Jaring-jaring dapat membantu siswa membuat konsep hubungan antara objek dua dimensi dan tiga dimensi. Namun masih ada ketidakakuratan dalam menyusun jaring-jaring yang disebabkan oleh kemampuan spasial yang lemah. Tujuan dari penelitian ini adalah untuk menggambarkan kemampuan spasial siswa dalam membangun jaring-jaring kubus dan balok. Subjek penelitian adalah empat puluh siswa Sekolah Dasar kelas lima. Dari empat puluh siswa dipilih dua siswa untk diwawancara lebih mendalam terkait penyelesaian tugas jaring-jaring kubus dan balok. Hasil penelitian menunjukkan bahwa dalam menyelesaikan tugas penyusunan jaring-jaring kubus dan balok, subjek menunjukkan kelemahan dalam kemampuan orientasi spasial dan visualisasi spasial. Kelemahan pada orientasi spasial terlihat pada kemampuan subjek untuk melihat objek dari sudut pandang tertentu yaitu dalam mengenali dua jaring-jaring yang kongruen tetapi dianggap tidak kongruen. Sedangkan kelemahan visualisasi spasial nampak pada saat subjek yang tidak dapat membayangkan bahwa jaring-jaring dapat dilipat menjadi kubus dan balok. Nets can help students conceptualize the relationship between two-dimensional and three-dimensional objects. But there are still inaccuracies in composing the webs caused by weak spatial ability. The purpose of this study is to describe the spatial ability of students in constructing cube and beam webs. The research subjects were forty-fifth-grade elementary school students. Of the forty students, two students were chosen to be interviewed more deeply related to the completion of the task of the cube nets and the beam. The results showed that in completing the task of arranging cube and beam nets, the subject showed weaknesses in the ability of spatial orientation and spatial visualization. Weaknesses in spatial orientation are seen in the subject's ability to see objects from a certain point of view, namely in recognizing two nets that are congruent but considered incongruent while the weaknesses of spatial visualization are seen when subjects cannot imagine that the webs can be folded into cubes and blocks.

Mathematical disposition (MD) is widely recognized as a key factor influencing students’ performance, particularly in mathematical literacy (ML), which is emphasized in Indonesian education through the Asesmen Kompetensi Minimum (AKM), a national assessment focusing on literacy and numeracy. However, most studies rely on quantitative approaches, offering limited insight into how MD is enacted during problem-solving in classroom contexts. This study explores how MD is enacted by students with high ML when engaging in mathematical literacy tasks. Using a qualitative multiple-case study design, five senior high school students were purposively selected. Data were collected through written work, self-assessments, observations in individual and group settings, and two phases of interviews, and analyzed using thematic analysis. The findings reveal that MD emerges as a dynamic, context-sensitive system involving curiosity, confidence, persistence, flexibility, and reflection. Although all students produced correct solutions, their depth of engagement varied depending on how these dispositions were activated and regulated. Collaborative settings reshaped MD by redistributing confidence and enhancing participation, but also introduced challenges, such as reduced verification due to overreliance on group agreement. These findings suggest that ML provides the cognitive foundation for problem solving, while MD mediates its enactment. Keywords: Mathematical Disposition; Mathematical Literacy; Problem-Solving; Qualitative Study; Task-Based Learning.

High school students in Tarakan also experienced errors in integer operations, even though they should have mastered this material at an earlier level. This problem is closely related to classroom learning practices, especially the use of learning media that should facilitate cognitive engagement and meaningful learning experiences. Given the need for media, students' status as digital natives, and a survey showing that 67.2% of students are interested in adventure-themed comics, it is necessary to develop e-comics on integer operations material with adventure themes. The 4-D model development research was used by modifying it to 3-D (define, design, and develop). The research subjects consisted of six Year 10 students selected through purposive sampling. Data collection used qualitative and quantitative data obtained through observation, interviews, questionnaires, and documentation. Data analysis was conducted descriptively using a Likert scale to assess expert validity and student responses, with media feasibility criteria deemed feasible if they achieved a minimum percentage of 61%. The validation results showed that the media met the feasibility criteria, with material and language expert assessments of 91.25% and media and language expert assessments of 90.79%, both of which were classified as highly feasible. Limited trials involving six students with diverse abilities showed positive responses with a feasibility percentage in the feasible category. Thus, e-comic media with an adventure theme are feasible for use as learning media for tenth-grade students. Keywords: Adventure Theme, E-comics, Integer Counting Operations, Learning Media. Kesalahan dalam operasi bilangan bulat juga dialami siswa Sekolah Menengah Atas di Tarakan, padahal seharusnya materi tersebut telah dikuasai di jenjang sebelumnya. Permasalahan tersebut berkaitan erat dengan praktik pembelajaran di kelas, terutama dengan pemanfaatan media pembelajaran yang seharusnya dapat memfasilitasi keterlibatan kognitif dan pengalaman belajar bermakna. Penggabungan kebutuhan media, karakteristik siswa sebagai digital natives, dan hasil survey 67,2% siswa tertarik pada komik bertemakan petualangan. Sehingga diperlukan pengembangan media e-comic dengan tema petualangan pada materi operasi bilangan bulat. Penelitian pengembangan model 4-D digunakan dengan memodifikasi menjadi 3-D (define, design, dan develop). Subjek penelitian terdiri dari 6 siswa kelas X yang dipilih melalui teknik purposive sampling. Pengumpulan data menggunakan data kualitatif dan kuantitatif yang dilakukan melalui observasi, wawancara, angket, dan dokumentasi. Analisis data dilakukan secara deskriptif menggunakan skala Likert untuk menilai validitas ahli dan respon siswa, dengan kriteria kelayakan media yang dinyatakan layak apabila mencapai persentase minimal 61%. Hasil validasi menunjukkan bahwa media memenuhi kriteria kelayakan, dengan penilaian ahli materi dan bahasa sebesar 91,25% serta ahli media dan bahasa sebesar 90,79%, keduanya termasuk kategori sangat layak. Uji coba terbatas terhadap enam siswa dengan karakteristik kemampuan yang beragam menunjukkan respons positif dengan persentase kelayakan pada kategori layak. Sehingga, media e-comic dengan tema petualangan layak digunakan sebagai media pembelajaran bagi siswa kelas X. Kata kunci: E-comic, Media Pembelajaran, Operasi Hitung Bilangan Bulat, Tema Petualangan
