Ask me once, ask me twice: An initial psychometric analysis of pre-service mathematics teachers’ responses on a retrospective pre-post format of the self-efficacy to teach statistics (SETS-HS) Instrument

This study reports psychometric evidence for using the high school version of the revised Self-Efficacy to Teach Statistics (SETS-HS) instrument in a retrospective pre-post format with for pre-service mathematics teachers. Analyses at the subscale level indicate adequate internal consistency for “before” and “now” ratings and a high correlation between subscale scores across both ratings. Analyses of individual items’ item means, item-subscale total correlations, and the frequency of item mentions in open-ended items are summarized. The retrospective pre-post format yielded SETS-HS scores with some adequate psychometric properties, suggesting a single administration instead of two separate administrations does not degrade the measurements.
