Geometry is one of the content of mathematics which in many studies is associated with students' thinking abilities, such as critical thinking and reasoning abilities or others..This study aims to conduct a systematic review of the geometry research in school for identifying the types of mathematical thinking and their interconnections. We searched the Scopus database for articles published from 2003 to 2023 using relevant keywords. We applied the PRISMA method to select and evaluate the studies or articles based on the empirical data. We retrieved and evaluated data from the studies on the various styles of mathematical thinking evolved. Out of 166 titles that were initially obtained, only 10 titles passed the five stages of the systematic review protocol process. We identified 10 types of mathematical thinking that were discussed in the context of learning geometry at school: Creative Mathematical Reasoning (CMR), Computational thinking, Geometric reasoning, Geometric thinking van hiele theory, Geometric thinking (3D geometric thinking with representations), 3D geometry thinking, Visuo spatial reasoning, Geometry Spatial Reasoning, mathematical creative reasoning (MCR), and Inductive reasoning. We also found some connections of literature between these types of mathematical thinking, such as CMR and MCR, Geometric reasoning and Geometric thinking, and Visuo spatial reasoning and Geometry Spatial Reasoning. This systematic review provides an overview of the current state of research on geometry and reasoning in school mathematics and reveals some gaps and directions for future study. It also has implications for teachers who want to enhance their students’ mathematical thinking skills in geometry by exposing them to different types of mathematical thinking and their connections.

Spatial thinking is important in learning Science, Technology, Engineering, and Mathematics. Numerous studies about spatial ability in various fields like mathematics, neuroscience and phycologist considered various factors such as gender, age, or demography. However, a few studies are still about enhancing spatial ability in the context of mediated pedagogies. This study aims to describe spatial research on mathematics education, especially related to the intervention or learning design of spatial reasoning. A bibliometric study is employed to determine the research trend of spatial reasoning, especially related to teaching practice. The review follows a structured design consisting of several stages of the PRISMA method. From 652 documents about spatial in mathematics education gathered from the Scopus data, it is reduced to 40 documents regarding spatial reasoning in mathematics education. Further, only 19 documents about intervention and practice in enhancing spatial reasoning exist. This study may benefit researchers in mathematics education by showing the development and trend of spatial reasoning research and suggesting new directions for future research.

This study aims to describe the relational thinking profile of students with field independent and field dependent cognitive styles in solving contextual problems. There are seven study groups in class VII MTsN 1 Surabaya City and two male students from class VIIA totaling 40 students were selected as subjects based on the results of the GEFT cognitive style test and equivalent mathematical ability. Students who got a GEFT score ≤ 9 were classified as field dependent (SFD) and field independent (SFI) got a score > 9. Subjects with field independent cognitive style (SFI) were selected with a score of 11, subjects with field dependent cognitive style (SFD) with a score of 7 with TKM results, namely 77 and 82. Data collection techniques in this study used TPM and interviews. Data analysis was carried out by means of data reduction, presentation and conclusion drawing. Valid data obtained through time triangulation. The results showed that in understanding the problem, (1) SFI and FFD students found important elements in a given problem. Learners SFI describes the relationship between the elements in the problem while students SFD can not explain. Learners FI and FD build relationships in determining the completion planning strategy and checking again using arithmetic operations and carrying out the plan made. Learners FI solves the problem using another method while learners FD uses the usual way. Learners FI do the recalculation while students SFD counts back by way of substitution.

Mathematical proof demands accuracy and precision in formulating correct and logical arguments. Students need to develop their ability to produce accurate and precise proofs. This study aims to analyze the ability of prospective mathematics teachers in constructing geometry and algebraic proofs. The research subjects were 8 prospective mathematics teacher students, four male and four female. This descriptive qualitative research begins with giving tests to research subjects, then we conduct interviews. The results showed that male students were better at compiling geometry proofs than compiling algebraic proofs. While female students are better at compiling algebraic proofs than geometry. This is due to the spatial ability of men better than women.Â When compiling geometry proofs apply procedural proofs, syntactic proofs, and semantic proofs. When compiling algebraic proofs only apply procedural proofs. Female students when compiling geometry proofs only apply procedural proofs. When compiling algebraic proofs, they apply procedural proofs and syntactic proofs.

Monyet merupakan salah satu jenis mamalia primata yang termasuk dalam sub-ordo Anthropoide. Beberapa spesies monyet telah mengalami penurunan jumlah secara signifikan pada beberapa dekade terakhir, oleh karena itu diperlukan suatu metode untuk mendeteksi keberadaan populasi monyet di suatu wilayah sebagai upaya untuk meningkatkan konservasi monyet agar terhindar dari ancaman kepunahan. Diketahui bahwa sebagian besar habitat monyet adalah hutan yang merupakan alam bebas dengan memiliki banyak pohon dan berbagai satwa lain di dalamnya, hal ini mengakibatkan keterbatasan untuk mendeteksi populasi monyet di suatu wilayah. Dalam komunikasi vokal, monyet mengeluarkan berbagai jenis suara, dimana suara yang dikeluarkan oleh monyet dari jenis yang berbeda dapat menghasilkan sinyal suara yang berbeda, sehingga memunculkan suatu karakteristik. Dari informasi karakteristik tersebutlah pada penelitian ini akan dilakukan klasifikasi jenis monyet berdasarkan suara dengan menerapkan metode dimensi fraktal Higuchi dan klasifikasi K-Nearest Neighbor (K-NN). Tahapannya yaitu pre-processing data, kemudian ekstraksi ciri dengan dekomposisi suara hingga level 7 menggunakan Discrete Wavelet Transform (DWT) berjenis mother wavelet Daubechies db4. Selanjutnya melakukan perhitungan nilai Higuchi. Dari nilai Higuchi yang telah didapat, dilakukan tahap klasifikasi K-NN. Pada penelitian ini menggunakan rasio pembagian data menjadi data training dan data testing sebesar 0,5 : 0,5, pada Kmax = 50 dan k = 3 didapatkan hasil akurasi tertinggi yaitu sebesar 90,38%. Dari hasil akurasi yang tinggi disimpulkan bahwa metode Higuchi dan K-NN dapat diterapkan pada klasifikasi jenis monyet berdasarkan suara. Kata Kunci: Monyet, Dimensi Fraktal Higuchi, K-Nearest Neighbor (K-NN).

Ikan adalah kelompok hewan bertulang belakang (vertebrata) yang hidup di dalam air, bernapas melalui insang, dan memiliki sirip untuk berenang. Dalam taksonomi, ikan masuk dalam kelompok paraphyletic. Ikan berperan penting dalam ekosistem perairan dan juga menjadi makanan pokok bagi banyak masyarakat di muka bumi ini. Selain dilihat dari bentuk tubuh, ekor, dan bentuk siripnya, corak pada tubuh ikan juga berperan penting dalam mengidentifikasi jenis ikan. Dalam matematika, gagasan mengenai fraktal adalah salah satu metode yang cocok untuk memahami pola atau bentuk yang tidak beraturan pada suatu objek. Dalam penelitian ini, dilakukan pengklasifikasian ikan laut berdasarkan corak pada tubuhnya menggunakan dimensi fraktal. Sebanyak 120 citra berwarna pada bagian tengah tubuh ikan laut digunakan untuk diubah ke dalam citra grayscale lalu dilakukan segmentasi pada corak tubuhnya. Daerah hasil segmentasi tersebut digunakan untuk mengetahui pola corak tubuh ikan menggunakan deteksi tepi Canny. Hasil nilai dimensi menggunakan box counting diklasifikasikan menggunakan metode K-Means Clustering dengan 8 klaster yang memiliki nilai akurasi sebesar 90%. Kata Kunci: Corak Tubuh Ikan Laut, Box Counting, K-Means.
