% siswa memiliki kemampuan penalaran spasial yang sedang karena menemukan jawaban dengan cara yang tidak terstruktur dengan menebak jawaban, lalu membayangkan untuk mengecek kebenaran jawaban, sedangkan siswa kelompok rendah sebanyak 25% siswa memiliki kemampuan penalaran spasial yang rendah karena sama sekali tidak mampu memperoleh gambaran visual dalam pikirannya dan tidak tahu cara menyelesaikan masalah yang diberikan.

A good learning tool is one of the important things to make. This is because the support of learning devices also affects the achievement of a directed learning process so that mathematics learning is also achieved, such as solving mathematical problems. The ability to solve mathematical problems is expected to develop well in each student. Based on this, it is necessary to develop guided discovery-based learning tools to improve students' problem-solving skills. The research was conducted with the aim of knowing the characteristics of guided discovery-based learning that are valid, practical and effective to improve the problem-solving abilities of eighth grade students of SMP/MTs. This type of research is using the Plomp model, which consists of three stages, namely the preliminary stage, the prototype stage and the assessment stage. The instruments in this study were validation sheets, observation sheets, questionnaires, interviews and tests. The results showed that the learning tools in the form of RPP and LKPD based on guided discovery for class VIII SMP/MTs were valid, practical, and effective. The validity of the RPP reached 79% and LKPD 80.2%. While the practicality of the lesson plans is 77.6% and LKPD 90.5%. In addition, the effectiveness of the two products to improve problem solving skills is 83.87%.

Mathematics learning outcomes can be said to be successful if someone is able to recognize and master mathematics subject matter in learning activities. However, in reality, learning mathematics often results in low learning outcomes. Students at SMP Negeri 1 Kabun can also suffer from low mathematics learning outcomes. Regarding this problem, the solution offered in this research is the Two Stay Two Stay (TSTS) learning model. In this research, the aim is to convey mathematics learning outcomes by comparing students who implemented it using the TSTS learning model and students who implemented it using the direct learning model at SMP Negeri 1 Kabun. In this research, using a quasi-experiment as a type of research by choosing a nonequivalent posttest only control group design as the research design. To conduct this research, Class IX of SMP Negeri 1 Kabun became the population using the Purposive Sampling technique for sampling. Class IX-4 was selected as the experimental group and Class IX-3 was selected as the control group. Minitab software was used to analyze the final test results. The results obtained with a P-value <0.05 indicate that students at SMP Negeri 1 Kabun who apply TSTS learning get superior mathematics learning outcomes compared to students who apply direct learning. Therefore, there is a significant difference in mathematics learning outcomes between students at SMP Negeri 1 Kabun who take TSTS learning and those who take direct learning.Keywords – Two Stay Two Stray, Learning Outcomes

Mathematical ability is a crucial aspect of modern life as it influences various fields such as economics, technology, and science. This study, spanning 2014-2023, examines articles on mathematical ability in leading journals. Using the bibliometric methods, it includes article searches in Scopus and Google Scholar via Publish or Perish (PoP), classification for bibliometric analysis, metadata checks, and bibliometric analysis using VOSviewer. The research shows a consistent trend in publications on mathematical ability, with minimal fluctuations and significant citation patterns. High-citation articles underscore the field’s importance in knowledge advancement. Key terms are ‘ability’, ‘mathematical ability’, and ‘student’, indicating research focus areas. However, limited author collaboration suggests potential for increased interdisciplinary synergy and knowledge sharing. These findings highlight opportunities for enhancing cross-disciplinary collaborations and research networks. They offer insights for policymakers, educators, and researchers in understanding trends, developing effective learning strategies, and encouraging further research in mathematical ability. In summary, this bibliometric study provides a comprehensive overview of the significance of mathematical ability in research, emphasizing the need for collaborative, innovative educational and research practices. It underscores the importance of further research to deepen understanding and application of mathematical ability, promoting an integrative approach in this essential field.

Mathematics communication ability is an essential component of mathematics that students should have. However, the mathematics communication ability of students, especially in Indonesia, still needs to improve. This study offers a new and different view of mathematics communication to improve it. This study aims to develop an assessment tool for students’ mathematics communication to identify the problems so teachers can focus on improving those areas. Not only the cognitive domain of the students, but this study also includes assessments of the affective and psychomotor domains as well. The reason is that cognitive, affective, and psychomotor aspects are interconnected in mathematics communication. The study of these three domains is called behavior. The assessment tools consist of the mathematics communication behavior analytical rubric and appropriate mathematics test problems. This study is developmental research with three phases: the development of the analytical rubric, the development of mathematics tests, and the application. The participants in this study are two mathematics education experts and 240 students in the 8th grade from seven schools, each located in a different city. The findings of this research show that the developed assessment tools can be used to assess students’ mathematics communication behavior.
