Development of Minimum Competency Assessment (AKM) on Chemical Materials

Abstract

This study aims to produce a Minimum Competency Assessment (AKM) instrument on quality reaction rate material in terms of reliability, distinguishing power, validity, and difficulty level. The method used development and validation. The participants were 25 class XII students at Senior High School in Bandung, Indonesia. This research resulted in a minimum competency assessment instrument on response rate material, which consists of six complex multiple-choice questions, five multiple-choice questions, two matching questions, and seven essay questions. The development results of the validity test on the AKM instrument based on the 14 items were declared valid. The empirical validity test results obtained from 8 objective questions and seven descriptive items were declared valid. The test reliability value was calculated using the IBM SPSS 25 Cronbach Alpha application, namely in the objective question of 0.625 with high criteria. In the description question, the score was 0.613, with high criteria. The results of difficulty level analysis items obtained in the objective questions are five questions included in the moderate criteria of 0.30-0.69 and 8 items included in the difficult criteria of 0.00-0.29. The description of 5 items included in the medium criteria of 0.30-0.69 and 2 items included in the difficult criteria of 0.00-0.29. However, the test's difficulty level has not increased proportionately because there are no easy criteria items. The analysis of the discriminatory power items on the objective questions obtained very good criteria, namely nine items of 0.40-1.00. Besides, the description questions that have distinguishing power with very good criteria are four items of 0.40-1.00 and good criteria, namely two items of 0.30-0.39.
