Data analysis used qualitative descriptive percentages from the initial study, cycle I, and cycle II. The activities were designed to stimulate children's language development through playing and exploring with alphabet cards.

This improvement is evident in the decrease of children categorized as Not Developing (ND) from 60% (9 children) in cycle I to 47% (7 children) in cycle II, with no children falling into the ND category in cycle II.

The results indicate that playing with alphabet cards is an effective activity to encourage the language development of young children.
