Abstract

Numeracy skills are essential for prospective mathematics teachers as they bridge mathematical concepts with real-life applications. However, many prospective mathematics teachers face challenges in applying these concepts to practical situations. This study aims to analyze the conceptual and procedural errors made by prospective mathematics teachers when solving numeracy problems within the context of "Save Our Water." A descriptive research design was employed, utilizing a numeracy test adapted from the Minimum Competency Assessment (MCA) and semi-structured interviews as research instruments. The study involved 30 prospective mathematics teachers from the University of Jambi, Indonesia. The findings revealed that conceptual errors primarily stemmed from reliance on rote memorization of formulas without a deeper conceptual understanding. Procedural errors were attributed to difficulties in unit conversion, incorrect formula application, and improper manipulation of formulas. To address these issues, the study recommends incorporating contextual approaches, problem-based learning, and project-based learning strategies that connect mathematical concepts to real-world contexts. Additionally, the use of visual aids, such as diagrams and 3D models, is suggested to enhance conceptual understanding and strengthen the connection between abstract concepts and practical applications. Future research should investigate the effectiveness of these instructional approaches in improving numeracy skills and enhancing the teaching readiness of prospective mathematics teachers.

Abstract

In initial observations, it was seen that students did not write down what they knew (interpretation), were not precise in making mathematical models (analysis), were less precise in using strategies to solve problems (evaluation), and had no conclusions (inference). After paying attention, students have different learning styles. However, the learning model used has not been able to improve mathematical critical thinking skills in terms of learning style. This research aims to find out how mathematical critical thinking skills are treated with the STEM-based STAD learning model in terms of learning styles. This type of research is quantitative research with research subjects namely class X students at MAN 1 Muaro Jambi. The research design used was a posttest only control design. The population was 115 students from 4 classes and the sample consisted of 3 classes, namely experimental class I (29 students), experimental class II (29 students), and control (28 students). The sampling technique was carried out using the cluster random sampling technique.

Abstract

This study aims to develop a landing page as part of the digitalization strategy of PT Kosa Group Indonesia, a culinary company consisting of three main divisions: Kosarasa, Kosa Team, and Risafood. The development followed the waterfall method through observation, literature review, system design, implementation, and testing. The Framer platform was selected as a low-code solution due to its efficiency in building responsive, maintainable interfaces without the need for complex programming. This initiative was driven by the limitations of previously used platforms such as LinkTree, which lacked the capability for visual customization and did not effectively unify multi-division information. Performance testing using Google PageSpeed Insights showed an increase from 44 to 54 on mobile and from 44 to 55 on desktop after visual and structural optimizations. Usability testing using the System Usability Scale (SUS) yielded an average score of 87.25, which is categorized as excellent. The results indicate that low-code-based landing page development offers an effective solution to support business digitalization in the culinary sector, while maintaining development efficiency, strong visual identity, and user-friendly experience.

Abstract

Understanding mathematical concepts is one of the essential and fundamental aspects of mathematics learning in schools, with the aim of enabling students to develop the ability to understand mathematical concepts, explain the relationships between concepts, and apply concepts or algorithms flexibly, accurately, efficiently, and appropriately in problem-solving. This study aims to analyze and understand the extent to which students comprehend mathematical concepts, as well as to evaluate the effectiveness of the information processing system at MAN 1 Muaro Jambi in supporting students’ understanding of mathematical concepts. This research is exploratory in nature and employs a descriptive qualitative approach. The research subjects consist of three tenth-grade students selected using purposive sampling. The instruments used in this study are a mathematical concept comprehension test on the topic of SPLTV and interviews. Data analysis was conducted by reducing data from written tests and interviews, and by using methodological and source triangulation. The results of the study show that the three subjects demonstrated different levels of conceptual understanding, which were based on the memory storage components involved in each subject. It is therefore concluded that students whose information processing reached the Long Term Memory stage demonstrated a better exploration of mathematical concept understanding compared to those whose processing only reached the Short Term Memory and Sensory Register stages.

Abstract

Purpose: This study aims to investigate the enhancement of students’ geometric thinking through the integration of Discovery–Contextual learning strategies with van Hiele’s levels of reasoning. In addition, it examines the contribution of logical–mathematical intelligence to mathematics learning outcomes by synthesizing findings from prior research. Method: The research employed a classroom action research design implemented in three iterative cycles involving 13 fifth-semester mathematics education students. Data were collected through geometry thinking tests, observation notes, and the van Hiele-based assessment tool, then analyzed descriptively to track cognitive development across cycles. Complementing this, a meta-analysis of 41 empirical studies was conducted using a random-effects model to evaluate the consistency of logical–mathematical intelligence on students’ mathematics achievement. Findings: The results indicate steady improvement in students’ geometric reasoning, particularly at the deduction and rigor levels, with mean performance rising from 78.4% in the first cycle to 92.8% in the third. Reflection across cycles also revealed stronger engagement, reflective thinking, and collaborative learning. The meta-analysis further confirmed that logical–mathematical intelligence consistently exerts a strong and stable influence on mathematical performance across different educational stages and contexts. Significance: Findings highlight the pedagogical value of combining Discovery–Contextual learning with van Hiele’s framework to cultivate higher-order geometric thinking. At the same time, the evidence underscores the necessity of integrating logical reasoning into curriculum design and instructional strategies. Together, these contributions provide both theoretical insights and practical guidance for advancing mathematics education, especially in preparing prospective teachers to meet diverse cognitive needs.

Abstract

Geometry thinking ability is the ability of students in terms of observing objects, building definitions based on the characteristics inherent in the object, recognizing the relationship between one object with other objects, and applying it in solving geometry problems. However, the ability to think geometry students are still low. This is because students are still dependent on lecturers in receiving information and learning that occurs in the classroom has not facilitated the ability to think geometry, especially geometry transformation. For this reason, a student activity sheet based on Discovery- Contextual Learning based on van hiele theory was developed which is effective in improving the geometry thinking ability of mathematics education students of STKIP Muhammadiyah Sungai Penuh. The subjects of this study were 5th semester students of mathematics education. The development model used is adapted from the Plomp model. There are three stages in this model, namely preliminary research, prototype phase, and assessment. This study focused on seeing the effectiveness of the product at the assessment stage. The assessment phase was carried out on a field test consisting of 13 students for 9 meetings. The syntax of this learning model includes: 1) Stimulation, 2) Constructivism, 3) Problem Statement, 4) Data Collection, 5) Learning Community, 6) Modeling, 7) Data Processing, 8) Verification, 9) Reflection, and 10) Authentic Assessment.
