In larger groups, time will not allow each participant to rehearse the story. Memory is enhanced by multiple tellings of the same story in the same way. Each pre-story time should include a rehearsal of the previous story. Participants should be encouraged to tell each story in the chronology to outsiders as often as possible. To gain maximum retention and accuracy in repetition there is a minimum and an optimum amount of time allowed between each story in the chronology.
Research shows from five to fourteen days is the best time span between story sessions.
A shorter or longer time span between stories leads to loss of retention and accuracy. The dialog session following the story is critical. It is important for a participant to understand the story and to work through his or her worldview because of the story. This is contrary to the way Judaism handled the oral communication of the Torah. The story must be seen as appropriate for all ages and not just good stories to tell children.
