A Time-Honored Practice -- Because it Works!
When the Jesuits began opening schools in the 16th century, they of course, taught Latin to the boys that attended. Latin was the language of instruction in universities -- even a living language among European intellectuals, who were mostly, but not all, clergy.
Latin was the gate through which they had to pass to obtain all other knowledge of the subjects then taught: the traditional trivium (grammar, rhetoric and logic) and the quadrivium (arithmetic, geometry, music and astronomy). Of course, Theology capped the university education and was for a long time, the only subject in which one obtained a "Ph.D."
The method the Jesuits used was to require the boys -- at every level -- to compose and perform plays, entirely in Latin.
The method and procedure I am about to present is inspired by their work and is designed for intermediate to advanced classes:
The oral presentation of a dialogue happens on the fourth class session. Along the way, there are numerous opportunities for teachers to assess their work and offer feedback.
