Abstract
The purpose of this study was to investigate the effect of learning science
laboratory safety using visual signalling principle in a virtual reality environment on
students’ performance, cognitive load and perceived motivation among students with
different spatial ability. A 22 quasi experimental factorial design was adopted in
this research. The independent variables used in the learning of science laboratory
safety were the two modes of courseware which is virtual reality with signalling
(VRS) and virtual reality with non-signalling (VRNS). The moderator variable was
the spatial ability. The dependant variables were the students’ performance,
cognitive load and perceived motivation. The study sample consisted of 141 students
from three schools. All the subjects were randomly assigned to any one of the two
modes of courseware. Descriptive and inferential statistics were used to analyze the
collected data. ANOVA was used to determine the significant differences of the
students’ performance, cognitive load and perceived motivation between the two
groups, as well as the interaction effects of the independent variables on the
dependent variable. The findings of this study showed that the use VRS has shown
better effects when compared to VRNS on students’ performance. More to the point,
visual signalling has also rallied round in reducing students’ intrinsic and extraneous
cognitive load and helps to increase students’ perceived motivation when using
ViSLab courseware. Low spatial ability (LSA) students significantly performed
better, having lower intrinsic cognitive load and extraneous cognitive load, and received higher perceived motivation when using mode VRS. On the contrary,
