  Twenty-First Century Education is a design of instructional culture that
empowers learner-centered through the philosophy of "Less teaching but more
learning". Due to the development of technology enhance learning in developing
countries such as Thailand, online learning is rapidly growing in the
electronic learning market. ClassStart is a learning management system
developed to support Thailand's educational management and to promote the
student-centred learning processes. It also allows the instructor to analyse
individual learners through system-generated activities. The study of online
learning acceptance is primarily required to successfully achieve online
learning system development. However, the behavioural intention of students to
use online learning systems has not been well examined, in particular, by
focusing specific but representative applications such as ClassStart in this
study. This research takes the usage of ClassStart as research scenario and
investigates the individual acceptance of technology through the Unified Theory
of Acceptance and Use of Technology, as well as technological quality through
the Delone and McLean IS success model. A total of 307 undergraduate students
using ClassStart responded to the survey. The Partial Least Squares method, a
statistics analysis technique based on the Structural Equation Model (SEM), was
used to analyze the data. It was found that performance expectancy, social
influence, information quality and system quality have the significant effect
on intention to use ClassStart.
