Abstract

Mathematical representation is a crucial skill that enables students to express, interpret, and connect mathematical concepts through visual, symbolic, and verbal forms. This study explores the differences in mathematical representation skills between students with reflective and impulsive cognitive styles in solving two-variable linear inequality system problems. Using a qualitative descriptive approach, four high school students were selected based on their cognitive styles through the Matching Familiar Figure Test (MFFT). Data were collected through problem-solving tasks and semi-structured interviews. The findings indicate that reflective students demonstrate strong mathematical representation abilities, particularly in organizing and translating information across visual, symbolic, and verbal representations. They exhibit a structured and analytical approach to problem-solving, ensuring accuracy and coherence in their representations. In contrast, impulsive students struggle with problem organization, symbolic representation, and verbal explanation, often producing incomplete and less structured representations due to their tendency to prioritize speed over accuracy. These results highlight the influence of cognitive style on mathematical representation and suggest the need for tailored instructional strategies. Future research should expand the study to a broader mathematical scope and implement targeted interventions to enhance students' representation skills according to their cognitive characteristics.

Abstract

This study aims to analyze the effectiveness of using Langsa City folklore, translated from Indonesian into English, in enhancing children’s English learning outcomes. The research background stems from students’ low motivation and limited English proficiency, as well as the need for contextual and culturally relevant learning media. The study employed a quasi-experimental design involving two groups: the experimental group (n=30), which received instruction using translated folklore, and the control group (n=30), which followed conventional learning methods. Data were collected through pre- and post-tests of English competence, learning motivation questionnaires, and interviews with teachers and students. The findings indicate a significant improvement in the experimental group compared to the control group, both in English proficiency (p < 0.001) and learning motivation (? = +0.9). Qualitative analysis revealed that students were more enthusiastic and engaged with the material due to its familiar cultural values. The main challenges included limited time and difficulty in translating certain cultural vocabulary directly. Overall, the study concludes that translated Langsa folklore is an effective medium to enhance students’ learning outcomes and motivation in English language education. The implications emphasize the importance of developing local wisdom-based teaching materials to support foreign language learning in secondary schools.

Abstract

Higher-order thinking skills (HOTS) are essential in fostering students' critical and creative problem-solving abilities, particularly in mathematics. This study aims to determine the level of difficulty students face in solving HOTS-based mathematics problems. This qualitative descriptive study was conducted at SMPN 1 Latambaga with 23 eighth-grade students (class VIII A) as participants. The instruments, comprising tests and interviews, were constructed based on three indicators of HOTS: analyzing, evaluating, and creating. From the participants, six students were selected to represent three ability levels: high, moderate, and low. Students in the high category met all HOTS indicators. Moderate-level students achieved analyzing and evaluating but struggled with the creating aspect. Low-level students were only able to analyze and faced difficulties in evaluating and creating solutions. Their challenges included misapplication of principles, procedural errors, and verbal misunderstandings of question instructions. The findings highlight the need for targeted strategies to enhance students' critical and creative thinking in solving contextual and open-ended mathematics problems.

Abstract

Penelitian ini dilatarbelakangi oleh rendahnya minat belajar siswa terhadap materi refleksi yang memerlukan keterampilan visualisasi. Pembelajaran yang masih didominasi oleh metode konvensional menyebabkan siswa kurang terlibat secara aktif sehingga dibutuhkan inovasi media yang dapat memberikan pembelajaran interaktif. Penelitian ini bertujuan untuk mengetahui Tingkat kevalidan dan kepraktisan media yang dikembangkan serta mendeskripsikan minat belajar siswa setelah menggunakan media pembelajaran berbasis GeoGebra. Penelitian ini merupakan studi penelitian dan pengembangan yang menggunakan model ADDIE yang mencakup tahap analisis, desain, pengembangan, implementasi, dan evaluasi. Subjek penelitian Adalah 27 siswa kelas XI di SMAN 1 Latambaga. Data diperoleh melalui lembar validasi ahli, angket respon siswa, dan angket minat belajar. Hasil validasi menunjukkan bahwa media berada dalam kategori sangat valid dengan persentase 95%. Praktikalitas media berdasarkan respon siswa mencapai 92% dengan kategori sangat praktis. Minat belajar siswa berada pada kategori sangat tinggi dengan persentase sebesar 85%. Dengan demikian, media pembelajaran berbasis GeoGebra yang dikembangkan dapat dikatakan valid, praktis dan mampu menarik minat belajar siswa pada materi refleksi (pencerminan).
