The purpose of learning mathematics is to change the performance of each student in the cognitive, affective and psychomotor domains. One part of the cognitive domain that is needed when studying mathematics is understanding concepts. Hadi and Kasum (2015) reiterated the notion that conceptual understanding is very important in solving mathematical and contextual problems. Based on the results of a preliminary study conducted by researchers at SMPN 1 Krian, information was obtained that students' conceptual understanding was still low, judging from the average daily test results for number pattern material below the KKM. The type of research used in this research is qualitative research. This research was conducted at SMPN 1 Krian. The subjects in this study were two class VIII students of SMPN 1 Krian who had the highest and lowest test results. The data analysis method used in this study consisted of data reduction, data reclassification, and drawing conclusions. The result of this research is that the high subject fulfills the four indicators of understanding the concept which consists of restating a concept, classifying the types of number patterns, applying the concept into a mathematical representation, and selecting certain procedures from a concept. Meanwhile, the low subject did not meet two indicators, namely restating a concept, three indicators fulfilled but not perfect which consisted of classifying the types of number patterns, applying concepts into mathematical representations, and selecting certain procedures from a concept.

Proper vertex coloring c of a graph G is a graceful coloring if c is a graceful k-coloring for k∈{1,2,3,…}. Definition graceful k-coloring of a graph G=(V,E) is a proper vertex coloring c:V(G)→{1,2,…,k);k≥2, which induces a proper edge coloring c':E(G)→{1,2,…,k-1} defined c'(uv)=|c(u)-c(v)|. The minimum vertex coloring from graph G can be colored with graceful coloring called a graceful chromatic number with notation χg (G). In this paper, we will investigate the graceful chromatic number of vertex amalgamation of tree graph family with some graph is path graph, centipede graph, broom and E graph.

Writing scientific papers that include complex mathematical notation requires specialized text editors. This study provides a comprehensive review of various text editors, evaluating their effectiveness for tasks involving mathematical notation. The comparison includes freeware and paid software such as OpenOffice, LibreOffice, Microsoft Word, TeXmacs, and Overleaf, examining aspects like file formats, file size, installation process, learning curve, collaboration ease, and output formats. Through a detailed analysis of existing literature, the study highlights the strengths and weaknesses of each editor, with a particular focus on LaTeX's precision and versatility. The findings suggest that LaTeX is the preferred choice for its high-quality output, while Overleaf offers significant advantages for collaborative projects. Freeware options like GNU TeXmacs and LibreOffice are also viable alternatives, each with unique benefits. The study concludes with recommendations on choosing the appropriate text editor based on specific project requirements and user preferences.

Pendidikan matematika mengalami perubahan signifikan di era digital, dengan hadirnya berbagai model pembelajaran inovatif yang dirancang untuk meningkatkan keterlibatan dan pemahaman siswa. Salah satu model yang populer adalah kelas terbalik (flipped classroom), di mana siswa mempelajari materi secara mandiri melalui media digital sebelum datang ke kelas untuk berdiskusi dan mendalami konsep dengan bantuan guru. Artikel ini mengeksplorasi efektivitas model kelas terbalik dalam konteks pendidikan matematika melalui pendekatan kualitatif berbasis studi literatur atau library research. Berbagai sumber literatur yang relevan dianalisis untuk memahami bagaimana kelas terbalik memengaruhi keterlibatan, motivasi, dan pemahaman siswa terhadap materi matematika. Hasil penelitian menunjukkan bahwa model kelas terbalik dapat meningkatkan partisipasi aktif siswa dalam proses pembelajaran matematika, serta membantu siswa dalam mengembangkan pemahaman yang lebih mendalam terhadap konsep-konsep yang kompleks. Dengan memanfaatkan teknologi digital, siswa memiliki fleksibilitas dalam mengakses materi kapan saja dan di mana saja, sehingga dapat belajar sesuai kecepatan mereka masing-masing. Namun, implementasi model ini juga menuntut kesiapan guru dalam merancang materi pembelajaran yang menarik dan interaktif, serta akses yang memadai terhadap perangkat digital bagi siswa. Artikel ini berkontribusi pada diskusi mengenai transformasi pendidikan matematika di era digital dan memberikan wawasan tentang potensi dan tantangan dalam menerapkan model kelas terbalik secara efektif.

College is an educational institution that has an important role in providing contributive discourse in social life. How the tradition of critical thinking, respecting pluralistic thinking, and trying to strengthen a multicultural society becomes an academic culture in the intellectual arena. In developing an academic culture, the academic community, in this case becomes an agent, with the appropriate capital and habitus, can change or achieve certain goals. So, to make this happen, analysis and practice are needed that support the development of academic culture. One of the roles of this research is to explain Pierre Bourdieu's thinking and its relevance to the development of academic culture in higher education. Of course, the academic culture in question is in accordance with the goals of each educational institution. Apart from providing Bourideu's perspective, this research also aims to explain the steps that must be taken by agents in an intellectual arena. This research uses a literature or library research method to understand Bourdieu's basic thought concepts related to academic culture. Finally, Bourdieu's concept of thought provides analysis and practices that must be carried out in developing an academic culture in higher education. And how to overcome the problems that occur in it.

This study aims to develop an interactive e-worksheet (E-LKPD) based on Liveworksheets for differentiated learning on the topic of pyramids (limas) in Phase D that is valid, practical, and effective in improving student learning outcomes. The research employed a development method using the ADDIE model, involving eighth-grade students as subjects. Instruments used include validity, practicality, and effectiveness instruments, with data collected through questionnaires and learning outcome tests. The developed product consists of three E-LKPDs tailored to students’ readiness levels: developing, proficient, and highly proficient. Validation results show an average score of 3.81 out of 4, categorized as very valid. Practicality was measured through teacher and student responses, yielding an average of 76.26%, which falls into the practical category. Effectiveness was assessed based on the learning test results, showing a mastery level of 89%, indicating that the E-LKPD is effective for classroom use. This study is essential due to the growing need for interactive learning materials that accommodate differences in student learning abilities, particularly within the current differentiated learning framework. Moreover, the use of digital tools like Liveworksheets remains underutilized, especially in mathematics topics such as pyramids. This E-LKPD is expected to make learning more engaging and tailored to individual needs, and serve as a foundation for future development of more innovative digital learning materials.
