PENGEMBANGAN GAME BASE ASSESSMENT B-BLOK DENGAN PENAMBAHAN FITUR PERFORMANCE METRIC

B-Blok Game is a game-based assessment that focuses on assessment related to integer arithmetic operation material for junior high school students. In previous research, the B-Blok game succeeded in providing a new approach to working on paper-based exam questions, but the research did not explain how to present the final results of the B-Blok game. This study focuses on developing a performance metric feature for the presentation of the final game results that can provide feedback to the player directly related to his ability to solve integer arithmetic operation problems. In a survey conducted on the developed features, it was found that in the category of learnability it was 81.4%, presentation was 85.4%, error was 76.2%, navigation was 84.3%, perceived usability was 83.7%, perceived usefulness was 85%, and satisfaction was 82.9%. These results show that the performance metric feature in the B-Blok game is positively evaluated and has the potential to become an interactive assessment tool in arithmetic learning.
