Fraction is one of the difficult topic for students. One way to reduce students’ difficulties is to implement Realistic Mathematics Education (RME) by integrating Islamic values such as Sacrifice Worship (Ibadah Kurban). In addition, the use of technology to integrate sacrificial worship in fraction learning is also expected to increase students' interest in learning in the 21st century and can improve students' understanding. Therefore, it is necessary to develop an e-module for learning fractions through RME with the context of Sacrifice worship. The developed e-module contains learning trajectories, live worksheets, videos, and post-tests. This type of research is research and development which follows the stages of Plomp, especially in the prototyping and assessment stages. The instruments in this study were validation sheets. The validators consisted of one mathematics education lecturer and two Banda Aceh City junior high school teachers. Based on the validity test it was concluded that the e-module meets the valid criteria. The implication of this research is the development of e-modules needs to be continued to test practicality and effectiveness.

Beliefs about Beliefs about the nature of mathematics can impact teachers' confidence in teaching math and their professional development. A study with 187 elementary school teachers in Banda Aceh showed that these beliefs have a significant direct effect on increasing beliefs about teaching math but only a minimal direct effect on improving teachers' professional character. Beliefs about teaching act as an indirect-only mediation variable between beliefs about the nature of mathematics and teacher characteristics, suggesting a high and significant indirect effect. Further research is needed to confirm these results

[English]: Understanding students' difficulties in solving mathematics problems is crucial for effective teaching. This study aims to determine the ability of prospective mathematics teachers to analyze students' work in solving PISA problems and identify the types of assistance recommended to overcome students' difficulties. Using a descriptive qualitative design within a case study framework, the research subjects consisted of two prospective mathematics teachers from a university in Aceh, who had good knowledge in answering PISA problems. Data was collected through written tests, interview, and documentation of analysis results for student answers. This study was conducted in two stages: (1) the subjects analyzed, assessed, and recommended assistance for students' work, and (2) the researcher evaluated the results of the analysis and the appropriateness of the assistance proposed by the subjects. The findings indicate that varying Pedagogical Content Knowledge (PCK) abilities of teachers can affect the accuracy of the analysis and the effectiveness of the recommended assistance. Subjects with high PCK can analyze students' work and suggest assistance appropriately. In contrast, subjects with low PCK only analyze and provide suggestions to overcome students' difficulties in general. This study emphasizes the importance of integrating content knowledge and pedagogy in preparing prospective teachers. [Bahasa]: Memahami kesulitan siswa dalam memecahkan masalah matematika sangat penting untuk pengajaran yang efektif.

Noticing is the teacher's ability to pay attention to critical moments during learning. The noticing ability of preservice mathematics teachers can be trained by watching video recordings of teaching practices. However, there are limited video clips that can be used as teaching materials to develop the noticing abilities of preservice mathematics teachers. Therefore, this study aims to identify the characteristic of preservice mathematics teachers ability to notice. Video clips consist of a series of significant moments to observe. This research used a survey of moments in video recordings of preservice mathematics teachers when noticing their students' thinking in the learning process. The data analysis was based on learning video clips, containing the complexity of noticing problems related to the preservice mathematics teachers ability. The results indicated that the identified video clips, recordings of classroom interactions, featured teacher activities such as asking, guiding, responding, and assisting students. However, the preservice teachers demonstrated a low ability to notice, particularly in the interpreting and shaping aspects. These video clips, specifically those that highlight these teacher activities, can be utilized as learning tools in teacher development programs to enhance preservice teachers' noticing skills, especially in interpreting and shaping aspects.

Ineffective learning during Covid-19 can be a major cause of learning loss. Through polytomous item response theory analysis, this study seeks to identify learning loss of fractions and investigate the reliability and validity of the DINA model diagnostic test. This study involved 177 Grade 8 students from six junior high schools in Banda Aceh, Indonesia, to obtain information about the validity and reliability of the diagnostic test and learning loss of fraction due to Covid-19. The research was conducted by designing diagnostic test, expert validation, and empirical testing. Multiple choice problems with polytomous options were developed. This study produced 20 valid problems based on the level of item discriminant, item difficulty, and slip and guess, with a reliability of 0.899. This study revealed that learning loss was experienced by 62 students from low-level junior high schools (100%), 51 students from middle-level junior high schools (98%), and 54 students from high-level junior high schools (85.7%). It can be said that low-level schools have the highest percentage of students with learning loss. It is recommended that future studies evaluate the effectiveness of diagnostic tests in identifying learning weaknesses in mathematics before semester exams using the items generated in this study.

Mathematic has characteristics of abstract objects, so mathematical understanding is needed in studying mathematics. Until now, no research has examined students mathematical understanding viewed from multiple intelligences. This study aims to determine the profile of students mathematical understanding through diagnostic tests reviewed from multiple intelligences. This was a quantitative approach with population of all students in one of the junior high schools in Banda Aceh, Indonesia, and sample was 44 students selected by purposive sampling. Data collection was carried using multiple intelligence questionnaire and mathematical understanding test. Data analyzed using descriptive statistics. The results showed that students with mathematical logic intelligence able to define concepts verbally, interpret, identify, and distinguish concepts; students with linguistic, naturalistic, and existential intelligence able to define concepts verbally, interpret, and distinguish concepts; students with musical and kinesthetic intelligence able to define concepts verbally and interpret concepts; students with spatial intelligence able to interpret, identify, and distinguish concepts; and students with interpersonal intelligence able to interpret and distinguish concepts. The implication of this research is that teachers need to understand and realize that students' multiple intelligences are an important aspect that needs to be considered in delivering class material to improve students' mathematical understanding.

Mathematical representation ability (MRA) is crucial in solving mathematical problems, particularly in the topic of algebraic expressions. However, some students struggle to grasp algebraic forms in real-world circumstances. Learning through realistic mathematics education (RME) using context is one of the learning approaches that could help improve students' MRA. The objective of this study was to assess students' MRA in learningalgebraic expressionsthrough realistic mathematics education. This research employed mixed-method research with a sequential explanatory design. The subjects of this study were 27 seventh-grade students from a junior high school in Banda Aceh, Indonesia. Data on students' MRA were gathered through written test and task-based interviews. The descriptive analysis of written test data revealed that students' average score is 3.6, which is considered low compared to the maximum score of 8. The majority of students (n=24) satisfied the visual indicators of MRA as they successfully drew the composite shape. Whereas the most challenging MRA aspect for students to master was symbolic representation, only a few students (n=6) could solve the problem related to the multiplication of algebraic expressions. Students learning loss in the prerequisites due to online learning during the Covid-19 outbreak was one cause of the students' low performance on MRA.
