Very few secondary school science teachers in Hong Kong can carry out experiments assisted by computers in their teaching because of the lack of supporting peripherals. Products from apparatus suppliers are very expensive when compared with the limited budget available to any school laboratories. These apparatus generally consist of a basic unit for processing, digitizing and logging of signals and data. The associated accessories and software for different experiments are modularized. Buying apparatus for only a few experiments can cost thousands of dollars or even more. This paper introduces a low-cost general-purposed A/D-D/A card and some multimeters with a RE-232 serial interface to use in physics and chemistry experiments. As these equipment are not tailored for school experiments, some low-priced transducers and several exemplary programmes will be introduced as well. Copyright © 1998 Hong Kong Institute of Education.
