Abstract

This study aims to analyze the application of the Problem Based Learning (PBL) model on students' mathematical problem-solving abilities in elementary school. This type of research uses a quantitative method with a quasi-experimental design. The instrument used to collect data was an objective essay test. This study involved two groups: a control group using the conventional method and an experimental group using PBL. The research results were analyzed using the Independent Sample T-test with the help of SPSS software. The analysis results showed a significant difference in mathematical problem-solving ability between students using PBL and those using the conventional method. The average score of the experimental group was higher than that of the conventional group. Thus, the implementation of PBL influences the improvement of students' mathematical problem-solving abilities. This study recommends the use of PBL in elementary school mathematics learning to enhance students' learning outcomes and analytical skills.

Abstract

Introduction/Main Objectives: Music education in elementary schools is an essential component of holistic child development, contributing to students’ character formation, creativity, motor coordination, and emotional intelligence. However, the implementation of music learning is often suboptimal due to the limited availability of instructional tools and the lack of engaging teaching methods. This study aims to explore the effectiveness of using the melodica (locally known as pianika) as a concrete and accessible musical instrument to improve students' engagement and understanding in music education. Research Methods: Conducted at SD N 1 Mijen, this research uses a descriptive qualitative approach involving participatory observation, semi-structured interviews with a music teacher and six fourth-grade students, and documentation of the learning process. Finding/Results: The findings indicate that the use of the melodica increases student motivation, enhances comprehension of basic musical notation, and supports the development of performance confidence. Teachers reported that the pianika facilitates structured, step-by-step learning and provides an effective means of formative assessment through direct practice. Students responded positively, becoming more active and enthusiastic during lessons. Additionally, the instrument allowed students to express themselves musically in a collaborative and supportive environment. These results suggest that simple musical instruments like the pianika can serve not only as effective learning tools but also as media that foster emotional and social development. Conclusion: This study supports the integration of practical, engaging, and multimodal strategies in elementary music education to enhance learning outcomes and student participation.
