Next, the class will discuss the reading in the target language. With the goal of making the discussion 100% comprehensible, the teacher will use the same TPRS techniques as in step two. Also, the teacher may make use of the pop-up grammar technique, where grammar points contained in the reading are explained very briefly - in 5 seconds or less. A limited number of grammar points are focused on in any particular reading and they are "popped up" frequently to enhance student retention. The discussion can touch on a wide range of topics related to the reading. Usually the teacher will ask questions about the reading itself, and about the students and their lives. Comparing and contrasting the material in the reading to the PQA and the story gives extra repetitions of the target structures. Discussions of culture and even history are possible, depending on the content of the reading and the level of the students.
