Describe crisply and clearly what the end result of the learners' activities will be. The task could be a:
- problem or mystery to be solved;
- position to be formulated and defended;
- product to be designed;
- complexity to be analyzed;
- personal insight to be articulated;
- summary to be created;
- persuasive message or journalistic account to be crafted;
- a creative work, or
- anything that requires the learners to process and transform the information they've gathered.
You may wish to peruse the WebQuest Design Patterns site, which gives specific examples of how instructionally sound Webquests can and should be created.
If the final product involves using some tool (e.g., HyperStudio, the Web, video), mention it here.
Don't list the steps that students will go through to get to the end point. That belongs in the Process section.
