Change what is expected of primary schools. Children should not be taught about nonsense words, parenthesis, phonemes, adjectives, pronouns, adverbials, model verbs etc as all they should be learning is to read and write, not about how language is formed, that should be for GCSE level.
Children should be learning to love reading and writing, and this will only make it less fun and harder. Primary school children should not be expected to learn this, when I didn't even learn it at GCSE. I have never needed to know these things, and it is a pointless waste of time for the pupils and teachers alike.
