Think-Pair-Share - "This instructional stategy, developed by Frank Lyman (1992), is used to engage all learneres in thinking and talking about a question or issues important to a current area of study. Typically, the teacher begins a T-P-S by posting an important thought question. Students are asked to write their ideas or think about the question, working silently until the teacher calls time (usually two to three minutes). This is the "thinking" phase of the process. In the second phase, pairing, students turn to a peer and exchange their thoughts about the question. In the final phase, sharing, the teacher restates the question for the class as a whole and leads the class in a discussion of the question. The Think-Pair-Share strategy increases the likelihood that all students will engage with the question, will have somethin to contribute to the final discussion, and will be more invested in the outcome of the discussion that they would have been if the question had simply been posed once to the entire class and answered by the first student to raise a hand" (Tomlinson & Strickland p. 357).
