Professional Interests: 

Dr. Darrell Earnest is an Assistant Professor in Teacher Education and Curriculum Studies (TECS) within the College of Education at the University of Massachusetts, Amherst.  His research explores mathematical cognition in school contexts, with foci on learning and teaching as well as professional and curriculum development for elementary school and early childhood.  From a sociocultural perspective, his research considers the design, construction, and/or interpretation of mathematical representations.  He is committed to exploring issues of equity in mathematics education.

Current projects include:

From Number Lines to Graphs in the Coordinate Plane: A Vertical Progression of Mathematical Representations.  This project investigates patterns in students’ problem-solving involving geometric representations of quantities (number line, coordinate plane, function graphs) that, while typically appearing in disparate grade levels, feature structural similarities.  Dr. Earnest will present his research in July/August, 2013, at the Psychology of Mathematics Education conference in Kiel, Germany.

The Mathematics of Time: Investigation of Learning and Teaching.  This exploratory project investigates the learning and teaching of time and its various representations (e.g., analog clock, digital clock, timeline, notation for elapsed time), including translating across hierarchical units (hours, minutes, seconds), and the relation of time to mathematical topics such as measurement, data, fractions, and geometry.
