A "Student" t-test of the null hypothesis results in p = 0.97, thus there is no significant difference between Cuesta College and UC-Davis FCI pre-test scores.
The Physics 5A students at Cuesta College found these preliminary results interesting--statistically speaking, they are as knowledgeable about the Newtonian physics concepts covered in the FCI as UC-Davis students at the start of introductory college physics.
Later this semester (Fall 2007), a comparison will be made between Cuesta College and UC-Davis FCI post-tests, along with their pre- to post-test gains.
