The present study seeks EFL Student-Teachers (STs) views on two main Grammars of teaching the passive voice in English: a teaching grammar and a linguistic (transformational) grammar. Firstly, a range of exercises on the two grammars were compiled. Next, the Student- Teachers attempted the exercises and then evaluated them. Later, their views were elicited by a questionnaire. After doing the exercises, a large number of Student-Teachers changed their minds about the linguistic (transformational) grammar of the passive. Consequently, the Organic Approach (O.A.) was suggested as a comprehensive teaching grammar.
