FCI pre-test comparison: Cuesta College versus UC-Davis

Students at both Cuesta College (San Luis Obispo, CA) and the University of California at Davis were administered the Force Concept Inventory (Doug Hestenes, et al.) during the first week of instruction.

     Fall Semester     Summer Session II
     2008              2002
N    53 students       76 students
low   4                 2
mean 10.8 +/- 4.9       9.1 +/- 4.3
high 24                27

A "Student" t-test of the null hypothesis results in p = 0.0206, thus there is a significant difference between Cuesta College and UC-Davis FCI pre-test scores.

Apparently this semester at Cuesta College, students are slightly more knowledgeable about the Newtonian physics concepts covered in the FCI as UC-Davis students at the start of introductory college physics, at a statistically significant level.

Later this semester (Fall 2008), a comparison will be made between Cuesta College and UC-Davis FCI post-tests, along with their pre- to post-test gains.
