Developing, validating, and piloting a MultiTeachViews questionnaire on L1 and translation use: Attitudes of Kazakhstani secondary school EFL teachers.

This study developed, validated, and piloted a MultiTeachViews questionnaire to investigate secondary school English as a Foreign Language (EFL) teachers' attitudes towards multilingual teaching practices such as L1 and translation use. Initially, a literature review and focus group interview with six in-service EFL teachers were conducted to capture prevailing attitudes and inform content areas for the questionnaire. Items were then crafted, followed by the adoption of a 5-point Likert scale. Validation involved assessing internal and content validity through a structured checklist and expert evaluation. The pilot phase included think-aloud protocols with two teachers and a reliability test across a broader cohort of 100 teachers. Reliability testing yielded satisfactory Cronbach's Alpha coefficients (α > .70) for all scales, affirming the instrument's internal consistency. Consequently, the instrument is found to be a reliable and valid measure of EFL teachers' attitudes towards L1 and translation use in the classroom, with significant implications for Applied Linguistic and Second Language Acquisition research.•Developed, validated, and piloted a MultiTeachViews questionnaire for investigating attitudes.•Employed mixed methods in the development, validation, and piloting phases.•Found MultiTeachViews to be a reliable and valid measure of EFL teachers' attitudes towards multilingual teaching practices, such as L1 and translation use.
