Abstract

Abstract: The development of technology flows is increasing. The internet, which was initially used by several groups as a medium for the transformation of scientific and academic data, has now been used in almost all aspects of people's lives, including e-commerce transactions. E-commerce transactions are transactions carried out without meetings between parties. By using e-commerce, many reservations are obtained from the seller or buyer. The convenience offered doesn't mean it doesn’t rise the problems. For Muslims, understanding the status of e-commerce transactions is important. E-commerce accepts payments with bai’s-salam, which is about non-related transactions and the suspension of goods for payments that have been hastened. It's just that if on Bai 's-Salam a face-to-face meeting is held for the implementation of sighat, it is different with e-commerce that communicate only through chat. E-commerce is permitted in Islam with a note that there is no riba ',gharar, maisir, etc. Therefore, if it is approved by the payment system on e-commerce, it is asked not to use a credit card to avoid riba’.الملخص: يشهد تطوير تدفقات التكنولوجيا زيادة هائلة. يستخدم الإنترنت في جميع جوانب حياة الناس تقريبًا ØŒ بما في ذلك معاملات التجارة الإلكترونية، معاملات التجارة الإلكترونية هي معاملات تتم بدون اجتماع بين الطرفين .باستخدام التجارة الإلكترونية، الكثير من السهولة حصلت من البائع أو المشتري. يتم تقديم التسهيلات المقدمة. التسهيلات المقدمة لايمكن تسبب مشاك. معلومات المسلمين عن حالة المعاملة التجارة الإلكترونية شيء مهمة. التجارة الإلكترونية مثل بيع السلام هي عن العناصر فى المعاملات وتأخير القبض دفعت مقدما. إذا كان بيع السلام يتم عقد اجتماع وجها لوجه في تنفيذ سيغات تختلف عن التجارة الإلكترونية استخدام التواصل مع الدردشة. التجارة الإلكترونية مباحات في الإسلام مع ملاحظة عدم وجود عناصر الربا والغرار والميسر وغيرها لذلك ØŒ إذا كانت مرتبطة بنظام دفع في التجارة الإلكترونية المستحسن عدم استخدام بطاقة الائتمان لتجنب الربا.. Abstrak: Perkembangan arus teknologi mengalami peningkatan yang masif. Internet yang pada awalnya digunakan oleh beberapa kalangan sebagai media transformasi data ilmiah dan akademik, kini telah digunakan di hampir seluruh aspek kehidupan masyarakat, termasuk transaksi jual beli (e-commerce). Transaksi e-commerce merupakan transaksi yang dilakukan tanpa adanya pertemuan antar para pihak. Dengan menggunakan e-commerce, banyak kemudahan yang diperoleh baik dari pihak penjual maupun pembeli. Kemudahan yang ditawarkan bukan berarti tidak menimbulkan masalah. Bagi kaum muslim, mengetahui status dari transaksi e-commerce merupakan hal yang penting. E-commerce  memiliki kesamaan dengan bai’ as-salam yaitu mengenai unsur-unsur terjadinya transaksi serta adanya penangguhan barang untuk pembayaran yang telah disegerakan. Hanya saja, jika pada bai’ as-salam dilakukan pertemuan face to face untuk pelaksanaan sighat, berbeda halnya dengan e-commerce yang melakukan komunikasi via chatting. E-commerce diperbolehkan dalam Islam dengan catatan tidak adanya unsur riba’, gharar, maisir, dsb. Oleh karena itu, jika dihubungkan dengan sistem pembayaran pada e-commerce, maka dianjurkan tidak menggunakan kartu kredit guna menghindari terjadinya riba’.

Abstract

Mathematics is the study of patterns, so in chess pattern recognition is very important in problem solving. Chess is a problem-solving instrument and the best way to analyze problem-solving because chess has clear rules in decision making, thus a skilled chess player becomes a good problem solver. Metacognitive activity and problem-solving processes are intimately intertwined. The purpose of this research is to describe the metacognition profiles of students who play chess and students who do not play chess in solving mathematical problems. This research is a qualitative-research. The research subjects in this study were students who could play chess and students who could not play chess. The criteria are students who have participated in chess matches as low as possible at the sub-district level and regularly play chess, while students who cannot play chess are students who do not understand the basics of playing chess. This research carried out in class VIII at a junior high school in Surabaya. The instruments in this study were math ability tests, problem-solving tests and interview guidelines. The data collection procedure was carried out by giving students a math problem-solving test and interviews. The data analysis technique in this study was carried out in the following steps; transcribing the subject's answers, examining the subject's answer data from interviews, data reduction, data categories, analyzing students' metacognition profiles, and drawing conclusions. The results of the study stated that the metacognitive abilities in solving problems of chess students were better than those of non-chess students. The ES subject achieved 80% of metacognitive activity indicators, while the MI subject only achieved 54.25% of metacognitive activity indicators.

Abstract

Research on mathematical identity has increasingly gained attention within the field of mathematics education. However, studies examining the mathematical identity of prospective mathematics teachers, particularly in relation to gender differences, remain limited. This study aims to investigate whether mathematical identity differs between male and female prospective mathematics teachers, focusing on aspects of interest, recognition, competence, performance, and beliefs about mathematics. A quantitative approach was employed using a questionnaire to collect data, which were analyzed using the Mann–Whitney statistical test. The findings indicate significant gender-based differences in the mathematical identity of prospective mathematics teachers across all measured components. These results provide a foundation for mathematics educators to consider instructional models that can positively shape and support the development of mathematical identity among future mathematics teachers.

Abstract

Mathematical identity has become a significant focus in mathematics education research because it influences how individuals perceive themselves as learners and practitioners of mathematics. Theoretical perspectives, including socio-cultural and discourse-based views, suggest that mathematical identity is constructed through personal experience, community recognition, and participation in mathematical practices. However, empirical research on the mathematical identity of prospective mathematics teachers remains limited, particularly studies that quantitatively examine the multiple components of identity before students enter the teaching profession. Addressing this gap, the present descriptive quantitative study investigates the mathematical identity of prospective mathematics teachers. A total of 88 participants completed the questionnaire on mathematical identity, which consisted of 18 items covering interest, recognition, competence, performance, and beliefs about mathematics. The responses were analyzed using descriptive statistical methods, including frequency distributions, mean scores, and categorical classifications. The results showed that 70.45% of prospective mathematics teacher students had a high mathematical identity. Component-level analysis revealed that 78.41% had high interest in mathematics, 55.68% had medium levels of recognition, 48.86% showed high competence beliefs, 92.04% scored high in performance beliefs, and 97.73% held strong positive beliefs about the nature of mathematics. This study contributes to the literature by providing a detailed quantitative profile of mathematical identity among prospective mathematics teachers. The findings suggest that teacher education programs should intentionally design learning environments that provide more opportunities for constructive feedback. Future research should examine the factors that shape and influence the development of mathematical identity, particularly through longitudinal or mixed-method approaches that can capture changes over time and provide deeper explanatory insights.
