Abstract: This study concerns developing an educational system platform that supports Educational Robotics (ER) activities in elementary schools and is based on a storytelling teaching-strategy that provides abundant learning context. In this study, an educational system that accelerates the interactive learning activities of sharing and collaboration was developed. Teachers can use the developed platform to easily establish and operate an educational system that is suitable for the educational activities they wish to conduct. Regarding the students they can use the educational system to share the solutions to their tasks with their classmates and collaborate in order to make further progress. Additionally, the educational system was developed so that it can function on diverse IT devices such as smartphones which enhances its accessibility. Based on the evaluations of 10 teachers on the usability of the educational system along with its levels of operation, the results were shown to be positive.
