Abstract

In teaching, media plays an important role in enhancing students' skills. Therefore, digital tools are increasingly necessary. One such tool is Let's Read application, which is an easily accessible learning resource for teaching speaking skills. The purpose of this study is to determine the effect of using Let's Read application on improving speaking ability. The study used a quasi-experimental design, consisting of a control group and an experimental group. The experimental group used digital media from Let's Read application, while the control group used printed stories from the same application. The population of this study consisted of Grade 10 students at MAN 2 Gresik, with the sample comprising classes 10.2 and 10.3, each containing 30 students. Data were collected through speaking assessments, which were administered as both pre-tests and post-tests. The study specifically focused on the use of Let's Read application and extensive speaking activities. Data were analyzed using SPSS version 25. Inter-rater reliability was assessed using a t-test to determine whether there was a significant difference between the scores given by rater 1 and rater 2. Hypothesis testing was conducted using the Mann-Whitney U test, as the data did not meet the assumptions of normality and homogeneity. The findings demonstrated that the inter-rater reliability values (Sig. 2-tailed) obtained from the t-test were all greater than 0.05, indicating that there were no significant differences between the scores assigned by the raters: 0.453 (pre-test experimental), 0.150 (post-test experimental), 0.768 (pre-test control), and 0.397 (post-test control), which means that the data is reliable. Further analysis revealed a significant difference between the control and experimental groups. The mean rank score of the experimental group was 36.72, compared to 24.28 in the control group, indicating that the experimental group performed better. The Mann-Whitney U test produced a significance value of 0.005, which is below the threshold of 0.05, indicating that the alternative hypothesis was accepted. This finding supports the conclusion that Let's Read application is effective at improving speaking ability.
