Abstract

Assessment and evaluation of student learning outcomes are crucial aspects of education. Effective assessment requires well-designed evaluation test questions, one of them is multiple-choice questions. However, the quality of the multiple-choice questions made must be high. Quality questions are those that have undergone item analysis to assess the validity and reliability of the assessment results for students during the learning process. This study employed an evaluative research methodology with a descriptive quantitative approach. The research subjects involved 251 tenth grade students from two schools in Bombana Regency, Southeast Sulawesi Province. The evaluation was conducted using an instrument consisting of 10 physics questions that were created and validated with the assistance of teachers from each school. These questions covered the topics of the nature of physics, the scientific method, and work safety. The purpose of this study is to analyze the quality of the physics questions to determine whether they meet the criteria or not. Data collection was carried out using the QUEST software and analyzed using the Rasch model. The analysis results showed that the 10 questions had INFIT MNSQ values ranging from 0.77 to 1.33, which are consistent with the Rasch model. Furthermore, the OUTFIT t values for all item questions were obtained at values less than or equal to 2.00, indicating that the questions can be considered usable and passable. The reliability estimate score for the items is 0.98, indicating that this test has high consistency and can be relied upon to accurately measure students' learning outcome.         Keywords: cognitive assessment, rasch modelling, Item response theory.DOI: http://dx.doi.org/10.23960/jpmipa/v25i2.pp671-685

Abstract

This research investigates the physics concepts embedded in the traditional musical instrument "Tamburu" of the Moronene tribe in Southeast Sulawesi, Indonesia. The Tamburu, a traditional plucked string instrument made from layers of bamboo bark, serves as a fascinating case study for exploring physics concepts. The research aims to uncover the connections between the physics concepts applied to this traditional cultural instrument. The methodology combines observational analysis, video recording, and theoretical physics calculations to provide a comprehensive understanding of the sound waves involved in the Tamburu. The results reveal intricate connections between interrelated physics principles, demonstrating how traditional local wisdom can provide explanations for complex scientific knowledge. The research found several connections between physics concepts in the Tamburu, including the concept of sound sources, types of sound waves, frequency, tone (timbre), resonance, and open organ pipes. This research not only highlights the significance of the local culture of the Tamburu but also emphasizes its potential in the field of education as a means of teaching and understanding physics in real-world contexts. This research seeks to integrate the heritage of local wisdom into the educational framework to enrich learning experiences and introduce a deeper appreciation for indigenous knowledge systems.
