Description

The article acknowledges the criticism that cutoffs for classifying students' percentage change into categories may seem arbitrary, and answers it: "the cutoffs may come from theory; for example, from expert considerations of what should at least be learned during a course/period of time. Or, they may come from empirical research." When theory is vague and findings rare, illustrative cutoffs may provide a starting point but not a definite definition.

Accounts

• Choose responder-analysis cutoffs from theory or empirical research rather than arbitrarily: The article acknowledges the criticism that cutoffs for classifying students' percentage change into categories may seem arbitrary, and answers it: "the cutoffs may come from theory; for example, from expert considerations of what should at least be learned during a course/period of time. Or, they may come from empirical research." When theory is vague and findings rare, illustrative cutoffs may provide a starting point but not a definite definition. (Zitzmann et al. (2023))

Claims

• The chi-square significance test for NC-DIF is overly sensitive at large sample sizes, requiring an empirical cutoff value [+W]
• Sample selection criteria moderate MLD effect sizes: stricter cutoffs, specificity, and age change group differences [+W]
