<![CDATA[Abstract: This study aims to develop a Wayground-based evaluation instrument for the economics subject of international economic cooperation for class XI MAN 2 Model Medan and to determine its feasibility, effectiveness, and practicality. This study uses the Research and Development (R&D) method with the ADDIE model which includes the stages of analysis, design, development, implementation, and evaluation. Data collection techniques are carried out through observation, interviews, questionnaires, tests, and documentation. The results of the study indicate that the Wayground-based evaluation instrument is declared feasible based on validation by material experts with a V Aiken value of 0.8 in the high category and media experts of 0.823529 in the very high category. The results of the effectiveness test show a significant difference between the experimental class and the control class with a significance value of 0.000 <0.05 and the N-Gain value of the experimental class is 0.675 in the moderate and quite effective categories. In addition, the results of student and teacher responses show a practicality level of 88.25% and 85.93% in the very practical category. Thus, the Wayground-based evaluation instrument is able to become an innovative, interactive, and effective evaluation media in supporting the economics learning process.
