Abstract: A learning support system detects an input operation by each user, whenever he operates his terminal apparatus, stores a learning history of each user whenever input operation is detected, learning history including input operation and first time period which is time period from starting time when he starts learning until when input operation is detected, to obtain set of learning histories corresponding to each user and being stored from starting time until when he finishes to learn learning material, retrieves, whenever predetermined time period elapses from starting time corresponding to first user, one learning history, to obtain retrieved learning history whose first time period is equal to second time period from starting time corresponding to first user until when predetermined time period elapses, from sets of learning histories corresponding to second user, and displays retrieved learning history on first user's terminal apparatus.
