THE EFFECT OF USING BAMBOOZLE APPLICATION TOWARDS STUDENTS’ VOCABULARY MASTERY AT SD NEGERI 32/II MUARA BUNGO

Abstract

This study investigates the effect of using the Baamboozle application as a learning media on students’ vocabulary mastery at SDN 32/II Muara Bungo. The research was motivated by students’ low English achievement, particularly in vocabulary, which is crucial for language skills. A quantitative quasi-experimental method was applied using a nonequivalent control group design. Two fifth-grade classes were chosen through cluster sampling, with 30 students in Class VB as the experimental group taught using Baamboozle and 30 students in Class VC as the control group taught with printed media. Data were collected through vocabulary pretests and posttests using 25 multiple-choice questions and analyzed with descriptive and inferential statistics. The findings revealed that the experimental group achieved a higher posttest mean score than the control group, and the Mann-Whitney U test showed a significance value of 0.000 < 0.05, indicating a statistically significant difference. These results suggest that using the Baamboozle application significantly enhances students’ vocabulary mastery and serves as an effective alternative to traditional methods. The study highlights the importance of integrating interactive digital media to foster student engagement and improve language learning outcomes.
