Subclaims¶
Reading the evidence codes
q is the design tier, i the impact, n the sample, and the kind with its r
the rigour judged within that kind: what each code means.
This claim: no standardized effect is recorded in observations/ for it yet, so no benchmark reading is possible.
q1 i? The increased efficiency effect confounds attempts to exploit a speed-ability trade-off, which is central to many of the models discussed by Goldhammer. → Steven Wise 2015
Evidence¶
Steven Wise 2015¶
Steven Wise. (2015). Response time as an indicator of test taker speed: assumptions meet reality. Measurement: Interdisciplinary Research and Perspectives, 13(3–4), 186–188. https://www.nwea.org/research/publication/response-time-as-an-indicator-of-test-taker-speed-assumptions-meet-reality doi:10.1080/15366367.2015.1105062
q1 · i? · theoretical · r2
Theoretical argument: because exhibited speed can change "without a commensurate change in exhibited ability", the usefulness of response time for estimating ability is undermined. This is the author's reasoning, not a tested result; no effect size is printed.
"It confounds attempts to exploit a speed-ability trade-off, which is central to many of the models that Goldhammer discussed. If exhibited speed can change without a commensurate change in exhibited ability, the usefulness of response time in estimating a test taker's ability is undermined."
Discussion¶
Related Claims¶
- The increased efficiency effect threatens the validity of response-time models that presume item response time is influenced only by item time intensity, ability, and working speed — possibly the same claim (merge candidate)
- How commonly the increased efficiency effect is present in test data is unclear — related
- Test takers tend to increase their time efficiency during MAP test events, an effect the author observed in data from 2 very different testing programs — related
- Ability and speed are negatively correlated, and the reading test's ability estimates are more affected by speed than the math test's — related
- Computer-based testing's routine capture of item-level response times has driven increased interest in applications of response time to measuring ability and achievement — related
