In progressive education children are perceived as :

Progressive education is a pedagogical philosophy, most associated with John Dewey and constructivist thought, that redefines the child's role in the classroom. Instead of treating the learner as an empty vessel to be filled with facts (the older transmission or “banking” model), it holds that children actively build their own understanding through experience, inquiry, and social interaction — so the child is seen as a competent, thinking participant who already carries knowledge and actively constructs new meaning, not a passive recipient.

Applying this to the item: progressive education asks how the child is perceived. Since the philosophy centres on the learner actively constructing meaning from experience rather than passively absorbing it, the matching description is one where children are seen as capable, informed participants who make sense of the world themselves — knowledgeable and meaning-makers.

Contrasted against the other descriptions offered:

• Innocent and dependent reflects an older Romantic/naturalist image of the child as blank and fragile, entirely reliant on adults to be shaped from outside — not the active-agent view progressivism promotes.

• Compliant and capable of only consuming knowledge describes the traditional transmission (“banking”) model that progressivism explicitly rejects — a passive recipient rather than a co-constructor of knowledge.

• Vulnerable and in need of protection reflects a protectionist, paternalistic lens that emphasises safeguarding the child rather than trusting the child's own capacity to build understanding.

Hence, the description consistent with progressive-education philosophy is that children are knowledgeable and meaning-makers.
