information systems (system quality, information quality, use, user satisfaction, individual impact, and organization
impact). In this model, system quality and information quality affect use of and satisfaction with the information
system, which then affect individual behavior and, thus, the performance of organizations.
Over the years of development, some scholars have offered different viewpoints and suggestions on this model. Pitt
et al. (1995) claimed service quality also affected an organization’s satisfaction with information systems. DeLone
and McLean (2003) thus extended their original ISSM model (DeLone and McLean, 1992) to include intension to
use in the original definition of “use.” Individual impact and organization impact were combined as “net benefits,” as
shown in Figure 2. This research targets e-Portfolio system users, defining learning satisfaction as the positive or
negative feelings or attitudes users display on the presentation of their e-Portfolio, process and results, to assess their
intension to use the e-Portfolio. Satisfaction is a major factor affecting intension to use such a system.

Conceptual model and hypotheses
From the preceding discussions, the TAM focuses on the level of acceptance users have for a given information
technology, the information technology in this case being defined as e-Portfolio. The two most important factors for
prediction of attitudes and behavior intension are perceived usefulness and perceived ease of use, which are included
in this research as variables to determine whether user acceptance of the system is connected to perceived usefulness
and perceived ease of use. In addition, this research investigates how system quality, information quality and service
quality directly affect user satisfaction based on ISSM. The research structure is illustrated in Figure 3, and we
propose the following hypotheses:

The motivational perspective has also been widely used to gain insight into individual behavior. Pintrich et al. (1989)
developed the Motivated Strategies for Learning Questionnaire (MSLQ) scales and tapped into three areas, including
