PROBLEM TO BE SOLVED: To provide a learning material analysis program or the like that specifies parent-child relation between learning units by analyzing learning texts included in the learning units.SOLUTION: A learning material analysis program executes: a step by a similar distance calculation part 11 which has a learning material storage part 10 for associating and storing learning periods and learning texts for each learning unit, and calculates a similar distance between learning texts for each pair of learning units; a step by a similar distance determination part 12 which determines whether a similar distance is equal to or less than a predetermined threshold for each pair of learning units; and a step by a parent-child relation specification part 13 which compares learning periods with respect to a pair of learning units determined to be true, and specifies parent-child relation such that a learning unit whose learning period is earlier is a parent unit and the other learning unit is a child unit.SELECTED DRAWING: Figure 2
