This study aims to determine the effect of using a teleprompter app on the speaking skills of fifth-grade students at SDN Pondok Cabe Ilir 03. This study employs a quantitative approach using an experimental method with a one-group pretest-posttest design. The study sample consisted of 26 students selected using total sampling. The research instrument consisted of a speaking practice test (speech) assessed based on the aspects of pronunciation, intonation, language structure, expression, and fluency. Data analysis was conducted using descriptive statistics, the Shapiro-Wilk normality test, and the Paired Sample t-test. The results showed an improvement in students’ speaking skills, as indicated by an increase in the mean score from 8.88 on the pretest to 15.04 on the posttest. Hypothesis testing revealed a significance value of 0.000 < 0.05, leading to the conclusion that the use of a teleprompter application significantly influences students’ speaking skills. The effect size (Cohen’s d = 2.14) indicates a very large effect. The novelty of this study lies in the use of a teleprompter app as a digital medium that supports the development of elementary school students’ speaking skills in public speaking activities.
