This study deals with the case of education of storytelling with activation of diffuse thinking using mind map. Through this case study, we can confirm that mind map is a useful method for smooth progress of storytelling work and for producing 'meaningful' result for learners. As a result of studying the products of the learner's activities, it was confirmed that the mind map stimulates stimulation for storytelling, theme, transition to new vision, insight into life, and writing to maturity. Through this case study, we were able to reaffirm the fact that mind map encourages diffuse and free thinking which are core functions. Furthermore, it was a meaningful time for both teachers and learners to confirm that it was possible to work on storytelling smoothly. This study suggests that mind map is the work of activating diffuse thinking to create creative ideas, but on the other hand, it is possible to write a story based on a topic that can be done at the level of university student learners.
