Developing the idea-Sketching Early Engineering Design (i-SEED) Scale

• In Event: Science Teaching and Learning: Assessment

Abstract

This study aimed to develop the idea-Sketching Early Engineering Design (i-SEED) Scale to assess pre-college learners’ freehand sketches. Applying the Three-pronged Design Sketching (3-pDS) as a theoretical framework, the purpose of this study was to examine evidence of content validity, construct validity, and internal consistency of the i-SEED Scale data. The data were collected in a residential summer enrichment program for students with gifts and talents at a Midwestern university. A total of 113 design sketches were scored. The sketches were generated by 120 middle- and high-school students in a collaborative design-oriented course. Exploratory factor analysis results supported a three-factor model for the i-SEED Scale, including Visual-Spatial Characteristics, Design Creativity, and Communicating Ideas.
