The current study reveals that as many as 66.67% of students have not been able to achieve the minimum requirements, especially in the section of geometry; reflecting a need to improve mathematics learning outcomes. This gap in learning outcome is due to the fact that a majority of students tended to be passive during learning. The STAD learning model is a learning model that emphasizes student activities and interactions for learning mathematics in the classroom. The research design used in this study is a one group pretest posttest design. The sampling method used in the study was purposive sampling from a class of thirty elementary school students with issues related to mathematical abilities. Data collection techniques consist of primary sources in the form of tests, interviews, and observations, while secondary sources include documentation and literature studies. The data analysis technique used is the t-test (or using the Wilcoxon test if the data is not normally distributed), and the Gain Test. The results showed that there is a positive influence of STAD model on learning outcomes.</p>2023-03-30T00:00:00+07:00Copyright (c) 2023 Samsul Pahmi, Nanang Priatna, Karina Yulianti, Fitria Nurulaenihttps://jurnal.ustjogja.ac.id/index.php/union/article/view/14240The implementation of educational games to enhance elementary school students' interest in mathematics2023-05-02T08:35:28+07:00Yosafat Manindo Turnipyosafatmanindo7591@gmail.comRobert Soesantorobert.soesanto@uph.edu<p>The present study is motivated by the issue of low interest in mathematics among students in private elementary schools in Jakarta. Despite the abundant resources and infrastructure that support learning, technology has not been fully utilized to enhance students' engagement with mathematics. Consequently, students' learning interest has been declining, which in turn negatively impacts their enthusiasm and passion for learning. The aim of this study is to investigate how the application of educational games can increase the learning interest of elementary school students in mathematics, using a descriptive qualitative method. Educational games offer a convenient and effective means for teachers to deliver material, as they create an active, enthusiastic, and enjoyable learning environment in the classroom. The combination of technology and the role of the teacher is essential in supporting students' learning and developing human resources. By integrating educational games into the curriculum, students' interest and attraction in learning mathematics can be enhanced, making educational games an effective tool for increasing students' learning interest. Based on the findings of this study, the researcher suggests the importance of developing educational games and digital teaching materials, as well as moving away from conventional teaching methods. These recommendations are essential for enhancing students' learning interest and promoting effective learning in the classroom.</p>2023-03-30T00:00:00+07:00Copyright (c) 2023 Yosafat Turnip, Robert Soesantohttps://jurnal.ustjogja.ac.id/index.php/union/article/view/14270Differentiated learning and mathematical creative thinking2023-05-02T08:35:25+07:00Nindi Sri Rahayuppg.nindirahayu06@program.belajar.idMuhamad Sofian HadiM_Sofianhadi@yahoo.com<p class="UNION07AbstractEng"><span lang="IN">The purpose of this study was to analyze publications on differentiated learning and mathematical creative thinking in order to increase aligned referrals.

The results showed that 1) students with a visual learning style were able to do transductive reasoning, analogies, used relationship patterns to analyze situations, compiled conjectures and could estimate answers, and they were able to explain patterns; 2) students with auditorial learning styles were able to do transductive reasoning, analogies, used relationship patterns to analyze situations, compiled conjectures and could estimate answers; 3) students with a kinesthetic learning style were able to do transductive reasoning, analogies, could use relationship patterns to analyze situations and compiled conjectures, and they were able to make generalizations.</p>2023-03-30T00:00:00+07:00Copyright (c) 2023 Rahayu Tirta Kusumah, Aan Subhan Pamungkas, Jaenudin Jaenudinhttps://jurnal.ustjogja.ac.id/index.php/union/article/view/14048Mathematical representation ability: A systematic literature review2023-05-02T08:35:38+07:00Jasmine Salsabila Lutfijasmines.salsabila@upi.eduDadang Juandidadang.juandi@upi.edu<p class="UNION07AbstractEng"><span lang="IN">One of the psychological aspects of students that encourage students' mathematical representation ability is self-confidence. The mathematical representation ability of each student is not the same, because of the student's ability to receive and process the information that the teacher has given during the lesson. Thus, the cognitive style also affects the ability of mathematical representation. This article is a systematic literature review (SLR) of 25 studies published until November 2022 with the help of the Publish or Perish (PoP) application with the Google Scholar database. This article aims to investigate: (a) the characteristics of the period, index, research approach, subject matter, and demographics of the participants in the identified articles, (b) learning methods that can improve students' mathematical representation and self-confidence abilities, and (c) the most frequently used cognitive style type. The results of research with SLR show that the Problem-Based Learning (PBL) learning model is effective and able to develop students' mathematical representation skills, and student self-confidence. Mathematical representation ability studies based on cognitive style mostly use Field Dependent (FD) and Field Independent (FI) types, and rarely use spatial and visualizer-verbalizer types. The results of this SLR can be useful for other researchers who are interested in researching this topic in the form of research gaps that can be done for the next research.</span></p>2023-03-30T00:00:00+07:00Copyright (c) 2023 Jasmine Salsabila Lutfi, Dadang Juandihttps://jurnal.ustjogja.ac.id/index.php/union/article/view/13639The Influence of mathematics learning interest on the conceptual understanding of eighth-grade middle school students2023-05-02T08:35:54+07:00Hilma Adzki Hidayatihilmadzk@gmail.comDadang Rahman Munandardadang.rahman@fkip.unsika.ac.id<p>This study aims to determine the effect of interest in learning mathematics on the understanding of mathematical concepts in grade VIII junior high school students in the matter of number patterns. Number pattern material is one of the materials contained in the 2013 curriculum for class VIII which is expected to be mastered by students and students because it is closely related to everyday life. In this study the population was all class VIII students of SMP Negeri 28 Tangerang for the Academic Year 2022/2023. The sample selection was carried out in this study by means of probability random sampling, namely class VIII-D students as many as 36 students. The approach used in this research is quantitative and analyzed by simple linear regression. The technique of collecting data by providing non-test instruments in the form of questionnaires on students' interest in learning mathematics and test instruments on the subject of number patterns to measure understanding of mathematical concepts that are closely related to everyday life. Hypothesis testing is done by simple regression with prerequisite analysis, namely testing the normality of the data and the linearity of the data. The results showed that there is no significant effect of interest in learning on understanding mathematical concepts with the regression equation . So it can be concluded that interest in learning affects students' ability to understand mathematical concepts in an insignificant way.</p>2023-03-30T00:00:00+07:00Copyright (c) 2023 Hilma Adzki Hidayati, Dadang Rahman Munandarhttps://jurnal.ustjogja.ac.id/index.php/union/article/view/14451Analysis of Mathematical Literacy Ability of Grade XI Senior High School Students2023-05-02T08:35:16+07:00Ahmad Lutfiahmadlutfifauzi@upi.eduElah Nurlaelahelah_nurlaelah@upi.edu<p><span style="vertical-align: inherit;">Mathematical literacy skills are important in the 21st century.
