The study also sought to examine the frequency ofthe errors and what can be done to improve the teaching of L2 （English） writing in the Senior High School. Thestudy used a corpus of essay writings of 150 second year students. The schools and the participants werepurposively selected. The data were analyzed using the content analysis approach. The study identified that thelexical errors in the students＇ writing were due to homophone problems and semantic lexical errors. Thegrammatical errors identified were agreement errors, tense errors, singular-plural （number） errors, prepositionalerrors, and article errors. The study also found that the most frequently committed grammatical error was tenseerrors followed by agreement errors. The implications of these findings to the teaching of English writing are thatteachers where possible should have understanding of both the L1 and L2 of the students and teachers shouldexplicitly teach for transfer, have adequate knowledge of how to identify students＇ writing errors, and use effectiveteaching strategies to improve students＇ English writing. Additionally, teachers should serve as models of usingappropriate English for students to emulate and also create a conducive classroom environment for students toparticipate in class activities. Lastly, teachers should create more opportunities for students to write.展开更多

The study aims at investigating some second language learners＇ meta-linguistic ability in solving multidimensional grammatical problems. The subjects of the present study were 40 Egyptian students who were in their fourth year of academic study in the Department of English and Literature, Faculty of Arts, Menufia University, Egypt. The instrument of this study consisted of pre-test, post-test and individual interviews. Two tasks were used： （1） ＂Sentence Completion＂ task; and （2） ＂Error Recognition and Correction＂ task. Finally, students were interviewed to explain and comment on their performance in the previous tasks. The data were analyzed both quantitatively and qualitatively. Results were obtained and conclusions were made.展开更多

The development of GP involves various aspects, including design of genetic operators, evolutionary controls and implementations of heuristic strategy, evaluations and other mechanisms. When designing genetic operators, it is necessary to consider the possible limitations of encoding methods of individuals. And when selecting evolutionary control strategies, it is also necessary to balance search efficiency and diversity based on representation characteristics as well as the problem itself. More importantly, all of these matters, among others, have to be implemented through tedious coding work. Therefore, GP development is both complex and time-consuming. To overcome some of these difficulties that hinder the enhancement of GP development efficiency, we explore the feasibility of mutual assistance among GP variants, and then propose a rapid GP prototyping development method based on πGrammatical Evolution (πGE). It is demonstrated through regression analysis experiments that not only is this method beneficial for the GP developers to get rid of some tedious implementations, but also enables them to concentrate on the essence of the referred problem, such as individual representation, decoding means and evaluation. Additionally, it provides new insights into the roles of individual delineations in phenotypes and semantic research of individuals.展开更多

Although a number of annotated corpora have been established to facilitate data-driven grammatical error detection and correction approaches, they are still limited in terms of quantity and coverage because human annotation is labor-intensive, time-consuming, and expensive. In this work, we propose to utilize unlabeled data to train neural network based grammatical error detection models. The basic idea is to cast error detection as a binary classification problem and derive positive and negative training examples from unlabeled data. We introduce an attention-based neural network to capture long-distance dependencies that influence the word being detected. Experiments show that the proposed approach significantly outperforms SVM and convolutional networks with fixed-size context window.展开更多

The statistical analysis showed that the cross-linguistic effects of L2 on L1 were significant although such impact was bidirectional. There were significantly more grammar errors and longer retrieval time committed by the bilingual group which implied negative L2 transfer to L1. Meanwhile, L2 also showed a positive influence on lexical diversity as there was no decline in lexical richness but an increase in lexical variations, and this indicated that L2-induced patterns did not replace or deteriorate L1 but instead added additional options to L1 expressions. This phenomenon can be characterized as the addition of new concepts and linguistic options to the already-existing L1 and conceptual repertoire. Specifically, meta-linguistic competence was enhanced. This research supports the theory of interference on L1 by the use of L2 （negative transfer）, but it could also be enhanced by L2 （positive transfer）.展开更多
