Education research: SPCI gains (Cuesta College, Spring Semester 2008)

The Star Properties Concept Inventory (SPCI) was administered to Astronomy 10 (one-semester introductory astronomy) students at Cuesta College, San Luis Obispo, CA during the first class meeting, then on the last class meeting. The results below are class averages for the initial and final SPCI scores (given as percentages, with standard deviations), as well as the Hake normalized gain <g>:

Astronomy 10 Spring Semester 2008 section 4160
<initial%> = 29% +/- 11% (N = 44)
  <final%> = 51% +/- 14% (N = 31)
       <g> = 0.30 +/- 0.16 (matched-pairs); 0.31 (class-wise)

Astronomy 10 Spring Semester 2008 section 5166
<initial%> = 31% +/- 12% (N = 82)
  <final%> = 49% +/- 13% (N = 49)
       <g> = 0.26 +/- 0.20 (matched-pairs); 0.26 (class-wise)

These results are comparable to previous semesters of Astronomy 10 taught by this instructor at Cuesta College.
