语法翻译法和交际法在精读课中结合应用的实证分析     

周玉萍  吕卉 《通化师范学院学报》2011,32(11):91-92,113

高等院校英语专业教学的最终目标是培养学生运用目标语言进行交际的能力,然而,当前英语专业学生的交际能力却不容乐观。如何在精读课中提高学生的交际能力已成为外语教学界的一个热门话题,也是摆在高校英语教师面前亟待解决的重要课题。针对学生的特点和教学特点,在实验的基础上提出了一种融合语法翻译教学法和交际教学法各自优势的教学法,以达到在精读课中提高英语专业学生交际能力的目的。  相似文献

Parents’ PTSD symptoms and child abuse potential during the perinatal period: Direct associations and mediation via relationship conflict     

《Child abuse & neglect》2019

BackgroundPosttraumatic stress disorder (PTSD) symptoms are associated with parental aggression towards children, but little is known about the relation between parents’ PTSD symptoms and their risk for perpetrating child physical abuse during the early parenting years, when the potential for prevention of abuse may be highest.ObjectiveTo examine direct associations between mothers’ and fathers’ PTSD symptoms and child abuse potential, as well as indirect effects through couple relationship adjustment (i.e., conflict and love) in a high-risk sample of parents during the perinatal period, most of whom were first-time parents.Participants and settingFrom March 2013 to August 2016, data were collected from 150 expecting or new parental dyads in which the mother was participating in a home visiting program.MethodsData were analyzed using the Actor-Partner Interdependence Mediation Model.ResultsFor mothers and fathers, there were direct associations between PTSD symptom severity and child abuse potential (βs = .51, ps <.001), and this association for fathers was stronger at higher levels of mothers’ PTSD symptoms (β = .15, p = .03). In addition, parents’ own and their partners’ PTSD symptoms were each indirectly associated with parents’ own child abuse potential through parents’ report of interparental conflict (standardized indirect effects = .052–.069, ps = .004) but not love.ConclusionsAddressing parents’ PTSD symptoms and relationship conflict during the perinatal period using both systemic and developmental perspectives may uniquely serve to decrease the risk of child physical abuse and its myriad adverse consequences.  相似文献

Travels in hyper-diversity: Multiculturalism and the contextual assessment of acculturation     

《Int J Intercult Relat》2013,37(6):686-699

We argue that current acculturation research offers an incomplete picture of the psychological changes taking place in contemporary multicultural societies. Several characteristics of the Canadian multicultural context highlight the limitations in current acculturation research: namely, themes of hyper-diversity, hybridity, dimensionality and the importance of local context. Canada is a case in point, but these themes are generalizable to other contemporary multicultural contexts. To address the limitations of the traditional psychological acculturation paradigm, we propose an innovative research approach to study acculturation: the Cultural Day Reconstruction Method (C-DRM). We report on two studies that implemented this diary method, to demonstrate that this research tool (1) addresses theoretical critiques of current acculturation research and (2) captures some of the complexity of acculturation in contemporary multicultural contexts. The C-DRM was constructed in response to the local research environment but we hope it will become part of a new generation of tools for the contextual assessment of acculturation.  相似文献
