A KWL table, or KWL chart, is a graphical organizer designed to help in learning. The letters KWL are an acronym, for what students, in the course of a lesson, already know, want to know, and ultimately learn.
It is a part of the constructivist teaching method where students move away from what are considered traditional methods of teaching and learning. In this particular methodology the students are given the space to learn by constructing their own learning pace and their own style of understanding a given topic or idea.
The KWL chart or table was developed within this methodology and is a form of instructional reading strategy that is used to guide students taking them through the idea and the text.
