Tell each story. Do not read the stories. Obviously, those who are in the early stages of language learning will read the stories until they can tell the stories. Each dialog session following the story should regularly include a rehearsal of the story by participants wanting to obtain an oral Bible. 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.
