Abstract

ABSTRACT Nikmah, Ema Kholifatul. Student ID Number, 126203211022. 2025. The Effectiveness of Using Educandy Application on Students’ Vocabulary Mastery of Eleventh Grade at SMA Negeri 1 Kalidawir. Sarjana Thesis. English Education Department. Faculty of Tarbiyah and Teacher Training. State Islamic University (UIN) Sayyid Ali Rahmatullah Tulungagung. Advisor Dr. Hj. Nanik Sri Rahayu, M.Pd. Keywords: Effectiveness, Educandy, Vocabulary Mastery Vocabulary is an essential component in learning English as a foreign language. It supports the development of the four language skills: listening, speaking, reading, and writing. Without sufficient vocabulary knowledge, learners may face difficulties in understanding and conveying ideas effectively. A strong vocabulary foundation is therefore necessary to achieve language proficiency and successful communication in English. The formulation of the problem in this research is: "Is there a significant difference in the vocabulary scores of students who were taught with and without the Educandy application at SMAN 1 Kalidawir? " The purpose of this research is to find out whether there is a significance difference on students’ vocabulary scores with and without being taught using Educandy application on the eleventhgrade students of SMAN 1 Kalidawir. This study employed a quasi-experimental method with a pre-test and post-test design, analyzed using quantitative techniques. The population of this research consisted of eleventh-grade students at SMAN 1 Kalidawir, totaling 168 students. The sample included class XI-1 (31 students) as the experimental group and class XI-3 (33 students) as the control group. The research instrument was a vocabulary test administered both before and after the treatment. The data were analyzed using an Independent Samples T-test with SPSS version 30 for Windows. The results showed that the use of the Educandy application was effective in improving students’ vocabulary mastery. The average score in the post-test for the experimental class was 82.10, while the control class had an average of 66.21. Furthermore, the p-value of the Independent Samples T-test was < 0.001, which is lower than the significance level of 0.05, this indicates a significant difference between students taught with and without Educandy, demonstrating the effectiveness of this digital tool in supporting English vocabulary learning.
