UNDERSTANDING PEER AND TEACHER ASSESSMENT ABOUT LABORATORY SKILL ON FORMATIVE ASSESSEMENT THROUGH SCIENTIFIC APPROACH

Abstract

In order to obtain a holistic view of students’s contribution peer assessment used in addition to teacher assessment to arrive at overall course grade of a students in scientific approach. However, students based assessment to determines final value still lots raises questions. Although, literature shown student based assessment useful to review and evaluate the right skills in scientific approach, but assessment between students and teacher have different perceptions toward viewpoints in assessments. Therefore, the aim of this study was to identify differences and similiarities between peer assessment and teacher assessment.
