A teacher arranges her learners into pairs and give them a text of two paragraphs. One learner in the pair reads out the text to the other and the partner takes the dictation. Then the process is reversed. What is this known as?

Jig-saw dictation is a pair/group activity where each learner has access to part of a text and must dictate their part to others who don't have it; learners then exchange roles. The pair-based reading-and-dictating, then reversing, fits this jigsaw model. Running dictation involves running back and forth to a posted text. Partial dictation involves teacher providing partial text with blanks. Composition dictation involves dictating for composition. Jig-saw best fits the description.
