A class of variational difference schemes is constructed by the finite element method. Uniform convergence about small parameter is proved under a weaker smooth condition with respect to the coefficients of the equation. The schemes studied in refs. [1], [3], [4] and [51 belong to the cllass.展开更多

The research finds that(1) teachers in different class types prefer to adopt evaluative feedback and use more positive feedback.(2) the proportion of each feedback is different in listening and speaking, reading and writing class. The implications are that English teachers in senior high school should adopt different feedback flexibly and consider what kind of feedback is more likely elicit the students' output in different class types.展开更多

The EAP course could not only enhance the communication skills of the international students, but also improve their knowledge of English grammar, vocabulary, spelling, sentence structure and composition skills. The purpose of this paper is to analyze the useful teaching method teacher used in class, and help different students improving their English skills.展开更多

This study investigates how teacher’s in-class feedback based on individual learner differencesaffects EFL students’correction of writings and students’attitude towards teacher’s in-class feedback based on their individualdifference, as well as the factors that influence teachers’feedback among three EFL students and an in-service English teacher byemploying interviews, classroom observations. The findings indicate that students pay more attention to their errors in their writingsand students hold a positive attitude towards teacher’s in-class feedback based on their individual differences, students’aptitudeand personality mostly affect teacher’s in-class feedback.展开更多
