This study explores the mathematical literacy challenges faced by students at SMK Negeri 2 Bawang, Banjarnegara Regency, in learning exponential concepts, which are analyzed through the lens of the Independent Regular Learning (SRL) level. Using a descriptive qualitative approach, this study involved three student subjects representing high, medium, and low SRL categories. Data was collected through mathematical literacy tests, SRL questionnaires, and interviews. The research findings indicate that variations in SRL levels significantly influence the types of difficulties students experience. Students with low SRL face various challenges, including understanding the context of the problem, building mathematical models, and interpreting results. Students with moderate SRL demonstrate the ability to understand problems but have difficulty selecting appropriate problem-solving strategies and accurately representing contextual situations in mathematical form. Meanwhile, students with high SRL exhibit systematic and reflective thinking but encounter obstacles connecting mathematical outcomes to real-life contexts. These findings underscore the role of SRL in shaping students' mathematical literacy challenges. Further research is recommended to investigate additional internal factors that influence mathematical literacy in order to develop more adaptive and targeted teaching strategies

This study explores the challenges faced by vocational students in solving contextual problems in statistics using the TEFA (Teaching Factory) approach, aimed at enhancing their analytical and problem-solving skills—competencies that are highly valued in the industrial world. The purpose of this research is to analyze the difficulties students encounter when solving TEFA-based contextual problems in statistical topics. The subjects of this study were 38 tenth-grade students from class X TO 9 at SMK Kesatrian Purwokerto, selected based on their even semester daily test scores. The students were categorized into three groups: high (HC), medium (MC), and low (LC), based on the class average and standard deviation. This research employed a qualitative descriptive method. The findings revealed that students in the high category were generally able to understand statistical concepts and accurately calculate the mean, median, and mode. However, some students in this group did not sort the data from smallest to largest when calculating the median. Students in the medium category had difficulty recalling how to compute the mean, often resulting in incorrect answers; although the mode was correct, the median was not. Meanwhile, students in the low category acknowledged that they lacked understanding of how to calculate the mean, median, and mode.

Banyumas and Pekalongan batik are local cultural heritages of Central Java that contain philosophical values, regional identity, and geometric patterns. Although batik has been widely known as a uniform, its use as a medium for learning mathematics, especially transformation geometry, is still limited. This study aims to examine the relationship between Banyumas and Pekalongan batik motifs with the concept of transformation geometry and the cultural values contained. A qualitative approach with ethnographic methods was used through observation, documentation, in-depth interviews, and field notes. The subjects of the study included cultural figures, batik craftsmen, and tour guides at the Anto Jamil Batik Center (Banyumas) and the Pekalongan Batik Museum. The study focused on the Jahe Srimpang and Babon Angrem motifs (Banyumas), as well as Jlamprang Gunungan and Jlamprang Seamless (Pekalongan). The results showed that these motifs contain elements of geometric transformation such as translation, rotation, symmetry, reflection, and dilation. This study recommends the use of batik as a source of mathematics learning based on local wisdom.

The ability to solve mathematical problems is one of the main competencies that need to be mastered in mathematics learning. However, a number of studies reveal that students still experience obstacles in solving math problems, especially on the topic of circles. The purpose of this study is to explore the various causes of difficulties of grade VIII students in solving mathematical problems related to circle material and offer alternative solutions that can be used in the learning process. This research was conducted with a descriptive qualitative approach through a case study of several junior high school students in grade VIII. The findings of this study show that the main obstacles for students lie in the lack of understanding of the basic concept of circles, errors in the use of formulas, and limitations in designing problem-solving steps. Therefore, problem-based learning strategies and contextual learning approaches are recommended to be implemented to support improved student understanding.
