Both research and pedagogy associated with this nexus have been motivated by the awareness of large individual differences as well as international differences in educational attainment. Among the latter (presumably cultural) differences, the latest Trends in International Mathematics and Science Survey (TIMSS, 2003), indicated (a) wide variability in mathematics and science performance, (b) student performance in the United States rated as "below profi cient" on a variety of standardized assessments (Federal Interagency Forum on Child and Family Statistics, 2005), and (c) that an Offi ce for Standards in Education report (OFSTED, 2005) in the United Kingdom surmised that children with below-average abilities in particular were not receiving suffi cient support to be able to overcome academic challenges. In efforts to improve academic opportunities and attainment of children with special needs, legislation in several countries and international efforts by the United Nations and other agencies have sought to proscribe requirements for their inclusion in various educational settings. In the United States, such efforts began with Section 504 of the Rehabilitation Act of 1973 (PL 93-112) and the 1975 Education for All Handicapped Children Act (PL 94-142).
