Authentic-Peer Assessment Instrument to Measure the Ability of A Chemistry Teacher Candidate Evaluation on Basic Chemistry Small Skill Laboratory Works

Abstract

The dominance of paper and pencil assessment tests in chemistry small skill laboratory works make assessments in the affective and psychomotor less attention. This research aims to develop an authentic-peer assessment instrument to measure the ability of a prospective evaluation of chemistry teachers on basic chemistry small skill laboratory works. The method used research and development. The subjects were students of the second semester of chemistry education 2018 at Walisongo State Islamic University Semarang. Data collection instrument in the form of sheets validation instrument to measure the validity and reliability of peer assessment and questionnaire responses sheet learners. The results of authentic-peer assessment developed very validly in the category with a value of 31. The internal consistency reliability Spearman-Brown gained 0.78 means indicates that the authentic assessment instruments developed have a strong level of consistency. The measurement results evaluation capabilities candidate chemicals are known educator excellent ability group with a percentage of 31.45%, a good ability with the percentage of 47.48%, enough ability with the percentage of 15.79%, and less ability with the percentage of 5.28%. The questionnaire results obtained by 82 percentage points. The results of that study concluded that authentic assessment developed meet the category of valid, reliable, and practical.
