An epidemic (流行病) of the use of street-culture language broke out in some English exams, according to examiners.
A report said there were “a surprising number of small mistakes” in standard (标准) English. It asked teachers that they should prevent pupils from using street language and text style, adding, “Most answers require formal expression of language.”
“Many concerns were expressed by examiners about basic errors, often appearing in the work of clearly able students,” the report continued.
It added that the use of street and text language “appeared with surprisingly regularity in the work of students who clearly desired a higher grade”.
“Most answers require formal expression but even when an informal style is appropriate--students should know the examination context and, in particular, should not use street language and text style.” it said.
There is rising concern about pupils’ writing skills, especially among boys. National test results for 11-year-old boys’ writing standards had fallen this year. Only 55 percent reached the level expected of an 1l-year-old by the time they left primary school, the results showed.
Many educationalists are now arguing that teachers should also think of ways of improving writing standards.
The report said spelling was “in general inconsistent(不一致)” and “variety of vocabulary and of sentence structure is often limited”. It went on, “Punctuation (标点符号) errors continue to be widespread.”
However, it added, “Some examiners felt that this year they had met an improvement in the whole structure of students' writing.”
