Mathematical communication skills are essential for prospective elementary school teachers. However, many problems still occur in prospective elementary school teachers related to their mathematical communication skills. This study aims to describe the mathematical communication skills of prospective elementary school teachers and their level of self-regulated learning. This qualitative research, employing a phenomenological design, aims to explore and identify the mathematical communication skills of prospective elementary school teachers. Forty-eight prospective elementary school teachers participated in this study, and nine were selected for in-depth interviews to understand their mathematical communication skills better. The results showed that prospective elementary school teachers with high self-regulated learning almost met all indicators, prospective teachers with moderate self-regulated learning met three indicators, and prospective teachers with low self-regulated learning met one indicator. All of them were unable to provide mathematical solutions with rational reasons. Several factors cause prospective elementary school teachers not to have good mathematical communication skills, such as 1) lack of knowledge of basic geometry concepts, 2) lack of motivation to learn independently, 3) inability to manage what to learn, and 4) inability to evaluate their mistakes. Based on the research results, not all prospective elementary school teachers possess practical communication skills.

The low computational thinking and mathematical reasoning skills of students in fractions material indicate the need for more interactive and meaningful learning innovations. This study aims to analyze the effect of Problem-Based Learning assisted by Fun Math Quest based on QR Code on computational thinking and mathematical reasoning skills of elementary school students. This study used a mixed method with an explanatory sequential design. The research subjects consisted of 60 fourth-grade elementary school students selected using a purposive sampling technique. The research instruments included computational thinking and mathematical reasoning skills tests, student response questionnaires, interviews, and observations. Quantitative data were analyzed using N-gain, Independent Sample t-test, and effect size (Cohen's d), while qualitative data were analyzed descriptively to explain the quantitative results. The results showed that the experimental class obtained an increase in computational thinking skills (N-gain = 0.56) and mathematical reasoning skills (N-gain = 0.53) with a moderate category, while the control class obtained N-gains of 0.31 and 0.37, respectively. The results of the Independent Sample t-test showed that the computational thinking and mathematical reasoning skills of students in the experimental class were significantly higher than those of the control class. Effect size analysis showed a very large effect on computational thinking skills (d = 2.14) and a large effect on mathematical reasoning skills (d = 1.26). Qualitative data showed that the use of QR Code-based Fun Math Quest increased student engagement, supported systematic problem solving, and helped develop computational thinking and mathematical reasoning skills. In addition, student responses to learning were in the good category with an average of 75%. The conclusion of the study showed that Problem-Based Learning assisted by QR Code-based Fun Math Quest had a positive effect on elementary school students' computational thinking and mathematical reasoning skills and supported the creation of active, collaborative, and meaningful learning.

This study examines the effect of a Game Based Learning (GBL) model assisted by Quizizz on mathematical problem-solving ability and mathematical understanding of fifth-grade elementary school students, and exploring their learning experiences. A sequential explanatory mixed methods design was used with 70 fifth-grade students and one teacher at SDN Soreang in the second semester of 2025/2026. Data were collected through tests, open-ended questionnaires, interviews, observations, and documentation. Quantitative data were analyzed using Shapiro-Wilk normality test, Mann-Whitney U test, and N-Gain; qualitative data through reduction, categorization, and thematic analysis. Mann-Whitney U results showed significant differences in both variables (Sig. = 0.000 < 0.05). The experimental group achieved N-Gain of 56.11% (moderate) for problem-solving and 56.55% for mathematical understanding, far exceeding the control group (21.81% and 29.64%). GBL with Quizizz more effectively supports procedural engagement than deep conceptual reasoning. Student responses averaged 74% (good category). GBL needs supplementing with conceptual guiding questions and reflective activities to fully optimize mathematical understanding.

Teaching mathematics should be communicated properly to students, so they can understand the whole concept, especially teaching in primary school. Nowadays, some teachers teaching mathematics just to make students memorize the concepts, not understand the whole concepts. This may cause when they were still become students to learn in university, they didn’t understand mathematics well enough. Therefore, the purpose of this study is to explain how well mathematical communication ability of prospective primary school teachers. To do so, we used qualitative descriptive approach using mathematical communication test to collect data from a group of prospective elementary school teachers. Data were analyzed by categorizing each indicator to identify factors that affect their mathematical communication ability. The results shows that mathematical communication ability of prospective primary school teachers is still in moderate category and tends to be in low category. An overview of each factor based on mathematical communication ability indicators will be shown in this research. These findings emphasize the need for improving prospective primary school teachers’ mathematical communication ability to make their preparation more thorough before carrying out teaching.

This research is motivated by the low conceptual understanding and critical thinking skills of third-grade elementary school students in Science and Social Studies (IPAS), specifically on the ecosystem material. This study aims to examine the effect of applying the Team Games Tournament (TGT) cooperative learning model assisted by Baamboozle media on these two skills. The research method used is Mixed Methods with an Explanatory Sequential design. The sample consisted of 60 students divided into an experimental class (30 students) and a control class (30 students). Data collection used written test instruments, observations, and interviews. The results of the quantitative analysis using the Mann-Whitney test showed a significant increase in the experimental class compared to the control class. The average N-Gain for conceptual understanding in the experimental class was 0.71 (high category), and the N-Gain for critical thinking was 0.62 (medium category). Regression tests proved a positive correlation, where critical thinking skills contributed a 39.1% influence on students' conceptual understanding. Qualitative data supported these findings, showing that the integration of gamification and group competition successfully created an effective peer tutoring ecosystem, reduced boredom, and stimulated students to discuss and argue logically. In conclusion, the Baamboozle-assisted TGT model is proven effective in comprehensively improving students' conceptual understanding and critical thinking. Keywords: Team Games Tournament, Baamboozle, Conceptual Understanding, Critical Thinking, Science and Social Studies
