The current study examined the development of two effects that have been found in single-digit multiplication errors: relatedness and distance. Typically achieving (TA) second, fourth, and sixth graders and adults, and sixth and eighth graders with a mathematics learning disability (MLD) performed a verification task. Relatedness was defined by a…

In this article, the authors discuss 4 critical components of mathematics assessment that relate to instruction: (a) teachers need to be knowledgeable about mathematical standards and align them with assessment; (b) assessment should combine formal and informal approaches to obtain a more authentic picture of students' performance and meaningfully…
