The Need for Instrument Development to Measure Teachers' Efficacy in Implementing Classroom Assessment

Abstract

This study aims to discuss the need for instrument development to measure teachers' efficacy in implementing classroom assessment. This study found three conditions for developing teachers' efficacy instrument: to determine teachers' efficacy in implementing classroom assessment, plan teachers' professional development training, and no specific instrument to measure teachers' efficacy in implementing classroom assessment. Therefore, to measure teachers' efficacy in implementing classroom assessment, a comprehensive and up-to-date instrument with higher validity and reliability needs to be developed using the Rasch Measurement Model.
