It is well known that engineering is considered one of the more demanding fields of study to embark on. In mechanical engineering, courses such as thermodynamics, statics, mechanics of materials and others are perceived as challenging by students. Several factors impact students’ ability to solve problems presented in these courses, including the ability to visualize the abstract concepts presented to them. Exams and homework assignments are among the standard tools used to asses students’ performance and comprehension of course material. Student ability is determined by the quality of the written answers and by how well they document the process used to solve a problem. However, they provide only limited opportunities to reveal the viewing strategies used that may give additional insight into how students initially approach the given problem.
