This study introduces an innovative augmented reality (AR) environment, augmented by Linibot, a physical robot, to cultivate computational thinking skills in young learners. Integrating AR technology with Linibot, children navigate a grid-like environment on a tablet, guided by the robot through AR obstacles. The objectives include fostering STEM problem-solving, symbol comprehension, and confidence in technology. Pre- and post-tests evaluated the impact on computational thinking in the intervention group of thirty-five children across diverse settings, with a showcase event involving twenty children. Iteratively refined over two and a half years, ongoing analysis of interaction logs aims to assess performance and refine the environment. Preliminary results from five students show significant improvements in task performance, including a 42% decrease in task completion time, an 80% decrease in avoiding difficult problems, and an 80% increase in mission achievements. The tool not only enhances computational thinking but also influences learning behavior, encouraging students to tackle challenges. Future studies will compare control and intervention groups for a comprehensive understanding of the intervention's impact.
