Abstract

Derivative material is essential in developing students’ critical thinking skills and its application in various scientific fields, specifically in mathematics. However, numerous studies revealed that many students still considered this material difficult, which often causes students to make mistakes in solving derivative problems. This study aims to analyze students' errors in solving derivative problems. This research method used systematic literature review with data synthesis process, qualitative data analysis through thematic analysis, and PRISMA method for data selection which obtained 10 articles from 232 articles on the Google Scholar, Semantic Scholar, and Scopus pages. The analysis results showed uneven fluctuations in the number of studies, peaking in 2022. The distribution of research covers nine provinces in Indonesia, with a dominance in the NTB province, although the distribution is still uneven. Newman’s theory became the primary approach to analyzing student errors. Most of the research was published in SINTA 4 and SINTA 5 journals, while contributions in highly reputable journals are still minimal. The most dominant student error occurred at the encoding/looking back stage, which was caused by a lack of understanding of the derivative concept, inaccuracy, rushing, and lack of habit to re-examine the work. Other errors include conceptual, procedural, and technical errors related to derivative facts, concepts, operations, and principles. As a solution, interactive teaching materials based on the Newman procedure was recommended to improve students’ understanding of derivative concepts.         Keywords: derivative, mathematics, student errors, systematic literature review. DOI: http://dx.doi.org/10.23960/jpmipa/v25i4.pp1693-1704

Abstract

Mathematics education in the digital era needs to develop computational thinking as a problem-solving skill relevant to the challenges of the 21st century. This skill is closely related to logic and problem solving, which are the core of mathematics learning, such as in geometry. However, how computational thinking is implemented by students when they face geometry problems still needs to be explored further. This study aims to analyze and describe the computational thinking (CT) of junior high school students in Indonesia in solving geometry problems. The Participants were 25 students in grade VIII of an Indonesian junior high school. This study used a qualitative research design. Data collection techniques were carried out through tests and interviews. Data analysis techniques consisted of data reduction, data presentation, and conclusion. The results showed that 60% of students could use CT to solve geometry problems (achieving KKM), while 40% were still below KKM. CT components that students with scores above KKM can achieve include abstraction, decomposition, and algorithms. Meanwhile, students with low scores were identified as having not achieved any of the specified CT components. The computational thinking of junior high school students in geometry has developed quite well. Integrating CT into geometry learning can be a powerful tool for students to solve complex geometry problems.         Keywords: computational thinking, problem solving, geometry.DOI: http://dx.doi.org/10.23960/jpmipa/v25i1.pp300-312

Abstract

One of the competencies or learning goals in the 2013 curriculum is to promote curiosity, creativity, and the ability to arranging problem to build critical thinking which are necessary for intelligent life. However, in reality, students's critical thinking skills in mathematics are still not satisfactory. Mathematic’ material and critical thinking skills are two things that cannot be separated because mathematics material can be understood through critical thinking which is trained through learning mathematics. Learning number patterns aims to equip students to think critically, analyze, creatively, logically, and systematically. Students' critical thinking skills have related to the existence of cognitive aspects like how to complete a task, make procedures design, and be able to give the right solution in solving problems. This study aims to understand how students of junior high school solve math problems with number pattern material reviewed from students's critical thinking with Field-Dependent (FD) and Field-Independent (FI) cognitive style. The method used in this research is qualitative descriptive method with case study design. From the results of study conducted on 14 students, there were 64% students in the Independent field category and 36% students in the Dependent field category. Of the 2 students, among them taken in the Independent field category, they have high-level critical thinking skills and medium-level critical thinking skills. There are 2 students among those taken in the Dependent field category have critical thinking skills on medium level and low level.

Abstract

Penelitian ini bertujuan mendeskripsikan aspek literasi matematis yang terkandung dalam praktik menenun kain futus oleh masyarakat Amanuban melalui pendekatan etnomatematika. Studi ini menggunakan metode kualitatif dengan desain etnografi, di mana data dikumpulkan melalui observasi partisipatif, wawancara mendalam, dan dokumentasi visual terhadap proses menenun. Hasil penelitian menunjukkan bahwa praktik menenun futus merepresentasikan literasi matematis dalam tiga dimensi utama yaitu konten, proses, dan konteks. Pada dimensi konten, aktivitas ini mencakup konsep-konsep matematika seperti sistem bilangan, transformasi geometri, serta proporsi dan perbandingan. Pada dimensi proses, penenun secara intuitif melakukan operasi matematis seperti menghitung jumlah benang, melipat untuk membentuk pola simetris, dan mengatur waktu dalam proses pencelupan. Sementara itu, pada dimensi konteks, kemampuan matematis tercermin dalam pengorganisasian ruang dan bentuk, serta pengambilan keputusan terkait komposisi warna dan motif. Temuan ini memperkuat relevansi pendekatan etnomatematika dalam pembelajaran matematika yang kontekstual, sekaligus memberikan kontribusi terhadap pengembangan kurikulum berbasis budaya lokal dan penguatan identitas budaya masyarakat Amanuban.

Abstract

AbstractThe teke (gecko) and biklusu (lizard) motifs in lotis woven fabrics represent symbolic and spiritual values in Amanuban culture while also containing mathematical structures. However, these mathematical aspects are rarely explored, and local weaving traditions are seldom integrated into formal mathematics learning. This gap has led to limited use of cultural resources in supporting students’ understanding of geometry. Therefore, this study identifies the types of frieze patterns in three variants of these motifs and explores their potential for integration into mathematics education. A descriptive qualitative approach was employed, utilizing direct observation, documentation, and interviews with weavers and cultural elders. The primary data consisted of visual representations of the three motifs, which were analyzed through isometric transformations including translation, vertical and horizontal reflection, 180° rotation, and glide reflection. The classification was based on the seven types of frieze patterns as defined by the one-dimensional isometry group theory. The findings reveal that two motifs correspond to the F6 frieze pattern type, while one aligns with the F7 type, demonstrating varying degrees of geometric symmetry complexity. The teke and biklusu motifs can serve as effective contextual tools for mathematics instruction across educational levels, from pattern recognition in primary school to advanced discussions of isometry group theory in higher education. This approach aligns with the goals of the Merdeka Curriculum by linking mathematics learning to meaningful local contexts.

Abstract

The struggle of junior high school students to grasp One-Variable Linear Inequalities often stems from a lack of internal motivation and self-determination. Addressing this challenge, the present study explores the potential of a Local Instruction Theory (LIT) based learning design to foster students’ self-driven engagement in mathematics. Conducted in two instructional cycles with students in Lhokseumawe, Indonesia, the study employed a qualitative approach using a 24-item Likert-scale questionnaire measuring autonomy, competence, relatedness, and active willingness to learn. The results of the self-determination questionnaire analysis showed clear positive changes. The total subjects in this study was 57 students, of whom 31 participated in the first experimental phase (TE-1). Only 16% of students showed high self-determination. In contrast, in the second phase (TE-2) with 26 students as subjects in the first experimental phase (TE-1), only 16% of students demonstrated high self-determination. In contrast, in the second phase (TE-2), In the second phase (TE-2), the proportion of students with high self-determination increased from 16% to 35%, while the medium category decreased from 77% to 62% and the low category declined from 6% to 4%. These results highlight the promise of contextual, structured instruction supported by well-designed learning materials in cultivating students’ intrinsic motivation. More broadly, this study offers a compelling direction for designing affective-centered math instruction. Future research is encouraged to integrate multiple data sources and expand LIT implementation across diverse mathematical domains

Abstract

Penulisan artikel bertujuan untuk mendeskripsikan hakikat manusia sebagai animal educandum ditinjau dari perspektif pedagogik pada fase perkembangan anak usia pendidikan dasar dan implikaisnya. Metode penulisan artikel ini dengan pendekatan deskriptif kualitatif melalui kajian pustaka, telaah dokumentasi terkait, dan diskusi keilmuan pedagogik dengan mahasiswa S2 Prodi Administrasi Pendidikan Pascasarjana Unigal. Temuan dari kajian ini, secara fisik dan struktur tubuh, manusia memiliki beberapa persamaan dengan hewan lainnya terutama yang tergolong dalam kelas mamalia atau primata . Perbedaan mencolok antara manusia dengan hewan adalah pada otak.  Dengan struktur, bagian, dan fungsi otak yang dikembangkan dengan sempurna, maka potensi manusia akan maksimal untuk mencapai posisi tertinggi sesuai dengan fitrahnya. Berdasarkan teori multiple intelegences, manusia memiliki delapan kecerdasan yang dapat dikembangkan. Kedelapan jenis kecerdasan tersebut adalah kecerdasan: linguistic-verbal, matematis-logis, visual-spasial, musical, intrapersonal. interpersonal, kinestetis, dan naturalis. Untuk dapat mencapai potensi terbaiknya, maka manusia harus dididik dengan berbagai cabang keilmuan dan keterampilan menggunakan alat.  Berangkat dari potensi dan kebutuhan belajar manusia, maka lahirlah aliran-aliran  pendidikan seperti nativisme, empirisme dan konvergensi. Manusia sebagai 'animal educandum' yang mengandung makna bahwa manusia merupakan mahkluk yang perlu atau harus dididik, karena saat dilahirkan kondisinya sangat tidak berdaya sama sekali, padahal memilki berbagai potensi yang apabila dibantu dengan pendidikan akan menjadi manusia yang paripurna yang akan sangat berbeda dengan hewan Bertolak dari pandangan tersebut, secara implisit terlihat pula bahwa tidak mungkin manusia dipandang sebagai mahkluk yang harus di didik, apabila manusia bukan mahkluk yang dapat di didik.

Abstract

This study is a conceptual review that aims to explain how self-efficacy is integrated into mathematics learning based on Team-Based Learning (TBL). In the initial stage, researchers found 120 articles. After screening, 15 articles were selected that were relevant and in line with the research focus. The synthesis results showed that the integration of self-efficacy and TBL created a mutually reinforcing cycle. The TBL structure was proven to provide space for the formation of four main sources of self-efficacy (Bandura, 1997), namely mastery experience, vicarious experience, verbal persuasion, and affective states. The integration of the two creates a reciprocal relationship: high self-efficacy makes students more confident and persistent in facing challenges, while the collaborative and supportive TBL environment strengthens students' self-efficacy. TBL is not just a learning strategy, but also a space for students to develop confidence in learning mathematics.   Keywords: Self-efficacy, Team-Based Learning, Mathematics Learning, Collaborative Learning, Higher-Order Thinking Skills
