Third Graders' Structuring of Arrays: A Constructive Replication Study

• In Event: Third Graders' Structuring of Arrays: A Constructive Replication Study

Description

Children’s spatial structuring is a critical aspect of their understanding of both area and multiplicative reasoning. Since Battista et al.’s (1998) and Outhred and Mitchelmore’s (2000) studies over 20 years ago, spatial structuring of rectangular arrays have been examined with a wide variety of tasks and protocols. Despite observations that tasks can affect such reasoning, there has not been specific focus on examining how task and protocol structure affect students’ spatial structuring. This paper presents a constructive replication study with third-grade students and the inclusion of eye-gaze data from mobile eye-tracking headsets. Findings confirm previously identified levels, while identifying task features that coincide with higher levels of spatial structuring. Implications and future directions are discussed.
