Dr. Columba's research focuses on facilitating students to make meaning in the mathematics classroom. Recently, she co-authored Vibrant Teaching: An Integrative Approach to Teaching Content Area Disciplines (2018). Also, she coauthored a RtI digital series for K-2, Math of Tomorrow (MOTO) (2013). In each book with four friends (Addison, Mina, Split, and Multiplex), students practice such essential skills as counting, telling time, adding and subtracting, sorting data, and much more. Also, with a team of writers, she co-authored It's TIME: Themes and Imperatives for Mathematics Education (2014), published by the Mathematics Education Leadership NCSM, which is a call to action for mathematics leaders. This leadership framework articulates a set of leadership imperatives and presents a systemic framework to convert our shared vision into a reality of consistently high levels of mathematics learning for all students. In spring 2015, Dr. Columba was elected as the president of the Pennsylvania Council of Teachers of Mathematics (PCTM), a premiere statewide organization for teachers of mathematics, for a two-year term. In addition, Dr. Columba is the President of the Board of Trustees for the Roberto Clemente Charter School.
