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

The background of this study stems from the inadequacy of students' mathematical problem-solving competencies alongside the scarcity of instructional materials aligned with the Merdeka Curriculum. Teacher-dominated instruction deprives learners of opportunities for autonomous exploration. Accordingly, this study intends to construct a PBL-anchored instructional package covering geometric sequences and series for phase F that is both valid and practical. An R&D approach employing the 4-D framework was adopted, encompassing define, design, develop, and disseminate stages. Product trials took place at SMKN Pertanian Terpadu Pekanbaru. Three assessors rated validity as "highly valid," yielding 97.44% for the instructional package, 96.18% for student worksheets, and 96% for assessments. The limited-scale trial produced student response rates of 92.38% and teacher response rates of 90.42%, both classified as highly practical. The broad-scale trial produced student response rates of 88.98% and teacher response rates of 91.45%, both classified as highly practical. Drawing on these findings, the PBL-anchored instructional package supporting phase F learners' mathematical problem-solving competencies on geometric sequences and series content has been verified as valid and practical.

Abstract

Difficulties in connecting mathematical concepts with other concepts and real-life situations indicate that students’ mathematical connection ability is still relatively low. One effort to overcome this problem is the implementation of the Problem Based Learning (PBL) model, which emphasizes learning through contextual problems. This study aimed to improve the learning process and enhance the mathematical connection ability of Grade X.7 students at SMA Negeri 4 Pekanbaru on the topic of Systems of Linear Inequalities in Two Variables during the first semester of the 2025/2026 academic year. This study employed Classroom Action Research conducted in two cycles, each consisting of planning, implementation, observation, and reflection stages. The participants were 43 students. The research instruments included lesson plans, observation sheets of teacher and student activities, and a mathematical connection ability test. Data were analyzed using descriptive qualitative and quantitative techniques based on three indicators: connections among mathematical concepts, connections between mathematics and other disciplines, and connections between mathematics and everyday life. The results showed that the implementation of the PBL model improved both the learning process and students’ mathematical connection ability. This was indicated by an increase in the number of students in the very high category from 8 students in Cycle I to 15 students in Cycle II, accompanied by a decrease in the number of students in the low category. The novelty of this study lies in examining the improvement of mathematical connection ability through the gradual implementation of PBL in each action cycle.

To address this issue, the Problem-Based Learning (PBL) model was implemented to improve the learning outcomes of class IX₂ students at Junior High School of YLPI P. Marpoyan Pekanbaru. Engaging 16 students (6 females and 10 males) from the odd semester of the 2025/2026 academic year, this research applied Classroom Action Research (CAR). The study was executed across two distinct cycles, each following a structured sequence of planning, action, observation, and reflection. The learning tools included Learning Objective Flow (ATP), teaching modules, and Student Worksheets (LKPD). The instruments used for data collection included observation sheets for classroom activities and mathematics learning tests. The results demonstrated that the PBL model integration positively affected students' learning outcomes. This was evident from the significant growth in learning mastery, which progressed from 37.5% at baseline to 68.75% and 93.75% in the first and second summative assessments, respectively. Ultimately, the PBL model proves effective in advancing both learning quality and students' mathematical achievement.
