Improve critical thinking skills using traditional musical instruments in science learning

Abstract

Experiment activity is an essential part of science learning. <em>Suling </em>(flute), a traditional musical instrument from West Java, can be used as a learning media for sound wave concepts. Technology-based mobile can be used as an experimental tool is <em>Phypox</em>. This study aims to report using a combination of <em>Suling</em> and <em>Phypox</em> in experiment activities. The designed activity aims to engage students in critical thinking. The instrument for measuring critical thinking consists of five questions based on the critical thinking aspect: interpretation, analysis, evaluation, inference, and explanation. The study used a one-group pre-and post-test design on 32 8th-grade students at one of the junior high schools in West Java Province, Indonesia. The study procedure is a pre-test, discussion of <em>Suling</em>’s concepts, introduction to <em>Phypox</em> application, experiment activity, presentation, and post-test. Data analysis uses the normalized gain to compare the pre-and post-test. Experiment activities help students to understand frequency, open organ pipes concepts, and investigate the speed of sound produced by <em>Suling</em>. The study found a significant change in the pre-and post-test scores of students after experimenting, so it could be interpreted that the experimental activities using <em>Suling</em> and <em>Phypox</em> affected critical-thinking students.

Local Culture Integration in Physics Experiments: Exploring Angklung with Arduino-Enhanced Frequency Measurement

“…Integrating traditional musical instruments into the physics classroom can create a learning environment that resonates with students' everyday experiences, thus rendering the learning process more meaningful. [17], [18]. Previous studies also found that traditional musical instruments were utilized to illustrate sound concepts to students [12], [19], [20].…”

Biodegradable Battery from Fruit Peels as an Effort to Develop Local Potential-Based Innovative Learning in Elementary Schools

“…Dengan mengenal lebih dekat, peserta didik akan lebih mudah dalam menganalisis potensi lokal yang selanjutnya dapat menjadi sumber belajar peserta didik. Hal ini relevan dengan penelitian yang dilakukan oleh Rahmat dkk (Rahmat et al, 2023) yang menghasilkan temuan bahwa potensi lokal berupa kesenian musik terbukti mampu memberikan pemahaman kepada peserta didik tentang konsepkonsep IPA. Selanjutnya, Chaijalearn, (Chaijalearn et al, 2023) menghasilkan temuan tentang bagaimana mengembangkan kearifan lokal sebagai media pembelajaran dalam meningkatkan keterampilan memecahkan masalah.…”

How Does Local Wisdom in Science Learning? Research Trend Analysis Through Bibliometric in 2018-2023

“…Mengingat pentingnya kearifan lokal dalam pembelajaran, banyak negara yang telah meneliti tentang pentingnya kearifan lokal dalam pembelajaran sains. Di Indonesia, Rahmat dkk di tahun 2023 (Rahmat et al, 2023) menghasilkan temuan bahwa alat musik tradisional (suling) dapat dijadikan sebagai media pembelajaran untuk mengenal konsep gelombang bunyi. Penelitian ini dirancang melalui teknologi berbasis mobile yang bernama Phypox, yaitu mengkombinasikan suling dan phypox dalam kegiatan eksperimen.…”
