Abstract

This study investigated the effectiveness of a public speaking training intervention for elementary school students. 27 students were assessed on five public speaking aspects: intonation, articulation, facial expression, confidence, and creativity. Students showed greater proficiency in confidence and creativity compared to intonation and facial expression. Hierarchical clustering using Ward's linkage method identified two distinct clusters of students with differing public speaking profiles. The research highlights the benefits of public speaking training for elementary students and the importance of tailoring interventions to address specific weaknesses. The identification of distinct student clusters based on their public speaking abilities provides a framework for developing targeted interventions that cater to individual student needs, promoting effective communication skills from an early age. Future research could explore the long-term impact of such targeted interventions and the relationship between public speaking abilities and other academic and social outcomes.
