Abstract

• This study aims to validate a questionnaire measuring the epistemological beliefs of school teachers. In order to study epistemological beliefs, the items were adapted from the questionnaires which are connecting with epistemological beliefs. Based on instruments, Epistemological Beliefs Questionnaire (EBQ), a five-point Likert type self-report questionnaire, is proposed and is investigated to show its validity in a random sample of 436 school teachers. Exploratory factor analysis showed that a five-factor structure of the epistemological beliefs composed of (1) belief in knowledge by experts, (2) belief in certainty knowledge, (3) belief in reasoning knowledge (4) belief in developing knowledge, and (5) belief in effort knowledge. Confirmatory factor analysis further confirmed the validity and reliability of epistemological beliefs as a five-factor construct. This Epistemological Beliefs Questionnaire (EBQ) can serve as a tool to evaluate the epistemological beliefs of school teachers.
