Validity, Reliability, model, Teacher


This study aims to test the validity and reliability of the IoJEPD model instrument to improve the competence of elementary school teachers. This study uses content validity. Quantitative methods and professional experts are the considerations used in this research. The stage of proving the validity of this instrument is carried out utilizing a validation process involving three experts in the fields of learning, evaluation, and experts in the field of instrument preparation. Validity is carried out in the form of a rating scale, which is shown at the level of agreement of the validator rating on the validation items and the Cronbach Alpha Coefficient to measure reliability. The results showed that: a) 15 items of interview guidelines were valid with a validity index range of 0.883; b) 17 items of valid teacher response questionnaire with a validity index range of 0.877;c) 50 valid pedagogical competency questionnaires with a validity index range of 0.865, and d) 40 valid professional competency questionnaires with a validity index range of 0.838. With Cronbach's Alpha coefficient, the reliability of the pedagogical competency test above is 0.901 and the professional competency test is 0.810. So it can be concluded that the scale is valid and very reliable to measure the professional and pedagogic competence of elementary school teachers.
