Public speaking skills are essential competencies for supporting effective communication in educational settings, particularly in helping students understand information, express ideas, and participate actively in learning. This article aims to describe the implementation of public speaking skills to improve effective communication through educational activities and communication training. The activity was conducted online via Zoom Meeting through a webinar entitled Make an Effective Communication for Student, involving elementary school teachers, elementary school teacher education students, and members of the general public. Feedback was collected through surveys, online observations, discussions, and virtual assessments using Zoom Meeting and ClassPoint. The activities included presentations on effective communication, explanations of public speaking principles, vocal exercises, speech preparation, and speaking practice in front of a camera. The results indicated that participants had opportunities to practice communication techniques, identify barriers to public speaking, and develop self-confidence. The identified barriers included fear of making mistakes and lack of self-confidence. Furthermore, the activity emphasized the importance of using simple language, delivering clear messages, providing positive feedback, and creating a supportive learning environment that encourages participation. Therefore, public speaking education and practice can serve as a supporting strategy for developing effective communication in education. Continuous evaluation and improvement are necessary to strengthen participants’ communication skills and support interactive and meaningful learning experiences.
