DEVELOPING A MEASURE OF AUTHENTIC ASSESSMENT STANDARD FOR CHILDREN’S DEVELOPMENT AND LEARNING USING MANY-FACET RASCH MODEL

Abstract

The Authentic Assessment Standards (AAS) for young children was developed to provide standard assessment instrument that covers standard learning curriculum and domains of child development based on children’s performance. The purpose of this study is to investigate AAS score reliability and validity on the performance including children’s ability, judges effect and domain difficulty using Many-Facet Rasch Model (MFRM). In this study, data were collected from children aged three and four years by two independent judges and the total measure using data for 60 children. MFRM was applied to analyze the data. The results indicated that all children can perform the task given at different levels depending on the domain and item difficulty. It has been found that judges’ effect in scoring and when item statistics were examined, they fulfilled the purpose of evaluation for young children. Therefore, the present study illustrates a procedure for evaluating and improving such measures using a highly flexible and sophisticated psychometric approach among children by authentic assessment. Standardized measurement tools including documentation with systematic assessment and measurement models were recommended to increase quality of evaluation in early childhood education
