Computer Scoring of a Visual-Motor Assessment

• In Event: Refining Computerized Testing: Precision, Validity, and Innovation in Educational Measurement

Abstract

Visual-motor functioning has been implicated in a variety of disorders, making accurate visual-motor assessment an essential diagnostic tool. We have developed a computer-scored app for the iPad to eliminate the inaccuracy of human scoring. This study addresses the empirical question whether visual-motor functions using the iPad are similar to visual-motor functions using pencil-and-paper. This study explored similarities and differences in drawings of geometric shapes across three conditions: 1. Traditional pencil-and-paper, 2. Stylus on iPad, and 3. Finger on iPad. Results indicate remarkable similarity in drawing produced in all three conditions, as well as substantial shared variance among geometric stimuli. These findings support visual-motor assessments using technology, and the possibility of accurate measurement with relatively few stimulus items.
