Engineering Design Graphics
The Engineering Graphics Concept Inventory (EGCI) was the first such instrument to be developed with the intent of measuring understanding and misconception in the area of engineering graphics. As technology, methods, and standards continue to change, so too will the content and format of the EGCI. Monitoring the EGCI’s performance against current trends and practices in the area of engineering graphics can help keep the instrument a useful tool in engineering education research. One of the areas that will be observed on an ongoing basis will be the validity of the instrument. Plainly put, validity are measurements of how much an instrument is measuring the variable it claims to be. The convergent validity of an instrument speaks to how correlated two instruments are that claim to measure the same latent ability. It stands to reason then, that a new instrument would correlate positively with an established method of measurement. This study will examine the how well the EGCI correlates with class performance over a series of engineering graphics classes that have instruction on all of the topics assessed in the EGCI. Performance in the class and on the instrument will be compared and analyzed. Currently the instrument is housed on a platform that is institutionally proprietary, and is undergoing a conversion it to a platform that will ensure its sustainability for future use and improvement. The conversion is scheduled to be completed by the end of the 2018 fall semester, and this paper will contain participant data from both the fall 2018 and spring 2019 semesters.
