Abstract

This research aims to explore the activities of fishermen on the coast of Sungai Buntu Beach, Karawang, that contain mathematical concepts, and to map them into the learning outcomes of phases A–C at the primary school level. A qualitative approach with an ethnographic design was used, through observation, interviews, and documentation. The data were then analysed with data reduction, presentation, and conclusion drawing, and their validity was tested through triangulation. The results show that fish trading activities contain number concepts; calculating the catch in a basket reflects algebra through variables and simple equations; the salting and weighing of fish emphasise measurement, proportionality, and capacity; the shapes of boats, nets, baskets, drying racks, and fish crates demonstrate the application of geometric concepts in 2D and 3D shapes; and seasonal catch patterns, trading transactions, and the salting of dried fish provide a context for data analysis and probability. These findings affirm that the cultural practices of fishermen in the North Karawang coastal area, particularly those in Sungai Buntu Beach can be used as an authentic source for contextual, relevant, and meaningful mathematics learning, and are also applicable to other coastal regions with similar cultural characteristics such as the North Coast of West Java, supporting the development of local culture-based teaching materials to enhance students' motivation, understanding, and learning outcomes.

Abstract

This study is qualitative descriptive research that aims to describe eighth-grade students’ numeracy skills in solving a PISA 2022 quantity content problem. This focus is important because PISA-type tasks require reasoning, quantitative interpretation, and decision-making skills that are essential for students’ mathematical literacy in real-life situations. Thirty-two eighth-grade students of a junior high school in Jambi, Indonesia, participated in this study. Data were collected through a written test adapted from the PISA 2022 released items and follow-up interviews with selected students. The results showed that most students demonstrated low numeracy performance, particularly in interpreting information, performing multi-step calculations, and drawing correct conclusions. Only a small number of students were able to meet the expected indicators of numeracy skills. These findings indicate that students have not yet fully met the cognitive demands of PISA quantity tasks. The results highlight the need for instruction that provides more opportunities for students to practice contextual quantitative reasoning. For classroom practice, teachers are encouraged to incorporate multi-step contextual tasks that gradually strengthen students’ interpretation, strategy selection, and reasoning abilities. The findings also serve as a basis for further research on developing PISA-type jumping tasks adapted to relevant local contexts to support students’ numeracy skills.

Abstract

This study aims to analyze the variations in students' obstacles and difficulties in mathematical literacy across different skill levels and learning styles. Through qualitative research with a phenomenological approach, the subject selected using purposive sampling. This research involved nine students of a junior high school in Bandung, Indonesia, each representing three learning styles (visual, auditory, and kinesthetic) and three levels of mathematical literacy (high, medium, and low). Data were analyzed using data reduction, data presentation, and conclusion drawing. The findings relveal that students' obstacles and difficulties in mathematical literacy varie based on their skill levels and learning styles. Students with moderate and low skills commonly experience difficulties in understanding context, processing information, creating mathematical models, and arguing and evaluating solutions. Differences in learning styles also determine the types of obstacles and difficulties that arise: visual students have difficulty in understanding verbal information, auditory students have difficulty in interpreting symbols and visual representations without verbal explanations, and kinesthetic students need concrete experiences to understand abstract concepts. These findings emphasize the importance of adjusting learning strategies so that all stages of mathematical literacy can develop optimally for all students with varie learning styles.

Abstract

The widespread use of smartphones to play games and the lack of use as a medium for learning mathematics is the reason for the need for the development of smartphone-based edutainment learning media. The purpose of this research is to design and develop interactive edutainment learning applications of mobile mathematics games to help junior high school students to learn line and angles material. This mobile game-based application incorporates graphic design, background music, and animation, and a major structural element in game development to attract students. This research belongs to the type of Research and Development (R&D) and the model used is the ADDIE model that is carried out in a systematic stage. The results of the study show that the developed game meets the valid aspects, where the level of expert approval of the design functionality has an average value of 4,49 out of 5, meanwhile, the assessment of the material has an average score of 4,17 out of 5 and the user states that the game meets the practical aspect with an average score of  3,75 out of 5. It is hoped that this game-based learning application called "CORNER" for mobile devices can act as an additional tool for improving students' conceptual understanding and interest to learn through the scientific approach used.

Abstract

Due to the Covid-19 pandemic, face-to-face instruction in the field of education has been replaced by online learning. As a result, to meet the learning goals, teachers must be innovative and creative while delivering online learning. Student Achievement with Edmodo is one alternate online learning choice. This analysis aims to explain the effects of the introduction of Edmodo-supported Student Achievement, as well as student reactions to this learning, and to provide a single learning method that is successful and can aid teaching and learning experiences for high school mathematics content during the Covid-19 pandemic. This study employs qualitative analysis approaches. The subjects of this research were five students from Tasikmalaya City's State Senior High School. Based on the outcomes of a few experiments, it was determined that the learning experience was enjoyable and aided students' comprehension of the Trigonometry content. Students are pleased with the learning experience provided, and they believe they have made improvements as a result of their participation in the learning. According to the effects of the impact size estimation, the implementation of the Student Achievement learning model is very accurate. Then, for general student assessment, Student Achievement learning with Edmodo is beneficial to introduce in the middle of the Covid-19 pandemic, so that it can be used as a substitute in online learning.

Abstract

Textbooks used in schools affect the quality of mathematics learning in the country. Indonesian Ministry of Education (Kemendikbud) already lauched students’ and teachers’ textbook that are distributed nationally on 2013; however improvements are needed to revise the textbooks since there are concerns such as the difficulty level of problems contained in the textbooks. The main objective of this study is to compare non-routine problems contained in mathematics textbooks used in Indonesia and Singapore. This is a qualitative research with content analysis design. Researchers compare Singaporean and Indonesian mathematics textbook since Singapore got higher rank in mathematics based on PISA result in 2018. The topic in this study is limited to Pythagorean Theorem. The result of the research shows that Indonesia and Singapore has consecutively 22,1% and 11,3% non-routine problem. Another finding of this study was Singaporean mathematics textbook focused more on developing students’ fluency of solving problems, meanwhile Indonesian mathematics textbook focused more on students’ reasoning ability. The results and findings in this paper are expected to provide input in developing future mathematics textbooks.

This research was qualitative research which was conducted in July as an evaluation of the first online learning from March until July. 90 students were chosen by purposive sampling and then given an online questionnaire. The results showed that there were some mathematical courses students took in the Even Semester 2019/2020. The platforms used by lecturers while teaching Mathematics were 39.6% WhatsApp Group, 22% Google Classroom, 13.2% Cisco Webex, and 25.2 % others. Platforms that were felt effective as online learning applications were 52.7% Cisco Webex, 26.4 % WhatsApp Group, 9.9% Zoom meeting, 5.5% Google Classroom, and 5.5% others. This is felt to be effective because it does not consume a lot of data packages, has a strong signal, and can be accessed at any time (WhatsApp Group and Google Classroom). In addition, this platform can be used for live conferencing / video calls using whiteboards which are deemed effective for teaching math material (Cisco Webex). However, several obstacles were found during the implementation of online learning, namely difficulties in obtaining sufficient internet data packages; limited network; difficult assignments and assessments; less effective teaching methods; and use of multiple applications.
