When participants engage twice in the same creative problem-solving task with educational robots, they have the possibility to repeat the same solution, allowing them to complete the task faster, or to show a creative intention and behavior, engaging them in developing a new solution. In this study, we aim to analyze the creative process considering the creative intention and the persistence in the creative process. For this purpose, we engaged 115 adults to perform twice the same problem-solving task using modular robotic cubes without specific instruction concerning the way to solve the task the second time. Creative intention is observed when the participant tests a new solution in the beginning of the second realization of the task, creative persistence behavior is show when participant stay engaged in a new plan although it requires time and efforts. Results show that participants' effective creative solution is related to their creative intention and the time engaged in the second occurrence of the educational robotic task (assessing the creative behavior persistence). These results suggest that the creative process leading to an effective creative solution in a repeated task requires an initial creative intention, but also a higher creative behavior persistence than engaging in a conservative behavior.
