Abstract

In solving problems and generating new ideas in mathematics, creativity is needed. However, the facts in Indonesia show that students' mathematical creativity is still in the low category. This situation is suspected because in Indonesia, students are less accustomed to solving open-ended problems to train their thinking skills. In addition, the availability of open-ended problems is still limited, making it difficult for teachers to provide open-ended problems for students. This research produced valid and practical open-ended questions to measure and even improve students' mathematical creativity. The research method applied was formative research development model (preliminary, self evaluation, prototyping, field test). Field test was conducted on 32 students of class VIII SMP Negeri 1 Sungai Raya. The developed open-ended questions successfully measured students' mathematical creativity on fluency, flexibility, and novelty indicators. The development results showed that the open-ended questions made were valid and practical, with 96.875% of students reaching the positive category towards the developed open-ended questions. Thus, the designed open-ended questions function well in measuring and even improving students' mathematical creativity.

Abstract

This study used qualitative research and descriptive approach in accordance with the research objectives, namely describing the perceptions of elementary school teachers towards numeracy literacy in the context of traditional Madurese games. The instruments used were questionnaire of teachers' initial understanding, problem posing test and interview guideline. The questionnaire is used to find out the teacher's initial understanding of numeracy literacy and ethnomathematics and its implementation in learning, the problem possing test is used to see the teacher's ability to design numeracy literacy questions in the context of traditional Madurese games, and interviews are used to strengthen the data from filling out questionnaires and problem possing tests. The subjects in this study were grade 4, 5 and 6 teachers in elementary schools located in rural and urban areas. The results showed that there is no difference in understanding between rural and urban teachers regarding numeracy literacy, they can understand numeracy literacy and usually implement it in learning. However, for ethnomathematics, rural teachers cannot understand, both rural and urban teachers have never implemented ethnomathematics in learning. Finally, neither rural nor urban teachers can design numeracy literacy questions in the context of traditional Madurese games

Abstract

Mathematics, essential for fostering problem-solving skills, plays a critical role in education. However, the lack of creativity and flexibility among students in solving complex problems like ill-structured problems (ISPs) in exponential material indicates significant learning obstacles. This study aimed to identify and analyze the learning obstacles faced by senior high school students and explore their creative mathematical thinking abilities when addressing ISPs in exponents. Employing a qualitative descriptive method with a Didactical Design Research (DDR) framework, data were gathered through tests, observations, and semi-structured interviews. The study involved 40 purposively selected tenth-grade students from Bandung. Findings reveal that students excel in fluency but struggle with flexibility and originality. Learning obstacles include ontogenic (limited conceptual understanding), didactic (restricted instructional variety), and epistemological (context-dependent reasoning). These obstacles impede students' creative thinking development, especially in producing unique solutions and utilizing alternative approaches. The study concludes that addressing these obstacles requires innovative teaching strategies, such as problem-based learning and didactical designs emphasizing exploration and creativity. These strategies can enhance creative thinking in mathematics, benefiting students' adaptability in academic and real-world challenges. Future research should focus on implementing and refining such designs across various mathematical topics.

Abstract

Teaching critical thinking in mathematics classroom is challenging. Mathematics teachers need a strong foundation of subject matter knowledge (SMK) to be able to design and conduct a mathematics lesson focuses on critical thinking. However, this knowledge was found low among the teachers. A community learning play important role in overcome teacher problems. One of community learning plafform that can be used to facilitate teacher to strengthen their SMK is a school-university partnership mediated by lesson study (SUPER-LS) program. Thus, this study used the SUPER-LS program to facilitate mathematics teachers to develop their subject matter knowledge (SMK) and students critical thinking. The qualitative approach was used in this study involving 10 in-service teachers (ISTs) and 59 students. Lesson study artefacts were employed to collect data and analyzed using transcrib based lesson analysis and performance assessment of critical thinking scale. The study discovered that the SUPER-LS program can facilitate collaboration among ISTs to develop and strengthen their SMK with specialize content knowledge (SCK) appear dominant. In addition, students proficiency in each indicator of critical thinking ranged from level 1 to level 4. The majority of students had a proficiency level of 2 in each indicator. However, sustain SUPER-LS program is required to improve students critical thinking performance.

Abstract

This study explores elementary school teachers' understanding of the concept of number and arithmetic operations through a phenomenological approach. The purpose of this study is to explore and understand teachers' subjective experiences in interpreting and teaching these concepts, and to emphasize the importance of individual perspectives in shaping their understanding. Teachers' subjective experiences are considered crucial because they influence the way they teach and explain mathematical concepts to students, as well as shaping students' concept images. This study involved 10 elementary school teachers who were selected using purposive sampling techniques to ensure diversity in experience and educational background. Data analysis was conducted using the phenomenological thematic analysis method to identify key themes and patterns in teachers' experiences. The findings of the study revealed significant differences between teachers' understanding and scientific conceptions, referred to as Zone Concept Image Differences (ZCID). The conclusion of this study shows that teaching the concept of number and arithmetic operations is often constructed narrowly, thus not supporting the development of broader thinking in students.

Abstract

This study aims to explore students' commognitive processes in solving linear programming problems based on their learning styles. Conducted with three female students from Class XI MIPA 4 at SMAN 5 Palu, the study included one student each with visual, auditory, and kinesthetic learning styles. Data collection involved administering a learning style questionnaire and linear programming tasks (SBMPTN 2014 Code 663) that were linguistically validated to suit the students in Palu. Interviews were also conducted while the students worked on these tasks. Results indicate that the visual learner responded to problems in a detailed, repetitive, efficient, and accurate manner, demonstrating all four commognitive indicators. The main finding was the student's clear process in visualizing the problem. The auditory learner also responded well, demonstrating the four commognitive indicators but faced difficulties in the routine aspect, especially in transforming the problem into a narrative form, which is crucial for problem-solving. The kinesthetic learner showed clear, accurate responses and exhibited all four commognitive indicators, with a notable habit of using finger-pointing during explanations. However, limitations were observed in the narrative aspect, where the student relied more on physical experience than on logical, in-depth explanation.

Abstract

The integration of Virtual Reality (VR) and Artificial Intelligence (AI) in STEM-based mathematics learning offers significant potential to enhance students' comprehension of abstract concepts. This study aims to identify key infrastructure and technology readiness challenges and propose practical solutions. Using a qualitative research design, data were collected through in-depth interviews with ten teachers and 85 students from secondary schools and analyzed thematically. The results highlight three primary barriers: limited internet access, high hardware costs, and insufficient technical training. While students showed enthusiasm toward VR and AI, teachers expressed a lack of preparedness to utilize these technologies. Furthermore, the digital divide between urban and rural schools aggravates educational inequities. To address these challenges, the study recommends increased investment in digital infrastructure, provision of hardware subsidies, and continuous teacher training programs. Collaboration between the government and private sector is also essential to bridge gaps and support the effective implementation of VR and AI in education. This research contributes by offering insights and actionable strategies for integrating emerging technologies in STEM education, ultimately improving learning outcomes and reducing educational disparities.
