When I was in high school 5-6 years ago I had classmates who wrote papers in Ebonics/AAVE. I, being an honor student had to help grade papers and was consistently told to mark Ebonicsisms wrong. For standard American and Commonwealth English the mistakes Ebonics speakers make are dropping verbs when describing the subject, i.e. 'she hot and smokin' and constant use of contractions as well as improper verbal conjugations.

It's my opinion AAVE is not acceptable English, as that is how I was raised. It makes people sound uneducated and illiterate and oftentimes my classmates who spoke it and wrote in it were far behind the rest of the class. Some of them had grammar school level reading levels and constantly complained when people used 'big words'. They would also get combative when I explained the errors of their papers and why they ended up with D's or F's on their papers, claiming they didn't make errors because they talk that way in other teachers classes and never get corrected.

Some may argue we should be more accommodating towards people who speak Ebonics which I would agree with only if they actually didn't make serious grammatical errors like 'I is a basketball player' and such.

It's often the same case for Chinese speakers in the South and Central part of China who have local languages they speak which influence their Mandarin and English language accents. Like for instance my buddy from the Henan province cannot say the word 'five' he has to say 'feeve' due to the Henan dialect of Mandarin he learned. However I have patience with him and his speaking of English because he doesn't get combative or angry when I correct his pronunciation or grammatical errors.
