I agree with superval. Grammar, spelling, punctuation and sentence construction in English have all been neglected in schools over here.
Creativity and expressing one's feelings have been encouraged, which is great, but it has been at the expense of the "nuts and bolts" of the language. At times, it has resulted in a lack of clarity in meaning and understanding and the need to re-read a sentence several times in order to divine exactly what the writer is trying to convey.
You need to know, to understand and to apply the "rules" of a language before you can go on to break those "rules" in order to increase the impact of what you are writing.
The difference between everyday spoken English and more formal written English has been underplayed in schools, not to say ignored.
I love the English language - its vast vocabulary, its many different words with similar but slightly different meanings, its pliability, its regional and national variations (some expressive words used in Scotland but rarely elsewhere, for example), its ability to absorb from other languages, the way it evolves and develops and so on - but I do wish that some of its more formal aspects were better understood and applied.
Good grief, I sound like an old fogey! Perhaps that's my role from now on - grumpy old man!
