The problem this research addresses is the low expressive language skills and limited learning activities among young children due to conventional learning practices. In addition, the use of less interactive learning media results in children's engagement in the learning process being suboptimal. This study aims to analyze, evaluate, and demonstrate the effectiveness of the Quantum Learning model, assisted by PowerPoint-based emoticons, in improving children's expressive language skills and learning activities. This type of research is quantitative, with a quasi-experimental, nonequivalent control-group design. The research subjects were 30 children in Group B, comprising 15 children in the experimental class and 15 in the control class. Data collection methods used observation, oral tests, and documentation with observation sheets and performance rubrics as instruments. Data analysis was carried out using descriptive and inferential statistics, including independent t-tests, preceded by normality and homogeneity tests. The results showed a significant increase in expressive language skills and learning activities in the experimental class compared to the control class, with learning completeness reaching 100%. This study concludes that the Quantum Learning model, supported by PowerPoint emoticons, is effective in improving children's expressive language skills and engagement. The implication is that this model can be used as an innovative alternative in PAUD learning.
