This study aims to analyze the impact of mathematics learning using Computational Thinking (CT) integration and to enlighten educators, researchers, and policy makers on the tactics, benefits, and challenges involved in incorporating CT into mathematics education by synthesizing existing research and educational initiatives. Using the systematic literature review (SLR) method with a qualitative approach, the results of this research were in the form of descriptive analysis. The database used was Scopus to filter relevant material about CT and mathematics education. Based on the search, nine publications from 2019 – 2023 were selected systematically based on the PRISMA protocol. This study's results indicated a relationship between CT and several students' mathematical abilities, such as problem-solving and improving problem-solving skills. Not only can it improve the cognitive side of students, but CT can also improve students' affective side, such as increasing creativity, confidence, and involvement in the learning process. The impact felt is not only in the micro scope (in the classroom), but can also be macro. CT can improve the quality of higher learning, so CT research can be used to determine a country's curriculum.

In the last decade, augmented reality has been one type of virtual reality technology. AR can be applied to mobile learning, improving efficiency and effectiveness in education, even for learning mathematics. The study aims to analyze and describe comprehensively the effect of experiential learning and direct instruction assisted by augmented reality on the acquisition and improvement of students' mathematical reasoning abilities. This research uses quantitative methods with a quasi-experimental, one-group pretest-posttest design and a pretest-posttest control group design. The sample in this study consisted of 50 students in the eighth grade at one of the secondary schools in Bandung, Indonesia. The instrument in this study is a set of mathematical reasoning ability tests. The results of this study concluded that 1) Based on the standard of the deviation, the descriptive spread of scores for achieving mathematical reasoning abilities of students learning with experiential learning assisted by augmented reality (more widespread); 2) Cohen's d value on the output paired samples effect sizes was 14.003 with a point estimate of (large) so the value of the effects sizes obtained shows that the implementation of experiential learning assisted augmented reality has a major effect on the acquisition of mathematical reasoning abilities; 3) The mean achievement of mathematical reasoning abilities of students studying with experiential learning assisted by augmented reality was 60.38 relatively lower than the mean achieving mathematics reasoning abilities of students who studied with directed instructions assisted by augmented reality, 70.33; 4) The effect size value shown by the value is -3.50, and this value is less than 0.2, so based on Cohen's d criterion, then the effect of experiential learning assisted by augmented reality on the acquisition of mathematical reasoning abilities students are in the small category. The findings combine experiential learning and directed instructions assisted by augmented reality, influencing students' reasoning ability mathematically.

Reversible thinking is a mathematical competency that influences students' success in solving problems. Problem-solving is the core of mathematics education. This research aims to identify the characteristics of students' thinking in solving problems that require reversible thinking ability. A qualitative method with a case study approach was used in this research. The study used tests and interviews on 44 eighth-grade students in West Java, Indonesia. In-depth interviews were conducted with representative students whose answers were representative of the other students. All students' answers were analyzed using the thematic analysis software ATLAS.ti. According to the characteristic indicators of reversible thinking. This study found that junior high school students' ability in reversible thinking is not optimal. Some students who successfully solve problems are limited to using backward thinking processes rather than invertible ones. The other students still have difficulties constructing answers due to the limited context when students first learn the concept (problems with forward-thinking). Thus, this ability needs to be understood by students as one factor that supports the success of the problem-solving process.

Representational transformation skills significantly influence students' success in problem-solving. Students who struggle with representational transformation skills are often less adept at utilizing mathematical ideas and relationships, and vice versa. Therefore, this study used a qualitative, descriptive-interpretive approach to examine students' semiotic representation skills when solving mathematical problems. The research was conducted in a Year 9 classroom in a public school in Bandung, Indonesia, with 30 participants divided into high, middle, and low-ability groups based on their level of mathematical ability. Data was collected using both test and interview techniques. The results indicated that students in the high and middle ability groups had adequate skills in algebraic treatment and conversion from algebra to geometry and verbal expression skills for constructing algebraic expressions and converting verbal statements into mathematical equations. In contrast, the low-ability group demonstrated a lack of semiotic representation skills in problem-solving. These findings highlight the importance of transformation and conversion skills in mathematical problem-solving activities and can be valuable information for teachers and observers of mathematics education.

Penelitian ini bertujuan untuk menganalisis kemampuan Computational Thinking (CT) siswa SMP dalam menyelesaikan soal matematika pada materi deret aritmetika ditinjau dari Kemampuan Awal Matematis (KAM). Penelitian ini menggunakan pendekatan deskriptif kualitatif dengan subjek siswa kelas VIII yang dipilih berdasarkan kategori KAM tinggi, sedang, dan rendah. Instrumen penelitian terdiri dari tes uraian dan pedoman wawancara. Hasil penelitian menunjukkan bahwa siswa dengan KAM tinggi mampu memenuhi seluruh indikator CT, yaitu decomposition, pattern recognition, abstraCTion, dan algorithm. Siswa dengan KAM sedang hanya mampu memenuhi sebagian indikator, sedangkan siswa dengan KAM rendah cenderung hanya memenuhi dua indikator awal. Temuan ini diperkuat oleh hasil wawancara yang menunjukkan bahwa siswa dengan KAM rendah mengalami kesulitan dalam menyusun strategi penyelesaian yang sistematis. Penelitian ini menyimpulkan bahwa KAM berperan penting dalam mendukung kemampuan CT siswa, sehingga diperlukan pendekatan pembelajaran yang adaptif dan kontekstual. This study aims to analyze the Computational Thinking (CT) skills of junior high school students in solving arithmetic sequence problems based on their prior mathematical ability (KAM). A descriptive qualitative approach was employed, involving grade VIII students categorized into high, medium, and low KAM levels. Research instruments included problem-solving tests and interview guidelines. The findings indicate that students with high KAM were able to meet all CT indicators: decomposition, pattern recognition, abstraction, and algorithm. Students with medium KAM demonstrated partial mastery, while those with low KAM mostly fulfilled only the first two indicators. Interview results confirmed that low-KAM students had difficulty constructing systematic problem-solving strategies. The study concludes that prior mathematical ability plays a significant role in supporting students' CT skills, thus emphasizing the need for adaptive and contextual learning approaches.

Penelitian ini bertujuan untuk mengkaji tren penelitian pendidikan mengenai kemampuan representasi matematis yang dipublikasikan dalam jurnal-jurnal pendidikan matematika di Indonesia pada periode 2014 sampai 2022. Dengan menggunakan pendekatan analisis isi kualitatif, penelitian ini menelaah berbagai pola yang meliputi desain penelitian, jenjang pendidikan subjek penelitian, topik matematika yang dikaji, teknik analisis data yang digunakan, pemanfaatan teknologi dalam pembelajaran, serta keterkaitannya dengan Tujuan Pembangunan Berkelanjutan (Sustainable Development Goals / SDGs). Hasil kajian menunjukkan bahwa jumlah publikasi mengalami perkembangan yang tidak stabil, dengan peningkatan yang cukup signifikan pada tahun 2018 setelah terjadi penurunan tajam pada tahun 2017. Dari sisi metodologi, desain penelitian kuantitatif masih sangat mendominasi, khususnya penelitian yang menggunakan statistik deskriptif dan metode inferensial dasar, seperti uji t dan ANOVA. Ditinjau dari subjek penelitian, peserta didik tingkat sekolah menengah pertama merupakan kelompok yang paling sering dijadikan objek kajian. Sementara itu, materi geometri menjadi topik yang paling banyak diteliti, sedangkan domain bilangan masih relatif jarang mendapatkan perhatian. Dalam aspek pemanfaatan teknologi, sebagian besar penelitian belum mengintegrasikan teknologi secara eksplisit dalam proses pembelajaran, meskipun terdapat peningkatan yang cukup terlihat pada masa pandemi COVID-19. Selain itu, meskipun sebagian besar penelitian secara tidak langsung mendukung pencapaian SDG 4 tentang pendidikan berkualitas, keterkaitan secara eksplisit dengan kerangka keberlanjutan global masih sangat terbatas. Berdasarkan temuan tersebut, penelitian ini menegaskan pentingnya pengembangan kajian selanjutnya yang lebih beragam dari sisi metodologi, lebih luas dalam cakupan materi matematika, serta lebih terarah dalam mengaitkan penelitian pendidikan matematika dengan agenda pendidikan global dan pembangunan berkelanjutan.

The limited availability of valid and reliable numeracy literacy test instruments, particularly in the algebra domain, for junior high school students in preparation for the Minimum Competency Assessment exam makes this research important to conduct. This study aims to describe the quality of a numeracy literacy test instrument in the algebra domain for junior high school students. It is a quantitative study with a descriptive approach. This method is used to describe the quality of the numeracy literacy test instrument in the algebra domain, which was developed based on Rasch modeling. The research procedure comprises three main phases: item development, limited trial testing with 8th-grade students, and item quality analysis using the Rasch model analysis with the Winsteps software. The developed numeracy literacy test instrument consists of 12 essay questions. The instrument was then used to collect quantitative data from 34 8th-grade students selected as research respondents through purposive sampling. The results indicate that one item is categorized as invalid (requiring revision), while the remaining items are deemed valid. The reliability index is 0.80, which falls into the ideal category. The analysis of item difficulty levels reveals that one item is categorized as difficult, nine items as moderate, and two items as easy. Overall, the developed algebra numeracy literacy instrument meets the criteria of Rasch modelling, although one item requires revision. Teachers can use this instrument as an assessment tool to evaluate students' algebraic numeracy literacy skills in junior high school. This instrument can also serve as a model for developing numeracy literacy test instruments in other domains.
