The relationships between perceived workplace conditions and morale, career choice commitment, and planned retention were examined for first-year teachers in the United States. A nationally representative sample of first-year teachers (K-12) was extracted from the United States Department of Education's Schools and Staffing Surveys database for 1987–88 and 1993–94. A school culture that supports collaboration and teacher participation in decision-making was most strongly related to higher morale, stronger commitment to teaching, and intentions to remain in the profession. The discussion highlights the importance of providing supportive workplace conditions during a formalized induction year that socialize new teachers into a collaborative and participatory work-ethic that sustains commitment. 相似文献

This article addresses the characteristics, motivations and perceptions of teachers regarding retention. The participants were practicing teachers in Australia. The survey included the Factors Influencing Teaching Choice (FIT-Choice) scale, previously used with preservice teachers. The results show that: i) teacher motivations are related to self-perceptions in teaching children/adolescents in the community, ii) threatened by negative social perceptions, and iii) influenced by characteristics such as gender. It is concluded that retention may be undermined by employment practices and social perceptions that erode a teacher’s self-concept. Outcomes inform policy for improving employment practices for the retention of a diverse teaching workforce. 相似文献

A supportive school environment is crucial to the enhancement of student teaching experiences. This study assesses student teachers' perceptions of secondary school environments, and then relates the perceptions to their satisfaction with school experiences and teaching commitment. The results show that considerable disparities between student teachers' perceptions of actual and preferred school environments and suggest certain directions for improvement. Student teachers' perceptions about their school environments, especially in the areas of professional interest and staff freedom, were positively associated with their satisfaction. Several school environmental aspects influenced the total years they planned to teach and their intention to teach at the placement schools. 相似文献

This study examines the impact of grade retention on behavioral outcomes under a comprehensive assessment-based student promotion policy in New York City. To isolate the causal effect of grade retention, we implement a fuzzy regression discontinuity (RD) design that exploits the fact that grade retention is largely determined by whether a student scores below a cutoff on a standardized test score. We use data on students subject to the policy over a nine-year span to examine impacts on attendance and disciplinary event outcomes. We do not find evidence of systematic effects of retention on behavioral outcomes in either direction. We do find sporadic nonsustained significant effects of retention on behavioral outcomes. When present, these isolated nonpersistent effects tend to be beneficial when found for retained elementary school students and mixed for retained middle school students. 相似文献

Early withdrawal from higher education (HE) programmes can be detrimental for the students and institutions involved. Quantitative research has often concentrated on demographic and social antecedents (e.g. gender, prior education). Other factors may be more open to intervention e.g. students’ academic experiences in HE. Using data from an institutional survey (N?=?1170), logistic regression tested a range of academic experiences, regarding their relationship to contemplation of withdrawal (‘COW’: a recognised marker for actual withdrawal). COW was associated with student perceptions of low one-to-one contact with staff; non-traditional delivery methods; low peer-interaction; and high assessment load. Interestingly, COW was not associated with overall contact hours, large classes, or personal tutoring. The contributing factors explained 5.1%–8.6% of variance in COW, suggesting they may be meaningful levers for optimising retention. The paper discusses links to existing literature, future research directions, and applied implications for institutions. 相似文献

For most teachers in the United States, teaching is no longer a career-long occupation. This article examines the narratives of a particular group of leavers, former teachers who made significant investments in their teacher training and who taught for at least three years before making the decision to exit. The accounts of these invested leavers are used to look at workplace change as a motivating factor for teacher exit, particularly changes in classroom authority that occur after teachers have begun to feel competent. 相似文献
