Engineering Design Graphics
As the tools for creating virtual models have evolved, engineering graphics educators have continued to adjust their methods for accurately and consistently evaluating students’ modeling strategies. Some of these methods include using concise rubrics for evaluating models, developing activities where students can evaluate their own models, and using automated electronic evaluation tools. One of the main challenges has been developing a method that clearly informs students about how their models will be evaluated, provides a valid and reliable tool for assessing design intent, and allows faculty to evaluate models in a timely and consistent manner.
During the Fall 2013 semester, a study was conducted to examine the effectiveness of a rubric for evaluating constraint-based solid models. The rubric was created after studying conceptual frameworks and other research related to evaluating constraint-based CAD models. Since only one researcher evaluated the models in this study, it was recommended that a study be conducted where multiple experts evaluated the same models using this rubric.
During the Fall 2015 semester, three faculty experts in constraint-based modeling used the same rubric to evaluate a representative sample of models created by students in an introductory engineering graphics course. This paper will present literature related to evaluating constraint-based solid models and inter-rater reliability, describe the methodology and results of the study, and provide recommendations for further research related to evaluating constraint-based solid models.
