The statistical results show that grammar testing methods can greatly improve the annotation consistency of slight-pause marks boundary recognition. The consistency during the second time is 0.030 3 higher than during the first, which will help guarantee the consistency of large-scale corpus annotation and improve the quality of corpus annotation.展开更多

Such errors even still remain after four-year English learning at university. Such problem has troubled many teachers teaching English Grammar. Therefore, the paper attempts to study the ways of improving English majors＇ grammatical competence. It is concluded that reform of grammar test should be carried out to guide grammar teaching and learning, error analysis should be conducted to decide what to teach, and an output-oriented approach should be employed to meet the requirements of leamers＇ future profession.展开更多

The results of the two types of testing items and data have been analyzed to reveal that testing grammar and usage in the form of completion items in context by using multiple-choice techniques shows its advantages over completion forms in separate sentences by using multiple-choice techniques.展开更多
