‘Everyone thinks that I just need to know a few words and sing some songs to teach English to the kids’: primary school English language teachers struggled for their professional legitimacy     

Chinh Duc Nguyen 《Teacher Development》2019,23(2):174-191

Language teachers’ struggles for professional legitimacy have emerged as an area of interest in the field of language teaching research. Grounded in Wenger’s concept of ‘trajectories of learning’, the current study explored the fight for legitimate status of two primary school English language teachers in Vietnam. Data for this article were collected through life-history interviews in which the two participating teachers were encouraged to tell stories about the early days of their teaching careers. The findings of the study reveal that the participants struggled for professional legitimacy during the early stage of their teaching careers. Beyond the school setting, the two teachers encountered negative attitudes towards their teaching profession as teaching languages to young learners was not highly valued in society. Based on the findings, the study pointed to the issue of power relations which, although regarded as a barrier to teachers’ professional legitimacy, is not adequately addressed in the concept of ‘trajectories of learning’. The study also revealed some implications for legitimising language teachers’ professional status.  相似文献   

Science Career-Related Possible Selves of Adolescent Girls: A Longitudinal Study     

Becky Wai-Ling Packard  Dam Nguyen 《Journal of Career Development》2003,29(4):251-263

This paper uses a possible selves theoretical framework to examine whether and how adolescent girls' images of themselves as future scientists change during their transition from high school to college. Forty-one female high school graduates from diverse ethnic and socioeconomic backgrounds, who had enrolled in an intensive math and science program while in high school, participated in interviews focused on their perceptions of factors that influenced their career plans over time. Participants suggested that career-related internships and intensive academic programs, especially those that yielded important mentoring relationships, were contexts in which they negotiated career-related possible selves and subsequent career plans.  相似文献   

Sustainable assessment for lifelong learning     

Tham T.H. Nguyen  Melanie Walker 《Assessment & Evaluation in Higher Education》2016,41(1):97-111

This paper explores the alignment of assessment practices in universities and lifelong learning as a key process and outcome for expansive student development. It outlines Boud’s approach to assessment, operationalises this to analyse practices in two contrasting national contexts: the sociology departments of the Midlands University in the UK and Nam Du University in Vietnam, and reframes this framework as a guide to improving practices and better-supporting lifelong learning. The paper thus contributes to recent debates about sustainable assessment and how to change assessment to better support students for lifelong learning in different countries. The findings suggest that although more elements were found at Midlands University than Nam Du University, assessment in both cases was an imperfect realisation of this framework. Nonetheless, the paper argues that the framework can offer guidance for changes to align assessment practices with lifelong learning, but to do this it should be adapted to the education context and also expanded to include explicit social commitments to others for expansive lifelong learning.  相似文献   

Feminist Rhetoric in Cyberspace: The Ethos of Feminist Usenet Newsgroups     

Christine Ann Nguyen Fredrick 《The Information Society》1999,15(3):187-197

Users of the Internet are stripped of voice inflections, body language, and other common cues of conversation-only their words are left. Some claim that the lack of these social cues and the lack of hierarchy in the structure of the Internet provide the potential for equality in cyberspace. Many others have shown, though, that the issues of power in cyberspace are similar to the issues of power in physical space. This article examines an intersection of feminism and cyberspace in the ethos of online discussion. It is a rhetorical analysis of two popular feminist newsgroups, alt.feminism and soc.feminism. Do these newsgroups create a feminist and inclusive space online? What are the rhetorical strategies that make an online space more or less inclusive of women? Usenet newsgroups reveal the rhetorical power of these bare words. Although no formal means of discrimination is built into Usenet newsgroup discussions, discrimination does occur through the subtle and not so subtle use of language. This article looks at how various characteristics of language are used on the two newsgroups. Though the ethos on such discussion forums is dynamic, the analysis reveals examples of how sarcastic questioning, strong assertions, accusatory disagreements, and sexistcomments can create a hostile and noninclusive ethos.  相似文献   

Dissociation of conditioned appetitive and consummatory sexual behavior: Satiation and extinction tests     

Stewart Hilliard  Michael Domjan  Michael Nguyen  Brian Cusato 《Learning & behavior》1998,26(1):20-33

Sexual responses were conditioned in male Japanese quail using the opportunity to copulate with a female as the unconditioned stimulus (US). The conditioned stimulus (CS) was a 3-D object made of a taxidermically prepared female quail head mounted on a terry-cloth body. Both appetitive conditioned responses (approach and proximity to the CS) and consummatory conditioned responses (mount and cloacal contact directed toward the CS) developed when 2-min presentations of the CS were followed immediately by the US, but not when the CS and US were separated by trace intervals of 10 or 20 min (Experiment 1). Postconditioning sexual satiation suppressed conditioned cloacal contact responses more than conditioned approach to the CS (Experiment 2), and “acute” extinction suppressed both conditioned mounting and conditioned cloacal contact responses more than conditioned approach to the CS (Experiment 3). These results demonstrate a functional dissociation between conditioned appetitive and consummatory responses and imply that the motivational and/or associative mechanisms underlying the two types of behavior are distinct.  相似文献   

Thermal mixing of two miscible fluids in a T-shaped microchannel     

Xu B  Wong TN  Nguyen NT  Che Z  Chai JC 《Biomicrofluidics》2010,4(4):44102

In this paper, thermal mixing characteristics of two miscible fluids in a T-shaped microchannel are investigated theoretically, experimentally, and numerically. Thermal mixing processes in a T-shaped microchannel are divided into two zones, consisting of a T-junction and a mixing channel. An analytical two-dimensional model was first built to describe the heat transfer processes in the mixing channel. In the experiments, de-ionized water was employed as the working fluid. Laser induced fluorescence method was used to measure the fluid temperature field in the microchannel. Different combinations of flow rate ratios were studied to investigate the thermal mixing characteristics in the microchannel. At the T-junction, thermal diffusion is found to be dominant in this area due to the striation in the temperature contours. In the mixing channel, heat transfer processes are found to be controlled by thermal diffusion and convection. Measured temperature profiles at the T-junction and mixing channel are compared with analytical model and numerical simulation, respectively.  相似文献   

Micro-optofluidic Lenses: A review   总被引：2，自引：0，他引：2  

Nam-Trung Nguyen 《Biomicrofluidics》2010,4(3)

This review presents a systematic perspective on the development of micro-optofluidic lenses. The progress on the development of micro-optofluidic lenses are illustrated by example from recent literature. The advantage of micro-optofluidic lenses over solid lens systems is their tunability without the use of large actuators such as servo motors. Depending on the relative orientation of light path and the substrate surface, micro-optofluidic lenses can be categorized as in-plane or out-of-plane lenses. However, this review will focus on the tunability of the lenses and categorizes them according to the concept of tunability. Micro-optofluidic lenses can be either tuned by the liquid in use or by the shape of the lens. Micro-optofluidic lenses with tunable shape are categorized according to the actuation schemes. Typical parameters of micro-optofluidic lenses reported recently are compared and discussed. Finally, perspectives are given for future works in this field.  相似文献   

Helpful components involved in the cognitive-experiential model of dream work     

Hsiu-Lan Shelley Tien  Shuh-Chi Chen  Chia-Huei Lin 《Asia Pacific Education Review》2009,10(4):547-559

The purpose of the study was to examine the helpful components involved in the Hill’s cognitive-experiential dream work model. Participants were 27 volunteer clients from colleges and universities in northern and central parts of Taiwan. Each of the clients received 1–2 sessions of dream interpretations. The cognitive-experiential dream work model was applied to these clients by three therapists. The processes of the dream work were audio-taped and transcribed verbatim. The transcribed data, which included a total of 38 sessions for the 27 clients, were analyzed by the Consensus Qualitative Research (CQR) approach to examine the helpful components of the dream work. The results indicated that the general and typical helpful components involved in the process of dream interpretation included four domains: waking-life association, parts of self exploration, gaining insight, and action ideas.  相似文献   

Relations between goals,self‐efficacy,critical thinking and deep processing strategies: a path analysis     

Huy Phuong Phan 《教育心理学》2009,29(7):777-799

Research exploring students’ academic learning has recently amalgamated different motivational theories within one conceptual framework. The inclusion of achievement goals, self‐efficacy, deep processing and critical thinking has been cited in a number of studies. This article discusses two empirical studies that examined these four theoretical orientations from both cross‐sectional (N = 279 participants) and longitudinal (N = 264 participants) perspectives. In particular, achievement goals are hypothesised to exert direct and indirect effects on academic performance via self‐efficacy, study processing strategies and critical thinking. Path analysis was used to test and analyse the hypothesised conceptual models. Results from SPSS 16 and LISREL 8.72 provided good support for the hypothesised structural relationships. Students’ academic performance outcomes, for example, are determined directly by deep processing and work‐avoidance goals. Results from Study 2 indicate mastery goals and self‐efficacy, mastery goals and critical thinking and deep processing and critical thinking operate in a reciprocal manner. In general, the evidence established from both studies contributes theoretically and methodologically.  相似文献   

Towards an understanding of dynamics among teachers,teacher leaders,and administrators in a teacher-led school reform     

Tuan D. Nguyen  Seth Hunter 《Journal of Educational Change》2018,19(4):539-565

A substantial amount of professional development and implementation has moved towards teachers and teacher leaders in recent years. Previous works have examined how teachers, teacher leaders, or administrators perceive teacher leadership in school reforms, but few have advanced all three perspectives simultaneously. Drawing upon over 200 interviews, we examine how leadership is distributed and the tensions and dynamics arising among these three groups in a teacher-led school reform. Two main themes emerged from our analysis: minimizing conflicts with teachers was important to teacher leaders, and the distribution of leadership between administrators and teacher leaders changed the status and normative roles of teacher leaders.  相似文献
