Abstract

Understanding geometric concepts, particularly angles in circles, is fundamental in junior high school mathematics and is crucial in enhancing students' higher-order thinking skills. Assessing students’ cognitive understanding requires valid and reliable instruments that align with curriculum standards and student abilities. This study aims to construct and characterise a cognitive test instrument on angle material in circles through item analysis using Classical Test Theory with Microsoft Excel and Modern Test Theory with RStudio. A mixed-methods approach combining qualitative and quantitative techniques was used to collect data through observation and item analysis. The test instrument consists of five items to measure students’ understanding and analytical abilities. Content validation using the Aiken formula yielded an Aiken index of 1 for each item, indicating all items were valid. Classical analysis showed that items 1 and 3 were difficult, while items 2, 4, and 5 were of medium difficulty. Using the Partial Credit Model (PCM), all items fell within the medium-hard difficulty range. Power differential analysis revealed that item 3 was poorly constructed and should be removed. The results demonstrate that the developed instrument is valid and can differentiate levels of student understanding. This test is expected to support efforts to improve mathematics learning and better prepare students for numeracy literacy components in the Minimum Competency Assessment (MCA). The instrument also provides a framework for developing similar tools in other areas of mathematics education to enhance the accuracy of student learning evaluations.

Abstract

Numeracy literacy is the ability of students to understand, interpret, and apply mathematical concepts in various contexts of daily life. This study aims to analyze the numeracy literacy abilities of students with an introvert personality type, which has rarely been studied in previous studies. Most studies focus more on cognitive factors without considering personality, which influences students' performance in solving mathematics problems. This study involved 32 eighth-grade students of SMPN 6 Pasuruan who were classified as introverts based on Jung's Type Indicator (JTI). Data were collected through a numeracy literacy test of five questions with varying difficulty levels. The results showed that introvert students had an average score of 32.74 out of 100, with a tendency to excel in questions requiring in-depth analysis and accuracy. However, they have difficulty with tasks that require quick completion due to limitations in time management. If not addressed, this challenge can affect their academic achievement, especially in time-limited exams. Theoretically, this study enriches the understanding of numeracy literacy by considering personality factors. Practically, the results of this study can be the basis for designing more inclusive learning strategies, such as gradual training in time management. From a policy perspective, these findings provide recommendations for schools to develop more flexible assessments to support students with different learning characteristics.

Abstract

The combination of rainbow coloring and anti-magic labeling is known as Rainbow Antimagic Coloring (RAC). The Rainbow Antimagic Connection Number (RACN) of a graph G is the smallest number of colors induced by all edge weights under an antimagic labeling, symbolized as rac(G) A graph is said to have rainbow antimagic connectivity if for every pir of vetices x∈V(G), there exits a rainbow antimagic path, wherin all edge weights along the path are distinct. Let G be a graph with vertex set V(G) and edge set E(G). A bijective function f from V(G) to {1,2,…,|V(G)|} is applied, wherein the weight of the edge uv∈E(G) is defined as w(uv) under f which is obtained from w(xv)=f(x)+f(v). A rainbow path x-v is a path in a vertex-labeled graph G if for any two edges xv,x' v'∈E(P) the path satisfies w(xv)≠w(x'v'). If there is a rainbow x-v path P for every two vertices x,v∈V(G) then the function f is called a rainbow antimagic labeling of G. A graph G we say has an RAC, if we assign each edge xv with an edge weight color w(xv). In this paper, we present the RACN of the comb product of cycle C_3 with path P_n and broom Br_(n,m) symbolized by C_3⊳ P_n and C_3⊳Br_(n,m). A comb operation on a graph G, symbolized as G⊳H, is a graph product wherein each vertex of G is replaced by a copy of H, maintaining the structure of G. This operation helps construct new classes of graphs with specific connectivity and labeling properties.

Abstract

Critical thinking is an advanced thinking skill that requires students to think rationally and logically. This study aims to describe the critical thinking ability of students. The research was conducted in MAN 1 Malang in class XB, consisting of 32 students. The method used was descriptive qualitative research with three subjects representing high, medium, and low categories of critical thinking skills. The data collection techniques used were tests and interviews. The data analysis technique used was the analysis of test scores and interviews, with a credibility test for data validity. The results showed that high-category subjects were able to fulfill six critical thinking indicators (interpretation, analysis, evaluation, conclusion, explanation, and self-regulation) and could answer in two different ways. Medium-category subjects were able to fulfill the indicators of interpretation, analysis, conclusion, explanation, and self-regulation, although there were less precise answers. Subjects in the low-category did not meet the indicators of critical thinking skills and could only answer in one inappropriate way. Based on these results, teachers can provide open-ended or non-routine problem sets to improve students' critical thinking skills.

Abstract

Amid growing interest in integrating digital tools to enhance student engagement, this study aims to enhance fourth-grade elementary students' interest in learning mathematics by implementing Quizwhizzer as a learning medium. The research employs a Classroom Action Research (CAR) design, consisting of two cycles, each comprising two sessions. Each cycle follows the stages of planning, action implementation, and reflection. In the first cycle, questionnaire results indicated that 62.07% of students had low learning interest. However, 96.55% of students demonstrated high interest in the second cycle. These findings suggest a significant increase in students’ interest in learning mathematics following using Quizwhizzer. The study concludes that Quizwhizzer is an effective tool for fostering learning interest. Nonetheless, challenges related to time and classroom management were encountered, prompting a recommendation for better planning and management in future implementations.

Abstract

In addition to the theory and implementation, the description of research trends and the direction of development of mathematical mindset research still needs to be explored. The study aims to find trends and mapping from the mathematical mindset research development. The method used is bibliometric with the help of MS Excel and VosViewer. The metadata is 995 articles indexed by Google Scholar from 2019 to 2025, obtained from Publish or Perish by entering the keyword "mathematical mindset." The results show a sharp decline in post-2020 publications, the most in 2020, as many as 272, but plummeting to 3 in early 2025. This decline occurred due to policy changes after the pandemic, reallocating funding to digital learning, and competition for research priorities. Boaler's book related to Mathematical Mindset 2022 became the publication with the most citations (2329). The VOSviewer analysis results identified four main clusters, with the mathematical mindset being in cluster three. In addition, it found the potential for a weak connection with technological terms, which could be a new research direction. The results of this study provide optimism and opportunities for mathematical mindset research to be more associated with other terms that can be connected, especially in mathematics education research.

Abstract

Problem solving is the core goal in learning mathematics. However, TIMSS and PISA results show that Indonesian students' problem-solving abilities are still low. This study aims to describe the process of junior high school students in solving statistics problems using Polya's stages, supported by GeoGebra Classroom as an interactive visual learning tool. This descriptive qualitative research involved 31 grade VIII junior high school students as participants, who then selected three subjects through purposive sampling. Data were collected through tests, interviews, and field notes, then analyzed through data reduction, data presentation, and conclusion drawing. The results showed that highly category problem-solving subjects fulfilled Polya's stages. Medium category subjects completed most of Polya's stages, although some information was missing in the answer. Meanwhile, low category subjects could not solve the problem and did not fulfill Polya's stages. This study concluded that students who follow Polya's stages tend to perform better. Unlike prior research, this study shows how integrating GeoGebra Classroom can support student engagement in each stage of Polya's model. These findings emphasize integrating technology-based non-routine tasks to improve students' problem-solving ability.

Abstract

Population estimates are needed to project future populations, allowing for preparation in facing the possible impacts of population growth. This study aims to find a general formula or formula for the first-order linear differential equation and the arithmetic method based on the average value of the error of both, in projecting the population in Surakarta City in the future, and to determine the method that has a higher level of accuracy. This study is included in the category of descriptive research with a quantitative approach. Data were collected through literature studies and documentation of the population in Surakarta City from 2016 to 2024. Meanwhile, data analysis was carried out using quantitative descriptive analysis and comparative analysis. The study results show that the formula obtained for the first-order linear differential equation method is N(t)=562801 exp(0.0071997706t. While the formula obtained for the arithmetic method is Pt = 562801 (1+0.007357544t). From the comparison of the two methods, the arithmetic method is proven to be more accurate because it has a smaller average error (MAPE-based) than the first-order linear differential equation method.  These results can provide insight into the best methods for estimating population growth as the basis for population policy planning and regional development.

Abstract

Numerous primary studies have explored the impact of the Problem-Based Learning (PBL) model incorporating ethnomathematics on students’ mathematical abilities. However, variations in research findings have hindered the formation of a consistent conclusion. This study aimed to evaluate the overall effect of the PBL model based on ethnomathematics on students’ mathematical competencies through a systematic review and meta-analysis. Eleven relevant articles were selected via Google Scholar using the Publish or Perish tool and screened based on PRISMA guidelines, including identification, screening, eligibility, and inclusion phases. Data analysis was conducted using Comprehensive Meta-Analysis (CMA) software version 3.0. The calculated effect size, based on Hedges' g and employing a random-effects model, was 0.974, which is categorised as large. Further analysis examined two moderating variables: types of mathematical abilities and educational level. The results demonstrate that the PBL model grounded in ethnomathematics significantly enhances mathematical abilities, particularly in problem-solving and critical thinking skills. Additionally, the model is notably effective at the elementary and junior high school levels. These findings underscore the value of integrating local cultural contexts into mathematics instruction and support the development of innovative, culturally responsive learning strategies that align with modern educational goals.
