Reading activities and after-reading-programs were applied to students of 4 school years from 2 to 5 school year who read subject books separately, in order to activate reading activities after reading. After-reading-programs make, supply and utilize analytical reading materials of subject books for 5 days of reading camp and that consist of composition of impressions of the book, presentation of that, reading discussion and a picture of impressions of the book. The results show that ,most of all, composition describing their impressions of the book contributes to activation of reading activities after reading very much among four types of after-readings. The next, reading discussion is effective and presentation is also good. But a picture of their impressions of the book does not yet promote activation of after reading activities.
