Abstract

 Student learning outcomes represent their understanding of subject material and serve as a benchmark for evaluating educational effectiveness. A preliminary investigation at SMA Negeri 7 Gorontalo revealed low student performance in matrix-related mathematics topics. Among various factors influencing learning success, critical thinking stands out as a key internal factor in mathematics education. This study employed a quantitative, descriptive-correlational design with an ex post facto approach. It aimed to assess the mathematical critical thinking skills of Grade XI students and to examine their relationship with learning outcomes on matrix material. Critical thinking was evaluated using four indicators: analyzing, evaluating, explaining, and concluding. Findings indicated that most students had not yet achieved an optimal level of mathematical critical thinking, with an average score of 56.34 across a sample of 50 students. Correlational analysis revealed a significant positive relationship between critical thinking skills and learning outcomes, with critical thinking accounting for 61.62% of the variance in performance. The data suggest that mathematical critical thinking skills play a substantial role in determining student success in matrix material. Given the strong correlation observed, enhancing these skills may lead to measurable improvements in learning outcomes. There is a significant and positive relationship between students' mathematical critical thinking skills and their learning outcomes in matrix material. Efforts to strengthen critical thinking could be an effective strategy to improve academic performance in mathematics.

Abstract

The mathematical problem-solving ability of junior high school students is still considered low, as evidenced by the low learning outcomes among seventh-grade students at SMP Negeri 1 Suwawa. To enhance this ability, an innovative learning model is required. One such model is ICARE, which is believed to encourage active student engagement and foster a deeper understanding of mathematical concepts. This study aims to determine the differences between the ICARE learning model and the conventional learning model on the mathematical problem-solving abilities of seventh-grade students at SMP Negeri 1 Suwawa. The research was conducted from May to June during the even semester of the 2024/2025 academic year. The research method employed in this study was an experimental method involving two classes, namely the experimental class and the control class. Simple random sampling was used to select the samples. The research design utilized was a Post-test Only Control Group Design. The data were collected through a written post-test. The results of the study, based on hypothesis testing using a t-test, showed that the obtained tcount​ = 3.050, while the critical ttable = 2.007 at a significance level of 0.05. Since tcount​> ttable the null hypothesis (H₀) was rejected and the alternative hypothesis (H₁) was accepted. Therefore, it can be concluded that the mathematical problem-solving ability of students taught using the ICARE learning model is higher than that of students taught using the conventional learning model.

Abstract

This study describes students' mathematics learning outcomes in terms of their problem-solving abilities in rectangular material. The research was conducted at SMP Negeri 1 Suwawa in the odd semester of 2019/2020, with 22 students as research subjects. The research instrument used an essay test to measure students 'mathematics learning outcomes and interviews to obtain further information regarding students' mathematics learning outcomes. The indicators used to determine students' mathematics learning outcomes in terms of problem-solving abilities are 1) the ability to understand the problem; 2) the ability to plan problems; 3) problem-solving skills; 4) recheck ability. The results showed that the percentage of completeness of students' mathematics learning outcomes with high problem-solving abilities was 18.18%, the percentage of students' mathematics learning outcomes completeness with moderate problem-solving abilities was 68.18%, and the percentage of students' mathematics learning outcomes completeness with low problem-solving abilities was 68.18%. 13.64%.

Abstract

Purpose: The purpose of this project is to create GeoGebra-assisted learning materials for transformation subjects and to assess their efficacy, validity, and usefulness in enhancing students' mathematical problem-solving abilities. Methods: The five steps of the ADDIE model analysis, design, development, implementation, and evaluation were used in this study's Research and Development (R&D) methodology. Experts in media and materials verified the product, and SMP Negeri 3 Suwawa students in Grade IX participated in both small-scale and large-scale trials. Validation sheets, response surveys, and tests of problem-solving abilities were used to gather data. Gain score analysis and pretest-posttest scores were used to gauge the media's efficacy. Findings: The findings demonstrated that the GeoGebra-assisted learning resources satisfied the requirements for efficacy, practicality, and validity. The product's viability for use in mathematics education was confirmed by expert validation. In both the small-scale and large-scale trials, student replies were 88.90% and 89.23%, respectively, while instructor responses were 95.2%, both of which were classified as extremely practical. The effectiveness test showed that students' ability to solve mathematical problems had significantly improved, as evidenced by the average pretest score rising from 53.33 to 89.89 in the posttest. A high and successful degree of improvement was indicated by the gain score of 0.71 and the gain percentage of 70.74%. Research implications: The created educational materials can be a useful substitute for teaching mathematics, especially when it comes to transformation subjects that call for powerful visualisation. GeoGebra integration offers interactive learning opportunities that improve students' problem-solving skills and help them grasp concepts. Originality: By creating and validating a GeoGebra-assisted learning medium especially for transformation material and methodically assessing its quality using validity, practicality, and effectiveness criteria within the ADDIE development framework, this study advances mathematics education.

Abstract

This study aims to improve students' mathematics learning outcomes in social arithmetic through the implementation of the Project-Based Learning (PjBL) model assisted by GeoGebra-based Ludomatika media in class VII-1 of SMP Negeri 11 Dumoga. This study employed a classroom action research (CAR) design conducted in the 2024/2025 academic year, involving 30 students of class VII-1 as research subjects. The study was conducted in two cycles, each consisting of planning, action implementation, observation, and reflection stages. Data were collected through tests and observations using essay tests and observation sheets for teacher and student activities. The results showed an improvement in students' learning outcomes following the implementation of learning assisted by GeoGebra-based Ludomatika. In addition, teacher activity increased from 77.77% in Cycle I to 83.33% in Cycle II, while student activity increased from 69.70% to 80.60%. These improvements indicate that the implementation of Project-Based Learning assisted by GeoGebra-based Ludomatika can support the improvement of students' mathematics learning outcomes in social arithmetic. Therefore, the use of this media can serve as an alternative to support the mathematics learning process in the classroom.
