Abstract

This study aims to analyze the relationship between students’ interest in learning mathematics and their numeracy literacy skills in the context of the Merdeka Curriculum. The study employed a quantitative approach with a correlational design involving 60 eighth-grade students of SMP Negeri 27 Kerinci selected through simple random sampling. The research instruments consisted of a mathematics learning interest questionnaire using a Likert scale and a numeracy literacy test based on contextual PISA-model items. Data were analyzed using the Pearson correlation test after the assumptions of normality and linearity were met. The results showed a correlation coefficient of r = 0.56 with p 0.05, which falls into the moderate correlation category. These findings indicate that students’ interest in learning mathematics plays a significant role in supporting numeracy literacy skills; therefore, engaging and contextual learning strategies are needed to enhance both aspects.

Abstract

This study aims to determine the effect of the Green Education–based Contextual Teaching and Learning (CTL) model on students’ mathematical literacy skills. The study is motivated by the low level of mathematical literacy among eleventh-grade students at SMA Negeri 2 Kerinci in relating mathematical concepts to real-life problems, particularly those associated with environmental issues. The research employed a quasi-experimental method with a randomized control only design. The population of this study consisted of all eleventh-grade students at SMA Negeri 2 Kerinci. The sample included class XIB as the experimental group, which received instruction using the Green Education–based CTL model, and class XIA as the control group, which received conventional instruction. The research instrument was a mathematical literacy test. The results revealed that there was a significant effect of the Green Education–based CTL model on students’ mathematical literacy skills. This is evidenced by the hypothesis testing results, which showed a significance value of 0.027 0.05, indicating that H₀ was rejected and H₁ was accepted. Therefore, students taught using the Green Education–based CTL model demonstrated better mathematical literacy skills than those taught through conventional learning. The implications of this study suggest that the Green Education–based CTL model can be used as an effective alternative learning model to improve students’ mathematical literacy skills, particularly in advanced statistics material.

Abstract

Pneumonia is a disease which is having similar symptoms like ISPA. It is probably that making many parents did not realize if their children severe Pneumonia. Because according to Indonesia ministry health, there was significant increasingly Pneumonia cases year by year from 2021 to 2024, in 2024 is a year with highest Pneumonia cases, almost 800.000 Pneumonia cases even BPJS report, budget for Pneumonia therapy is highest than other diseases. Then, we need to make a quick preventative action, one of them is optimal control with rapid test. Rapid test is needed in order to detect an individual severe Pneumonia. In order, the aim will success so we need to develop SEIR model with add a control of rapid test to the exposed class. The addition is needed because children have symptom acquiring a certainty Pneumonia infected or not so the therapy will be quick and correct. After that, we need to find the optimal control of rapid test and then to describe the effect of optimal control on the exposed, infected, and recovered classes. The parameters values need to input to the equations which was given a control and next, we have to calculate with used sweep method step forward-backward and with helped by MATLAB software obtain the final result. The result is with control the number individual infected Pneumonia decreasing since initial time till 100th days, meanwhile without control the number individual infected increase till 10th days and after that the plot becomes decrease till 40th days.

Abstract

Mathematics learning in schools is still abstract and not yet relevant to students' lives. Mathematics learning should be linked to student activities such as scouting extracurricular activities. There are many scouting technical activities that can be used as contextualization in mathematics learning such as ceremonies, exploration, estimating, marching, pioneering, and semaphore. Thus, this study aims to identify mathematical concepts contained in scouting activities, especially in the construction of creative flagpole pioneering. This study is a qualitative study with an exploratory approach. Data collection methods used are observation, interviews, and documentation. The study was conducted on students who participate in scouting extracurricular activities at SMAN 2 Kendari, located on Jln. Sisingamangaraja, Rahandouna Village, Poasia District, Kendari City, Southeast Sulawesi Province. The results of the study show that in the pioneering flagpole creation building there are geometric concepts, namely rectangular, square, right triangle, acute triangle, obtuse triangle, right trapezoid, isosceles trapezoid, arbitrary trapezoid, right angle, acute angle, obtuse angle, overlapping lines and intersecting lines. and geometric transformations, namely rotation. These results provide recommendations to teachers to be able to use the pioneering building as an introduction to mathematical concepts.

Abstract

This research is conducted to design and developing digital teaching materials on the subject of opportunities for class XII SMA by utilizing the Flip PDF Professional application, as well as assessing as to examine their validity and practicality. The research applies a Design-Based Research (DBR) methodology using Plomp’s model, which includes three phases: initial research, expert evaluation with one-to-one sessions, and small-group plus field testing. Data were gathered using expert validation sheets and questionnaires for students. The results demonstrated that the developed digital instructional material obtained validity percentages of 95% from content experts, and 93.3% each from media and language experts. Student evaluations (one-to-one) yielded an average score of 93.9%, resulting in an overall average of 93.85%, categorized as highly valid. In the field testing phase, the teaching material achieved an average percentage of 83.51% in the indicators of ease of use, presentation, readability, and time efficiency, which falls into the "feasible" category. These findings indicate that the digital teaching material supported by Flip PDF Professional is suitable for use as an engaging, interactive, and student-centered alternative in mathematics learning.

Abstract

Errors in solving math story problems remain a common problem among students. This is due to the lack of in-depth analysis by teachers of the types of errors made by students based on Kastolan's theory, resulting in the same patterns of errors being repeated. Based on this problem, this study aims to identify and describe the types of errors made by students in solving mathematical story problems based on Kastolan's theory. This study uses a quantitative descriptive approach with a sample of 36 students in class X.E6 at SMAN 2 Bukittinggi, selected through purposive sampling. The research instrument was a story problem test on trigonometry consisting of five questions. The data were analyzed using descriptive statistics to obtain the percentage of each type of error. The results showed that 21 students (59.44%) made conceptual errors, 24 students (67.67%) made procedural errors, and 22 students (62.78%) made technical errors. Thus, procedural errors were the most dominant type of error made by students. These findings indicate the need for more systematic learning strategies and an emphasis on procedural understanding in solving mathematical story problems.
