R-QUAF (Rapid Question and Answer Formation) is a device which enables the English as a second language (ESL) class to systematically review previously studied sentence patterns in a brisk and lively way. The technique revolves around a wall chart with cue words for questions running down the left-hand side (to elicit the various structures to be reviewed) and a cast of characters running across the top. The instructor points to a box on the grid thus formed and calls upon a student to make the correct question for that character. For example, "next Sunday - Mr. Redford" would yield: "What is Mr. Redford planning to do next Sunday?" The box contains the answer cue "tennis" or sometimes just a question mark, which would yield "I don't know what he's planning to do." Students have a copy of the chart; they also keep a notebook with sample questions and answers for home study. Additional lines are added to the chart weekly as new structures are covered. The students are always responsible for the cumulative total. (Author/CFM)
