SQ3R method is a strategy used in the teaching of reading. Originally designed by an American Educational philosopher, Francis P. Robinson, in 1946 it is named for the five steps that it incorporates into reading study; survey, question, read, recite, review.
These steps are taken in order to focus on comprehension of material read. Unfortunately, there is a sizable population of grade school students who don't comprehend written material beyond the "decoding" stage - that is to say that they can pronounce the words but don't process the actual meaning of the words and sentences. The SQ3R methods try to remediate this by teaching the student to question and review the text in order to understand the meaning.
