Abstract

This research discusses the mathematical model of Covid-19 disease. The model formed consists of 6 components, namely Susceptible (S), Exposed (E), Asymptotically Infected (A), Quarantined (Q), Symptomatic Infected (S), and Recovered (R). This research aims to determine the local stability analysis of the model formed. Apart from that, the R0 value of the model is also looked for. The model stability analysis was carried out in disease-free and endemic settings by showing asymptotic stability. Based on the analysis results obtained. The primary reproduction number for disease-free and endemic simulations is greater than 1. The interpretation of the COVID-19 mathematical model from the stability analysis shows that COVID-19 will still exist for a specific time and will not disappear.

Abstract

Field observations reveal that students in the Electrical Engineering program at Universitas Negeri Padang (UNP) struggle to master the standard mathematical content required, impacting their ability to comprehend advanced course materials. The current applied mathematics curriculum does not sufficiently support students in independently discovering concepts essential for engineering competencies. This study aims to establish a standardized competency design for applied mathematics that aligns with the mathematical requirements of the electrical engineering curriculum, thereby simplifying the learning of advanced courses. Utilizing a qualitative descriptive approach, this research gathers insights from alums, students, and expert lecturers through interviews. The findings identify seven essential mathematical topics that form the foundation of cognitive knowledge. These fundamental skills are crucial in achieving competencies that significantly contributing to success in advanced courses within the UNP Electrical Engineering program. The seven core topics include calculus, geometric and trigonometric functions, mathematical modeling and logic, discrete mathematics, integrals and differential equations, complex variables, and linear algebra

Abstract

Mathematics communication ability is an essential component of mathematics that students should have. However, the mathematics communication ability of students, especially in Indonesia, still needs to improve. This study offers a new and different view of mathematics communication to improve it. This study aims to develop an assessment tool for students’ mathematics communication to identify the problems so teachers can focus on improving those areas. Not only the cognitive domain of the students, but this study also includes assessments of the affective and psychomotor domains as well. The reason is that cognitive, affective, and psychomotor aspects are interconnected in mathematics communication. The study of these three domains is called behavior. The assessment tools consist of the mathematics communication behavior analytical rubric and appropriate mathematics test problems. This study is developmental research with three phases: the development of the analytical rubric, the development of mathematics tests, and the application. The participants in this study are two mathematics education experts and 240 students in the 8th grade from seven schools, each located in a different city. The findings of this research show that the developed assessment tools can be used to assess students’ mathematics communication behavior.

Abstract

This study aimed to develop a valid, practical, and effective Problem-Based Learning (PBL) mathematics teaching module integrated with scientific inquiry to enhance mathematical literacy among Grade X vocational high school students in a Computer and Network Engineering program. The development followed the Plomp model, comprising preliminary research, prototyping, and assessment phases. Data were collected through expert validation, student and teacher response questionnaires, observations, and pre- and post-tests. The module was validated by experts with an average score of 3.607 (very valid), while the student worksheets scored 3.582 (very valid). Practicality was confirmed with a 88.33% score from teachers and 88.40% from students, both categorized as very practical. The module significantly improved students’ mathematical literacy, with an average post-test score of 82.66, reflecting gains in formulating, employing, and interpreting mathematical solutions within real-world vocational contexts. Findings indicate that the integration of scientific inquiry into PBL fosters deeper engagement and strengthens problem-solving skills.
