Selecting a General Topic

Identifying a study topic is often the most challenging part of a research project.

Each of the possible study topics has its own set of virtues and shortcomings.

Brainstorming & Topic Mapping

• Begin by creating a long list of possible study topics:– Jot down areas of personal interest– Ask friends / colleagues for ideas– Skim abstracts, journals, and books for inspiration

• What topics emerge as a repeating theme?• What might be enjoyable to explore?
