PROBLEM TO BE SOLVED: To provide an effective educational guidance method by writing on a blackboard for students with difficulties in understanding a learning content because of conventional explanation by the writing on a blackboard in various education institutions in which the content is not always arranged in order and its understanding is not easy in many cases. SOLUTION: In place of the conventional writing on a blackboard in which explanation is described, a new writing method on a blackboard is used, in which an important item is written for each block sectioned by a cross, wherein the plurality of crosses are properly arranged so that only concise keywords are written in well-ordered association with each other, thereby allowing the visual and clear understanding of even a complicated learning content.
