This study was motivated by the low levels of learning activity, creativity, and expressive language skills among Group B children at TK Hidayah Banjarmasin Timur. The study aimed to analyze the improvement of these aspects through the implementation of Project Based Learning (PjBL), the Talking Stick model, and Big Book media. This Classroom Action Research was conducted in four meetings consisting of planning, action, observation, and reflection stages. The participants were 15 children. Data were collected through observation, interviews, and documentation and analyzed qualitatively and quantitatively. The results showed improvements in all observed aspects. By the fourth meeting, learning activity reached 100%, creativity reached 100%, and expressive language skills reached 93% in the Very Well Developed category. Therefore, the combination of PjBL, Talking Stick, and Big Book media effectively improved children's learning activity, creativity, and expressive language skills.
