Development of A Thematic-Based Performance Assessment Model for the Elementary School Exam in Indonesia

Abstract

This development research aims to develop a thematic-based performance assessment model for elementary school level exams to measure students' skills at the end of the level. The development of the performance appraisal model is carried out by referring to the principle of developing an assessment instrument and adapting the ADDIE development model. The development of the performance appraisal model produces outputs in the form of performance appraisal instruments and Student Worksheets (LKPD) as a guide for students and teachers in carrying out performance appraisals. The product in this development has been tested for content validity, construct validity, and reliability, and field tested to measure students' ability to determine the instrument's quality. In addition, the performance appraisal model developed has also been analyzed for its implementation and effectiveness as a tool for measuring student skills. The results of this study include the following: (a) content validity above 0.80 (high); (b) all of the assessment items/indicators have a loading factor value above 0.60 and can be said to be valid in measuring the performance appraisal construct; (c) reliability of 0.941 (very high); (d) the difficulty or item location is in the range between -2.86 to 1.80 or is in the easy to a difficult category and is accurate for measuring the ability of students in the range -3 to +2; (e) discrimination is in the range of 1.33 to 38.21 with good to very good categories; (f) the overall implementation of the performance appraisal model reached an average value of 97.96% or was well implemented; and (g) the overall performance appraisal model developed in this study has been declared effective (valid/reliable/objective/systematic/practical) in measuring students' skills.
