This paper describes the results of a replication of a study testing the predictive validity of a 34-item instrument designed to assess the fundamental constructs of Tinto's model of college student attrition. A design, variables, and analytical procedures virtually identical to those of the original study (done at a large independent university) were used, and this research was conducted at a large public university. The five-factor structure, found in the original study to underlie the 34 items, was replicated almost exactly. As in the earlier work, the Institutional and Goal Commitment Scale was a significant predictor of attendance behavior even after controlling for a variety of students' precollege characteristics. Potential institutional differences in faculty members' influence on retention were identified. A cross-validation classification procedure suggests the five factors are reasonably stable predictors of attrition.An earlier version of this paper was presented to the annual conference of the American Educational Research Association, Boston, April 1980.  相似文献

This study investigated differences in student perceptions of the institutional climate associated with sex, year of enrollment, and the interaction between these two variables. Consistent with previous research, freshmen at both institutions sampled had significantly higher ratings of the climate on an intellectualism/scholarship factor than seniors. On two factors, identified as responsiveness and openness, a significant interaction effect was indicated between sex and class. No significant differences were noted between freshmen men and women; however, senior women were found to have significantly lower mean ratings on these two dimensions than senior men. Thus as length of exposure to the institution increased (comparing freshmen with seniors) assessments of the environmental press by male and female students tended to diverge.  相似文献

The authors conducted a treatment outcome study on 79 patients engaged in a program for maltreating parents. Treatment modalities included individual psychotherapy and counseling, group therapy, home visiting, and telephone advocacy with the duration of treatment ranging from 6 sessions to 36 months. On the basis of ratings by the primary therapist consensually validated by other staff, 23 of the sample demonstrated at least symptomatic improvement, whereas 28% improved significantly. Overall improvement was highly correlated with more subtle indices of childrearing, perception of the child, object relations, insight, and capacity for self-observation. The profiles of those maltreating parents who improved and those who did not emerged with respect to the impact of critical demographic, psychological, and therapeutic variables. Favorable outcomes were unlikely among parents who themselves had a history of maltreatment, who inflicted the more severe injuries, who entered the program involuntarily or who terminated against advice; while positive results were more prevalent in those parents with a less abusive childhood experience and who perceived a need for involvement in the program. Home visiting and advocacy appeared to enhance the potential for improvement.  相似文献

The current study addresses student perceptions of math and science professors in the Middle East. Gender disparity in science, technology, engineering, and math (STEM) education continues to exist in higher education, with male professors holding a normative position. This disparity can also be seen in the United Arab Emirates. As female participation in STEM education lags behind men, it is possible that gender stereotypes may influence students’ first impressions of male and female instructors. The United Arab Emirates provides a unique context to study this phenomenon as it is a traditional patriarchal society that is highly dependent on the engineering discipline, especially within the oil and gas sectors. A total of 176 undergraduate students from 2 universities in the United Arab Emirates completed a survey about teaching effectiveness based on their perceptions of photographs of hypothetical male and female instructors. A factor analysis of survey items revealed 2 main subcategories of teacher effectiveness: namely teacher warmth and professionalism. A 2-way between-groups analysis of variance was conducted to explore the impact of teacher gender and student gender on perceptions of overall teaching effectiveness, as well as their perceptions of teacher warmth and professionalism. Findings revealed that there was a significant cross-gender effect on student perceptions of math and science instructors in the United Arab Emirates.  相似文献

The role that governments play in higher education systems in the western world is being generally criticized. Most studies on desirable future models show that most of the experts and individuals involved favour a reduction in government influence. At the same time, however, governments are ‐ in publicly‐funded higher education systems ‐ accountable to the public for the funds allocated to the institutions, and are held responsible for a number of (political) aims and goals associated with higher education policy. This article considers which type of relationship between governments and higher education systems might be considered to be the most prominent for the future. It combines critical signals on the present methods, on the one hand, and the generally accepted responsibilities of governments, on the other, in a multi‐criteria analysis. Contrary to the general outcome of studies on governance, the participants in the study have opted for a relatively orthodox scenario in which governments remain influential actors with regard to higher education policies.  相似文献

Given that schools are, potentially, powerful sites for influencing adolescent behaviour, it is important that there is greater understanding of the psychosocial aspects of the school climate that can be leveraged for this purpose. The research reported in this article used structural equation modelling (with data from a sample of 6120 students at Australian high schools) to examine the influence of the psychosocial school-level environment on students’ self-reported experiences of bully victimisation (i.e. being victims of bullying) and engagement in delinquent behaviours. Further, we examined whether bully victimisation mediated the relationships between school climate variables and delinquent behaviours. School connectedness and rule clarity were negatively associated with both bully victimisation and delinquency (p < 0.05), and teacher support was negatively associated with bully victimisation (p < 0.01), confirming the importance of these aspects of the school-level environment. However, affirming diversity and reporting and seeking help both had positive influences on bully victimisation (p < 0.05), raising concerns about the ways in which these aspects of the school-level environment might have been promoted. Importantly, bully victimisation was found to mediate the influence of five of the six school climate constructs on delinquent behaviours (p < 0.001). This study advance our understanding of how specific aspects of the school climate influence the prevalence of bullying and delinquent behaviour, adding weight to the call for educators to actively monitor and enhance psychosocial aspects of the school climate in order to improve student behavioural outcomes.  相似文献

The effects of college tuition costs on early career educational, occupational and economic achievements were estimated for a national sample of black and white college students. The findings suggest that attending a relatively high tuition college has a net positive influence on such outcomes as educational attainment, occupational status, income and women's entry into sex-atypical careers. These effects remained significant even when controls were made for student background characteristics (e.g., socioeconomic origins, secondary school achievement, educational and occupational aspirations); the academic selectivity, private/public control, size and graduate orientation of the college attended; and one's specific college experiences (e.g., academic major, academic achievement and social involvement). The findings are discussed in terms of several plausible causal mechanisms.  相似文献

The paper discusses multilinear, and more generally multidecomposable, machines. An m-linear machine is shown to be realizable as a network of k-linear machines for k?(m-1), linked by certain memoryless m-linear maps. In this way, an m-linear machine can be broken down into linear machines and multilinear memoryless maps.  相似文献

Long-term persistence of two-year college students   总被引:2,自引:2,他引:2  
This paper employs a theoretical model to explain the long-term persistence of students who began their postsecondary education in two-year institutions. The model was estimated on a national sample of 825 students who initially enrolled in 85 two-year institutions in the fall of 1971, and who were followed over a nine-year period. Although there were differences in the factors associated with persistence for men and women, the results tend to confirm the importance of person-environment fit as a salient influence on degree persistence and completion in postsecondary education. Measures of academic and social integration had the most consistent pattern of positive direct effects, and much of the influence of student precollege traits was indirect.  相似文献

In recent years, many academic libraries have started adopting social media by, for example, establishing their own Facebook pages. Our research investigates the current Facebook usage among seven university libraries in Hong Kong. Using a mixed-method research approach, we examined the characteristics of academic libraries Facebook usage and its effectiveness to engage with their patrons, based on online observations and Web content analysis from the publicly available data of the Facebook pages.Our results indicated that most libraries in Hong Kong adopted Facebook as a marketing tool, yet the user engagement level in these pages is low. In addition, we also discovered that communication-related posts and video-type posts can attract the most attention of patrons. Based on these outcomes, we provided some recommendations on the application of Facebook for academic libraries.  相似文献
