| Summary: | This paper is exploring on maneuver to improve research instrument
reliability in scientific research related to Educational Technology by
analyzing the traditional Cronbach’s alpha reliability using SPSS software and
the newer statistical tool, AMOS using Construct Reliability (CR) approach.
Two sets of data were used as sample to perform the comparison. The first set
of data is from a research involving Technology Enhanced Learning Environment.
The second data are sampled from research in digital competency. Finding
from this paper concluded that, conventional approach of using Cronbach’s
alpha have lower reliability than the newer approach of using CR. Using
Cronbach’s alpha show tendency toward measuring consistency instead of reliability.
CR offer better definition of reliability and give a robust measurement
of reliability in research. This paper had shed light into offering alternative approach
to the commonly and widely uses of research reliability especially when
it involves questionnaire as instrument. |
