The emergence of various problems during online learning must receive attention, especially for special needs students. For deaf children, online learning problems in mathematics lessons will become more complex due to communication barriers (hearing loss). This study aims to analyze deaf children's mathematical anxiety in learning mathematics and its correlation to the deaf children’s learning outcomes during the Covid-19 pandemic. This research was descriptive and correlational research types. The subject research was deaf children at the SMP Luar Biasa Negeri Tuna Rungu. The study sample was 24 students. Research data was collected by observation, interviews, questionnaires, and tests. The data analysis used was descriptive analysis and simple regression. The results showed that deaf children's mathematical anxiety was very high. The results of the regression analysis show that mathematical anxiety has a significant effect on mathematics learning outcomes. Even though online learning during the pandemic has made the implementation of mathematics learning flexible because it can accommodate different learning styles of children, many obstacles were found in the learning process, given the limitations of deaf children, and they preferred offline learning. The implications of this research are expected to be an evaluation for teachers and deaf children to improve mathematics learning outcomes and to overcome deaf children's mathematical anxiety.

The integration of Computational Thinking (CT) into mathematics learning has become a key demand in 21st-century education, as it plays an important role in developing logical, creative, and systematic thinking skills. However, in the context of Indonesian education, implementing CT still faces various challenges, particularly regarding teachers’ understanding and readiness to integrate it into the learning process. This study aims to explore teachers’ perspectives on CT-based mathematics learning, including their understanding, perceived relevance, readiness, and the challenges they face in its implementation at the junior high school level. This study offers a novel contribution by explicitly distinguishing between teachers’ conceptual understanding of CT and their pedagogical readiness to implement CT in mathematics learning, a gap that has been insufficiently explored in previous studies. The study employed a qualitative approach with an exploratory design. The research population consisted of junior high school mathematics teachers in Singaraja City, Indonesia. Eight teachers were selected as research participants using purposive sampling based on criteria such as teaching experience, involvement in CT-related or technology-based learning, and willingness to participate in the study. Data were collected through semi-structured interviews, classroom observations, and analysis of learning documents, then analyzed inductively through the stages of data reduction, data presentation, and conclusion drawing. The results showed that the teachers’ perspectives on CT-based mathematics learning are conceptually positive but still limited in practice. CT is considered relevant and potentially effective in strengthening mathematical thinking skills; however, its implementation requires systematic support. Based on these findings, the study recommends providing continuous, practice-oriented professional development programs for teachers, developing CT-based mathematics teaching resources, and stronger policy support to facilitate the effective integration of CT into junior high school mathematics learning. The study's implications highlight the importance of strategies to strengthen teachers’ capacity.

Researchers systematically examine the profile and characteristics of students' computational thinking abilities when they tackle math problems in algebra and geometry, as computational thinking counts as one of the key competencies in 21st-century math learning that bolsters students' problem-solving skills. This study uses a Systematic Literature Review (SLR) and reviews articles published between 2015 and 2025, so researchers search those articles in databases like Google Scholar, Scopus, ERIC, SpringerLink, and DOAJ with keywords linked to computational thinking and math learning. They base the selection process on inclusion and exclusion criteria, which leads to 12 relevant articles ready for analysis. The results show students' computational thinking skills marked by four main aspects decomposition, pattern recognition, abstraction, and algorithmic thinking and its use in algebra and geometry learning happens via problem-based approaches, algorithmic representations, as well as visualization and simulation activities. Decomposition and algorithmic thinking emerge as the dominant aspects students use, whereas abstraction and pattern recognition pose the biggest challenges, particularly in geometry, and these insights point to the need for more systematic design in blending computational thinking into math learning to strengthen abstraction and pattern recognition so students improve their math problem solving quality.
