Abstract

Mathematics learning is often perceived as difficult by students due to the abundance of formulas and abstract concepts. This affects students' motivation and often results in poor understanding. Even before the lesson begins, students may assume that the material is too difficult, leading them not to try at all. This study aims to develop an interactive digital comic-based learning media using the Landbot.io platform. With engaging visual and interactive elements, the media is expected to increase students’ learning motivation and significantly improve their understanding. Landbot.io was selected due to its cost-free nature and user-friendly interface, making it accessible even to individuals without any previous experience in chatbots, catering to both developers and users. This study employs a Research and Development (R&D) approach, involving six 7th-grade students: two classified as having low abilities, two as having moderate abilities, and two as having high abilities. This aims to determine whether the media is effective for all cognitive levels. Data were collected through pretests and posttests to assess the effectiveness of the media. The results showed an improvement in students’ mathematics learning outcomes after using the media. Therefore, the media is considered effective in supporting conceptual understanding through visual and interactive approaches. Although there is still room for improvement, the media is generally suitable for classroom use.

Abstract

This research investigates the relationship between teachers' Technological Pedagogical Content Knowledge (TPACK) and class XI students’ learning outcomes, with a focus on factors that influence the effective integration of technology in teaching. Using a case study method with a qualitative and quantitative approach, this research involved five mathematics teachers and 100 students at SMAN 3 Sidoarjo. Data was collected through TPACK questionnaires, classroom observations, in-depth interviews, and student academic performance records. Analysis shows that higher levels of TPACK in teachers are positively correlated with improved student learning outcomes. Teachers with strong TPACK use technology effectively in their teaching, increasing student engagement and understanding. In addition, this research emphasizes the importance of collaboration with colleagues. Teachers who receive adequate training, resources, and technical support as well as collaborative support from colleagues are more successful in integrating technology into their teaching practices. These findings suggest that investing in ongoing professional development, providing strong administrative support, and creating a collaborative teaching environment are critical to improving student learning outcomes through technology.

Abstract

Mathematical reasoning can be influential in understanding learning materials. However, students’ mathematical reasoning skills are in the low category, especially in geometric transformation materials. This is due to the lack of learning media used by teachers. Therefore, this study aims to determine the process and result of developing mobile learning that is valid, practical, and effective. This research method is Research and Development (R&D) with the ADDIE development model consisting of Analysis, Design, Development, Implementation, and Evaluation. The research began with observations and interviews followed by making a design in the form of storyboard. Mobile learning was constructed using Articulate Storyline 3 application integrated with TeacherMade App, GeoGebra, and Wordwall then implemented in learning. Evaluation was conducted at each stage to make improvements to the mobile learning. The participants of study involved 21 students of class VIII-C SMP Laboratorium UM as well as lecturers and teachers as validators. The instruments used were validation sheet, mathematical reasoning rubric, response questionnaire, and test questions. The result showed that mobile learning developed was valid with an average validity score for media of 3.53, material 3.35, technology of 3.66, and language of 3.25. Practicality test result based on student response questionnaires obtained an average score of 3.2 which indicates that mobile learning is practical, useful, and effective. The test results showed that 80.95% of students achieved more than KKTP based on mathematical reasoning with an average score of 80.24 so that mobile learning met the effectiveness criteria.

Abstract

This purpose of this study is to describe students' written and oral mathematics communication abilities in solving probability problems based on their learning styles. This research uses a qualitative approach with qualitative description research methods. The subjects of this study were three ninth grade junior high school students with different learning styles (visual, auditory, and kinesthetic), equivalent mathematical ability, and the same gender. Data were collected from learning style questionnaires, mathematics ability tests, mathematical communication ability tests (both written and oral), and interviews. The mathematical communication ability test was analyzed using the mathematical communication ability indicators from Nurhasanah et al. (2019). The results of the study showed that in written mathematical communication, students with visual, auditory, and kinesthetic learning styles met four indicators: expressing a problem in mathematical ideas, expressing a problem in mathematical models, solving problems in an organized and structured way, and evaluating mathematical ideas. The difference is that visual students do not write what is asked but explain it through interviews, auditory students do not make a problem-solving plan, and there are inaccuracies in problem-solving among visual and kinesthetic students. In oral mathematical communication, students with visual, auditory, and kinesthetic learning styles met four indicators: expressing a problem in mathematical ideas, expressing a problem in mathematical models, solving problems in an organized and structured way, and evaluating mathematical ideas. The difference is that auditory students do not explain the information that is asked directly but rather through interviews. The benefits of this study can be used as a basis for designing teaching strategies that can improve students' mathematical communication abilities and to further develop future research.

Abstract

This study aims to describe the computational thinking processes of junior high school students with field independent (FI) and field dependent (FD) cognitive styles in solving numeracy problems in geometry and measurement content. This study uses a qualitative approach with descriptive analysis techniques. The research subjects were two students (one FI and one FD) of the same gender and with equivalent high mathematical abilities. Data were collected through the Group Embedded Figures Test (GEFT), AKM numeracy problems on geometry and measurement content, and interview guidelines. The results of the study indicate that FI students meet all five indicators of computational thinking, namely decomposition, pattern recognition, abstraction, algorithms and procedures, and generalization. Meanwhile, FD students only met three indicators: decomposition, abstraction, and generalization. These findings indicate that cognitive style influences the development of computational thinking skills, so teachers need to design appropriate learning strategies to support students with different cognitive styles in numeracy learning.

Abstract

This study analyzed the creative thinking ability of junior high school students in solving mathematics problems with the help of Artificial Intelligence (AI). The research employed a qualitative case study approach with three ninth-grade students of varying mathematical abilities (high, medium, and low). Data were collected through tests, observations, and interviews, then analyzed based on creative thinking indicators: fluency, flexibility, originality, and elaboration. The results showed that students' creative thinking skills were in line with their level of mathematical ability, where students with high mathematical ability were able to solve problems using unique approaches and detailed steps. However, there were minor errors in the conclusions. Students with moderate math abilities can use two different strategies, but they are still affected by AI solutions. Students with low math abilities tend to rely on AI-generated answers without modification. This study concludes that students' creative thinking ability is influenced by their conceptual understanding and how they utilize AI. Teachers need to guide students to use AI as an exploration tool, not just a source of answers.

Abstract

Mathematics learning, which is still dominated by an abstract approach, causes low interest and understanding of mathematical concepts among students. Therefore, the ethnomathematics approach is considered capable of bridging between local culture and mathematics education in a more contextual and meaningful way. This study aims to explore the forms of ethnomathematics contained in Saudagar-style Kudus traditional clothes and review them based on aspects of mathematical literacy, namely content, context, and process. This research used a qualitative method with an ethnographic approach. Data were collected through direct observation, semi-structured interviews with cultural figures, and visual documentation of the elements of Kudus traditional clothing. The results showed that Kudus traditional clothes contain various mathematical concepts such as flat and spatial shapes (rectangles, circles, cones, tubes), the concept of tangent lines, and arithmetic rows and series. The findings also represent aspects of mathematical literacy as a whole: content (space and shape, quantity, change and relationship), context (personal, occupational, societal, scientific), and process (formulate, employ, interpret, evaluate). Thus, Saudagar-style Kudus traditional clothes have great potential to be used as a contextual learning resource to improve students' mathematical literacy skills.

Abstract

This study aims to describe the influence of cognitive style on junior high school students' mathematical numeracy. The study used a quantitative approach with the ex post facto method. The subjects of the study were junior high school students classified based on Field Independent (FI) and Field Dependent (FD) cognitive styles. The instruments used included mathematical numeracy tests and the Group Embedded Figures Test (GEFT) to measure cognitive style. The population of this study was grade VIII students of SMP Negeri 2 Plandaan Jombang. Sampling was carried out using the purposive random sampling method so that 45 students from grade VIII C and VIII D were obtained as samples, where there were 21 FI students and 24 FD students. The results of the regression analysis showed that cognitive style had a significant effect on numeracy ability, with a coefficient of determination (R²) of 0.913. This shows that 91.3% of the variation in students' numeracy ability can be influenced by cognitive style. These findings indicate that students with Field Independent cognitive style have higher numeracy scores compared to Field Dependent students.

Abstract

Mathematics learning videos are audio visual media that make lessons more engaging by aligning with students’ audio-visual learning styles and illustrating real-life applications through digital storytelling. However, numeracy performance remains low—only 19% (4 of 21 students) mastered topics like mean, median, mode, and range. Efforts to address this problem are to use mathematics learning videos based on digital storytelling to strengthen students’ numeracy. This study aims to describe the content validity making such a video for strengthening students’ numeracy skills. In this research used the ADDIE development model, which focuses on three stages: Analyze, Design, and Develop with evaluations at each stage. However, this article focuses on the validation assessment of mathematics learning videos based on digital storytelling. The instruments used consist of a material expert validation instrument and a learning video validation instrument. The media was validated by three experts in the field of learning media, visual programming, and digital storytelling. The data analysis technique uses the Aiken V formula. Based on this, the results of the validation analysis are shown by obtaining a score of 0.854 from video experts (highest in usefulness) and 0.83 from material experts (highest in learning objectives) both were categorized as valid. The assessment by experts shows that the mathematics learning video is suitable for use with revisions. Several revisions were made to mathematics learning video based on digital storytelling to make it more interesting. Further research is recommended to develop the mathematics learning video into an application that can be used offline and allows for automatic answer storage settings.
