THE APPLICATION OF BABY BUS APP WITH ROLE-PLAYING METHOD FOR IMPROVING KINDERGARTEN STUDENTS' LANGUAGE EXPRESSION SKILLS IN CHINA

This study investigates the impact of integrating the Baby Bus educational app with role-playing methodology on improving language expression skills among 30 kindergarten students in Shandong Province, China. Using tests before and after the study along with a satisfaction survey, the results showed a meaningful improvement in vocabulary, sentence building, pronunciation, and confidence in speaking (post-test average = 78.80, SD = 5.41 vs. pre-test average = 69.53, SD = 3.67; t = -11.64, p < 0.001). Participants demonstrated high engagement and motivation through interactive app activities and collaborative role-playing scenarios. The findings suggest this blended approach effectively bridges digital literacy with kinesthetic learning, offering a scalable model for early childhood education reform.
