The study was conducted in the form of Classroom Action Research (CAR) for two cycles, each consisting of three meetings. Data collection techniques included observation, interviews, and documentation, with a focus on five indicators of language skills: speaking with good language, writing names, communicating with teachers and friends, asking and answering questions.

The average score of children increased from 7.6 (Not Developing) in the pre-cycle, to 16.0 (Developing as Expected) in the first cycle, and reached 23.5 (Developing Very Well) in the second cycle.
