Establish an external validity measure for the QCCS

Establish an appropriate external, related quantum-information-science measure against which Quantum Computing Conceptual Survey scores can be correlated to provide validity evidence based on relations to other variables.

Background

The paper evaluates the Quantum Computing Conceptual Survey (QCCS) through evidence based on test content, response processes, internal structure, and relations to other variables. Although the authors compare undergraduate and graduate students and observe the expected difference in performance, they note that stronger external-validity evidence would ordinarily involve correlating QCCS scores with an established, related assessment.

No well-established quantum-information-science metric currently exists for this purpose. Consequently, determining or developing an appropriate comparison measure remains unresolved and is identified as an open consideration to be revisited when suitable instruments become available.

References

At present, there is no well-established QIS metric against which to conduct such an analysis. This remains an open consideration and should be revisited as appropriate comparison measures become available.
