Abstract

This study aims to identify elementary school students' understanding of mathematical concepts based on Neil D. Fleming's learning style theory (VARK), which consists of four main categories: Visual, Auditory, Read/Write, and Kinesthetic. A descriptive qualitative approach was used in this research, with the subjects being sixth-grade students of SDN 14 Cakranegara. The research instruments included learning style questionnaires, mathematical concept comprehension tests, and interviews. Data analysis was conducted in three stages: data reduction, data presentation, and conclusion drawing. The results showed that the majority of students had a kinesthetic learning style, indicating a preference for learning through physical activities and hands-on practice. Students with a kinesthetic learning style demonstrated a better understanding of mathematical concepts when learning methods involved physical activities. Additionally, several students exhibited a combination of visual, auditory, and read/write learning styles, reflecting variations in how they understand and apply mathematical concepts. Based on these findings, the study recommends that teachers implement varied teaching methods tailored to students' learning styles to enhance their understanding of mathematical concepts.

Abstract

The problem of this study was the low creative thinking ability of fifth-grade students at SD Negeri 8 Metro Timur. This study was conducted to determine the influence of the Realistic Mathematics Education (RME) approach based on miniature house media on students’ mathematical creative thinking skills. The method used in this study was a quasi-experiment with a nonequivalent control group design. The population of this study was 58 students, and the sample, consisting of the same number of students, was determined using purposive sampling. The hypothesis test was conducted using a simple linear regression analysis, which resulted in an Fcalculated value of 164.361 with n = 29. At a significance level of α = 0.05, the Ftable value was 4.21. Since Fcalculated > Ftable (164.361 > 4.21), and the significance value was 0.000 < 0.05, it was concluded that there was a significant influence of the RME approach based on miniature house media on the mathematical creative thinking ability of fifth-grade students at SD Negeri 8 Metro Timur.

Abstract

This research develops mathematics questions based on Higher Order Thinking Skills (HOTS) specifically designed to enhance students' higher-order thinking abilities through the context of waste problems. The purpose of this research is to develop HOTS-based mathematics questions within the context of waste issues. This study employs the Research and Development method using the ADDIE model (Analyze, Design, Development, Implementation, Evaluation). The development stage involves nine validators, consisting of subject matter experts, question experts, and media experts. The implementation stage involves 38 students divided into two groups. Validity, reliability, distinguishing power, and difficulty level of the mathematics questions are tested by having students work on the developed HOTS questions. The assessment of the practicality of the mathematics questions based on HOTS is conducted through student response questionnaires. The validation results from the nine validators indicate criteria of "Very Worthy to Use." The content validity tests are considered valid and reliable, resulting in difficulty levels and distinction powers that meet the criteria. The practicality trial of the mathematics questions based on HOTS with the context of waste issues received "very strong" criteria among the students. Based on these results, it can be concluded that the HOTS-based mathematics questions with the context of the waste problem as many as 20 questions are valid, practical, and suitable for use, because they have met the five requirements or characteristics of good questions, namely validity, reliability, objectivity, practicability and economy.

Abstract

Abstract This study aims to examine the extent to which the Project-based Learning (PjBL) model impacts mathematics learning outcomes on the topic of length units for third-grade students at SDN 2 Bendanpete. The research employs a quantitative experimental method through a Pre-Experimental Design approach, specifically using a One-Group Pretest-Posttest Design. The data analysis techniques include prerequisite tests through normality testing and hypothesis testing using the Paired Sample T-Test. Data were collected through multiple-choice tests administered before (pretest) and after (posttest) the implementation of the Project-based Learning (PjBL) model. Instrument validation results indicated that 15 items were valid, and reliability testing showed a high reliability score with Cronbach’s α = 0.860. Data analysis through the t-test, resulting in a value of (-19.0), demonstrated a significant improvement in student learning outcomes, with the average posttest score (81.1) considerably higher than the average pretest score (51.4). These findings suggest that the application of the PjBL model effectively enhances student achievement in the topic of length measurement. It is expected that the outcomes of this research will provide new insights into the use of innovative instructional models to improve student learning achievement.

Abstract

The impact of boycotts against global brands has directly influenced the marketing approaches of fast-food companies such as KFC and McDonald’s. This study aims to identify the most effective marketing strategies that both companies can adopt in response to these challenges. The research utilizes a two-player game theory model with a mixed strategy approach, analyzed through matrix algebra—specifically involving calculations of cofactors, adjoints, and determinants. Data were collected via questionnaires distributed to 100 students at the University of Mataram, focusing on four key strategic variables: communication, promotion, innovation, and service. The response matrices were simplified using row and column dominance elimination before further analysis. The results show that KFC’s optimal strategy consists of a combination of 60% innovation and 40% promotion. In contrast, McDonald’s performs best with a balanced strategy, applying 50% promotion and 50% innovation. A game value of –12 indicates that McDonald’s holds a relative advantage in minimizing potential losses during the boycott period. This study contributes valuable insights into quantitative marketing strategy analysis using a mathematical framework.

Abstract

This study was conducted with the aim of describing the forms of conceptual errors made by Mathematics Education study program students in solving set and function problems in real numbers, and analyzing the causes of errors made. The research method used was qualitative with descriptive method. The research subjects consisted of five students who were randomly selected, with the condition that they had taken related courses but still showed errors in working on problems. Data were collected through a questionnaire test designed to reveal students' conceptual understanding and analyzed using Kastolan's error classification. The results showed that procedural error was the most dominant type of error, with a percentage of 60%. Conceptual errors and technical errors each had a percentage of 20%. This finding shows that students still have difficulty in following the steps of solving problems coherently, understanding basic concepts, and performing calculation operations carefully. Therefore, improvement is needed in learning strategies that emphasize concept understanding, procedural accuracy, and technical accuracy

Abstract

This study aims to analyze the effectiveness of the KOPSINU teaching aid in the Make a Match learning model for improving students' numeracy literacy. The research is based on the low numeracy literacy of Indonesian students, which is caused by less interactive learning methods and minimal use of teaching aids. A quantitative approach with a quasi-experimental posttest-only control group design was used. The subjects consisted of 60 seventh-grade students at SMP Islam Sultan Agung 4 Semarang, divided into experimental and control groups. The research instrument was a numeracy literacy test covering aspects of mathematization, symbolization, reasoning, and argumentation. The t-test results showed a significant difference between the two groups, with the experimental group scoring higher on the posttest. These findings indicate that the use of KOPSINU significantly enhances students' numeracy literacy by creating a more interactive, engaging, and motivating learning environment that helps students actively understand mathematical concepts.

Abstract

Mumps is a contagious viral disease transmitted through respiratory droplets and close contact. It can cause symptoms like fever and salivary gland swelling. Despite the MMR vaccine, which offers partial protection, outbreaks persist, especially in college-aged individuals. Epidemiological models can aid in identifying effective prevention strategies for controlling mumps transmission. This paper proposes a mathematical model for mumps spread, considering quarantined individuals and complications. A global stability analysis of the mumps transmission model was performed, considering mortality and quarantine subpopulation. The Disease Free Equilibrium and Endemic Equilibrium Point are globally stable, confirmed by Lyapunov functions. Sensitivity analysis of the basic reproduction number shows that reducing birth rates and contact between infected and susceptible individuals effectively minimizes the infected population. However, increasing the natural death rate can reduce the total population, which may lower infections, but poses potential social and economic challenges for decision-makers.
