Abstract:
The researchers developed the instrument to study teachers' feedback techniques. Using the vast literature, the researcher developed various feedback domains and dimensions, anchoring them to existing scales. These scales do not directly target teachers as respondents. It uses learners as the subject. In this instance, the researchers modified the domains, indicators, and statements of these scales, in addition to the developed concepts from the massive literature. To obtain the validity index of the developed teachers' feedback techniques, three external experts went through the instrument to examine its content, construct, and face validity. Similarly, three internal experts from the graduate school scrutinized the validity of the developed instruments. The researchers calculated validity using the Content Validity Index (CVI) formula. The CVI is.93, indicating excellent CVI values. As a result, it confirms the study's validity in terms of content, construct, and relevance. In this case, the researchers pilot tested the questionnaire on selected teachers. The researchers calculated reliability using the Siegle reliability calculator. The Cronbach's alpha coefficient is.967, which indicates an excellent level of internal consistency.
