Two of our Noyce Master Teaching Fellows, Katie Garcia and Alicia Davis, had an article published in the December 2013 issue of NCTM's "Mathematics Teacher."
In "Problem Analysis: Challenging All Learners," Garcia and Davis discuss how teachers can modify existing materials to meet new curricular goals, reaching learners at all levels.
Garcia is a teacher at Bryan High School in Omaha. Davis teaches at Scott Middle School in Lincoln.
