English teacher, eh? Reading Daniel's stuff must be exquisitely painful for you.
I teach English as a foreign language, just to clarify what kind of English teacher I am.
When I grade writing, I use these criteria:
Task Achievement. Did you answer the question? Did you use the appropriate register ( style of language, e.g. formal/ informal/ neutral)? Do you demonstrate coherence and cohesion?
My mark for Daniel: needs development. Too many unanswered questions and a confrontational, mocking tone, with an occasional use of inappropriate use of metaphor ( "I will take your argument outside and bludgeon it to death" sticks out).
Language: Grammar, spelling and vocabulary.
My mark for Daniel: Needs development. To be fair, his grammar and spelling are fine. However, his insistence on trying to redefine words to suit his arguments displays a rather cavalier attitude to vocabulary. If everyone was to do the same, meaningful communication would be all but impossible.
Organisation: Punctuation, capitalisation, sentence length, paragraphing.
My mark for Daniel: Weak for level/ fail. Incorrect capitalisation, highlighting and excessive punctuation are scattered like confetti over his posts. This adds confusion rather than added meaning or emphasis.
I have no doubt that Daniel will write this off as 'colour commentary'. ( I am expecting a response to this, as he has so far avoided my more pertinent posts like the plague.)
I have no problem with this at all: if Daniel won't engage seriously, then neither will I. No harm in a bit of fun now and then!
