Abstract

Abstract – Group projects are often key to engineering design courses since they simultaneously develop teamwork and communication skills in the context of solving difficult engineering problems. However, fair, consistent, and transparent grading of these projects are difficult to achieve, and the individual contribution of students can likewise be difficult to evaluate.
 Standardized marking rubrics are often used to increase the consistency and fairness of project evaluations; however, these frequently lack a systematic means for evaluating individual effort within group work. Rubrics also are difficult to employ when there are numerous possible solutions and where some solutions are more elegant or challenging when compared to others.
 To provide a consistent accounting of individual effort and the difficulty of a submitted group design solution, a three-tier marking rubric was developed. Comparing the project grades between two cohorts in the same course showed that there was a broader distribution of grades when using the three-tier marking scheme.
