There is nothing in this statutory framework about imposing ideas on children at all. Rather, there are 7 areas which are crucial to development.
Page 8 (to 10?) seem to be important pages on what children should be doing at nursery. Importantly it states that "the development of children’s spoken language underpins all seven areas of learning and development".
It is possible that much would be made of, or read into "Children should be supported to manage emotions, develop a positive sense of self, set themselves simple goals, have confidence in their own abilities, to persist and wait for what they want and direct attention as necessary..." under the expansion of "personal, social and emotional development" (the positive sense of self bit) as a "defence" to support the "research" but that's a reach. Especially against the importance of back-and-forth interactions from an early age for forming the foundations for language and cognitive development, and as development of language is the key to all seven areas:
"Three areas are particularly important for building a foundation for igniting children’s curiosity and enthusiasm for learning, forming relationships and thriving. These are the prime areas:
• communication and language
• physical development
• personal, social and emotional development
Providers must also support children in four specific areas, through which the three prime areas are strengthened and applied. The specific areas are:
• literacy
• mathematics
• understanding the world
• expressive arts and design
Communication and Language
The development of children’s spoken language underpins all seven areas of learning and development. Children’s back-and-forth interactions from an early age form the foundations for language and cognitive development. The number and quality of the conversations they have with adults and peers throughout the day in a language-rich environment is crucial. By commenting on what children are interested in or doing, and echoing back what they say with new vocabulary added, practitioners will build children's language effectively. Reading frequently to children, and engaging them actively in stories, non-fiction, rhymes and poems, and then providing them with extensive opportunities to use and embed new words in a range of contexts, will give children the opportunity to thrive. Through conversation, story-telling and role play, where children share their ideas with support and modelling from their teacher, and sensitive questioning that invites them to elaborate, children become comfortable using a rich range of vocabulary and language structures"
