Speciation is a core concept in evolutionary biology, yet it is one of the most poorly understood. Numerous major misconceptions are present in student thinking at the undergraduate level and this inventory has been designed to highlight these. The authors are currently designing teaching interventions to accompany the concept inventory as tools for assessing learning gains.

Development Timeframe

From the initial stage of conducting open-ended student interviews, to designing questions, obtaining student validation and, ultimately, expert validation, this inventory is now ready for use. Data have been analyzed from pre and post-course tests run in classes at UBC.

Number of Questions

This inventory features 14 questions addressing concepts such as what a species is, how they originate, and the link between speciation and gene flow.
