Study-reading systems engage students in a sequence of study-reading behaviors for the purpose of reading and remembering content materials such as expository textbooks. They include prereading, during-reading, and post-reading strategies. Study-reading systems that have been reported in the professional literature include SQ3R, OK4R, PQRST, POINT, EVOKER, PORPE, and PLAN, Study reading systems are intended to be student strategies, but require considerable modeling and guided practice by the teacher and in peer-mediated groups before they can be used effectively and independently. For struggling readers who (unlike proficient readers) who do not have a personal study reading strategy, these systems provide a model. Students must make a personal adaptation of the model for it to be useful to them beyond the reading classroom.
