Abstract

Higher Order Thinking Skills of students in Indonesia, including students in Papua, are still very low. On the other hand, Papua's nature and culture have the potential to be used as an instrument or context in developing questions that can develop students' Higher Order Thinking Skills (HOTS), especially in mathematics learning. This study aims to create and analyze HOTS questions based on nature and culture. The products developed were HOTS items, with the procedure for determining the context, expanding the items, testing the items' validity, and further analysis. The results showed that HOTS mathematics questions could be developed using Papua's Nature and Culture context. These results contribute to inspiring educators and other researchers to establish HOTS questions based on Papua's nature and culture, both in mathematics and other subjects.

Abstract

Due to the poor instruction process during the Covid-19 Pandemic, especially in mathematics, students frequently need help with data literacy. To overcome these obstacles, they must improve their thinking skills. This study aims to enhance the quality of mathematics instruction, especially students' thinking skills, by implementing Lesson Study to develop sharing and jumping tasks. This qualitative descriptive research was conducted at one of the senior high schools and universities in Manokwari, West Papua, with their students as the research subject. The lesson study was implemented in two cycles through instruction at school and lectures at the university. The lesson study consists of three processes: plan, do, and see. The hypothetical learning trajectory was developed at the lesson design stage and then tested at the teaching-learning stage. The open class results were then analyzed during the reflection step to redesign the sharing and jumping tasks. The success of the research was determined through field notes taken from teachers and students. The frequency distribution table is used as the topic matter. The findings revealed that students' thinking skills developed, indicating they were more interested than in the previous teaching and learning process. The learning process was more exciting and enhanced conceptual comprehension. Because learning was communicable, students were more satisfied. They were more engaged and required further thought to comprehend the topic matter. Also, they produce a variety of responses, which is only feasible if they are capable of critical thought.

Abstract

Research on mathematical self-efficacy and creative thinking has grown in recent years. However, studies examining their interaction in fostering mathematical creativity remain limited. Understanding this relationship is crucial, as self-efficacy influences students’ responses to open-ended challenges and their ability to generate creative solutions. This research gap is particularly relevant in the context of Papua, where cultural and contextual factors shape students' thinking patterns and problem-solving strategies. This study investigates the relationship between students’ mathematical self-efficacy and their creative problem-solving ability within the context of social arithmetic, an area often underexplored. Anchored in Bandura’s social cognitive theory, self-efficacy is conceptualized as a key psychological construct that influences student engagement, strategy use, and persistence in mathematical tasks. Employing a descriptive-exploratory design with embedded qualitative insights, this study involved 72 eighth-grade students from West Papua. Data were collected through a validated Likert-scale questionnaire, open-ended problem-solving tasks based on Torrance’s creativity framework, and semi-structured interviews analyzed thematically. Results show that 52.8% of students had moderate self-efficacy, while 25% were classified as high. In creative problem-solving, students excelled in fluency and elaboration but struggled with originality and flexibility. A strong positive correlation was found between self-efficacy and creative thinking (ρ = 0.849, p < 0.001). These findings underscore the importance of designing instructional strategies that enhance both confidence and cognitive flexibility through contextualized, open-ended, and collaborative learning environments. .

Abstract

The integration of technology in education has revolutionized various disciplines, and mathematics education is no exception. This paper explores the digital transformation of ethnomathematics, a field that connects mathematical concepts with cultural practices, and how this intersection can be enhanced through the use of modern technological tools. By leveraging technology, the study aims to preserve and promote cultural heritage while simultaneously improving mathematical learning outcomes. Through the development of interactive digital tools, such as augmented reality (AR) and virtual reality (VR) applications, the paper demonstrates how indigenous knowledge systems and cultural representations can be seamlessly incorporated into mathematics curricula. The integration of these tools not only makes learning more engaging but also fosters a deeper connection between students and the cultural contexts in which mathematical ideas originate. Furthermore, the study highlights the significance of ethnomathematics in fostering cultural awareness and appreciation among students while encouraging critical thinking and problem-solving skills. The paper concludes by discussing the implications of this digital transformation in ethnomathematics for both educators and students, providing a pathway for the future of culturally relevant mathematics education in the digital age.

Abstract

The STEM-Robotics training at YPPK St. Thomas Aquino Junior High School in Kaimana, West Papua, was conducted to address teachers' low understanding of STEM and coding concepts and the suboptimal utilization of robotics facilities in schools. This program aims to improve teachers' understanding of STEM learning, coding competency, and attitudes toward the implementation of STEM-Coding. The program was implemented using a service-learning approach involving 28 teachers, 4 lecturers, and 3 students across five stages: needs identification, collaborative planning, practice-based implementation, critical reflection, and evaluation. Data were collected using a validated questionnaire and analyzed descriptively. The training results showed that teachers' understanding of STEM learning reached 52% in the moderate category and 48% in the high category. Teachers' understanding of coding reached 4% in the moderate category and 96% in the high category. In comparison, positive attitudes toward STEM-Coding learning reached 11% in the moderate category and 89% in the high category. Overall, all program success indicators were met, with more than 85% of teachers in the moderate-to-high category across all measured aspects. This program is effective in improving teacher competency and supporting the development of technology-based learning in areas with limited access to education.

Abstract

Abstract In today’s data-driven era, the rapid growth of big data has made encounters with data unavoidable for everyone, including students. Therefore, preparing students with adequate statistical literacy has become increasingly important. This study employed a quantitative non-experimental design using an ex post facto approach. It examined and compared students' statistical literacy across three types of schools in Aceh, Indonesia. More specifically, the study investigated whether school type predicted students' statistical literacy after controlling for gender and parental education. Data were collected through a statistical literacy test and a brief demographic questionnaire covering gender and parental educational background. The data were analyzed using hierarchical multiple regression and Tukey HSD post hoc analysis. The findings showed that gender and parental education did not significantly influence students' statistical literacy, whereas school type did. These results suggest that different school environments may offer distinct learning experiences and opportunities for statistical reasoning and data literacy. Abstrak Di era berbasis data saat ini, pertumbuhan big data yang semakin pesat membuat setiap individu, termasuk siswa, tidak dapat terlepas dari paparan data dalam kehidupan sehari-hari. Oleh karena itu, mempersiapkan siswa dengan kemampuan literasi statistik yang memadai menjadi semakin penting. Penelitian ini menerapkan desain penelitian kuantitatif non-eksperimental dengan pendekatan ex post facto. Penelitian ini bertujuan untuk mengkaji dan membandingkan literasi statistik siswa pada tiga jenis sekolah di Aceh. Secara khusus, penelitian ini meneliti apakah jenis sekolah memprediksi literasi statistik siswa setelah mengontrol gender dan pendidikan orang tua. Data dikumpulkan melalui tes literasi statistik dan kuesioner singkat terkait gender serta latar belakang pendidikan orang tua. Data dianalisis menggunakan hierarchical multiple regression dan uji lanjut Tukey HSD. Hasil penelitian menunjukkan bahwa gender dan pendidikan orang tua tidak berpengaruh signifikan terhadap literasi statistik siswa, sedangkan jenis sekolah menunjukkan pengaruh yang signifikan. Temuan ini mengindikasikan bahwa lingkungan sekolah yang berbeda dapat memberikan pengalaman belajar dan kesempatan yang berbeda pula dalam mengembangkan kemampuan penalaran statistik dan literasi data siswa.
