Abstract

Algebraic thinking ability are important for students to master and use algebraic concepts in various situations. Students with good algebraic thinking ability will find it easier to solve real-world problems and understand more abstract mathematical concepts. This study aims to describe students' algebraic thinking ability on linear equation material. Thus, the type of research used is phenomenology with a qualitative descriptive approach. The participants in this study consisted of 37 students; six students with heterogeneous abilities (high, medium, low) were then selected. The research subjects were determined by purposive sampling based on the pattern of answers representing the phenomenon that occurred. Data were collected using algebraic thinking ability tests and interviews to fulfill the validity of the data. The results showed that: 1) students with high algebraic thinking ability can use all indicators of algebraic thinking well. 2) students with medium algebraic thinking ability have difficulty in the indicators of analytical thinking, modeling, and dynamic thinking. 3) students with low algebraic thinking ability have difficulty in all indicators of algebraic thinking, namely generalization, modeling, abstraction, analytical thinking, dynamic thinking, and organization. So, teacher efforts are needed to provide students with an understanding of algebraic thinking so that students can solve math problems well.

Abstract

Indonesia’s dairy industry has undergone substantial development over the past decade, yet it continues to face persistent challenges arising from market liberalization and intensifying global competition. The BUSEP ratio policy, introduced in 1982, was designed to protect smallholder dairy farmers by mandating the absorption of domestically produced fresh milk by processing industries. This study aims to systematically examine the impacts of this policy on the welfare of key stakeholders: government, producers, and consumers, while also identifying the resulting economic and social implications. The research employs a systematic literature review combined with static comparative analysis using secondary data. Comparisons are drawn between conditions before and after the abolition of the BUSEP ratio policy, with specific attention to changes in producer surplus and consumer surplus. In addition, the study assesses the influence of a 5% import tariff on domestic milk pricing structures and supply conditions. The findings reveal that while the BUSEP ratio policy increased producer surplus, it significantly reduced consumer surplus, ultimately leading to a decline in net social welfare. The policy’s revocation in 1998 did not yield the anticipated benefits, as import prices surged sharply during the monetary crisis, preventing processors from optimizing alternative supply sources. Heightened competition with international producers further underscores the need for domestic farmers to enhance efficiency and competitiveness. Overall, the study indicates that existing policies have not optimally improved welfare outcomes. Consequently, there is a pressing need for more adaptive policy frameworks that prioritize production efficiency, price stability, and sustained protection for Indonesia’s dairy farmers.

Abstract

Statistical thinking is an essential competency for prospective mathematics teachers in responding to data-driven decision making within the context of Society 5.0. However, learning obstacles frequently emerge in higher education statistics courses due to instructional practices that emphasize procedural computation rather than conceptual and contextual understanding. This study aims to describe the implementation of a didactical design to reduce students’ learning obstacles in statistical thinking through the topic of measures of central tendency. A qualitative descriptive method was employed involving 38 mathematics education students enrolled in an introductory statistics course. The didactical design integrated the Theory of Didactical Situations (TDS) and the DORA model (Describe, Organize, Represent, Analyze–Interpret) and was delivered through an interactive e-module developed on the AnyFlip platform. Data were collected using a post-implementation statistical thinking test based on DORA, classroom observations, semi-structured interviews, and reflective field notes. Learning activities were organized into four TDS stages action, formulation, validation, and institutionalization to support reflective and adidactical learning processes. The results indicate that students were able to construct statistical concepts more meaningfully and reduce previously identified learning obstacles, particularly in linking numerical results with graphical representations. In conclusion, the integration of TDS and the DORA model supported by interactive e-modules effectively enhances students’ statistical thinking skills, as evidenced by the reduction of learning obstacles among prospective mathematics teachers.

Abstract

The professional competence of Madrasah Ibtidaiyah (MI) teachers in teaching ratio material is a vital factor in improving students’ understanding of mathematics, making it important to examine MI teachers’ knowledge of mathematics content. This study aims to analyze teachers’ professional skills, including their understanding of the concept of ratios, their attitudes toward preparing the learning process, such as creating teaching materials aligned with the curriculum, and their understanding of students’ characteristics and how they design learning. The results of this study provide an initial foundation for further research, which can help teachers develop learning methods through didactic studies. The subjects of this research are MI grade VI teachers in Bandung Regency, from six schools. The method used is a descriptive approach with a prospective analysis stage based on Didactical Design Research (DDR). Data collection involved teacher reflection sheets, exploratory interviews, observations, and document reviews. The findings indicate that teachers’ professional competence in knowledge of learning content and teaching methods remains at level 2, while their understanding of students’ characteristics and learning styles is at level 3. Reflection sheets and interviews reveal that teachers face difficulties beginning with defining ratios, particularly in understanding that the ratio of a to b differs from the ratio of b to a, and in solving problems involving equal proportions. Often, teachers plan their lessons with a simple sequence of materials in a journal, without considering the epistemic and systemic aspects of the content or validating their presentation and practice questions found in textbooks. MI teachers also find it challenging to select concrete teaching methods for ratios before moving to an abstract understanding, especially given the limited time. Based on these findings, there is a clear need for programs to improve teachers’ competence through didactic studies, equipping them to anticipate and address potential obstacles and enabling them to design compelling learning experiences. Since teachers’ professional competence in teaching ratios directly impacts students’ understanding of math, exploring their content knowledge is essential. This study contributes to empowering teachers through didactic design research, a necessary approach to enhancing teacher competence.

Abstract

AbstractThe research aimed to conduct an in-depth investigation of the learning obstacles faced by elementary students in the concept of fractions. Employing a qualitative method, this study involved the fourth and fifth graders of elementary schools as the participants. The data were collected both quantitatively and qualitatively. The quantitative data were collected through a test on the concept of fractions developed by the research team. Meanwhile, the qualitative data were collected via interviews. The data were then analyzed using quantitative and qualitative methods. The results of the quantitative data analysis indicated that the average number of students who answered the overall test questions correctly was 13.33%. Through qualitative analysis, it was found that the students experienced three types of learning obstacles including epistemological, didactical, and ontogenical obstacles. Epistemological obstacles were faced by the students in the construction of fractions as parts of a whole in the visualization of the model area. Didactical obstacles occurred in the construction of fractions as parts of a whole in the visualization of discrete models and improper fractions. Ontogenical obstacles occurred in the construct of fractions as measures, especially placing fractions on the number line. The findings of this study can be used as a basis for educators to develop learning designs on the concept of fractions in elementary schools.Keywords: concept of fractions, learning obstacles, elementary school students. AbstrakPenelitian ini bertujuan untuk melakukan investigasi mendalam tentang hambatan belajar yang dialami siswa sekolah dasar pada konsep pecahan.

Abstract

This study investigates how GeoGebra Classroom supports students in overcoming epistemological obstacles and enhancing mathematical literacy in learning exponents through Bruner’s representational approach. This qualitative phenomenological study involved 30 eighth-grade students from a junior high school in Gowa Regency, South Sulawesi, with 12 students purposively selected for learning sessions using GeoGebra Classroom. Three students representing low, medium, and high mathematical abilities were interviewed in depth. The research instruments included observation sheets, interview guides, and documentation of student learning activities. Data were collected through participatory observation, semi-structured interviews, and document analysis, and were analyzed using thematic analysis techniques. The study explored students’ learning processes through enactive, iconic, and symbolic stages. The findings indicate that GeoGebra Classroom facilitates gradual and exploratory learning through concrete manipulation and visual representations, enabling students to develop a deeper understanding of exponent concepts. However, some students experienced difficulties when transitioning to symbolic representations. This study contributes to digital mathematics education by proposing an instructional model that integrates technological tools with representational learning theory to enhance conceptual understanding and strengthen students’ mathematical literacy.

Abstract

Somatotype is a parameter used to determine criteria based on body type. However, not many have taken somatotype measurements when selecting prospective athletes. The purpose of this study is to examine the somatotype of fighters in Tarung Derajat Martial Arts. In this study, tests and measurements of somatotype were carried out using manual anthropometric measurements, including height, weight, skinfold measurements at five points (biceps, triceps, suprailliaca, subscapula, and calf), arm circumference, calf circumference, and measurement of the width of the humerus bone and femur. The purposive sampling technique is used in determining the sample. In this study, 15 Tarung Derajat martial arts athletes, consisting of seven men and eight women, were sampled. The results of this study showed that 7 athletes had a mesomorph endomorph somatotype with a percentage of 46%, 1 athlete had an endomorph somatotype with a 7% percentage, 6 central athletes had a percentage of 40%, and 1 athlete had an ectomorph endomorph somatotype with a percentage of 7%. Finally, the dominant body type in Tarung Derajat Fighter athletes is mesomorph endomorph (46%), followed by central (40%). This study's data provide physical characteristics of degree fighters, which can be used to establish a reference for systematic sports medicine research.

Abstract

The Yo-Yo Intermittent Recovery Test is frequently used to evaluate VO2max and is crucial for determining an athlete's physical condition. However, its effectiveness in accurately assessing the physical condition of football players remains limited. This study aims to analyze the level of the physical condition of football players' VO2max which will be used as evaluation material for designing training programs so that the pattern of coaching becomes focused and produces achievements. This research used a quantitative approach to the survey method. The subjects of this study were Pusaka FC football club athletes, the sampling technique used total sampling so that all athletes were a sample of 23 players. The test instrument used the Yo-Yo Intermitten Recovery Test level 2. Data analysis used descriptive percentages, with the assistanceof the Microsoft Excel 2019 software application. The results of the study show that the VO2max level value in soccer athletes is 13.04% of athletes in the poor category and 34.78% in the good category. Below average, 47.82% shows the average category, and there is only 4.35%, which shows the value of the good category. Based on the results of the VO2max ability test, the average classification of Club Pusaka FC players is still relatively low. However, it is necessary to know that the limitations of this study lie in the condition of the players' nutritional intake which has not been controlled and their age which must also be taken into consideration by researchers. Furthermore, it can find information on the effect of athlete nutrition on endurance ability.
