In this second special issue on Type II applications of information technology in education, the focus is on classroom integration. This editorial explores some possible explanations for the fact that information technology in schools has not fulfilled its considerable potential. One reason may be that individualized instruction is not part of the subculture of public schooling. This, in turn, may have been caused by the lack of a widespread and effective instructional infrastructure in schools. However, some educators have been able to implement Type II applications of information technology in their educational settings, even without such an infrastructure. The present special issue presents articles by such individuals.
