This document discusses two teaching approaches: TTT (Test Teach Test) and PPP (Presentation Practice Production). It defines each approach and outlines their stages. TTT involves an initial test to determine students' knowledge, followed by teaching to address gaps, and a final test. PPP moves from the teacher presenting new language, to students practicing it in controlled activities, to freer production. The document notes advantages of each approach, like how TTT bases teaching on test results and PPP encourages independence. It also outlines disadvantages, such as TTT potentially discouraging students or being time-consuming. Examples are given of how to structure lessons for each approach.
