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.

Literature reveals that there are numerous factors that affect students' academic achievement. These factors range from internal factors with varying degrees of influence. Determining the dominant factors is highly useful as part of the effort and the planning of potential actions regarding what can be done to improve students’ academic achievement. The present study employed a systematic literature review method to identify the dominant factors. Results show that there are four dominant factors that affect students’ academic achievement. They are academic motivation, emotional intelligence, teachers, and peers. This finding confirms the complex nature of the factors that affect students’ academic achievement, which involve internal and external factors. Without disregarding the other factors, these findings suggest that schools and parents should pay close attention to the dominant factors in order to improve students’ achievement.

This research aimed to formulate a model of mathematical learning difficulties for children with dyscalculia to help children with dyscalculia overcome mathematics problems at school. This research is important to carry out considering that dyscalculia is a serious problem experienced by many students throughout the world. The SDTA model was built by analogizing the STIR model to non-communicable diseases. In this study, of 1247 students who conducted a series of tests (screening tests), there were 121 students, or 9.7% were initially identified as having dyscalculia. Furthermore, observations were carried out and confirmation was carried out with parents and teachers so that 119 students tested positive for dyscalculia. The research results showed that after intervention through treatment by the teacher, dyscalculia students experienced a very drastic decrease, especially in the material on recognizing and ordering numbers. Likewise, the results of model simulations on multiplication operation material illustrated the decline in students with dyscalculia. Specifically for division operations, the treatment process took relatively longer. Therefore, the simulation results in the SDTA model reflected students who are identified as having dyscalculia, along with planned intervention/ treatment, students could pass through the mathematics learning phase successfully.

Creativity could be interpreted as a person's cognitive abilities in solving problems by bringing up new ideas. The problems of students’ math achievement lows is math presented as finished product, ready to use, abstract and taught mechanistic. This case can be lead to the creativity of the less developed students because students are not given the opportunity to think and use theirs ideas in solving mathematical problems. Problem Based Learning Model is a learning model that emphasizes the concept and information outlined from the academic discipline. The purpose of this study is to analyzed students’ creativity in solving mathematical problems through Problem Based Learning model (PBL) in class VIII-1 MTsN Model Banda Aceh. Data qained based on the students’ worksheet in groups. The data acquisition is categorized into 5 levels (highest level 4 and lowest level 0) which is analyzed descriptively. The results is three groups were at level 4 with very creative categories, one group is at level 3 with creative category and another group is at level 2 with deeply creative enough category. To the conclusion is PBL model could cultivate the students’ creativity in solving mathematical problems.

Indonesia is an archipelagic country lies on the Pacific Ring of Fire, resulting in the country being vulnerable to disaster. Teachers need to accustom students to manage natural disaster situation in a more logical approach. Therefore, it is necessary to develop mathematical problems in disaster contexts. This research is an early stage of developmental research. The purpose of this study was to analyze the needs of teachers and students of mathematical problems in disaster contexts. The participants in this study were a mathematics teacher and 53 Year 7 and 8 students at one of the public junior high school, located in a Tsunami affected area, in Banda Aceh. Data collection involved an open questionnaire, and data analysis was carried out descriptively. The results showed that the teacher often provided mathematical problems in learning but had never read mathematical problems in disaster contexts. Also, only three students had ever read such problems. The results also revealed that nearly half of the students (41.5%) liked to solve mathematical problems. Besides, both the teacher and 71.7% of the students agreed and were willing to participate in the learning process involving mathematical problems in disaster contexts. The results of the study also showed that the mathematical questions in disaster contexts were limited. Thus, it is necessary to develop mathematical problems in disaster contexts.

The development of technology in education greatly influences learning strategies. Thus, teachers must adapt and present interesting and technology-based learning, such as e-comics. Therefore, the teacher must see in advance the extent to which students will accept e-comics for use in learning mathematics. This research aimed to determine students' perceptions of the use of e-comics as a media in mathematics learning. This research implemented a quantitative approach with a survey method. The samples were 124 students of Junior High Schools (SMP / MTs) in Aceh. The research data were obtained from questionnaires filled by students which were collected through the TAM (Technology Acceptance Models) framework which was distributed online. The results showed that students used e-comic as a learning media influenced by their perceived benefits and attitudes towards the use of e-comic. The perceived benefits of students' attitudes have a significant role in their behavioral intention to use e-comic in learning mathematics. This research implies that e-comics has the potential to be used as a media in mathematics learning, especially on material that is considered difficult so that it can attract students' attention.

Mastery learning remains a critical challenge in education, often resulting in the need for remedial programs to support students in achieving competency. Despite their importance, existing remedial programs frequently fail to achieve their intended outcomes due to a lack of engaging and efficient instructional tools. To address this gap, this study introduces a novel e-learning-based remedial video designed to enhance student learning on the topic of functions. The research aimed to develop a remedial learning video that meets the criteria for validity, practicality, and effectiveness. The study employed a Research and Development (R&D) methodology following the Plomp model, which consists of three phases: preliminary research, prototyping, and assessment. The research was conducted in a high school in Banda Aceh, Indonesia, involving three distinct groups: nine students participated in the readability test, 60 students undertook the diagnostic test, and 18 students engaged in remedial learning activities. Data collection utilized validation sheets for the video, diagnostic and remedial tests, and student response questionnaires, with descriptive analysis applied to evaluate the findings. The results revealed that the e-learning-based remedial video demonstrated strong validity, with expert assessments yielding a score of 86.19% (very valid). Practicality was confirmed by positive student feedback, with a response rate of 92.62%. Effectiveness was also evident, as 95% of students achieved mastery learning following the remedial intervention, and the N-Gain score reflecting improvement in student performance was 0.72 (high). These outcomes underscore the effectiveness of e-learning-based remedial videos as an innovative and interactive solution to address students' lack of mastery learning. The findings contribute to educational practice by offering teachers and students an accessible and effective tool to enhance learning outcomes, with significant potential for broader application.
