This study examined certain effects of seven student pre‐enrollment characteristics and three student‐institutional characteristics on retention status. Path analysis of these longitudinal data was unable to compare favorably with other studies using similar determinants. Certain practical implications of the study also are presented, emphasizing the burden of evidence that suggests that entering student characteristics cannot be used alone to explain the retention decision, that retention programs should be strategically rather than generically focused, and that program holding power may be related to student career consciousness and goal specificity.  相似文献

The purpose of this article is to demonstrate constraining the nominal response model in Mplus software to calibrate data under the partial credit model (PCM) and generalized partial credit model (GPCM). Currently, many researchers are uncertain if the PCM and GPCM can be estimated within Mplus. Through model constraint commands in Mplus, we demonstrate that both models can be estimated in recent versions of this software. We present an example of this approach with data from 522 respondents on a subset of items from the Math Self-Efficacy Scale (Betz & Hackett, 1983). It is demonstrated that the presented model code is a viable way of estimating the models in Mplus.  相似文献

Research Findings: This study investigated how the Strengthening Families through Early Care and Education initiative in Illinois (SFI) influenced change in 4 child care programs. Findings indicate that SFI influenced quality improvements through 4 primary pathways: (a) Learning Networks, (b) the quality of training, (c) the engagement of program directors, and (e) the organizational climate at programs. SFI's multilevel model of implementation was key to its effectiveness. Two barriers to improving family partnership practices were identified: lack of cultural competence and a negative organizational climate. Practice or Policy: First, quality improvement and professional development efforts are likely to be more effective in promoting real change when they target multiple levels of the context in and around child care programs. SFI's multilevel implementation approach is a model. Second, quality improvement efforts in the area of family engagement may be more effective when specific attention is given to strategies for creating a supportive organizational climate and collegial relationships among staff. Relationships within programs set the tone for relationships with families. Third, cultural competence requires increased attention to efforts to improve the quality of family partnership practices. A focus on organizational cultural competence may provide the workplace environment necessary to support culturally competent practice among program staff.  相似文献

This article looks closely at the talk of two pre-service teachers over time to examine how they used language as a way of rehearsing their evolving agency as literacy educators. Drawing on critical sociocultural theory, I use Agency Tracing to highlight how pre-service teachers’ agentic actions are not isolated phenomena but ones developed and planned with others in language. Through rehearsals, they considered possible options and outcomes of actions before taking risks, therefore bolstering their confidence to act and resist individual and institutional Discourses of literacy. Analysis reveals that because pre-service teachers rehearse agency over time via language, such agency can be developed in teacher education coursework and field experiences. Findings indicate four recommendations to foster agency: rehearsals over time, dissonance to the point of frustration, observations and approximations in field experiences, and interactional spaces for critical reflection.  相似文献

Contemporary commentary notes that students are frequently ahead of their teachers in their ability to manipulate and be creative with the internet, digital programs, and mobile technology. In this context it is important to ask, ‘What knowledge do teachers need to teach in the contemporary context where texts are elaborately multimodal, constructed not just of print but of image, sound, and movement?’ This paper proposes some signposts to assist teachers with navigating in this environment. Using teachers’ and researchers’ reflections on practices in a diverse range of settings, both primary and secondary, the analysis explicates the challenges that teachers face in this multimodal context and elucidates some ways they can effectively operate within it. In particular, it argues that it is teachers’ expertise as analysts and critics of texts that needs to guide their planning and teaching in this ‘new’ text world.  相似文献

Conceptualizations of teacher knowledge have shifted to focusing on the role of experiential rather than theoretical knowledge. There are different approaches to this, but the idea of an image that guides practice is widespread. One approach to images that has not been frequently investigated in studies of second language teachers is through sociocultural theory, specifically in the contribution of activity theory known as orienting activity. In this view, images mediate teaching actions by linking theoretical knowledge and practical experience. This article will use orienting activity to examine the role that images play in an English as a second language teacher’s personal practical knowledge by drawing on classroom observations, informal discussions, simulated recall interviews and documentary evidence collected over a nine month period. Analysis of the data shows that several key images mediated the teacher’s classroom actions. These emerged in the observations and in the teacher’s commentary on planned and spontaneous, routine and novel and successful and unsuccessful activities. The images appeared to have developed through both tacit knowledge associated with practical experience and theoretical knowledge associated with research and theory. This demonstrates the usefulness of orienting activity as a theoretical framework for exploring classroom practices and teacher development through the links it can make between theory and practice.  相似文献

This article explores the crucial moments of scientists’ research activities when they decide to shift to a radical new domain or to perpetuate a project. We introduce what we have called the “respiration model” which describes and analyses key cognitive components which occur in this complex process. Respiration either privileges epistemic expectations which are rooted in socio-cognitive metrics of “concentration” or in a functionality-multiple horizon context which we refer to as “extension”. The respiration model accords particular attention to the elements curiosity and synergy in science.  相似文献

The methodology of protecting the European stained glass windows against environmental risk (e.g. meteorological factors, air pollution, microorganisms) by means of an external glazing is not new. In spite of many scientific studies carried out in the last 20 years, some questions were still up for discussion. The European VIDRIO (2002–2005) project gave an answer to these questions. The research carried out by the different project partners established a new multidisciplinary approach aimed at evaluating the efficiency of the protective glazing systems and their effects on stained glass windows conservation, and finally at assessing the most appropriate strategy to preserve stained glass windows. Scientific results showed that the so-called isothermal glazing (i.e. ventilation by the air coming from the inside of the building) protected efficiently the ancient stained glass window from environmental attack (i.e. rain, pollutants, condensation, thermal shocks) with very limited secondary effects. The scientific research highlighted that its efficiency was strongly related to the technical design of the protective system. In particular, the ventilation and the size of the interspace had to be carefully considered. The research developed within the VIDRIO project was turned into general recommendations to the owners and practitioners on the best practice for the stained glass windows future conservation.  相似文献

Abstract

The vast majority of social scientific studies of sport have been secular in nature and/or have tended to ignore the importance of studying the religious aspects of sport. In light of this, a recent study has sought to encourage sociologists of sport not to divorce the ‘religious’ and the ‘sacred’ from their studies. In response to this call, the goal of the current essay is to explore how the conception of Christianity as ‘public religion’ can be utilized to help justify the use of a Christian sociological approach for studying the social scientific aspects of sport. After making a case for Christianity as public religion, we conclude that many of the sociological issues inherent in modern sport are an indirect result of its increasing secularization and argue that this justifies the need for a Christian sociological approach. We encourage researchers to use the Bible, the tools of Christian theology and sociological concepts together, so to inform analyses of modern sport from a Christian perspective.  相似文献
