Final answer:
The federal government decreased its aid to special education after World War II, but its involvement in special education began to change in the 1960s with the implementation of the Elementary and Secondary Education Act (ESEA).
Step-by-step explanation:
The federal government decreased its aid to special education in the years immediately following World War II. However, it is important to note that the federal government's involvement in special education started to change in the 1960s with President Lyndon Johnson's War on Poverty.
The 1965 Elementary and Secondary Education Act (ESEA) provided funds for developing remedial programs and hiring teachers and aides, which marked a shift towards increased government assistance to special education.
