This document should be written with the student as the intended audience. Write a short paragraph here to introduce the activity or lesson to the students. If there is a role or scenario involved (e.g., "You are a detective trying to identify the mysterious poet.") then here is where you'll set the stage. If there's no motivational intro like that, use this section to provide a short advance organizer or overview. Remember that the purpose of this section is to both prepare and hook the reader.
It is also in this section that you'll communicate the Big Question (Essential Question, Guiding Question) that the whole WebQuest is centered around.
