This is the first a few lines of a passege written about child education.
Ideally, competence and self-confidence will have developed from a child's earliest days through interaction between the child and the environment. The child affects his environment and in turn the environment affects him; ...
I don't know what "will have developed" means. If it's just "develop", not "will have developed", what is the difference in meaning? I think I'm missing something very important.
I really appreciate your reply.
The piece is presumably written about some later stage in a child's education. "By the time a child first goes to school, s/he will have developed..." (The context may not be as explicit as that. Maybe it's in a conference called 'What can primary school teachers expect?' The keynote speaker, knowing that everyone has this context in mind, may just start 'A child will have developed....'). Choosing appropriate tenses often depends on a context that extends to things other than just the words involved in the text or speech.
