Mathematical strengths in learning: defining a construct for research and practice

Mathematics education has developed compelling arguments for recognizing learners' resources in mathematical activity, yet the construct these arguments invoke— mathematical strengths —still lacks conceptual precision. Drawing on several intellectual traditions that share a strengths orientation, we propose a working definition of mathematical strengths as resources that are observable or inferable, situation-specific, mathematically productive, and actionable for further mathematical learning. We distinguish mathematical strengths from the related constructs of correctness, ability, competence, and achievement. The argument is illustrated through two second-grade learners' responses to the same multiplication task: Cassandra's incorrect but mathematically productive reasoning and Josie's correct solution, whose productive reasoning may still be overlooked if attention stops at the answer. Together, the cases show that mathematical strengths are neither the opposite of errors nor correctness under another name. The 5A Framework for Mathematical Strengths —Anchor, Attend, Assess, Acknowledge, and Advance—operationalizes the definition as an analytic sequence for warranting claims about learners' mathematical strengths, intended to support research, teacher education, and classroom practice.
