Abstract

Learning outcomes and self-efficacy are important learning factors. Mathematics learning outcomes can reflect the extent to which students have developed as learners, while self-efficacy reflects students' self-confidence in their own abilities in solving mathematical problems. This study was based on a qualitative approach, best practice. This best practice uses the STAR flow (“Situasi, Tantangan, Aksi, Refleksi”). The situation at SMAN 1 Mande, especially class XI, shows low learning outcomes and lack of self-efficacy. The challenge faced is planning and implementing differentiated learning to improve learning outcomes and student self-efficacy. Through a STEM-based differentiated learning approach, researchers designed and implemented contextual learning on the theme of global warming with integrating science, technology, engineering and mathematics. The results of this best practice indicate an increase in learning outcomes and student self-efficacy. STEM-based differentiated learning can also improve understanding of mathematical concepts at the high school level. Researcher recommend that educators embrace differentiated learning strategies by customizing their approaches to accommodate the diverse needs such as students' level of readiness, interests, and student’s learning profile. The significance of comprehending student characteristics, such as learning styles and thinking abilities is paramount, especially in the implementation of student-centered learning. Additionally, educators are advised to prioritize aligning learning objectives with the curriculum, ensuring relevance and engagement. This various approach aims to create a dynamic learning environment to resonates with students individualized level. Develop interventions to address students' lack of confidence in solving mathematical problems can improve self efficacy.

Abstract

Mathematics subjects at various levels of education are still considered difficult. One of the mathematical skills that students still lack mastery of is mathematical communication. Otherwise in mathematics learning, as explained in NCTM, "communication is a fundamental element of mathematics learning," which means that communication is a basic element in mathematics learning. Mathematical story problems are a form of problem in mathematical communication competence. Moreover, based on the PISA report, with low language skills, students' ability to solve story problems also becomes much more difficult. This purpose study are to indentify and analyze the difficulties of junior high school students in solving math story problems and alternatives to overcome them, and also demography analyze these difficulties based on gender, age and elementary school educational background. Utilizing an Exploratory Data Analysis (EDA) approach, data were collected from 291 students in grades 7, 8, and 9. The findings indicate that most students struggle with understanding the text of word problems, identifying relevant information, and modelling mathematical problems. Further analysis reveals that 9th-grade students, particularly those older, encounter more complex challenges but demonstrate better problem-solving abilities. Gender differences were observed in learning strategies, with female students tending to use more structured strategies such as note-taking or diagramming.

Abstract

This research explores the concept of ethnomathematics in the ayunan jantra culture in Majalangu Village, Denpasar, Bali. Using an ethnographic approach, this research identifies the mathematical elements contained in the making, structure and use of the jantJra swing. The research was conducted through observation, interviews and documentation when the ayunan jantra was used at a Balinese traditional ceremony. The interview was conducted with Mr. I Made Semara Putra, the manager of the Subak TeBA Majalangu Educational Tourism foundation, Denpasar, Bali. Swing jantra has a philosophy about the values of life, namely the rotation of destiny that we do not know, but must be ready to live it. The main findings of this research are the application of the concepts of geometry, proportion and oscillation in the making and operation of the ayunan jantra. From the geometry aspect, the swing structure includes the position of the support, rotating shaft, and arms that refer to the principles of symmetry and balance. In addition, the measurement of the dimensions of the arms and stand shows the application of the concepts of proportion and comparison. The use of the ayunan jantra also involves the concept of oscillation where the rotating movement resembles harmonic oscillation. This research reveals that Balinese people have intuitively integrated mathematical concepts into their cultural traditions. The findings from this study offer new insights into the relationship between cultural traditions and mathematics learning that could contribute to developing ethnomathematics-based learning in schools. This research is expected to enrich culture-based mathematics learning methods and preserve the local wisdom of the Balinese people.

Abstract

Student worksheets play a crucial role in mathematics education by providing a structured framework for exploring concepts, practicing exercises, and achieving learning goals. However, understanding slope, intercepts, and graphing in linear equations with two variables (LETV) remains a common challenge for many students. Therefore, this study aims to develop a student worksheet for linear equations with two variables to enhance students’ comprehension in that specific area of mathematics for junior high school students based on their difficulties in solving problems on linear equations with two variables and to identify such difficulties based on articles written by 20 scholars published in Sinta-accredited journals. This qualitative study used text data from 20 nationally Sinta-accredited peer-reviewed mathematics education journals that presented articles about the challenges or difficulties of this topic as experienced by students. The data were analyzed through an SLR method by identifying the patterns of students’ difficulties or challenges and by analyzing how the student worksheet will handle such problems as reported in journal articles. This study also reveals that students’ challenges in studying this topic of maths involve conceptual misunderstandings, procedural errors, graphical interpretation issues, lack of real-world application, lack of creativity, lack of ability in writing mathematical representations, difficulty in understanding word or story problems, lack of mathematical process skills, and recklessness.
