As a professor of mathematics and mathematics education at Cairn, Dr. Debbie MacCullough’s motivation for teaching math isn’t just the love of numbers.  As a professor, she strives to prepare students in mathematics to better understand, appreciate, and care for the world God has placed them in.  Ultimately, she hopes to help students see mathematics as one way in which to love God and love others better.  In her education courses, she works to prepare mathematics teachers who will endeavor to help students flourish in learning.

In addition to her service at Cairn, Dr. MacCullough is gearing up to conduct research for the Elephant Project, an initiative to develop transformative teacher training in biblical worldview education for over 18,000 Christian schools in the Democratic Republic of Congo.
