This study investigated the noticing of teachers who teach mathematics at different grade levels in the context of lesson study. The study specifically focused on teachers' noticing during the planning phase of the lesson. For this, the lesson planning phase of a group of four teachers consisting of kindergarten and primary school 1st grade…

Legislation such as the No Child Left Behind (NCLB) and Every Student Succeeds Act (ESSA) have emphasized student achievement and test scores. As a result, the landscape of the kindergarten classroom has changed from a more play-based environment to a more academic-based classroom. This shift has caused pre-kindergarten to shift their practices as…

Mid-level roles in education have been widely explored, primarily in schools, but little research has been conducted during the systemic reform that involves creating a mid-level role between end units and the system. The present study explores the sense-making of early childhood leaders (ECLs) at the initial stage of their new role as mid-level…

The instructional hierarchy offers a useful framework for targeting academic interventions. Within this framework, the accuracy with which a student reads might function as an indicator that the student should receive an intervention that focuses either on accuracy or on fluency. The current study examined whether the instructional level for…

To act and think, children and adults are continually required to ignore irrelevant visual information to focus on task-relevant items. As real-world visual information is organized into structures, we designed a feature visual search task containing 3-level hierarchical stimuli (i.e., local shapes that constituted intermediate shapes that formed…

This dissertation tests a dynamic assessment-based cognitive hierarchy model and attempts to identify mathematical concepts that predict student learning potential on more advanced mathematical concepts using the units from ST Math, a self-paced curriculum, for third, fourth, and fifth grade students. The quantitative analyses compared a…
