Abstract

This study aims to analyze the effect of implementing the Project Based Learning (PjBL) model on students' ability to solve Higher Order Thinking Skills (HOTS) mathematical problems at SMP Tunas Dharma. The background of this study is based on the importance of higher-order thinking skills in mathematics learning and the need for instructional models that can enhance these skills. The novelty of this research lies in the implementation of the Project Based Learning (PjBL) model to improve students' ability to solve HOTS mathematical problems in basic statistics at the junior high school level, which is examined through HOTS test results and students' responses to the learning process. This study employed a quantitative approach with an experimental design. The research subjects consisted of two classes: an experimental class that received instruction using the Project Based Learning (PjBL) model and a control class that received conventional learning. The study was conducted through several stages, namely the administration of a pre-test, the implementation of Project Based Learning (PjBL) in the experimental class and conventional learning in the control class, and the administration of a post-test to measure students' HOTS mathematical abilities after the treatment. The research instrument was a HOTS mathematical ability test that had been validated and tested for reliability. Data analysis techniques included validity and reliability tests, normality tests, homogeneity tests, descriptive statistical analysis, and the Independent Samples t-test to determine differences in HOTS mathematical abilities between the two research groups. The results showed that the data were normally distributed and homogeneous. Based on the results of the Independent Samples t-test, a significance value of p < 0.05 was obtained, indicating a significant difference between the experimental and control groups. Therefore, it can be concluded that the implementation of the Project Based Learning (PjBL) model has a significant effect on students' ability to solve HOTS mathematical problems.

Abstract

This study aims to determine the effect of mathematics learning assisted by Artificial Intelligence using AI Gemini on students’ mathematical self-efficacy in vocational high schools. This study contributes novelty by specifically examining the use of AI Gemini as an instructional support tool to improve mathematical self-efficacy among vocational high school students, a topic that has received limited attention in previous studies. The study employed a quantitative approach with a quasi experiment design using a posttest-only control group design. Participants consisted of 30 students divided into an experimental class and a control class. The experimental class received mathematics learning assisted by AI Gemini, while the control class received conventional learning without AI assistance. The research instrument used a mathematical self-efficacy questionnaire with a Likert scale adapted from Usher and Pajares. Data analysis employed descriptive statistics and an independent sample t-test using SPSS. The findings showed that students in the experimental class achieved higher mathematical self-efficacy scores than those in the control class. The experimental class obtained an average score of 53.60, while the control class obtained 32.20. The independent sample t-test results indicated a significance value below 0.05, demonstrating that mathematics learning assisted by Artificial Intelligence significantly affected students’ mathematical self-efficacy. AI Gemini supported students in obtaining a more interactive, flexible, and responsive learning experience, thereby strengthening confidence in mathematics learning.

Abstract

Mathematical conceptual understanding is one of the essential competencies that students must possess to face the challenges of 21st-century learning. However, students’ understanding of mathematical concepts, particularly in integer material, is still relatively low. In addition, Android-based learning media that have been developed generally focus only on delivering materials and simple exercises, so they have not been able to facilitate conceptual understanding in an interactive and contextual manner. Therefore, this study aims to develop Kodular-based Intelligent Mobile Learning on integer material to facilitate students’ mathematical conceptual understanding. This study employed a Research and Development (R&D) method using the ADDIE development model, which consists of the Analysis, Design, Development, Implementation, and Evaluation stages. The study involved 35 seventh-grade students of MTs Madani Alauddin, Gowa Regency. The developed product was an Android-based learning application equipped with interactive materials, learning videos, example problems, practice exercises, quizzes, discussions, and automatic feedback features. The validation results indicated that the developed media was highly valid, with material expert validation reaching 89.25% and media expert validation reaching 91.11%. The implementation of the media also showed positive results, with student responses reaching 85.14% and teacher responses reaching 89.27%, both categorized as very good. In addition, the implementation results demonstrated high effectiveness with an N-Gain score of 0.72. The findings indicate that the Kodular-based Intelligent Mobile Learning is valid, practical, and effective in facilitating students’ mathematical conceptual understanding of integer material. Thus, the development of Kodular-based learning media can serve as an innovative solution to support interactive mathematics

Abstract

This study aims to describe the integration of social arithmetic concepts based on the world of work in mathematics learning, analyze the implementation of learning, measure students' conceptual understanding, and examine students' responses and learning motivation. The study used a qualitative approach with a descriptive research type and case study design. The research subjects consisted of 24 seventh-grade female students of MTs An-Nur Al-Huda. Data collection was carried out through observation, conceptual understanding tests, student response questionnaires, interviews, and documentation. Data analysis used qualitative descriptive analysis techniques through the stages of data reduction, data presentation, and conclusion drawing. The results of the study showed that the implementation of learning reached an average of 85.25% with a very good category. The results of the conceptual understanding test showed that 41.7% of students were in the high category, 45.8% were in the medium category, and 12.5% ​​were in the low category. In addition, students' responses to learning obtained an average of 88.2% with a very good category. The interview results showed that students found it easier to understand the concepts of profit, loss, discounts, and percentages because the learning was linked to economic activities and the world of work that were close to their lives. Learning also increases student activity, motivation, and engagement throughout the learning process. Thus, the integration of workplace-based social arithmetic concepts can be effectively implemented and become a contextual, meaningful learning alternative that enhances students' conceptual understanding and motivation.
