<![CDATA[This research was conducted based on the low ability of students' mathematical representation in class VIII SMP N 9 Purwokerto. One of the contributing factors is that the use of the learning approach used has not facilitated students in developing mathematical representation abilities. The solution that is considered capable of increasing the ability of mathematical representation is to apply learning with a realistic mathematical approach. The realistic mathematics approach provides opportunities for students to do modeling, depicting and symbolizing related to concrete problems. This research is a quantitative research with a quasi-experimental type with Nonequivalent Control Group Design. The population in this study were all students of class VIII SMP N 9 Purwokerto. The sample in this study was class VIII A with a total of 36 students and VIII B with a total of 36 students. The data analysis used is the z-test and the N-Gain test. The results of this study indicate that the realistic mathematical approach is effective in increasing students' mathematical representation abilities. From the results of the z-test showed a significant effect, the mathematical representation abilities of the experimental class students were higher. Then the results of the N-Gain test showed that the experimental class was in the medium category and the control class was in the low category. Thus the representation ability of the experimental class students is higher than that of the control class.]]>

<![CDATA[This study examines the relationship between self-efficacy in geometry and Pedagogical Content Knowledge (PCK) among Madrasah Ibtidaiyah teachers in Banyumas Regency. Self-efficacy was assessed in 79 sampled teachers using a multidimensional teaching self-efficacy scale focused on effectiveness and classroom management, while PCK was evaluated through tasks involving the perimeter and area of two-dimensional shapes. The findings reveal a weak correlation between self-efficacy and PCK, indicating limited interdependence. This highlights the need to address gaps in both areas. Within an Islamic context, the study emphasizes the relevance of tazkiyah (self-purification) and ilm (knowledge acquisition) as principles of teacher development. It recommends targeted training aligned with Islamic values to simultaneously enhance self-efficacy and PCK. Such an integrated approach aims to improve teaching skills, foster holistic growth, and create a nurturing learning environment that benefits both teachers and students.]]>

<![CDATA[This study aimed to develop a specific Mathematical Content Knowledge (MCK) test focused on multiplication for pre-service mathematics teachers in Indonesia and Türkiye. No assessment tool exists to measure MCK related to multiplication among pre-service mathematics teachers. We used convenience sampling to obtain data from third- and fourth-year pre-service teachers in Indonesian and Turkish mathematics teacher education programs. The test items were administered to 423 Indonesian pre-service mathematics teachers and 413 Turkish pre-service mathematics teachers, and their responses were analyzed using factor analysis. The MCK test was found to be reliable, with 18 items that were grouped into four components: procedural knowledge of multiplication (C1), understanding of multiple representations (C2), conceptual knowledge of multiplication (C3), and anticipating students' thinking (C4). The study results suggest that a valid MCK test helps evaluate multiplication in these four components. Additionally, the study findings indicate that Indonesian pre-service teachers score higher in the C1 and C4 categories, while Turkish pre-service teachers score higher in the C2 and C3 categories.]]>

<![CDATA[Mathematics teachers’ beliefs play an important role in the mathematics teaching practices. However, the instruments used to measure the mathematics on certain contents are still limited. Thus, this study was conducted to develop a Multiplication Beliefs Questionnaire (MBQ) to identify and examine the profile of Turkish pre-service mathematics teachers’ beliefs. The samples of this study consisted of 414 four-year pre-service primary mathematics teachers from 18 different universities in Turkey collected using a convenience sampling technique. The validity of the questionnaire was analyzed using an exploratory factor analysis (EFA). We obtained four components of beliefs in multiplication covering, remote belief in multiplication (C1), multiplication operation belief in mathematics textbooks (C2), dynamic belief in multiplication learning (C3), and self-efficacy belief in multiplication problems (C4). The results showed that the pre-service mathematics teachers’ beliefs in components C1, C3, and C4 were positive, while component C2 was neutral. This study had an essential contribution to the mathematics literature since developing a questionnaire on multiplication distributed to the pre-service teachers. The previous studies showed that belief was subjective yet objectively influenced knowledge. Thus, identifying the pre-service teachers’ beliefs in teacher education may provide various benefits in reforming mathematics teaching.]]>

<![CDATA[This study aimed to test the effectiveness of Bruner’s theory-guided discovery learning in enhancing the mathematical reasoning ability of elementary school students. The study was done with a quasi-experimental design and an experimental group instructed with discovery learning based on Bruner’s theory was compared with a control group instructed expositively. he population of this study consisted of elementary schools (SD/MI) in Banyumas Regency with accreditation levels A and B, totaling 38 schools. Using a stratified random sampling technique, four schools were selected—each representing schools with accreditation A and B—and were assigned as the experimental and control groups. The findings indicate that the experimental group significantly enhanced the ability to identify patterns, generalize, and construct and test mathematical arguments compared to the control group. However, the post-test scores suggest that students’ reasoning abilities in the experimental group have not reached a maximum point, possibly because they had not been exposed to enough experience in exploratory learning. The ANOVA test also failed to reveal any significant interaction between school accreditation category and instruction type on the student’s mathematical reasoning ability. With well-planned deployment and even more tailored to students’ characteristics, Bruner’s theory-guided discovery learning has immense potential to improve the quality of mathematics education at the elementary school level.]]>

<![CDATA[Learning material is an important part of the implementation of learning, so teachers should be able to design, arrange, and develop their learning material. There are a lot of mathematics learning materials on the market but they are still rarely integrated with Islamic studies. Therefore, the purpose of this study is to develop Islamic context-based learning material to increase students' mathematical understanding. This study is research and development using the PPE model which consists of three stages, namely planning, production, and evaluation. The data collecting techniques used are tested to find out the students' mathematical understanding and questionnaire to find out expert's assessment. The data is analyzed quantitatively using descriptive data analysis techniques. The data obtained from the questionnaire is quantified to get results in the form of percentages to find out the results of the questionnaire from the validation of the learning material experts. The results showed that Islamic context-based learning material has fulfilled the requirements to be considered feasible to be used in the learning process and is feasible to be used as learning support to increase students' mathematical understanding. ]]>

<![CDATA[Banyumasan batik is one of Indonesia's cultural heritages from Banyumas Regency, which has unique and interesting patterns and motifs. This research paper describes the mathematical modelling of geometric transformations in Banyumasan batik. Geometric transformation is a mathematical technique for changing the shape or position of an object on a plane. This is qualitative research with an ethnographic approach. Data is collected through observation, interviews, and documentations. The data obtained were analysed using content analysis to identify various Banyumasan batik motifs that can be transformed into geometric forms. This study describes the basic geometric transformations, namely translations in Sekar Tirta batik motif, reflections in Bawor Kembar batik motif, dilations in Kawung Jenggot batik motif, and rotations in Manggar Bawor batik motif which applied to Banyumasan batik motifs. The results of this study include geometric transformations of Banyumasan batik motifs which are expected to positively contribute to the development of Indonesian art and culture, especially in the field of batik, enrich insight and knowledge about the application of mathematics in everyday life, and can be used for mathematical modelling and mathematics education based on local culture.]]>

<![CDATA[Background: The leadership of school principals plays a crucial role in shaping students' character in multicultural environments such as SMK Negeri 1 Purwokerto. However, there has been no specific study that examines the influence of leadership strategies on the development of students’ Islamic character within the context of cultural and religious diversity. This study addresses that academic gap by integrating three aspects: leadership strategies, Islamic character, and the multicultural context. Methods: This is an associative quantitative study employing a field research approach. A sample of 80 students was selected from a population of 403 students in grades X and XI using simple random sampling. Data were collected through interviews, observations, and Likert scale-based questionnaires, and were then analyzed using validity, reliability, normality, linearity, and simple linear regression tests. Findings: The findings indicate that the instrument was valid (r-count > 0.2199) and reliable (Cronbach’s Alpha: X = 0.742; Y = 0.729). The data were normally distributed (sig. = 0.168) and exhibited a significant linear relationship (sig. = 0.001). Simple linear regression analysis revealed that leadership strategies had a substantial influence on Islamic character (sig. = 0.003), but the effect was negative (regression coefficient b = -0.244) with a low contribution (R² = 0.105). This suggests that an increase in leadership strategies may potentially decrease Islamic character, possibly due to a lack of collaborative approaches or the dominance of external factors (89.5%). Conclusion: The conclusion highlights the significance of transformative-relational leadership, which entails embodying Islamic values and conducting contextual evaluations in multicultural settings. Novelty/Originality of this article: The novelty of this study lies in the integration of the three aspects and the revelation of a paradoxical negative relationship that has not been explored in previous research.]]>

<![CDATA[Background: Character education is a foundational aspect of Islamic education, particularly at the primary level, where students begin to internalize moral and social values. In Indonesia, boarding-based madrasah institutions offer a unique environment for character formation due to their immersive and socially intensive settings. This study aims to explore the extent to which character-building strategies based on the sociology of education contribute to the character development of sixth-grade students at MIN 1 Banyumas, a state Islamic elementary school with a residential program. The theoretical framework draws from sociological theories emphasizing the role of structured social environments in shaping individual behavior and identity. The strategies examined in this study include daily habituation practices, exemplary modeling by educators and caregivers, value-based communication, and intentional peer interaction designed to reinforce shared norms and ethics. Methods: This research employs a quantitative associative design involving total sampling of all students living in the school’s dormitory. Data were collected using a Likert-scale questionnaire that had undergone tests for validity and reliability. The data were then analyzed using simple linear regression to determine the relationship between character-building strategies and character outcomes. Findings: The results reveal a statistically significant influence, with a p-value of 0.045 and an R-squared value of 0.136. These findings suggest that 13.6 percent of the variance in character development can be attributed to the implemented strategies. Conclusion: The study concludes that character formation in Islamic boarding environments benefits significantly from structured, socially embedded educational strategies. Novelty/Originality of this article: It calls for the institutionalization of sociologically grounded approaches to character education that are sensitive to students’ daily interactions, cultural context, and moral experiences.]]>

<![CDATA[This paper aims to analyze religious enthusiasm that does not continue after the primary school period is over and instead shows contrasting situations. Urban Muslims in Purwokerto, Indonesia, show high religious enthusiasm when choosing primary schools for their children. The number of public elementary school students has declined in the last five years, while Madrasah Ibtida'iyyah has increased dramatically. This research is field-type with data sources from urban Muslims who choose Madrasah Ibtida'iyyah as a primary school choice for their children. The data were analyzed qualitatively using a sociological approach. The study found that the religious enthusiasm of urban Muslims is pragmatic. Their pragmatic nature is shown by the resistance of different social groups that give rise to covert conflicts. In addition, they form new communities that actively represent them in public spaces. This finding has implications for a change in the perspective of the phenomenon of religious enthusiasm from theological awareness to a new trend of community-based urban Muslim pragmatism. Further research recommended the representation of the new identity of Muslim communities in virtual public spaces. Tulisan ini bertujuan menganalisis antusiasme keagamaan orang tua yang tidak berlanjut pada jenjang pendidikan setelah Sekolah Dasar dan justru menunjukkan situasi yang kontras. Muslim perkotaan di Purwokerto, Indonesia, menunjukkan antusiasme agama yang tinggi dalam memilih Sekolah Dasar untuk anak-anak mereka. Jumlah siswa Sekolah Dasar Negeri mengalami penurunan dalam lima tahun terakhir, sebaliknya Madrasah Ibtida'iyyah meningkat secara drastis.. Penelitian ini berjenis lapangan dengan sumber data dari kelompok muslim perkotaan yang memilih Madrasah Ibtida'iyyah sebagai pilihan sekolah dasar untuk anak-anak mereka. Data dianalisis secara kualitatif dengan menggunakan pendekatan sosiologis. Studi ini menemukan bahwa antusiasme keagamaan muslim perkotaan bersifat pragmatis. Sifat pragmatis mereka ditunjukkan melalui perlawanan dan menimbulkan konflik terselubung. Selain itu, mereka membentuk komunitas baru yang secara aktif merepresentasikannya di ruang publik. Temuan ini berimplikasi pada perubahan perspektif fenomena antusiasme keagamaan dari kesadaran teologis ke kecenderungan baru pragmatisme. Penelitian lebih lanjut merekomendasikan representasi identitas baru komunitas muslim di ruang publik virtual.]]>
