  It is undeniable that people life patterns and technological developments are
interrelated within a supply and demand cycle. In the education world, the
emergence of the internet and mobile technologies has opened the learning
boundaries through the use of mobile learning (m-learning). In Indonesia, the
learning service industry has been begun to enliven the outside school
education sector for almost five years ago. Even though the learning has been
discussed around a decade ago, however, it is still rare studies that discuss
the performance of the m-learning system based on the end-user perceptions in
particular. Therefore, the study may still indispensable, especially from the
perspectives of a developing nation. This paper elucidates the preliminary
stage results of the above-mentioned study, including the results of the model
development and its instrument testing. The DeLone and Mclean information
system (IS) success model was adopted, combined with the individual motivation
and organizational culture theories, and then adapted into the processional and
causal logic of the success model. Around 50 respondent data were collected
online and processed and analyzed based on the outer model assessments of the
PLS-SEM method using SmartPLS 3.0 to know the reliability and validity of each
indicator. The result shows that two of 31 are rejected indicators. The
rejections may be the revision considerations for the next study stages.
Although this may be trivial for experts, the clarity of its methodological
explanations may guide the novice researchers, how to develop a research model
and its instrument testing.
