During the Spring 2011 semester, an engineering graphics literacy assessment was developed by a visiting Fulbright Scholar at North Carolina State University. The assessment was administered in constraint-based modeling courses both at NC State University and Latvia University of Agriculture. Then during the Fall 2011 semester another assessment was administered at Riga Technical University in two courses. Students were asked to model seven parts given in an assembly drawing of a device within a 110 minute class period. The parts in the assembly ranged in complexity from a ball to a valve body. Students were given a ruler to measure parts on the B-size third quadrant (A3 size first quadrant for Europe) drawing and determine sizes of features based on the given scale (2:1). Figure shows the modeling test used in this study for third quadrant projection system. There was a positive relationship between the scores on the activity and the pace at which each student completed the parts. Seventy five students from three universities participated in the test and almost half of them modeled all seven parts in the assembly. There were significant correlations between the scores on the modeling assessment and other measures in the course (final project, final exam, and final course average). This paper summarizes how students performed on the assessment (number of parts correctly modeled, scores, total time, etc.), reports analyses of relationships between their scores on the assessment and other measures in the course, and also presents ideas for future studies. The researchers did not find significant differences between junior-level studies in two universities on scores on the modeling test. Overall, there was a significant correlation between scores on the modeling test and the modeling pace. It is suggested that tests like this could serve as an instrument for quantitative measurement of engineering graphics literacy level.
