It was in the latter half of 19th century that science began to be introduced into school education in Britain. There was, however, a strong tendency to neglect science as not having the intellectual value. Therefore, it took a good deal of effort for a lot of people to have it accepted as a school subject. Among those, H.Spencer, T.Huxley, H.E.Armstrong played an important role, and especially the work of Armstrong is worthy of notice. This article compares the views on science education by Spencer and Huxley with the view by Armstrong and clarifies the role which Armstrong's view played. The greatest contribution by Armstrong was to bring both the modern education, established by Rousseau and Pestalozzi, which was based on self-activities by children and the modern scientific method based on the experimental research in the laboratory into the unified form of 'Laboratory Teaching' and to establish the contemporary structure of science education in Britain.
