Significance of the Study
This study is situated in the instrument development and refinement branch of
engineering education research. The construction of an instrument and its rigorous testing
for validity and reliability are crucially necessary precursors to quality research. This
paper contributes threefold to the knowledge base: (1) making transparent the process of
instrument development to ultimately increase the quality of engineering education
research instruments, (2) simplifying the data collection and analysis associated with the
DAET, and (3) contributing to the assessment community a new validation of artifacts
through interviews. Additionally, this triangulation technique can be adapted to other
similar tools (e.g., the Draw-a-Scientist Test; Chambers, 1983). Further research should
examine the coding system in countries and cultures other than the United States.
