Learning design for the natural resonance concept of the rope system with a “Gambo”

Gambo as a traditional stringed musical instrument from Mbojo tribe (NTB) is increasingly missing its existence among the younger generation. This instrument has never been used as a media for learning physics, even though it can show the phenomena of vibration, waves and sound. This paper aims to explain the learning design of contruction the concept of natural resonance using a gambo system and involving advanced spectrum applications of smartphone and evidence the effectiveness of its implementation based on student understanding about the concept and its responses. The learning activity is guided inquiry which involves 28 senior high school students of Kota Bima grade XI. Data was collected through document studies and concept understanding tests. The results of test were analyzed using descriptive statistics and using the normalized gain test, while the analysis of student responses to learning activities used a likert scale. Based on studies and research results, it was concluded that the learning of the natural resonance concept of the string system using Gambo has been well designed and can be implemented easily and effectively. Understanding of students’ concepts increases significantly, and gets a good response from students.
