The shift of emphasis away from written to oral skills has stimulated an incipient concern in second language research to investigate ways of helping second and foreign language learners achieve higher degrees of oral proficiency. Priority solely taken over accuracy, complexity, or fluency of speech might be justifiable with regard to the context in which learning takes place.  Accuracy and com...

In this study, we improve grammatical error detection by learning word embeddings that consider grammaticality and error patterns. Most existing algorithms for learning word embeddings usually model only the syntactic context of words so that classifiers treat erroneous and correct words as similar inputs. We address the problem of contextual information by considering learner errors. Specifica...

Grammatical error correction (GEC) is the task of detecting and correcting grammatical errors in texts written by second language learners. The statistical machine translation (SMT) approach to GEC, in which sentences written by second language learners are translated to grammatically correct sentences, has achieved state-of-the-art accuracy. However, the SMT approach is unable to utilize globa...

Among the major issues raised by classroom SLA researchers is the debate on the degree to which teacher’s or learner’s attention should be directed to linguistic features. However, one of the relevant variables in corrective feedback studies which seem to be less operationalized is the differential impact of different types of feedback on the accuracy of the oral performance of the participants...

homogenous charge compression ignition (hcci) engines hold promise of high fuel efficiency and low emission levels for future green vehicles. but in contrast to gasoline and diesel engines, hcci engines suffer from lack of having direct means to initiate combustion. a combustion timing controller with robust tracking performance is the key requirement to leverage hcci application in production ...

This paper describes accuracy measurement method for high resolution miniature robot manipulators. The robot itself, measuring method and the results are presented. Parallel kinematic robot structures have by now seen as the most promising, due to their simpler and stiffer structure and easier miniaturisation. A robot using the direct drive method and direct high resolution feedback has been st...

Promoting communicative interactions, while simultaneously drawing students’ attention to language form, is considered as a potentially significant area of research in second language acquisition. This study focuses on the effect of transcribing task, as an autonomous noticing activity, on intermediate and advanced EFL learners' grammatical accuracy. The study was conducted in two advanced and ...

when studying russian morphology, one can distinguish two categories. these categories are “grammatical” and “lexico-grammatical”. grammatical categories can be specified through a series of grammatical features of words. considering different criteria, russian grammarians and linguists divide grammatical categories of their language into different types. in determining lexico-grammatical types...

Teaching grammar has always been a problematic area of language teaching.  While teachers spend a great deal of time and energy to teach, the students are not eager to learn as they find it a real chore. This study compared two kinds of activities for teaching grammar: games and traditional exercises. It sought to discover the effect of games on the students’ grammatical accuracy. For this purp...
