This quantitative research study reports the effectiveness of demonstrations supported by appropriate information and communication technology (ICT) tools such as dataloggers, animations and video clips on upper secondary school students' attitudes towards the learning of physics. A sample of 94 secondary four express stream (age 16 years) and secondary five normal stream (age 17 years) physics students from four physics classes of a secondary school in Singapore was selected to participate in the study. A pretest-posttest quantitative experimental design was used. The results indicated that, for both the express and normal streams, attitudes towards the learning of physics improved significantly with the use of demonstrations supported by the appropriate use of ICT tools. The implications of the results in the physics curriculum and other science subjects are discussed.
