FCI pre-test comparison: Cuesta College versus UC-Davis (fall semester 2013)

Students at both Cuesta College (San Luis Obispo, CA) and the University of California at Davis were administered the 30-question Force Concept Inventory (Doug Hestenes, et al.) during the first week of instruction.

*Excludes students with negative informed consent forms (*.pdf)

Student's t-test of the null hypothesis results in p = 0.64 (t = -0.473, sdev = 4.91, degrees of freedom = 148), thus there is no significant difference between Cuesta College and UC-Davis FCI pre-test scores.

Later this semester (fall 2013), a comparison will be made between Cuesta College and UC-Davis FCI post-tests, along with their pre- to post-test gains.
