12dimensionally (2D) ordered porous arrays using monolayer colloidal crystal templates has the advantageof generating hierarchical structures at micro and nanometer length scales. Polystyrene (PS) beads withthe size of 1 micron were used to form 2D ordered arrays14. The arrays were served as the casting moldsto make Co3O4 hierarchical structures.The external force-assisted nanocasting or spinning concept has been proposed for years15,16,17,18. Thistechnique has been studied for making polymer fibers15,17,19. The principles have also been explored formanufacturing ceramic fibers15,18. By extending the external force-assisted nanocasting process conceptto various material systems, it is possible to synthesize fibers as suitable organic-inorganic

constructability issues. 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.

Questions 1, 3, 6, 7, 8, 10 of the national survey were adapted to better fit the CSUand Cal Poly context of today, while forming the basis of this current study.

design problems. It is important to emphasize here that not all problems are most efficientlysolved using software, so students are taught to solve problems efficiently (i.e. sometimes it isfaster and safer to solve a simple problem by hand than try to input all parameters, make allassumptions, and run the analysis correctly). Typically in the class, students look at solving threemain types of problems: 1- simple problems best solved quickly by hand; 2- problems withsimple, repetitive, but numerous calculations, best solved using either a spreadsheet oralgorithmic approach; and 3- more complicated problems that are most efficiently solved usingengineering software.To ensure uniformity and applicability to subsequent problems, students follow a
