Technology-based learning media is still lacking for special needs students in mathematics. Based on observations and interviews with Special School (SLB) teachers, the learning media used were still monotonous, such as picture books and writing using a blackboard. This research aims to develop e-comic math using the App Pixton application, which is valid and practical for children with special needs in SLB. The research method used is Plomp model development research in the prototype development phase: self-evaluation, expert review, and one-to-one evaluation. The data collection instruments used were a questionnaire and mathematical concepts on addition and subtraction topics for students with special needs. The research subjects were 21 students and 5 teachers from 5 different special schools in 5 West Sumatra, Indonesia cities. The study results show that the media developed is valid and practical for students with deaf and intellectual disabilities. This research implies that teachers must be able to develop other IT-based learning media to help students with special needs learn mathematics like normal children.

This study examines the beliefs and attitudes of high school mathematics teachers toward TPACK-oriented technology integration through the development of interactive teaching materials using Genially in Pesisir Selatan Regency. TPACK orientation is positioned as the foundation for integrating technological knowledge and mathematical content knowledge in the development of digital teaching materials. The study used a survey method with twenty mathematics teachers as participants. Data were collected through belief questionnaires, attitude questionnaires, and structured interviews to explain the reasons behind the questionnaire responses. Belief indicators include teachers' views on learning and knowledge for learning related to technology engagement. Attitude indicators include familiarity, interest, efforts to seek help when experiencing difficulties with features, and the desire to use Genially to support students' mathematical problem-solving during learning. The results showed very high acceptance of the use of technology, especially the Genially application (94–95% agreement on key indicators). Interviews confirmed that Genially's visual interactivity helps teachers explain abstract concepts and relate the material to real-life contexts, but internet stability and initial design time remain obstacles. These findings support Quality Education (SDG 4) by strengthening teachers' readiness to integrate technology in mathematics learning.

Mathematical reasoning is one of the essential competencies that students must possess to face the challenges of 21st-century learning. However, many students still struggle to solve problems that assess their mathematical reasoning. This study aims to analyse the types of errors students make using Newman’s Error Analysis procedure. The research employed a descriptive qualitative method, with 37 twelfth-grade high school students selected through purposive sampling. Data were collected through a mathematical reasoning ability test and interviews. The quantitative data from the test were analysed descriptively to identify error patterns, while the qualitative data from interviews were analysed thematically through data reduction, data display, and conclusion drawing. Most students made errors in three main stages, namely understanding the problem concept, transforming verbal information into appropriate mathematical representations, and applying mathematical procedures or algorithms correctly. Furthermore, the analysis showed that conceptual misunderstanding was the most prevalent type of error, often leading to subsequent transformation and process-skill errors. These findings suggest that teachers need to design learning interventions that strengthen conceptual comprehension and develop students’ systematic problem-solving strategies.

This study focuses on the professionalism of teachers, particularly in terms of their attitudes and beliefs toward the integration of digital technology in teaching and learning activities. Plotagon was selected as a medium for developing interactive and contextual 3D instructional videos. The research employed a survey method aimed at exploring teachers’ interest in and acceptance of Plotagon as a supportive tool for instructional materials. The participants comprised twenty-eight junior high school teachers in Sawahlunto City. Prior to the survey, the teachers received intensive training on creating instructional videos using Plotagon. Data were collected through direct observation, questionnaires, and structured interviews. The findings reveal that the majority of teachers (91%) demonstrated positive beliefs regarding the use of digital culture-based technology through Plotagon, while 88% considered the medium beneficial for students. Furthermore, 86% of teachers showed high levels of engagement, and an equal proportion actively participated throughout the implementation process. These results imply that integrating digital storytelling platforms such as Plotagon can enhance teachers’ professional competence and foster innovative teaching practices.

Abstract: Mathematical communication is an essential competency in mathematics learning; however, the mathematical communication skills of Grade VIII students at SMP Negeri 25 Padang were still relatively low. This study aimed to describe the development of students' mathematical communication skills during the implementation of the Think Talk Write (TTW) cooperative learning model and to determine whether these skills were better than those of students who learned through conventional instruction. This study employed a quasi-experimental method using a nonequivalent posttest-only control group design. The research samples were Class VIII.6 as the experimental group and Class VIII.7 as the control group. Data were collected through quizzes and an essay-based mathematical communication skills test. The results showed that the mathematical communication skills of students in the experimental class improved progressively throughout the implementation of the TTW learning model. The Mann–Whitney test at a significance level of 0.05 yielded a p-value of 0.000, leading to the rejection of H₀. Therefore, students who learned through the Think Talk Write cooperative learning model demonstrated better mathematical communication skills than those who received conventional instruction. Keyword: mathematical communication skills; cooperative learning model; think talk write. Abstrak: Kemampuan komunikasi matematis merupakan salah satu kompetensi penting dalam pembelajaran matematika, namun kemampuan tersebut pada peserta didik kelas VIII SMP Negeri 25 Padang masih tergolong rendah. Penelitian ini bertujuan untuk mendeskripsikan perkembangan kemampuan komunikasi matematis peserta didik selama diterapkan model pembelajaran kooperatif tipe Think Talk Write (TTW) serta mengetahui perbedaannya dengan peserta didik yang belajar menggunakan pembelajaran konvensional. Penelitian menggunakan metode eksperimen semu (quasi experiment) dengan rancangan nonequivalent posttest-only control group design. Sampel penelitian terdiri atas kelas VIII.6 sebagai kelas eksperimen dan kelas VIII.7 sebagai kelas kontrol. Data dikumpulkan melalui kuis dan tes kemampuan komunikasi matematis berbentuk soal uraian. Hasil penelitian menunjukkan bahwa kemampuan komunikasi matematis peserta didik pada kelas eksperimen mengalami peningkatan secara bertahap selama penerapan model TTW. Hasil uji Mann-Whitney pada taraf signifikansi 0,05 menghasilkan p-value = 0,000 sehingga H₀ ditolak. Dengan demikian, kemampuan komunikasi matematis peserta didik yang belajar menggunakan model pembelajaran kooperatif tipe Think Talk Write lebih baik daripada peserta didik yang belajar menggunakan pembelajaran konvensional. Kata kunci: kemampuan komunikasi matematis; model pembelajaran kooperatif; think talk write.
