Development of an early grade relational reasoning subtask: collecting validity evidence on technical adequacy and reliability
2020
Overview
Numeric relational reasoning is a foundational mathematical idea for young children and is predictive of future success in mathematics. However, no readily available assessments exist that fully assess relational reasoning in young children. RTI International developed a Relational Reasoning subtask for potential inclusion on the Early Grade Mathematics Assessment (EGMA). Numeric relational reasoning items were developed to focus on equivalence, decomposition, and multiplicative thinking, and both symbolic and visual item formats were utilized. The items developed for the EGMA Relational Reasoning subtask were pilot tested with 1486 students in Grades 2–3. This paper details the characteristics of the Relational Reasoning items developed and validity evidence that was collected to support an assumption about technical adequacy and reliability on an interpretation-use argument.
