摘要：AbstractThe aim of this study is to determine the effectiveness of a multimedia designed material, named iLab as teaching and learning aids to enhance the understanding of Form Four (16 and 17 years of age) chemistry students about Acids and Bases topic. The study compared the academic achievement of the students who were taught by using traditional method and students who were taught by using iLab. The respondents were 65 students from a secondary school in the district of Batang Padang, Perak Malaysia. The students had different academic profile, which were categorized as good, average and weak. 35 students were placed into the experimental group while the other 30 students were placed into the control group. The samples in experimental group were taught by using iLab during two hours chemistry lesson. On the other hand, the samples in control group were taught without using of iLab. The score from the pre-test and post-test were collected and analysed quantitatively for the research questions. The ANCOVA test showed that there was a significant difference in the academic achievement about Acids and Bases topic between the control and the experimental groups (p<0.05). In conclusion, iLab as teaching aid is successful to enhance the understanding of Form Four students about Acids and Bases topic in chemistry.
