Final answer:
The least supported statement by the literature is that one-size-fits-all approaches are effective for engaging culturally diverse families, as this contradicts the established need for cultural competence and individualized approaches in education.
Step-by-step explanation:
The statement with the least support from the literature on culturally diverse families is that c) One-size-fits-all approaches are effective for engaging culturally diverse families. This is because culturally responsive education recognizes the need for individual and community-based approaches that respect and incorporate cultural diversity.
and literature support the importance of cultural competence, recognizing diverse family dynamics, and involving families in the education process to enhance student outcomes. Culturally diverse educational practices encourage educators to avoid one-size-fits-all strategies and instead adapt their approach to suit the diverse needs and backgrounds of their students and their families.
