摘要：While much of the prior information system (IS) research has employed technology acceptance
model (TAM) and theory of planned behavior (TPB) to explain user’s technology acceptance behavior,
most of them use self-reported use intention to develop their investigation. The purpose of
this paper is to empirically examine the validity of behavioral intention’s prediction on actual system
usage under a voluntary context. By integrating constructs of the two closely related theoretical
paradigm (TAM and TPB), we propose an integrated model to investigate the relationship. In
doing so, we used questionnaire to gather the system usage perceptions of students who took an
online management information system (MIS) course at a large Canadian university. At the same
time, we also set up the e-learning system to record students’ actual usage. Using partial least
square (PLS) approach, data collected from 105 students are tested against the model showing a
very good fit with 60% explanation of the behavioral intention. The relationship between the intention
and actual system use however was found to be insignificant and weak. Our study questions
the validity of using self-reported intention to represent system usage and provides insight
into future research directions on technology acceptance behavior.
