Abstract

Amplitude Modulation (AM) is a fundamental concept in analog communication systems and a core topic in vocational electronics education. However, many students struggle to grasp the abstract nature of AM theory when taught through conventional methods. This article presents the development of an innovative instructional model based on Project-Based Learning (PjBL) to support students’ understanding of amplitude modulation through hands-on activities. The learning model guides students in constructing and analyzing AM circuits using basic electronic components and simulation tools. The design process emphasizes inquiry, collaboration, and experimentation, enabling students to explore AM signal behavior in practical contexts. The instructional materials include project worksheets, simulation tasks, and performance-based assessment rubrics. This model aims to bridge the gap between theory and practice, foster technical competencies, and enhance student engagement in vocational high schools. The proposed design is ready for further implementation and validation in real classroom environments.

Abstract

This study explores the influence of study time, parental support, extracurricular activities, age, and participation in tutoring activities on students' Grade Point Average (GPA) achievement. Results show that parental support, in the form of motivation and learning facilities, has a significant influence on improving GPA, while extracurricular activities contribute to the development of learning skills and enthusiasm. Age did not show a direct relationship with GPA achievement, although 16-year-old students tended to have better results. In addition, participation in tutoring activities was shown to have a positive impact through additional study time and deepening of material. This study highlights the importance of synergy between time management, family support, and educational support programs in optimizing student learning outcomes.
