Initial Design Development of Performance Assessment Methods in Planimetry Lectures

Abstract

This study aims to find a suitable format for performance assessment methods applied to planimetry lectures which are expected to improve student learning outcomes. The final product expected from this research is the design of a performance assessment method that can be applied to planimetry lectures. In this study, the research and development method was used. The development design used is the Borg and Gall (2008) model which only adopts 5 steps from the 10 steps of the Borg and Gall model. The subjects involved in this study consisted of 3 experts who gave assessments related to the validity and practicality of the product developed based on the questionnaire given with a score range of 1 to 4 on each item, 10 students (who received treatment) who gave an assessment related to the practicality of the product developed based on a questionnaire given with a score range of 1 to 4 on each item. Based on the development results, the product specifications for the performance assessment method consist of: Tasks that must be completed, the Design of Activities to Complete Tasks, and Rubrics for assessing Tasks that must be completed to assess the process and product of the task. Based on the preliminary test results on the performance assessment model developed, it can be concluded that the performance assessment model developed in the planimetry course is valid and can be used in the planimetry learning process.
