The MMaRS team submission, led by PhD student Robyn Pinilla, prepared a poster presentation focused on the iterative design process used to gather validity evidence for K-2 mathematics assessments. The purpose of these assessments is to measure student understanding and skills in numeric relational reasoning and spatial reasoning. Both these foundational concepts are developmentally important for K-2 students. The assessments developed from this work can guide teacher instructional practices.
