Abstract

Abstracts This study aims to explore the effectiveness of inquiry-based learning in improving students’ conceptual understanding of electrical resistivity within the context of physics education. Many students struggle to comprehend the relationship between resistance, length, and cross-sectional area of conductors, often due to abstract instruction and a lack of hands-on experience. To address this, a classroom-based experimental activity was designed where students investigated resistivity using Ohm’s Law and direct measurements of voltage and current. The participants, consisting of tenth-grade science students, conducted experiments using wires of varying dimensions and calculated resistivity values. Pretest and posttest assessments were administered to evaluate conceptual gains, and the results showed a moderate to high increase in understanding based on normalized gain (N-gain) scores. The findings highlight that inquiry-based methods enable students to engage in authentic scientific practices such as observation, data collection, and analysis. The novelty of this study lies in its integration of low-cost, accessible experiments into structured inquiry learning, proving that conceptual depth can be achieved without sophisticated equipment. The results suggest that applying inquiry-based strategies in physics classrooms can enhance students’ scientific literacy, problem-solving abilities, and critical thinking, contributing to meaningful and effective science education.

Abstract

Penelitian ini bertujuan untuk mengevaluasi pengaruh variasi suhu dan panjang tali terhadap nilai tegangan permukaan air melalui pendekatan praktikum menggunakan metode cookbook. Eksperimen dilakukan dengan mengatur dua tingkat suhu (26°C dan 42°C) serta tiga panjang tali berbeda (0,10 m; 0,18 m; dan 0,20 m), dengan masing-masing kombinasi diulang sebanyak empat puluh kali. Hasil eksperimen menunjukkan bahwa semakin pendek tali yang digunakan, semakin tinggi nilai tegangan permukaan yang diperoleh, terlepas dari suhu air. Namun, ditemukan hasil yang tidak sesuai teori, yaitu tegangan permukaan air bersuhu lebih tinggi justru lebih besar daripada air bersuhu rendah. Ketidaksesuaian ini kemungkinan disebabkan oleh keterbatasan alat pengukuran serta pengamatan visual yang kurang presisi. Walaupun demikian, kegiatan praktikum ini terbukti mampu memperkuat pemahaman mahasiswa terhadap konsep gaya permukaan serta meningkatkan keterampilan mereka dalam melakukan eksperimen dan analisis data.
