In some classes it is possible, even preferable, to have students explore a range of divergent topics simultaneously.  For example, an assignment in an English class might allow students to write about diverse topics. In a history class, a long-term independent project might offer individual students or small groups the chance to explore a topic of their choice.

Yet another example occurs when a class is studying a topic with so many facets that it isn’t practical to explore it in depth together, such as climate change or the Civil War.  Students can choose from a range of specific subtopics to delve into, master, and report back to the whole class to provide an overview. Even the presentation format can be differentiated—some students may prefer a Power Point-style slide show, others a video, a blog, or some other format.

In any activity that is differentiated by topic, it is best if every student has an active role in choosing the topic.  This requires some scaffolding to help him choose and define the scope of the work he wants to do, and to provide guidance on how to proceed.
