This study examined the effect of Project-based Learning (PjBL) assisted by Microsoft Mathematics on students’ mathematical representation ability. A quasi-experimental design with a posttest-only control group was employed in two tenth-grade classes at a senior high school in Kolaka Regency. The experimental group received PjBL with Microsoft Mathematics, while the control group was taught conventionally. Data were collected through a representation test, a questionnaire, and an observation sheet, and analyzed using both descriptive and inferential statistics. Results showed that the experimental group achieved a significantly higher mean score (81.17) than the control group (60.19), with a mean difference of 20.99 points (p < 0.05). The questionnaire findings revealed very positive student perceptions, indicating that Microsoft Mathematics was easy to use, helpful in understanding concepts, and improved problem-solving skills, while also fostering interest and independence. Observation confirmed that PjBL was implemented effectively: teachers provided clear guidance, students designed projects, collaborated, and presented outcomes through various representations using Microsoft Mathematics. These findings demonstrate that combining PjBL with technology strengthens students’ mathematical representation ability and enriches learning. The study implies that technology-supported project learning can serve as an effective model for promoting meaningful, engaging, and skill-oriented mathematics education in secondary schools.Penelitian ini mengkaji pengaruh Project-based Learning (PjBL) berbantuan Microsoft Mathematics terhadap kemampuan representasi matematis siswa.

This study explores the procedural skills of grade VIII students in solving Pythagorean Theorem problems, focusing on the diversity of problem-solving steps and error patterns that emerge. A descriptive qualitative method was used in this study, with three students selected as subjects based on high, medium, and low levels of mathematical ability. Data were collected through problem-solving tasks and semi-structured interviews to comprehensively understand the students' approaches and strategies. The results showed that students with high procedural skills implemented problem-solving steps in a structured manner, while those with moderate skills often needed to be more consistent in recording critical steps. Students with low skills tended to bypass procedural structures and proceed directly to solutions, leading to a higher rate of errors. Error patterns varied by students' mathematical ability levels: high-ability students made no errors, medium-ability students exhibited errors in illustrations and procedural consistency, and low-ability students struggled with writing expressions and fully implementing steps. These findings emphasize the need for instructional approaches tailored to students' skill levels, such as structured learning and scaffolding, to strengthen procedural skills. A follow-up study with a broader sample is recommended to validate these findings and assess the effectiveness of instructional strategies for enhancing students' procedural skills across various mathematical topics.

This study investigated the characteristics of seventh-grade students’ mathematical conceptual understanding of Social Arithmetic and identified the factors influencing that understanding. The study employed a qualitative descriptive approach involving 18 seventh-grade students from SMPN 6 Watubangga. Three students were subsequently selected as key informants through purposive sampling based on variations in their problem-solving strategies, conceptual understanding, and communication abilities. Data were collected through problem-solving tasks and structured interviews and were analyzed using the interactive model of data condensation, data display, and conclusion drawing and verification. The findings revealed that students demonstrated varying levels of mathematical conceptual understanding, which were generally characterized by partial mastery of concepts and difficulties in applying concepts consistently across different problem situations. While some students were able to identify relevant information and recognize fundamental concepts such as percentages and discounts, they frequently encountered computational errors and difficulties in communicating mathematical reasoning. Other students struggled to connect multiple Social Arithmetic concepts, determine appropriate solution strategies, and solve contextual problems requiring multistep reasoning. The factors influencing students’ conceptual understanding included limited mastery of fundamental concepts, difficulties in connecting related concepts, insufficient procedural accuracy, and limited mathematical communication skills.

This study aimed to examine the effect of the jigsaw cooperative learning model on students’ motivation in mathematics learning. A quantitative approach with a pre-experimental design was employed. The population consisted of eighth-grade students, from which one class of 41 students was selected using purposive sampling. Data were collected using a mathematics learning motivation questionnaire. Descriptive statistics were used to describe students’ motivation levels, while inferential statistics using a t-test were applied to test the research hypothesis. The results showed that students’ motivation in mathematics learning before and after the implementation of the jigsaw cooperative learning model was generally at a moderate level. However, the implementation of the jigsaw model resulted in an increase of 80.48% in overall students’ motivation and a 96% increase across motivation indicators. The t-test results indicated that the calculated t-value (5.6774) exceeded the critical t-value (2.02), demonstrating a statistically significant effect of the jigsaw cooperative learning model on students’ motivation in mathematics learning. These findings suggest that the jigsaw cooperative learning model is an effective instructional strategy for enhancing students’ motivation in mathematics.

Mathematical representation is a crucial skill that enables students to express, interpret, and connect mathematical concepts through visual, symbolic, and verbal forms. This study explores the differences in mathematical representation skills between students with reflective and impulsive cognitive styles in solving two-variable linear inequality system problems. Using a qualitative descriptive approach, four high school students were selected based on their cognitive styles through the Matching Familiar Figure Test (MFFT). Data were collected through problem-solving tasks and semi-structured interviews. The findings indicate that reflective students demonstrate strong mathematical representation abilities, particularly in organizing and translating information across visual, symbolic, and verbal representations. They exhibit a structured and analytical approach to problem-solving, ensuring accuracy and coherence in their representations. In contrast, impulsive students struggle with problem organization, symbolic representation, and verbal explanation, often producing incomplete and less structured representations due to their tendency to prioritize speed over accuracy. These results highlight the influence of cognitive style on mathematical representation and suggest the need for tailored instructional strategies. Future research should expand the study to a broader mathematical scope and implement targeted interventions to enhance students' representation skills according to their cognitive characteristics.

Developing students' critical thinking skills has become an increasingly important educational priority in the era of artificial intelligence. Despite the growing use of Augmented Reality (AR) in education, empirical evidence regarding its effectiveness in fostering elementary school students' critical thinking in science remains limited, particularly when integrated with Problem-Based Learning (PBL). This study investigated the effect of AR-assisted PBL on elementary students' critical thinking skills in science. A quasi-experimental design with a non-equivalent pretest–posttest control group was employed involving 62 fifth-grade students (experimental group = 32; control group = 30). Both groups received identical problem-based science instruction on flora and fauna topics, while AR was integrated only into the experimental group. Students' critical thinking skills were assessed using an essay-based instrument developed according to the RED framework (Recognizing Assumptions, Evaluating Arguments, and Drawing Conclusions). Descriptive statistics and inferential analyses were conducted using an independent-samples t-test for the pretest and a one-tailed Mann–Whitney U test for the posttest. The findings revealed that students receiving AR-assisted PBL achieved significantly higher critical thinking scores than those receiving problem-based learning without AR (posttest mean = 81.72 vs. 75.83; p = 0.005), with a moderate educational effect (r = 0.329). These findings suggest that integrating interactive three-dimensional visualization within a problem-based learning environment facilitates scientific reasoning and supports the development of critical thinking beyond conceptual understanding alone. This study contributes to the growing literature on technology-enhanced science education by providing empirical evidence that AR functions most effectively as a pedagogical tool when embedded within inquiry-oriented learning environments. The findings also offer practical implications for designing more interactive and student-centered science instruction in elementary schools.
