摘要：This study reports the effectiveness of nanoscience activities in enhancing secondary
school students’ understanding of two chemistry concepts: structure of atom and acid
and bases. For the purpose of this study, quasi experiment was employed to 163 Grade
10 students from the Northern Region of Malaysia. Sample from the experimental
group was exposed to a series of nanoscience activities lasted for 10 weeks. Students’
understanding on the two chemistry concepts was tested using Chemistry
Achievement Test (CAT). The CAT consists of multiple-choice questions and openended
questions. Data obtained from CAT was analysed using one-way ANCOVA to
identify the effectiveness of nanoscience activity in enhancing students’ understanding
of chemistry concepts. The findings show that there were statistically significant
differences between experimental and control groups’ mean scores (F (1,160) = 167.82,
p < 0.05 ηp
2 = 0.512) with the experimental group students reporting higher mean. The
ANCOVA result indicated experimental group students’ understanding of chemistry
concepts significantly higher than the comparison group. The qualitative analysis of
open-ended responses further supports findings obtained from the quantitative
analysis. The study suggests that integrating nanoscience into the contemporary
teaching of chemistry is relevant and appropriate.
