Definition of Reading Intervention. Reading intervention is a program, supplementary to an existing literacy curriculum, that is provided to students for the primary purpose of increasing reading levels. Such programs can be administered both in and out of the traditional classroom environment.
One way to help improve comprehension during reading is to prepare students ahead of time. With some prior knowledge about what they will read, understanding is sure to increase. In essence what these activities do is create some prior knowledge that students can activate as they are reading.
