The implementation of Indonesia's Merdeka Curriculum necessitates a comprehensive understanding of student characteristics to support personalized learning experiences. This study explores the evaluation of student characteristics, assessment instruments, and their application in improving the learning process within the Merdeka Curriculum framework.To examine the evaluation of student characteristics, various assessment instruments, factors influencing instrument selection and application, and the benefits of evaluations in enhancing the learning process. This qualitative study employs a systematic literature review. The research steps include: 1) Collecting relevant literature from academic databases, focusing on journal articles, books, and government regulations related to the Merdeka Curriculum and student assessment; 2) Analyzing collected materials using content analysis techniques; 3) Synthesizing key themes and findings; 4) Validating results through data source triangulation and peer review. The study identifies key student characteristics for assessment, including cognitive abilities, learning readiness, motivation, learning styles, self-regulation, and social-emotional skills. Various assessment instruments are discussed, such as standardized tests, evaluation scales, performance-based assessments, interviews, and observations. Factors influencing instrument selection include assessment goals, student characteristics, and available resources. The benefits of student characteristic evaluations include informing adaptive instruction, providing targeted support, and monitoring student progress. Effective evaluation of student characteristics is crucial for implementing the Merdeka Curriculum and supporting student-centered learning in Indonesia. The study emphasizes the need for a shift towards process-oriented assessment and highlights the importance of collaboration among educational stakeholders to create an inclusive learning environment.

This research aims to: (1) To find out how the use of a guided discovery model assisted by interactive e-modules can increase students' understanding of concepts. (2) To determine the increase in students' understanding of concepts after using the guided discovery model assisted by interactive e-modules. The subjects of this research were all 33 students in class VIII-3. The first procedure of this research is to give an initial test to students, in order to see students' ability to understand initial concepts, the second is to carry out learning using a guided discovery model assisted by interactive e-modules with rectangular material. The research consisted of 2 cycles with a teaching process of 4 meetings, where after 2 meetings in each cycle a concept understanding test was given to see students' concept understanding abilities. The form of questions for each test is a description. Before the test is tested, it is first validated by a validator. In the initial test, students' conceptual understanding abilities were in the very poor category with an average of 29, where no students experienced the level of learning completeness. After the implementation of cycle I, the level of students' ability to understand concepts was in the poor category with an average of 57.93 and 5 students (15.15%) reached the level of learning completeness. In the implementation of cycle II, the level of students' ability to understand concepts was in the very good category with an average of 87.31 and 30 students (90.90%) reaching the criteria for completion. The G value on the gain index is 0.70035 in the high category, as well as the overall indicator criteria for understanding concepts and observations are in the good category (61-80%). Based on the research analysis, it is clear that the use of a guided discovery model assisted by interactive e-modules can improve the ability to understand concepts in class VIII students.

The ability to think creatively mathematically, defined as the capacity to generate novel, diverse, and valuable mathematical ideas or solutions to problems with fluency, flexibility, originality, and elaboration, is a crucial skill in facing the challenges of the 21st century. However, a comprehensive understanding of the influencing factors is still limited. This systematic review aims to integrate and synthesize current research on factors influencing mathematical creative thinking abilities from a multidimensional perspective. A systematic search method was conducted on the Scopus database for studies published between 2019 and 2024. The results show the complexity of interactions between cognitive (thinking style, analogical reasoning, computational thinking), affective (self-efficacy, attitudes towards mathematics, self-regulated learning), and contextual (learning approaches, technology integration, background) factors from the 31 articles analyzed. cultural background) in influencing mathematical creativity. The analysis also revealed differences in influencing factors between levels of education from junior high school to college. These results stress how important it is to look at math creativity as a whole. They also have important implications for how math is taught and for future research, such as the need for longitudinal studies and the creation of integrative theoretical models

Pembelajaran matematika abad ke-21 menuntut pendekatan yang tidak hanya berfokus pada penguasaan prosedural, tetapi juga pada pemahaman konseptual yang mendalam, kemampuan berpikir kritis, dan transfer pengetahuan ke berbagai konteks kehidupan. Artikel ini membahas rancangan pembelajaran matematika berbasis pendekatan deep learning, bukan dalam konteks kecerdasan buatan, melainkan sebagai pendekatan pedagogis yang mengintegrasikan tiga prinsip utama: meaningful (bermakna), mindful (sadar-reflektif), dan joyful (menyenangkan). Pembelajaran bermakna dibangun melalui aktivitas kontekstual dan soal terbuka yang mengaitkan konsep matematika dengan situasi dunia nyata. Pembelajaran yang reflektif dan sadar proses difasilitasi melalui diskusi, refleksi metakognitif, dan evaluasi. Sementara itu, suasana belajar yang menyenangkan diciptakan melalui partisipasi aktif, eksplorasi bebas, dan pengakuan terhadap berbagai cara berpikir siswa. Kerangka teori mencakup konstruktivisme, teori transfer dan metakognisi, serta evaluasi berbasis proses. Implementasi pendekatan ini mengharuskan transformasi peran guru sebagai fasilitator, kurikulum yang fleksibel dan berorientasi pada eksplorasi makna, serta lingkungan belajar yang suportif dan kolaboratif. Disimpulkan bahwa pendekatan deep learning dengan prinsip meaningful, mindful, dan joyful dapat meningkatkan keterlibatan siswa, memperdalam pemahaman, serta membangun sikap positif terhadap matematika.
