Last year, a report by a mittee of education experts said that a lot of American students cannot write well. The report noted the concerns of business leaders and teachers. The experts said that more students should have to pass a writing test before they can finish high school. They pointed out that major college entrance tests are changing now to include a writing part.
Educators know that teaching students to write well is not easy. One problem is the amount of time needed to read through large amounts of work. So some panies have developed puter programs. These can grade student writing much more quickly than a person can. Writing tests can also cost less to carry out by puter than paper-and-pencil. These puter systems are known as e-readers. They use artificial (人工的) intelligence to think in a way like teachers. In the state of Indiana, puter grading of a statewide writing test began with a test of the system itself. For two years, both a puter and humans graded the student writing. Officials say there was almost no difference between the puter grades and those given by the human readers.
The entrance test monly used by business schools, the GMAT, already uses e-readers. The GRE and TOEFL tests might start; officials are deciding. The GRE is the Graduate Record Examination. TOEFL is the Test of English as a Foreign Language.
Systems are also being used to grade writing in college classes. The puters read a few hundred examples of student writing already graded by humans. Then the systems pare new writings against those already examined.
How do teachers feel all about this? Many say machines can never do the job as well as people can. A puter can find spelling and grammar mistakes. But these teachers say it can never really understand what a writer is trying to say. Critics say a program cannot follow a thought or judge humor or understand a beautifully expressed idea.
But inventors of the programs say puter grading guarantees that each piece of writing is graded in the same way. They also say the systems are meant to judge knowledge more than creativity.
