INNOVATIVE QR CODE-BASED INTERACTIVE TEACHING MATERIALS IN ELECTRICAL CIRCUIT LEARNING

Abstract

This study aims to develop and evaluate the effectiveness of QR code-based interactive teaching materials in improving students’ understanding in Electric Circuit courses. The innovation integrates three key components including educational videos, virtual laboratories, and interactive quizzes via Google Forms into a single system accessible through QR code scanning. The research employed a Research and Development (R&D) approach using the ADDIE model. The participants were 55 students enrolled in the Electrical Engineering Education study program. Expert validation confirmed that the developed materials are highly feasible, with scores of 94.68% for instructional media and 96% for technology utilization. Results from small group trials and field testing showed positive responses in terms of ease of use (90%), interactivity (87%), and content relevance (93%). Quantitatively, a significant improvement in student learning outcomes was observed, with an average improvement of 62.67% in post-test scores compared to pre-test. The effect size (Cohen’s d = 8.70) indicates an extremely large effect. These findings affirm that integrating QR codes as a bridge between printed and digital media significantly enhances the effectiveness of technical education. The study recommends broader implementation of QR code-based interactive materials in vocational and technical education to support self-directed, flexible, and industry-oriented learning.
