In the traditional educational system, students learn only by hearing,seeing, reading, writing and doing. Figure 1 shows a histogram of memory retention rates when studentslearn in this traditional way7. With the advancement of technologies students can now learn in many newand innovative ways.

Students often master the courseand laboratory work associated with courses in the curriculum, but they do not gain acomprehensive engineering experience that requires them to synthesize what they have learnedin their curriculum and extend their knowledge through independent learning that reaches outsidetheir field of study, specifically in the topics of constructability. This is further observed atcommunity colleges where students do not have the opportunity of being immersed in a large-scale engineering academic environment of a four-year institution and frequently lose interest inpursuing further education or an engineering career.This educational gap is systematic among engineering universities.
