q2 i? Item-total reliability analysis of the twelve Likert items yielded an overall Cronbach's alpha of .863, exceeding the .70 threshold. → George Efthimiou 2026

George Efthimiou, Katerina Plakitsi. (2026). Preservice Early Childhood Educators' Engagement with Generative AI in Science Activity Design: The Case of Magnetism. https://www.mdpi.com/journal/educationsciences doi:10.35542/osf.io/m5erf_v1

q2 · i? · associational · r1

Psychometric analysis of the study's 12-item, 5-point Likert reflection instrument (N = 131), reported in the validity and reliability section; the authors state the alpha "surpassed the .70 threshold". Face and content validity were reviewed by faculty.

"An item-total reliability analysis was performed on twelve items on a Likert scale to strengthen the internal consistency and structural integrity of the post -interaction reflection instrument. The overall Cronbach's alpha coefficient was α = .863."
