# Brief Biography

Dr. Leatham grew up in Rexburg, Idaho where he attended Madison High School and then BYU-Idaho (known then as Ricks College). He spent two years in France and Belgium (Belgium Brussels mission) as a missionary for the Church of Jesus Christ of Latter-day Saints. He has loved living in Logan, Utah (while attending Utah State University), Athen, Georgia (while attending the University of Georgia), Portland, Oregon (while working at Portland State University), and now in Spanish Fork, Utah. He has been married to Nancy Lynn (Strong) Leatham since 2002 and they are the proud parents of two children and no pets. He enjoys reading, singing, playing the piano, composing music, and playing handball.

# Teaching Interests

Teaching Mathematics with Technology

Calculus

Scholarly Inquiry in Mathematics Education

The Book of Mormon

# Research Interests

Dr. Leatham’s research focuses on understanding how teachers learn to facilitate student mathematics learning. In particular, he studies how teachers learn to use technology in teaching and learning mathematics, how they learn to recognize and use students’ mathematical thinking, and how their beliefs about mathematics, its teaching and learning are related to the learning-to-teach and teaching processes.

He is currently a co-PI on the NSF-funded collaborative research project “Building on MOSTs: Investigating Productive Use of High-Leverage Student Mathematical Thinking“
