Final answer:
Marie Jean Philip fought for the Deaf Education Access Law, which was established in 1988, ensuring language and communication access for deaf children in educational settings.
Step-by-step explanation:
Marie Jean Philip was a strong advocate for the rights of deaf individuals and fought hard for legislation that would improve their chances for education and equality. The law she is most associated with is the Deaf Education Access Law, which was established in 1988. This law is significant as it acknowledged the language and communication needs of deaf children and mandated that deaf children have the opportunity to learn in an environment where their language and communication mode - such as American Sign Language (ASL) - is fully accessible. Although the Americans with Disabilities Act (ADA) and the Individuals with Disabilities Education Act (IDEA) are related pieces of legislation ensuring rights and access for individuals with disabilities, it was the Deaf Education Access Law of 1988 that Marie Jean Philip is closely associated with in her advocacy work.
