Perception?

In the past few weeks I have given a survey to some of my students, colleagues, and parents.  In the survey, I asked a variety questions about physical education.  One thing that I wanted to find out was the perceptions that others have about physical education.  Generally, a person's perception is linked to their own personal experience.  For example, if a parent had a quality physical education program and teacher during their school days they generally will have a positive perception of physical education as an adult.  Contrary to that, if they were intimidated or belittled in physical education class their perception would probably reflect those negative feelings.  The interesting data from my surveys indicate that 35% of my parents and colleagues said their physical education class could have been better or was the worst.  Meanwhile, in my student survey I did not have one student check that they did not like physical education.  I wonder what the results would look like at the middle and high school levels?  If they do change, why/how is that happening?  My hope is that they continue to enjoy the programs at the middle and high school level so that their perceptions remain positive as they reach adulthood and become our future parents.
