Considerable pedagogical advantage may be gained by the integration of the different ICT tools commonly used in teaching science and technology, particularly by integrating ``real'' and ``virtual'' laboratory activities. In the context of this paper, ``real'' laboratories involve benchtop experiments utilizing data acquisition systems while ``virtual'' laboratories entail interactive simulations and animations. Examples of such integrated activities are described; namely, (i) the study of wave phenomena using sound and (ii) a study of motion in one dimension. Such integrated computerized teaching tools also provide an opportunity for a greater level of integration of different science and technology disciplines.
This paper presents various methods of computer aided experiments in science education and their integration in Web environment as HTML documents. The concept of the virtual laboratory suitable for science teaching at the secondary school level is described. Some essentials and advantages of this approach are presented in the paper. They are illustrated with a concrete example of the course Integrated Science through Experiments that has been developed as a product of the European funded project Computerised Laboratory in Science and Technology Teaching within the Leonardo da Vinci II programme. The paper outlines the structure of the course accessible to the user via a tabular system of links.
