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

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
