Using Interview Data from Non-Major Biology Students To Improve the Conceptual Inventory of Natural Selection

Using Interview Data from Non-Major Biology Students To Improve the Conceptual Inventory of Natural Selection
Thesis
Description: 

Full Abstract: The conceptual Inventory of Natural Selection was first published in 2002 (Anderson & Fisher, 2002). Recent research by Nehm & Schonfeld (2008) has raised concern as to whether or not the Conceptual Inventory of Natural Selection (CINS) is effective in assessing students' understanding on concepts related to natural selection. The purpose of this study was to obtain feedback from non-major biology students, through semi-structured interviews, on 12 items that generated low scores or have not paired appropriately on factor analysis on the current version of the CINS. Interviews indicated that improvements needed to be made. The improvements made on the 12 CINS items included word substitutions and minor sentence restructuring to preserve the intent of the original CINS, yet to improve it. Field testing with both biology majors and non-majors showed that the changes were beneficial, although further testing with larger sample sizes is warranted.
