Science, Technology, Engineering, and Mathematics (STEM) education has become a key focus in the U.S. government's public education agenda. Many STEM degrees require the successful completion of undergraduate introductory organic chemistry (O-Chem), which is notorious for its difficulty and high attrition rate. Concept Maps (CM) have been used as…

In the first part of this article, the use of Generalizability (G) theory in examining the dependability of concept map assessment scores and designing a concept map assessment for a particular practical application is discussed. In the second part, the application of G theory is demonstrated by comparing the technical qualities of two frequently…

The validity of connected understanding interpretation of three concept mapping techniques was studied, focusing on the correspondence between mapping-intended task demands, inferred cognitive activities, and scores obtained. The concurrent and retrospective verbalizations of subjects at different levels of competency as they performed the mapping…

Developed a framework for examining cognitive validity claims and used it to evaluate the validity of a "connected understanding" interpretation of three concept mapping techniques used by two teachers and six high school students. Results show that the three mapping techniques provide different pictures of student knowledge and suggest that…
