Education research: ECCE statistics (spring semester 2015)

Students at Cuesta College (San Luis Obispo, CA) were administered a shortened version (22 out of 45 questions) of the Electric Circuit Concept Evaluation (David Sokoloff, University of Oregon) during the first and the last week of instruction. Physics 205B is the second semester of an algebra-based introductory general physics course covering optics, electromagnetism, and modern physics, with a mandatory adjunct laboratory component.

The pre- to post-test gain for this semester at Cuesta College (excluding students with negative informed consent forms (*.pdf), and missing pre- or post-tests) is:

Physics 205B spring semester 2015 sections 30882, 30883
N = 30
<initial%>	= 31% ± 11%
<final%>	= 40% ± 11%
<g>	= 0.12 ± 0.19 (matched-pairs); 0.14 (class-wise)

This semester's ECCE post-instruction score is slightly lower than results from previous semesters at Cuesta College, and this semester's gain is lower than those in previous semesters.
