ANALISIS KONSEPTUAL POTENSI ZENO'S PARADOX SEBAGAI SARANA PENGUATAN INTUISI SISWA DALAM MEMAHAMI LIMIT DAN DERET TAK HINGGA

Fiqri Subhan — 2026-06-26

The concept of limits and infinity is a fundamental foundation in advanced mathematics; however, it often creates conceptual difficulties for students due to its abstract nature. One approach that can be used to strengthen students’ conceptual understanding is through the use of Zeno’s Paradox. This paradox describes the problem of motion through the division of distance that continues indefinitely, making it closely related to the concepts of limits and infinite series in calculus. This study aims to conceptually analyze the potential of the Zeno Paradox in strengthening students’ mathematical intuition regarding the concepts of limits and infinity in mathematics learning. The research employed a qualitative approach using a literature study (library research) method. Data were obtained from various scientific journal articles, conference proceedings, and books relevant to the concepts of limits, infinity, mathematical intuition, and Zeno’s paradox in mathematics education. Data analysis was conducted using content analysis techniques, including data reduction, categorization, conceptual analysis, and conclusion drawing. The results of the study indicate that Zeno’s Paradox has pedagogical potential as a means to generate cognitive conflict that can strengthen students’ mathematical intuition in understanding the concepts of limits and infinity. Through paradox illustrations, students can understand that processes that occur without bound do not always produce infinite values but can approach a particular value. Therefore, the Zeno Paradox can serve as an alternative approach in mathematics learning to strengthen students’ conceptual understanding of limit concepts.

SYSTEMATIC LITERATURE REVIEW: INTEGRASI PRINSIP DEEP LEARNING DALAM MODEL PEMBELAJARAN KOOPERATIF UNTUK MEREDUKSI KECEMASAN MATEMATIS SISWA SMP

Adelia Putri — 2026-06-26

Mathematical anxiety remains a major obstacle for junior high school students in learning mathematics. The present study applied a Systematic Literature Review (SLR) framework guided by the PRISMA approach to investigate the integration of cooperative learning and deep learning as a means of addressing mathematical anxiety. Searches were carried out across the Garuda and Google Scholar databases covering publications from 2020–2026, producing an initial pool of 129 articles, subsequently narrowed down to 6 studies that satisfied the inclusion criteria. The data were analyzed qualitatively using a narrative analysis technique by categorizing findings based on learning characteristics, the effects on mathematical anxiety, as well as the strengths and limitations of each approach. The results demonstrate that combining these two approaches fosters deeper learning by facilitating social interaction and consolidating conceptual understanding, which in turn contributes to alleviating students' mathematical anxiety. However, the practical implementation of this integration continues to encounter obstacles, most notably concerning instructional time allocation and the preparedness of both teachers and students. In light of these findings, the integration of cooperative learning and deep learning emerges as a viable and effective strategy for enhancing the quality of mathematics instruction while simultaneously mitigating students' mathematical anxiety.

This systematic literature review aims to identify and synthesize literature on the causes, impacts, and solutions to mathematics anxiety in mathematics education students or prospective mathematics teachers during teaching practice. The literature search was conducted using the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) protocol through the Google Scholar and Garuda databases with a publication year range of 2016 - 2026. A total of 85 articles were found in the identification stage. Through the PRISMA screening stages, 4 articles that met the inclusion criteria were obtained to be analyzed in-depth using qualitative narrative synthesis.. The findings indicate that the causes of anxiety are dominated by lack of material preparation, low self-confidence, and students' fear of being unable to answer questions or interact with students. The impact is reflected in the cognitive aspects (loss of focus or blank) and somatic aspects (heart palpitations), which lead to passive teaching styles, hesitation, and minimal interaction among students. The conclusion of this study emphasizes the urgency of evaluating the learning program for prospective teacher students so that it not only emphasizes mastery of material and pedagogy, but also includes psychological development, emotional regulation, and the creation of a constructive learning environment to build self-confidence as prospective educators.

Wa Ode Dahiana — 2026-06-26

This study aims to uncover the multidimensional error patterns of students in solving algebra problems from the perspective of semiotic representation at various ability levels. This study used a qualitative approach involving 30 seventh-grade junior high school students. The research subjects were selected by purposive sampling, then six students were determined representing the high, medium, and low ability categories. Data were obtained through written tests and interviews, then analyzed based on Nolting's error classification, which includes misread direction error, careless error, concept error, application error, test procedure error, and transformation error. The results showed that students at all ability levels experienced difficulties in converting between representations (transformation error), especially from verbal to symbolic (algebraic expression) and symbolic to geometric expression. High-ability students were able to reason symbolically but failed to connect it to the visual context (graphical expression), while medium-ability students tended to use trial and error strategies that resulted in application errors. Students in the low-ability group showed concept errors and fundamental representation errors (transformation errors). In general, transformation errors were the most dominant type of error, followed by concept errors and application errors. These findings indicate that algebra learning needs to be designed by integrating various semiotic representations so that students' conceptual understanding can develop more deeply.

EVALUASI KETERKAITAN KURIKULUM SEKOLAH MENENGAH KEJURUAN DENGAN KEBUTUHAN DUNIA KERJA DI SEKTOR INDUSTRI

Firman Firman — 2026-06-26

Vocational High Schools (SMK) serve as a vital foundation in generating a prepared workforce equipped with specialized skills that align with industry requirements. SMKs should produce graduates who can utilize their skills in professional environments; thus, it is crucial to align the SMK curriculum with industry requirements to establish a connection between the education sector and the labor market. Nonetheless, in reality, the correspondence between the SMK curriculum and the actual demands of the industrial sector continues to be a complicated matter. A key reason for this gap is the insufficient participation of the industry in creating and designing the curriculum. An inflexible and top-down curriculum frequently fails to adapt to the fast-changing dynamics and shifting demands of industry, especially during the Fourth Industrial Revolution. The SMK curriculum needs to equip graduates to meet the demands of the job market, especially in the industrial field. Nonetheless, numerous graduates are considered unready for employment because of a disconnect between the curriculum material and the requirements of the industry. The objective of this research is to assess how well the vocational school curriculum corresponds with labour market demands and to determine the factors leading to this discrepancy. The approach employed involved a review of literature from different sources and policy reports. The method used for analysis was content analysis, with the data examined through multiple stages: (1) gathering literature, (2) selecting sources based on relevance and reliability, (3) data condensing, (4) categorising themes, and (5) forming conclusions. The study's findings reveal that industry participation in curriculum development is limited, the curriculum inadequately adapts to technological advancements, and the incorporation of soft skills is lacking. Enhanced cooperation between vocational institutions and the industrial sector is necessary to guarantee graduates are better equipped and more applicable.

ANALISIS HUBUNGAN SELF-REGULATED LEARNING TERHADAP KEMAMPUAN BERPIKIR REFLEKTIF MATEMATIS SISWA SMP: SYSTEMATIC LITERATURE REVIEW

Anisa Anisa — 2026-06-26

Mathematical reflective thinking ability is a higher-order skill vital in mathematics education. Yet, research on its link with self-regulated learning (SRL) among junior high school students is limited and unsystematically reviewed. This study examines the relationship between SRL and mathematical reflective thinking ability through a 10-year (2016–2026) systematic literature review, identifying patterns and implications for mathematics education at the junior high school level. Using Systematic Literature Review (SLR) per PRISMA guidelines, searches on Google Scholar, ERIC, and accredited national journals employed keywords: "self-regulated learning," "mathematical reflective thinking ability," and "junior high school students." Of 30 articles identified, 15 met the inclusion criteria and were analyzed using descriptive qualitative methods. Findings show a consistent positive correlation between SRL and mathematical reflective thinking ability. High-SRL students more comprehensively fulfill reflective thinking indicators (reacting, elaborating, contemplating) compared to medium/low-SRL peers. This relationship is mediated by the structural alignment between SRL phases (forethought, performance control, self-reflection) and the cognitive processes underlying reflective thinking. Problem-Based Learning (PBL) consistently optimizes the role of SRL in developing mathematical reflective thinking ability. The study strengthens the empirical basis for fostering SRL in junior high school mathematics learning and urges the integration of metacognitive strategies into the curriculum

PERSEPSI SISWA TERHADAP PENERAPAN PROBLEM BASED LEARNING BERBASIS ETNOMATEMATIKA PADA MATERI SPLDV

Dwi Susanti — 2026-06-26

Problem Based Learning is a learning model that focuses on contextual problem solving to help students understand concepts in a more meaningful way. In its implementation, PBL can be combined with ethnomathematics by linking learning materials to cultural contexts, so that the problems presented become closer to students’ experiences. This study aims to examine students’ perceptions and identify the factors that influence them in the SPLDV material. This study uses a qualitative approach with 30 eighth-grade students of SMP Negeri 22 Sarolangun as the subjects. Data were collected through questionnaires, interviews, and observations. The results of the study show that students’ perceptions of learning are in the high, medium, and low categories based on the questionnaire results. This shows that students’ perceptions vary among individuals. Learning that is linked to cultural contexts can help students’ understanding and increase their interest and engagement, but it has not been felt evenly by all students. These perceptions are influenced by internal factors, such as attention, motivation, experience and prior knowledge, attitudes, and self-confidence, as well as external factors which include the characteristics of learning and the social, cultural, and physical environment. Thus, students’ perceptions are formed through the interaction of various factors in learning experiences

Laurin Wijayanti Khoiriyah — 2026-06-26

Mathematics learning is expected to develop students' geometric thinking skills and cognitive strategies, but in fact, these skills are still relatively low, especially in the material of functions. This study aims to analyze students' cognitive strategies in solving inverse function problems in terms of the Van Hiele geometric thinking level. This study uses a qualitative approach with a descriptive research type. The subjects of the study consisted of eleventh grade students selected based on Van Hiele's thinking levels from level 0 to level 3. Data were collected through tests, interviews, and documentation, then analyzed through data reduction, data presentation, and drawing conclusions. The results of the study show that students' cognitive strategies differ at each Van Hiele thinking level. Students at the low level tend to use simple procedures and are not yet able to explain concepts in depth, while students at the high level are able to use systematic strategies, analyze conceptual relationships, and provide logical reasons for solving inverse function problems. Differences in geometric thinking abilities also affect students' cognitive strategies in solving problems. Therefore, learning is needed that can train students to think gradually so that geometric thinking abilities develop more optimally

HUBUNGAN MATH ANXIETY DAN COMPUTATIONAL THINKING TINJAUAN SISTEMATIS DALAM PERSPEKTIF HIGHER ORDER THINKING SKILLS

Nia Dahlia — 2026-06-26

This study is motivated by the importance of higher order thinking skills (HOTS) and computational thinking (CT) in 21st-century mathematics education, as well as the affective factor of mathematics anxiety that may influence these abilities. The purpose of this study is to examine the relationship between mathematics anxiety and computational thinking skills, and to analyze the role of HOTS within this relationship through a systematic literature review (SLR) approach. The method follows the PRISMA model, including identification, screening, eligibility assessment, and data synthesis stages, involving 15 articles indexed in Scopus and Sinta, retrieved from Google Scholar (6 Scopus-indexed and 9 Sinta 1-4 indexed articles) published between 2021 and 2026. The findings indicate that most studies show a negative relationship between mathematics anxiety and CT, where increased anxiety is associated with lower computational thinking ability. However, this relationship is contextual and influenced by technology-based and innovative learning interventions. Furthermore, CT acts as a mediating variable that can reduce the negative impact of anxiety on learning outcomes, while HOTS functions as a cognitive framework linking affective and cognitive aspects. These findings highlight the importance of integrating CT and HOTS in mathematics learning to enhance students’ thinking quality while minimizing mathematics anxiety.

Muhammad Ilham Wahyudi — 2026-06-26

Numeracy competence is a fundamental skill that determines students' readiness to meet twenty-first century demands. Persistent cross-national gaps in achievement, most recently documented in PISA 2022, suggest that differences in curriculum design play a substantial role in shaping those disparities. This study examined the relationship between mathematics curriculum structure and the development of numeracy competence through a comparative analysis of Indonesia and Finland. A Systematic Literature Review (SLR) guided by the PRISMA 2020 framework was conducted across Google Scholar, Scopus, and SINTA databases using Publish or Perish, producing 15 articles from an initial pool of 130 based on predetermined inclusion criteria and quality appraisal using an instrument adapted from the Critical Appraisal Skills Programme (CASP). Thematic analysis suggests that Finland's coherent, conceptually oriented curriculum appears to be associated with the development of students' reasoning and problem-solving abilities, whereas Indonesia's curriculum, which remains comparatively fragmented and procedurally focused, appears to constrain the development of contextual numeracy. The results indicate that curriculum effectiveness in supporting numeracy is determined not merely by written content, but by the extent to which curriculum structure shapes students' overall learning experiences. The implications of this study are relevant to curriculum policy and mathematics curriculum design in Indonesia.

EFEKTIVITAS MODEL CUPS BERBANTUAN E-LKPD DALAM MENINGKATKAN PENALARAN DAN KOMUNIKASI MATEMATIS SISWA

Noviana Dwi Rahmadani — 2026-06-26

Mathematical reasoning and communication skills are essential for building conceptual understanding, yet conventional learning practices often fail to optimize them. This study aims to examine the effectiveness of the Conceptual Understanding Procedures (CUPs) model assisted by E-LKPD (Electronic Student Worksheet) in enhancing both abilities. Using a quantitative approach with a quasi-experimental design, the study was conducted on three eighth-grade classes at SMPN 21 Bandar Lampung selected through cluster random sampling: experimental class 1 (CUPs assisted by E-LKPD), experimental class 2 (CUPs without E-LKPD), and control class (discovery learning). Data were collected through tests of mathematical reasoning and communication, then analyzed using MANOVA at a significance level of 5%. The results showed that the CUPs model assisted by E-LKPD provided the most significant improvement compared to the other two classes. Based on MANOVA, there was a significant simultaneous effect on mathematical reasoning and communication abilities, with Wilks' Lambda = 0.014, F = 2737.056b, p = 0.000 (p < 0.05), and partial eta squared (η²) = 0.986, indicating a large effect. This success is supported by the ease with which the E-LKPD presents interactive questions that structure conceptual understanding procedures, although technical constraints such as network instability and some students' relaxed attitudes were observed. These findings confirm the effectiveness of the CUPs model assisted by E-LKPD as an innovative learning alternative that addresses the challenge of developing higher-order thinking skills in the digital era

This study aimed to determine the effect of the Student-Centered Approach (SCA) assisted by YouTube media on the mathematical literacy and mathematical reasoning abilities of tenth-grade students at MAN 1 Bandar Lampung. The study employed a quantitative approach using a quasi-experimental method with a post-test-only control group design. The research sample consisted of two experimental classes that received instruction through the Student-Centered Approach (SCA) assisted by YouTube media and one control class that was taught using the Discovery Learning model. Data were collected through tests measuring students' mathematical literacy and mathematical reasoning abilities and were analyzed using Multivariate Analysis of Variance (MANOVA). The results revealed that the average scores of mathematical literacy and mathematical reasoning in the experimental classes were higher than those in the control class. Hypothesis testing indicated that the Student-Centered Approach (SCA) assisted by YouTube media did not have a significant effect on students' mathematical literacy ability (sig. = 0.056 > 0.05). However, it had a significant effect on students' mathematical reasoning ability (sig. = 0.020 < 0.05). Furthermore, the MANOVA results showed that the Student-Centered Approach (SCA) assisted by YouTube media had a simultaneous effect on both mathematical literacy and mathematical reasoning abilities (sig. = 0.035 < 0.05). Based on these findings, it can be concluded that the Student-Centered Approach (SCA) assisted by YouTube media is effective in improving students' mathematical reasoning ability and has a simultaneous influence on both mathematical literacy and mathematical reasoning abilities.
