AbstractAbstract
We administered the Force Concept We administered the Force Concept Inventory to four different courses at BYU-Inventory to four different courses at BYU-Idaho: two physics courses and two non-Idaho: two physics courses and two non-science courses. The results showed some science courses. The results showed some significant differences, both in student significant differences, both in student demographics (e.g. gender and year in demographics (e.g. gender and year in school) and in conceptual physics school) and in conceptual physics understanding (e.g. self-perception and understanding (e.g. self-perception and attitude towards science), as well as some attitude towards science), as well as some very interesting correlations between very interesting correlations between specific items. specific items.

A steel ball is attached to a A steel ball is attached to a string and swung in a circular string and swung in a circular path in a horizontal plane as path in a horizontal plane as illustrated in the figure illustrated in the figure below. At point P, the string below. At point P, the string suddenly breaks near the suddenly breaks near the ball. If these events are ball. If these events are observed from directly above, observed from directly above, which of the paths 1-5 below which of the paths 1-5 below would the ball most closely would the ball most closely follow after the string follow after the string breaks?breaks?

ConcernsConcerns
Do women not understand physics as well Do women not understand physics as well as men or is the test biased against as men or is the test biased against women?women?
Why are so few women taking physics?Why are so few women taking physics? Do physics students have a better Do physics students have a better
understanding of conceptual Newtonian understanding of conceptual Newtonian Physics than non physics students, or are Physics than non physics students, or are non-physics students not applying their non-physics students not applying their knowledge because of contextual knowledge because of contextual dependency?dependency?
