The Influence of Miraculous Classiccast Media on the Ability to Express Language in Children Aged 4-5 Years at Kartika Sari Kindergarten Surabaya

Abstract

This study aimed to examine the effectiveness of Miraculous Classiccast media in enhancing the language expression abilities of children aged 4–5 years. Language development at this age is crucial for academic readiness and social interaction, and innovative media can provide meaningful stimulation to support this growth. The research employed a quasi-experimental design with a pretest-posttest control group involving 24 children from TK Kartika Sari Surabaya. Participants were evenly divided into experimental and control groups. The experimental group received learning treatment using Miraculous Classiccast media, while the control group followed conventional teaching methods without media intervention. Data collection was conducted through pretest and posttest assessments using a pop-up book, focusing on three key indicators: understanding the story, answering questions, and retelling the story in their own words. The results were analyzed using the Mann-Whitney U test to determine statistical significance. The findings indicated a significant difference between the experimental and control groups (Asymp. Sig. < 0.05). The experimental group showed improved vocabulary, sentence structure, storytelling skills, and verbal confidence. These outcomes suggest that the interactive and engaging features of Miraculous Classiccast support children's active participation and make the learning process more enjoyable and effective. This research highlights the importance of integrating interactive digital media into early childhood education to enhance children's language development in a fun, meaningful, and participatory way.
