Research on mathematics learning is increasing and developing. However, empirical research ideas on working memory (WM) and creativity are still very limited. Educators must train students' WM skills in addition to providing reinforcement for mathematics learning. A systematic literature review follows the 10-step approach by Gough et al. The research questions consist of: What are the ideas about the definition, components and abilities of working memory? The idea of Working Memory in mathematics learning related to reasoning, problem solving and creativity? The researcher determined the publication period of the relatively latest articles in 2015 - 2024. The researcher conducted a database search on PsycInfo, MathEduc, Harzing's Publish or Perish and Scopus. Meanwhile, to determine the quality of the journal, the researcher based it on the database on ScimagoJR. After sorting, the articles analyzed were 37 found in 18 different journals. There are six definitions of WM, four related to working memory components, 10 related to working memory abilities, two related to working memory descriptions of reasoning and problem solving, three related to descriptions of creativity and three ideas of WM in mathematics learning, namely arithmetic, geometry and algebra.

Problem-solving is a crucial 21st-century skill that plays a vital role in mathematics education. One practical approach to developing this skill is through mathematical modelling, particularly by employing GeoGebra-assisted MEA learning. This study aims to: (1) evaluate the quality of GeoGebra-assisted MEA learning; (2) examine the influence of mathematical resilience on Mathematical Modelling Problem-Solving Ability (MMPSA); and (3) describe students’ MMPSA based on their levels of mathematical resilience. A mixed-methods approach was employed using a Sequential Explanatory design, with instruments including questionnaires, tests, observations, and interviews. The sample consisted of Class VII A as the experimental group and Class VII B as the control group, each comprising 30 students. Eight students were selected as qualitative subjects based on their mathematical resilience levels. The results indicate that GeoGebra-assisted MEA learning demonstrates high instructional quality and significantly enhances students’ MMPSA. Quantitative findings show that mathematical resilience has a significant effect, accounting for 30% of the variance in students’ problem-solving performance. These results are further supported by qualitative data obtained through observations and interviews. Students with high resilience tended to be confident, persistent, and effective in solving problems. Those with moderate resilience showed adequate capability but lacked precision, while students with low resilience were easily discouraged and exhibited low self-confidence. In conclusion, integrating quantitative and qualitative findings underscores the importance of fostering mathematical resilience to enhance students’ problem-solving abilities, particularly in the context of GeoGebra-assisted MEA in mathematical modelling.

Education plays a crucial role in developing high-quality human resources, and mathematics serves as a strategic discipline for strengthening logical, critical, and analytical thinking skills. One of the key competencies emphasized by the NCTM is mathematical problem-solving, which remains relatively low according to the 2022 PISA results. To address this issue, the GeoGebra-assisted Problem-Based Learning (PBL) model is applied because it fosters interactive and meaningful learning experiences. This study aims to analyze research trends and the implementation of mathematical problem-solving skills through the GeoGebra-assisted PBL model. This study employed a Systematic Literature Review (SLR) combined with bibliometric analysis using VOSviewer. A total of 200 articles were initially identified from the Google Scholar database through the Publish or Perish application (2021–2025); after applying inclusion and exclusion criteria and quality assessment procedures, 9 articles were selected for final synthesis and bibliometric mapping of keyword co-occurrence, network, and overlay visualizations. The analysis shows that the implementation of the GeoGebra-assisted PBL model consistently enhances students’ mathematical problem-solving skills. PBL cultivates critical thinking skills, while GeoGebra supports concrete visualization of mathematical concepts. The integration of both has proven effective and innovative in improving mathematics learning outcomes in the digital era.

Penelitian ini difokuskan untuk menganalisis kemampuan berpikir kreatif matematis siswa SMA dalam menyelesaikan masalah matematika. Metode yang digunakan adalah pendekatan kualitatif deskriptif dengan melibatkan 34 siswa kelas X di salah satu sekolah di Kabupaten Cirebon. Teknik pengumpulan data dilakukan melalui tes, observasi, dan wawancara. Data yang diperoleh dianalisis menggunakan reduksi data, penyajian data, dan penarikan kesimpulan. Temuan penelitian menunjukkan bahwa secara keseluruhan siswa berada pada kategori sedang yang memenuhi indikator kelancaran, orisinalitas, dan elaborasi. Hanya 1 siswa dengan kategori tinggi, 30 siswa kategori sedang, dan 3 siswa kategori rendah. Dominannya kategori sedang disebabkan oleh keterbatasan siswa dalam mengembangkan strategi penyelesaian alternatif. Indikator dengan rata rata tertinggi adalah kelancaran, sedangkan indikator terendah adalah fleksibilitas. Temuan ini menunjukkan bahwa siswa cukup mampu menghasilkan ide, tetapi masih kurang fleksibel dalam menggunakan strategi pemecahan masalah. Sehingga, Kemampuan ini perlu ditingkatkan agar siswa dapat memecahkan masalah dengan berbagai solusi dan memenuhi tuntutan pembelajaran abad ke 21. This study focused on analyzing the¬ mathematical creative thinking abilities of high school students in solving mathematical problems. The method used was a descriptive qualitative approach involving 34 grade 10 students in one of the schools in Cirebon Regency. Data collection techniques were carried out through tests, observations, and interviews. The data obtained were analyzed using data reduction, data presentation, and drawing conclusions. The research findings showed that overall students were in the medium category that met the indicators of fluency, originality, and elaboration. Only 1 student was in the high category, 30 students were in the medium category, and 3 students were in the low category. The dominance of the medium category was caused by students' limitations in developing alternative solution strategies. The indicator with the highest average was fluency, while the lowest indicator was flexibility. These findings indicate that students are quite capable of generating ideas, but still lack flexibility in using problem solving strategies. Therefore, this ability needs to be improved so that students can solve problems with various solutions and meet the demands of 21st century learning.
