Moreover, previous studies mainly focus on comparing the effectiveness of native and non-native language teachers by exploring learners＇ and teachers＇ perceptions of native and non-native language teachers. Since recruitment criteria are theoretically unjustified and the results of previous studies are subjective and inconclusive, this study aims at making a case in the opposite direction. That is, the researchers argue that there should be： （1） a shift away from recruiting language teachers on the basis of their speaking fluency and native language background towards hiring language teachers on the basis of their professional performance in the language classroom; （2） a shift away from exploring learners＇ and teachers＇ perceptions of native and non-native teachers towards studying the effect of teachers＇ native language on learners＇ proficiency, accuracy, fluency, and achievement. To pave the way for these shifts, this study first reviews the theoretical perspectives and empirical findings concerning effective language teachers and then draws conclusions and implications which help interested stakeholders, i.e., supervisors, make informed decisions when they recruit language teachers.展开更多

In this paper, the author details the three aspects substation construction management of the project, namely the concept of substation engineering, project management and construction safety, through these three aspects, the author analyzes the construction project management substation existing problems, To solve these problems and issues proposed some measures and construction process that need attention. It launched separately from the design, schedule, quality and other aspects of security and research, and in the course of the study stressed the importance of coordination between elements of construction and construction sectors as well as cooperation between the construction, explains the importance of the project cost control.展开更多

This paper not only improved the tendering and bidding stage method of cost control in construction project in our country, and improves the method system of engineering cost control.展开更多
