<![CDATA[This research is based on the mathematics learning outcomes of elementary school students which are still low in terms of student learning outcomes. 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.]]>

<![CDATA[The study's goal was to see how the cooperative learning model STAD type aided by interactive learning media in terms of students' understanding of mathematical concepts in algebra material at SMP Negeri 1 Suwawa. With 25 students per class were determined using the experimental research post-test only control group design with two classes as a research sample and simple random sampling. As a result, students' ability to understand mathematical concepts in the STAD type cooperative class is higher than in the control class's direct learning model. This is demonstrated by the mean value of students' ability to understand mathematical concepts in the STAD type cooperative model class, which is 70.36 compared to 63.48 in the control class. The inferential analysis using the t test revealed that H0 was rejected because tcount = 1.916 > ttable = 1.68. To summarize, the ability of students' concepts in the STAD type cooperative model class assisted by articulate storyline media is greater than in the direct learning model class.]]>

<![CDATA[This study aims to describe and evaluate the effects of game-based mathematics learning. Systematic Literature Review (SLR) is used as a method in this research by collecting primary studies through checking the Google Scholar database, Education Resources Information Center (ERIC) from 2013 to 2022 with the keywords "games and learning mathematics" or "games and mathematics education", resulting in 25 relevant primary studies with inclusion criteria. The analysis technique used for the articles or primary studies that have been collected is that each primary study is recorded, then classified by title and year of study. Furthermore, each of the articles included in this study was analyzed to obtain the findings and discussion required to draw conclusions from this SLR study. It shows several results from the 25 articles used as material for the analysis of game-based mathematics learning, namely: 1) There are two types of games that are applied in the process of learning mathematics, namely traditional games, and modern games. 2) In general, the influence of the application of games, both traditional and modern, on learning mathematics is to improve the quality of learning with better indicators of teacher skills and student activity. From the results of this analysis, it can be concluded that the application of games in the process of learning mathematics is effective, because it affects the quality of learning mathematics in schools, especially by increasing student competence. The findings of this study also contribute to providing information related to the trend of game-based mathematics learning in Indonesia, which is expected to become recommendations and ideas for further research.]]>

<![CDATA[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.]]>

<![CDATA[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.]]>

<![CDATA[The purpose of this study was to analyze publications on differentiated learning and mathematical creative thinking in order to increase aligned referrals. Data collection techniques used PoP (Harzing) software, while data analysis utilized VOS Viewer software. A total of 200 articles on differentiated learning and mathematical creative thinking were retrieved from Google Scholar data sources from 2013 to 2023 and were analyzed using a bibliometric analysis approach. The bibliometric analysis included sources, authors, and accuracy derived from the keywords "differentiated learning and mathematical creative thinking," which were analyzed by the author and illustrated using the VOS Viewer software. Based on the study's results, it was found that there is a relationship between the term "differentiated" and the words "creative thinking, curriculum, teachers, and public junior high schools." Furthermore, the term "differentiated" is widely used in research on "differentiated learning," including differentiation and its relation to creative thinking. This research was widely conducted in 2018-2019. Additionally, many other researchers have carried out research on differentiation in differentiating learning. Future researchers can choose data sources other than Google Scholar in PoP (Harzing) software during data collection to enhance this research in increasing aligned references regarding differentiated learning and mathematical creative thinking.]]>
