The researchers engaged in a qualitative analysis (using journaling and focus group methodology) of the communicative behaviors of Hispanic students with White institutional members at a medium-sized, Southwest HSI. Utilizing Co-Cultural Theory and Elaborative Coding analysis, the authors mapped how Hispanic students narrated their co-cultural communication and reasoning (i.e., why they engage in one strategy rather than another). The findings show that, although Hispanic students used almost all co-cultural strategies, their responses were clustered primarily around assimilationist strategies – indicating that they engage in a high degree of self-monitoring and self-censorship when interacting with White institutional members in an HSI. These results suggest that even when Hispanic students constitute a large or majority part of the institution’s population, they still feel the need to engage in behaviors that navigate White norms. The study concludes by examining the findings for co-cultural theorizing as well as providing insights for instructors who wish to engage in inclusive teaching practices.  相似文献

The purpose of this study is to examine the relationship between perceived ageism and depression in later life and to clarify the mechanism underlying this relationship by examining the mediating effects of self-perception of aging and purpose in life. The Health and Retirement Study surveys were used for this secondary analysis of data. The sample included 3,991 older adults, and structural equation modeling (SEM) analyses using structural regression models were conducted. SEM analyses revealed that full mediation effects of self-perception of aging and purpose in life exist. Older adults who perceive ageism are likely to have negative self-perception of aging, and this negative view of their own aging is likely to decrease purpose in life and increase depressive symptoms. The results of this study imply that more efforts and resources are necessary to reduce ageism and its negative effect on depression among older adults. Additionally, the current study suggests the necessity of anti-ageism policies and social services. Increasing positive self-perception of aging, purpose in life, and resilience could be the key to a better quality of life for older adults.  相似文献

The dominant role of English as the global language of science entails a requirement for science teachers to equip their non-native English-speaking students with receptive and productive language skills for communication in scientific contexts. Although science courses with English elements are part of some schools’ bilingual programmes, they are usually not available to a wider student audience, but are restricted to high achieving or highly motivated students. The present study was to test whether a newly developed biology content and language integrated learning (CLIL) unit could also benefit standard ninth grade classes. The learning gains and motivation of bilingually inexperienced students were compared to those of a preselected group and a comparison group that had been taught solely in their native language. All participating classes achieved similar gains in content knowledge, and the standard students rated their motivation for bilingual science lessons as positive, albeit not as high as the preselected group. We thus provide evidence against concerns that teaching non-selected students bilingually might lead to deficits in content knowledge acquisition. Following this, we conclude that scientific English should be a part of standard science lessons regardless of specific school programmes.  相似文献

Teacher–student discourse continues to be teacher-centred even though researchers and reform documents have recommended changes toward increased levels of student-centred discourse. In science education this situation is paralleled by effort to make scientific inquiry more student-centred. The purpose of this study was to investigate how discourse forms changed over time in a classroom where the regular teacher and his students were scaffolded in the transitioning to student-centred scientific inquiry. Video-recordings were collected at intervals over one academic year. Three prominent forms of discourse were identified: two teacher-authoritative forms and one more interactive, dialogic form. As the lessons increasingly turned into student-centred scientific inquiry, a shift to the dialogic discourse form was found. Co-teaching provided for (a) guidance towards an organisation of events in the classroom that included regular teacher–student dialogue (b) modelling of the more dialogic form of discourse.  相似文献

本文从师生互动的维度解析了中国留学生在美国大学中的学业压力因素.四种因素构成了中国学生和美国教授互动的主要压力因素:语言功力不足、缺少对学业的自治和自主引领、言语表达的被动性、交流模式的非直接性.中国学生的压力是中关两种文化模式和教育模式碰撞合力作用的结果.这为反思中国教育的问题提供了有效切入点.本文从英语语言教育和转变人才培养观念两个方面为中国教育提出了相应的建议.并指出中国学生应进行"深层结构性社会文化转化",充分适应美国大学的学术文化,与美国教授形成良性互动,最终减缓跨文化所带来的压力.  相似文献
