I've heard before that in the US children learn capital letters before learning lower case letters. Several American TV programmes seem to bear this out, eg 'Super Why' which shows the alphabet in capitals and words in capitals.
So, do American children at school generally learn to read and write using capital letters? Do they learn to write their names completely in capitals? And what is the rationale for this? IMO learning to read using (mostly) lower case letters makes far more sense, because most of the text in books and in other places around us is lower case. Plus, words that are in lower case are easier to recognise by shape.
My dds are very big fans of 'Super Why', and dd2 (3) has learnt some letters through watching the programme, but she's learning capitals, and there is more emphasis on the letter names than the letter sounds in the programme, so I think it could be somewhat confusing for her.
