The present study aims at uncovering Mathematical Concept Understanding Ability in solving the problem of 3D Geometry from the perspective of both cognitive styles dependent and independent field. As the instrument, this study adopts Group Embedded Figure Test, Observation worksheet, test, interview, and documentation. In dealing with data analysis, it relies on qualitative analysis consisting data reduction, data display, and conclusion drawing. Based on the investigation, it could be inferred that the students with cognitive dependent field could solve the problem with 3D Geometry; however, they still need some improvements to realize a proper way in using such method. On the other hand, the students with cognitive independent field, they could correctly operationalize the 3D Geometry concept to solve the same problem. In addition, this study also recommends that to minimize the problem above, the teacher is supposed to give proportional distribution in implementing either individual or group task.

Spatial ability is an important one of the abilities for completing many tasks in everyday life successfully. Spatial ability is considered a type of different ability to others. Therefore, there needs a study on how are the characteristics of spatial abilities and to develop in schools. This paper is to reveal the ways are developing spatial abilities in learning mathematics. Based on literature review from some research, at least that there are six ways to develop spatial abilities in learning mathematics, namely: (1) using spatial language in daily interactions; (2) teaching for sketching and drawing; (3) using a suitable game; (4) using a tangram; (5) using video games; and (6) origami and folding paper. Playing video games like Tetris are exercises for spatial relations, mental rotation, spatial orientation, and spatial visualization.

The cognitive level between teachers and students is clearly different in problem-solving. In the mathematics context, especially the function problem was only in geometric expression form, for knowledge construction and student's learning should use their cognitive level capacity. Not only the solving process is based on that, but also learning should be efficient for all students, and analyzing those processes is the purpose of identification inefficient issues in this study. This investigative study was held on three respondents purposively selected from a science program of senior high school in West Jakarta, Indonesia. This study found that in the solving process, all students chose to construct an algebraic representation of the function by organizing concepts relevant to fragmented conceptualization. The process has held to apply each concept procedurally. There has been a resource and that is one concept of the domain of function, so the completion is an inefficient process because all three students were ignoring it to use. All three process for solving to the student’s academic culture, most common for emphasizing in learning related to the problem and their cognitive capacity.

Kurikulum pendidikan telah beberapa kali mengalami perubahan karena tuntutan perkembangan ilmu pengetahuan dan kebutuhan masa depan. Di setiap perubahan, siswa tetap dituntut untuk terus-menerus menggenerasi pengetahuan. Dalam pembelajaran, perkembangan ilmu pengetahuan dan teknologi telah meningkatkan peran siswa dan sekaligus mengurangi peran guru. Tulisan ini merangkum bagaimana proses belajar yang sampai dengan menggenerasi pengetahuan baru dan tetap menyesuaikan pada konteks perubahan. Belajar lebih baik jika melibatkan aspek kognitif dan metakognitif, serta mengoptimalisasi fungsi pikiran sadar dan bawah sadar. Berpikir, memfungsikan scaffolding, dan menerapkan pembelajaran yang mempersempit zone of proximal development (ZPD) adalah proses dalam rangka mendekatkan diri sampai sedekat mungkin dengan pengetahuan baru. Upaya itu disebut dengan keterlibatan. Berpikir termasuk bentuk keterlibatan dan status keberadaan, seperti: clarification, assessment, inference, dan strategies, untuk tujuan membentuk organisasi tubuh informasi melalui pemaknaan data dan kemudian memprosesnya ke dalam belief system sehingga menjadi pengetahuan.

Many studies related to the use of Augmented Reality (AR) in the learning process. However, not many researchers have studied the effect of using AR on affective and cognitive aspects in terms of education level. To uncover this problem, the researcher uses a systematic literature review (SLR) design. In this study, the SLR stage consisted of four stages (1) problem formulation; (2) literature search; (3) identification of the type of research; (4) information retrieval. The findings of this study reveal that the use of AR technology has an effect on cognitive and affective aspects at the elementary and high school education levels. Middle school is the level of education that mostly applies AR technology. This study provides a recommendation that AR technology can be a medium for learning mathematics that can be applied by teachers and students at the primary and secondary education levels.

The aim of this study is to describe profile of middle school students' mathematical literacy ability in Solving Number Pattern Problems. This study used a descriptive case study design with 29 students in grade VIII at a middle school in Kefamenanu city, Indonesia. Test and interviews were the methods to collect data about the mathematical literacy ability. To analysis data we used the Miles and Huberman models with stages namely reduction data, data presentation and conclusions as a technique. The results of the study concluded that the profile of middle school students' mathematical literacy ability in solving number pattern problems is in the high category. Students with high mathematical literacy abilities meet all indicators at 3 levels of mathematics literacy cognitive namely understanding level, implementation level and level reasoning. Students with medium mathematical literacy abilities were able to achieve indicators of the level of understanding, while for the level of application and reasoning not all indicators were achieved. Students with low mathematical literacy abilities are only able to reach the level of understanding indicators, while the level of application and level of reasoning has not been achieved.

Abstrak Beberapa penelitian terdahulu menunjukkan kemampuan pemahaman matematis khususnya dalam geometri masih rendah. Metode yang relevan diperlukan sebagai upaya meningkatkan kemampuan tersebut. Penelitian Quasi eksperimen dengan Static Group Comparison Design ini mempunyai tujuan untuk mengetahui dampak proses belajar menggunakan Auditory Intellectually Repetition (AIR) terhadap kemampuan pemahaman matematika siswa berkemampuan rendah. Subjek penelitian berjumlah 63 siswa kelas VII salah satu sekolah yang memiliki nilai Ujian Nasional (UN) matematika di bawah rerata nilai UN matematika di Indramayu, Jawa Barat. Dua kelas diambil dengan acak dari seluruh kelas VII, satu kelas mendapatkan pembelajaran dengan model AIR, sedangkan satu kelas yang lain mendapat pembelajaran konvensional. Instrumen berupa tes kemampuan pemahaman geometri berbentuk uraian. Berdasarkan penelitian ini model AIR berdampak secara signifikan pada kemampuan pemahaman geometri siswa berkemampuan rendah. Implikasi dari penelitian ini adalah siswa yang memiliki kemampuan rendah membutuhkan model pembelajaran yang tepat.Kata Kunci: model pembelajaran, Auditory Intellectually Repetition, pemahaman Geometri, siswa berkemampuan rendah.

The research aimed to optimize students’ mathematical solving abilities through the implementation of a didactic design developed based on lesson study activities on triangular number patterns. The research design used was didactical design research. Participants in the study were 10 students (12–15 years old) at a junior high school in Mataram, Indonesia. The researcher was the main instrument, with several additional instruments, one of which was the didactic hypothesis design. The data were analyzed using qualitative analysis. The research results revealed an increase in students’ mathematical problem-solving abilities during the implementation of didactic design on triangular number pattern material. However, the increase that occurred was less than optimal. This increase resulted from the didactic design encouraging students to use Quizizz, geoboards, and inspirational videos to solve problems. However, when watching inspirational videos and Quizizz, there were problems, such as an unstable internet connection, so activities that should have been done in groups were done collectively for one class.
