Investigative activities with data-logging in physics education

There should be no doubt that data-logging can increase the scope of physics experiments in schools. It can measure something that cannot be measured before. The focus of this paper is not on more data recording experiments but on collecting data for more investigative activities. Two activities from dynamics are taken as exemplars to demonstrate how to facilitate students to develop their skills in experimentation，data analysis and hypothesis testing etc. Copyright © 2003 Hong Kong Association for Science and Mathematics education.
