Subclaims¶

q2 i? Rapid-guessing during test taking can distort test scores and adversely affect measurement. → Steven Wise 2020

q2 i? Because rapid guesses do not reflect what a test taker knows and can do, their inclusion tends to negatively distort scores and thereby diminish validity. → Steven Wise 2017

q2 i? If rapid guesses are included in scoring, they introduce systematic measurement errors that can seriously distort scores. → Wise & Kuhfeld 2020

Evidence¶

Steven Wise 2020¶

Steven Wise. (2020). The impact of test-taking disengagement on item content representation. NWEA Research brief. https://www.nwea.org/resources/the-impact-of-test-taking-disengagement-on-item-content-representation/

q2 · i? · theoretical · r?

The brief states as background that "Rapid-guessing can distort test scores and adversely affect measurement." The brief text prints no statistics, samples, or methods supporting this statement.

"Rapid-guessing can distort test scores and adversely affect measurement. New research shows how disengaged responses can also distort content representation."

Wise & Kuhfeld 2020¶

Steven Wise, Megan Kuhfeld. (2020). A cessation of measurement: Identifying test taker disengagement using response time. NWEA Research presentation, National Council on Measurement in Education 2020 virtual conference. https://www.nwea.org/research/publication/a-cessation-of-measurement-identifying-test-taker-disengagement-using-response-time/

q2 · i? · associational · r?

The presentation's description argues that rapid guesses reflect a construct-irrelevant response process and should be excluded from scoring, citing "both data analyses and previous research findings", and states that scoring rapid guesses produces "systematic measurement errors that can seriously distort scores". The description prints no statistics.

"Moreover, if rapid guesses are included in scoring, they introduce systematic measurement errors that can seriously distort scores."

Steven Wise 2017¶

q2 · i? · theoretical · r?

The article's abstract states the consequence of the opt-out conceptualization: "rapid guessing tends to negatively distort scores and thereby diminish validity." The supplied text prints no effect size or supporting dataset.

"As a result, rapid guessing tends to negatively distort scores and thereby diminish validity."

Discussion¶

Related Claims¶

• One measurement article argues that low test-taking motivation biases an individual student's achievement test score downward — the general claim this finding bears on, with the studies behind it

• Disengaged test-taking responses can distort the content representation of test items — related

• Test-taking disengagement distorts both individual and aggregated test scores — related
• Two decades of research have produced advances in both the measurement of test-taking disengagement and understanding of its distortive impact on individual and aggregated scores — related
• E-M scoring assumes the remaining responses are unaffected by disengagement, and this assumption can fail under partial engagement — related
• E-M scoring leaves residual score distortion, suggesting some disengaged test responses are nonrapid rather than rapid guesses — related
• The test platform detects rapid guessing in real time and attempts to re-engage disengaged students to protect score validity — related
• Rapid guessing on achievement tests varies across grades, subjects, and teachers — related
• Academic disengagement behaviors such as chronic absenteeism and course failures are related to test disengagement behaviors such as rapid guessing — related
• Rapid guessing did not appear to substantively affect teacher value-added estimates under the value-added specifications used — related
• Social-emotional factors, including low academic self-efficacy and self-management, are related to rapid guessing behavior — related
• A meaningful percentage of Grade 8 state summative test events showed rapid guessing, varying by subject: 5.5% in mathematics, 6.7% in ELA, and 3.5% in science — a narrower finding that bears on this claim
• Differential rapid guessing often resulted in test events with meaningfully distorted item content representation — related
• Disengaged test-taking rates varied greatly by subgroup, grade, and term in this sample — related
• Rapid guessing differs from solution behavior as a form of test-taker disengagement — a broader claim this one bears on
• Differences in rapid guessing between subgroups generally do not impact substantive interpretations of achievement gaps — a narrower finding that bears on this claim
• Identifying rapid guessing is important for the validity of achievement test scores, particularly with low-stakes tests — possibly the same claim (merge candidate)
• Very short response times (rapid guessing) indicate disengaged test taking in both high-stakes and low-stakes testing contexts — related
• Rapid-guessing behavior varies by item and is significantly related to item length, item position, and presence of ancillary reading material — related
• Rapid guesses on MAP Growth reflect a lack of engagement rather than a lack of knowledge — a narrower finding that bears on this claim
• Rapid-guessing behavior on computer-based tests signals disengaged test taking that threatens score validity — related
• Rapid guessing is a validated indicator of disengaged item responding — possibly the same claim (merge candidate)
• Even a small amount of rapid-guessing behavior can impact institutional rankings — a narrower finding that bears on this claim
• Students scored an average of 4.3 out of 5 on a Markdown quiz after watching the AI-generated videos, suggesting short-term learning — a narrower finding that bears on this claim
• Rapid guesses on computer-based tests reflect a construct-irrelevant response process rather than the tested knowledge, skills, and abilities — related
• Disengaged test taking materially impacts individual state summative test scores but may have relatively minor impact on score aggregations — related
• Test takers generally disengage during only a portion of their items, and these disengaged responses reflect a momentary cessation of measurement — related
• Seriously disengaged initial testers who stopped rapid-guessing on retest showed large RIT gains, averaging about 6 points in Reading and 12 in Math — related
• Rapid-guessing behavior occurs on only about 1% of item responses in a commercially available low-stakes assessment — a narrower finding that bears on this claim
• Rapid guessing can be identified from item-level response time, and its proper interpretation depends on contextual requirements — related
• Differing response styles create a construct-irrelevant source of bias that distorts fundamental inferences made from survey data — related
• Subgroup score differences largely reflect differing opportunities to learn, not inherent group traits — related
• Disengaged responding biases observed scores from achievement tests and surveys in practically and statistically significant ways — a broader claim this one bears on
• Representational pictures enhance test-taker enjoyment, response certainty, and reduce rapid-guessing behaviour — related
• Opting out has disadvantages: it can obscure implicit knowledge, enable excessive opting out, and complicate assessment — related
