Abstract
This study aimed to investigate the effects a virtual science centre using either a free-choice
or a problem-based learning approach, on improving scientific literacy among Form Four
secondary school students. Scientific literacy is defined and measured using three dependent
variables in this study which are general science knowledge, understanding of the nature of
science and scientific reasoning. A model for a virtual science centre, the MYSains Virtual
Science Centre, was developed for the purpose of this study. The sample consists of two
groups of students, with 35 students for the free-choice learning group and 37 students for the
problem-based learning group. The study employed a quasi experimental methodology with
non-equivalent control group pre-test and post-test design. MANCOVA inferential analysis
showed that students from both groups recorded a significant increase in their general science
knowledge, but with no significant change in their understanding of the nature of science and
scientific reasoning, although significant gains were recorded in the free-choice learning
group for scientific reasoning. However, qualitative findings indicate that informal science
learning via a virtual science centre plays a role towards improving scientific literacy among
secondary school students. Positive gains are more evident in a free-choice learning approach
which is less resource demanding and more cost effective. This study demonstrates that the
provision of well designed and developed virtual science centre as shown in the MYSains
model can increase scientific literacy overall with strong gains shown in the acquirement of
general science knowledge with smaller but significant gains in scientific reasoning.
