Answer to Question 2
Joint story-writing might have benefits such as these:
Students can scaffold one another's efforts; for instance, more skilled students can assist those less skilled.
Students can model effective strategies for one another.
Different students might bring different skills to the task. For example, one student may have a particularly creative story line, whereas a second has expertise in punctuation and a third is a careful proofreader.
The combined efforts of the group are likely to yield a more sophisticated story than individual group members can write on their own; as a result, the self-efficacy of all group members may be enhanced.
