An assessment of performance appraisal in entalphy change laboratory activity: A comparative of scoring by peer and teacher

Abstract

The purpose of this study was to develop performance assessment instruments and their application to high school practicum for enthalpy change. The instrument used is a validation sheet to see the validity. The instrument that has been analyzed is a performance assessment about students' laboratory skills in enthalpy change (ΔH) laboratory activity. The method used in the research was development and validation. The instrument was evaluated by 8 teachers and 32 students of year XI from one of senior high school in Bandung. The result shows that there is a similarity of the score given by students and that the teacher. This similarity is supported by the pearson correlation score r=0,89 have been categorized as very good. This result implies that performance skills can be administered by peers using this instrument since it provide the similar result with the teachers.
