Students at both North County (Paso Robles) and San Luis Obispo campuses of 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. Physics 205A and Physics 7B are both algebra-based introductory general physics courses covering Newtonian mechanics.
The FCI results of NC and SLO campus students can be compared to each other.

Despite a slightly higher mean score for NC campus students over SLO campus students, a "Student" t-test of the null hypothesis results in
p = 0.20, thus there is
no significant difference between NC and SLO campuses of Cuesta College.
With both NC and SLO campuses of Cuesta College students pooled together, they can be compared to students at UC-Davis.

Despite a slightly higher mean score for Cuesta College students over UC-Davis students, a "Student" t-test of the null hypothesis results in
p = 0.14, thus there is
no significant difference between Cuesta College and UC-Davis FCI pre-test scores.
Later this semester (Fall 2009), a comparison will be made between Cuesta College and UC-Davis FCI post-tests, along with their pre- to post-test gains.
