Application of rasch analysis in measuring teacher collegial supervisory instrument's reliability and validity

The concept of collegial supervision (CS) is defined as collaborative work beyond their professional sphere of relationships often offered by educators through feedback and sharing platform. However, there is still lack of studies and instruments that evaluated the CS practice within Malaysian conte...
