Application of Dynamic Difficulty Adjustment on Evidence-centered Design Framework for Game Based Learning

Evidence-centered Design (ECD) framework has been used to design an effective assessment plan for student. The assessment process often uses game as a tool to make the activity more active, goal-oriented and could give a direct feedback. A difficulty level in the game need to be suitable with student's skill to create a fun, comfortable assessment environment. The result of assessment process usually need some times to be processed and the student could not experience it right away. This paper applies Dynamic Difficult Adjustment (DDA) to create a dynamic game content suitable with the student's skill based on the result of assessment process within the game which is designed using ECD. The presented scheme produce winning rate value of 67%. The students who were participated in the test also find the game to be fun and the dynamic content inside the game could motivate them to use the game to help them learn.
