The average evaluation rating from the experts was at mean = 4.77 and SD = 0.36 which was the highest
level. The system test among 90 students in 3 disciplines found that students in Science and Technology, Health
Sciences, and Humanities and Social Sciences had overall opinions about E-Portfolio Management System at mean=
4.33 and S.D. = 0.67, mean = 4.48 and S.D. = 0.60, mean = 3.88 and S.D. = 0.77, respectively. The sample group
had additional opinions to develop and apply the system in the real situation. In conclusion, the system was very
useful for storing the trace evidence of learning. However, the use of the system was difficult to understand. It was
believed if the users used the system regularly or had an opportunity to use it more often, they would be able to use
the system more effectively. Therefore, in order to enable the system to be implemented, the researcher considered
to add clearer information in the manual and organize training in a timely manner and according to the needs of the
users.
