Three ideals contained int he NAEYC and DEC codes of ethics that are meaningful for me:
Ethical Responsibilities to Children
I-1.8—To support the right of each child to play and
learn in an inclusive environment that meets the needs
of children with and without disabilities. 
             Principles
P-1.2—We shall care for and educate children in positive
emotional and social environments that are cognitively
stimulating and that support each child’s culture, language,
ethnicity, and family structure.
Ethical Responsibilities to Families
I-2.3—To welcome all family members and encourage
them to participate in the program, including involvement
in shared decision making.  
Ethical Responsibilities to Colleagues
I-3A.1—To establish and maintain relationships of respect,
trust, confidentiality, collaboration, and cooperation
with co-workers
Ethical Responsibilities to Community
and Society
I-4.7—To support policies and laws that promote the
well-being of children and families, and to work to
change those that impair their well-being. To participate
in developing policies and laws that are needed,
and to cooperate with families and other individuals
and groups in these efforts.
Their significance to me:
These ideals revolve around inclusion. I think inclusion is the key to education. So much can be learned when we work with, attempt to understand, and learn from those that are different than ourselves.All of the ideals that are significant to because they promote an environment that supports inclusion, respect, trust, confidentiality, high participation, and more. I think that these ideals are at the heart beat of the field.
