The process of evaluation was started by developing the instruments of evaluation by taking into account some related literature. Then, the content validity of the instruments was checked by scientific experts. After that, the assessment was conducted by two groups of experts in a paper-and-pencil format by marking one out of 4 points Likert scale. The result was then analyzed through some justification approaches and indicated that the adaptive e-learning application was categorized acceptable to use in the learning process.
