Initial Development and Validation of the Self-Efficacy for Engineering Design (SEED) Survey for Undergraduate Students in Mechanical Engineering

摘要

This Work In Progress describes the development and validation of a 34-item student-focused Self-Efficacy for Engineering Design (SEED) survey. Content validity was achieved using experts’ judgments. Construct validity was performed using confirmatory factor analysis (CFA). The survey validation was accomplished using 256 mechanical engineering students, distributed over three classes. The SEED survey consists of two subscales that measure the self-efficacy for (a) design competencies (SEDC) and (b) personal competencies (SEPC). SEDC consists of 8 subscales, which are (a) identifying customer needs, (b) establishing target specifications, (c) generating product concepts, (d) selecting a product concept, (e) system-level design, (f) detailed design, (g) prototyping, and (h) evaluating the design. SEPC consists of 4 subscales, which are (a) openness, (b) conscientiousness, (c) extraversion, and (d) agreeableness.
