I investigated the relationships between mathematics achievement on the Iowa Assessments and the mastery of four epistemic actions: selecting, analyzing, computing, and representing. These epistemic actions play a crucial role in characterizing mathematical reasoning and are essential for solving mathematics problems in the Iowa Assessments across…

Background/Context: Mathematics education, especially at early grade levels, continues to be an important focus for national education improvement efforts, and more districts are introducing technology as part of their solution. Along with increasing consistent delivery of personalized and individualized learning to students, technology- and…

The aim of this action research study is to determine how differentiated mathematics stations effect student learning. The research question that guided this study is as follows: How does the implementation of differentiated instruction using math stations impact individual student learning progression on the SLO posttest, unit pretest and post…

Evidence-based approaches to assessment design, development, and administration provide a strong foundation for an assessment's validity argument but can be time consuming, resource intensive, and complex to implement. This article describes an evidence-based approach used for one assessment that addresses these challenges. Evidence-centered…

This study is an annotated bibliography of literature dealing with the effects of teaching mathematics by mastery learning. It is subdivided into four areas: History and Development of Mastery Learning; Mastery Learning, an Alternative to Traditional Instruction; Implementation of Mastery Learning; and Studies of Mastery Learning in Mathematics.…

Study examined the ways 117 low-socioeconomic third graders interacted during acquisition of new mathematical skills. The effects of cooperative-mastery-learning (CML) strategies on their mathematics achievement were investigated. Two experiments indicated that students exposed to CML performed better than those given more traditional instruction.…
