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.

Cuesta College UC-Davis

2007 2002
N 35 students 76 students
low 3 2
mean 9.1 +/- 3.9 9.1 +/- 4.1
high 19 27

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.
