Figure 4 Statistics of Comparative improvement (Questions 13-32)

Post-survey questions 1-12 are related to CFD lab goals and questions (13-32) are related to comparative improvements of students after doing CFD labs to before taking the course. The post-survey results for the Fall 2014, Fall 2013 and Fall 2012 are available and compared. Students used Flowlab software in Fall 2012. Fall 2013 and Fall 2014 were the first and second time the ANSYS software was used, respectively.

For question 1-12, the distribution decreased at “strongly agree” for Fall 2014 (28%) compared with in Fall 2013 (39%) while in Fall 2012 it comprised only 17% of the answers. The accumulative percent of

“strongly agree”, moderately agree”, and “mildly agree” answers add up to 87% in Fall 2014, 92% in Fall 2013 and 77% in Fall 2012, a slight decrease compared with that of last year. The breakdown of answers for questions 1-12 are shown in Figure 2.

For questions 13-32, the distribution slightly decreased at “strongly agree” for Fall 2014 (30%) compared with in Fall 2013 (34%) while in Fall 2012 it comprised only 13% of the answers. The accumulative percent of “strongly agree”, moderately agree”, and “mildly agree” answers add up to 88%

in Fall 2014, 94% in Fall 2013 and 92% in Fall 2012, a slight decrease.
