Linear Estimation: Contexts and Spatial Abilities Presentation uri icon

Description

  • This study examined students’ ability to estimate linear measurements. Through a series of different tasks students’ accuracy in estimation was assessed for horizontal versus vertical lengths, raised and flat lines, embedded and non-embedded lines, and 3D and 2D figures. Participants included a sample of 45 middle school students. Results showed that students tended to underestimate vertical and horizontal distances and 2D objects while overestimating raised lines and 3D objects. Spatial ability was significantly correlated with students’ ability to estimate horizontal and vertical oriented objects.
