Rasch Model for Validation a User Acceptance Instrument for Evaluating E-learning System
Abstract: Advances in science
and technology, especially Information and Communication Technology (ICT), has
great impacts on the present education management. It allows the development of
the e-learning system to facilitate the teaching and learning processes. As a
result, many modern universities have developed and utilized the system. For
that reason, there is a great need to develop an instrument in which the
elearning management system can be evaluated from various aspects such as the
system performance, user acceptance, and utilization. The level of the user
acceptance is the central focus of this study, known to be strongly related to the
level of utilization, and is widely studied by using the famous framework of
Davis’ Technology Acceptance Model (TAM). The framework is also adopted in the
current study and the required data to analyze quantitatively the model are
selectively obtained from a sample of 73 respondents. The validity and
reliability of the data are evaluated by using the Rasch model. The results
suggest that the all 16 items in the questionnaire are valid and reliable to
measure the acceptance of thee-learning system.
