Improving Vocational Education with a STEM Approach to Op-Amp Circuit Theory and Practice

This study examines the use of the STEM (Science, Technology, Engineering, and Mathematics) approach in the instruction of operational amplifier (Op-Amp) circuit concepts to students of vocational education. With simulations and exercises done virtually, this study aims to enhance theoretical and practical capabilities of students in the learning of Op-Amp circuits, focusing on inverting amplifiers, non-inverting amplifiers, and summing amplifiers. The study produced STEM-based teaching materials in PowerPoint presentation form, including descriptions of theory, practice examples, sample problems, and quizzes. Findings indicate that incorporating a STEM approach encourages greater student interaction, critical thinking, and problem-solving capacity. Moreover, the online simulations offer an open platform for students to experiment and learn by hand in circuit design and analysis. According to the research, the application of STEM-based education practices has a great capability in improving vocational learning outcomes, particularly in the context of technical disciplines such as electronics.
