The antonyms for mainstreaming education vary, depending on the context. If we consider mainstreaming education as a concept of providing equal opportunities in education for all students, regardless of their disabilities or special needs, then the antonyms would be segregation, exclusion, or marginalization. However, if we consider mainstreaming education as a term for conforming to popular trends or attitudes in education, then the antonyms would be originality, independence, or innovation. In both cases, the antonyms highlight the importance of creating an inclusive and diverse educational environment that respects individual differences, promotes equity, and fosters creativity and critical thinking.
