Hands-On Training for Chemistry Laboratory in a Ubiquitous Computing Environment

To build an ubiquitous and interactive practical-learning environment in science laboratory at advanced education, educational materials will consist of a large amount of electronic data. With the increase of information in the materials, volumes of data become huge and bandwidth of the network would be oppressed. In order to advance a practical approach, we have to make clear a condition of compatibility between data size and educational effect of the materials. In this paper, we shed a light on minimum requirements for e-Iearning in chemistry laboratory. A relationship between degree of understanding and quality of video materials were investigated using a sample of 1023 first year university students in 8 classes in Japan. Although the students discriminate a frame rate of a video material, they recognized handling and peripheral operation in chemistry laboratory on all rates.
