UNC-Greensboro's iSchool program enrolled thousands of high school students across North Carolina in Spring, 2011, enabling them to earn college credit. Hundreds of those students enrolled in Conceptional Astronomy, a 200-level course developed by UNC-Greensboro Astronomy Professor Steve Danford.

Brook worked with Danford and two other contributing instructors to adapt their content for a dynamic and interactive online course. He oversaw a 5-person production team to bring the curriculum to life and provided maintenance and support for instructors after the course launched.
