We propose an association chart production tool called AKaTool. A nursing student learns the association chart to solve a nursing problem logically. In ordinary education, a creation method of the chart is by handwriting, and it spends not only consideration time but also a lot of writing and editing one. AKaTool is used to reduce the chart writing and editing costs for the nursing student. In contrast, a lecturer spends a time to correct the chart written by the student. We implement a highlight function that indicates a path from patient information to nursing diagnosis for lecturer correction support. In this paper, we introduce AKaTool proposed by us, and it is discussed in the experimental result.
