In 2007, Tulsa Community College (TCC) joined the national Achieving the Dream (ATD) network, which is dedicated to developing data-informed interventions to increase persistence and completion among community college students. TCC’s participation in the national initiative set it down a path for positive institutional change, but it was the College’s restructuring of their internal work teams and their process improvements since 2011–2012 that have resulted in a sustainable system that will help retain knowledge and ensure successful leadership transitions. In 2013, TCC rebranded its modified ATD system as Completing the Dream, combining the goals of Complete College America with the action research principles of Achieving the Dream. Because of these efforts, the College is in a stronger position today than it has ever been to serve our students using evidence-based strategies, ultimately resulting in more college-educated citizens in the Tulsa area.  相似文献

In the wake of Hurricane Katrina, Mississippi Gulf Coast superintendents were faced with changes in their communities, schools, and school districts of a magnitude that they could not have imagined. This narrative study was based on multiple interviews conducted in 2005 and 2006 of 7 Gulf Coast superintendents. The study investigated how these superintendents have responded to the devastation of Katrina and how they perceive their leadership roles to have changed as a result. The study found that the superintendents have changed their priorities and focuses and have drawn on their personal strength and resilience to serve the people in their school districts and their communities.  相似文献

Research Findings: Using observational data gathered in 730 kindergarten classrooms in 6 states, the present study focuses on the quality of children's learning opportunities in kindergarten classrooms. Findings show that overall, children experience moderate to low levels of quality in the areas of classroom organization and instructional support in kindergarten. Results are also presented in comparison to children's experiences in the pre-kindergarten year. These comparisons indicate that kindergarten children spend a greater proportion of the school day in language arts, math, and whole-group instruction and less time in centers than they do in pre-kindergarten. An examination of predictors of kindergarten classroom quality indicated that program characteristics (i.e., adult–child ratio, length of school day) and teacher psychological variables (i.e., beliefs and depressive symptoms) were stronger predictors of classroom quality than were teacher experience and educational background. Practice or Policy: Findings are discussed in terms of implications for children's academic and social development in kindergarten as well as for kindergarten teacher preparation and development.  相似文献

Consultation is a promising approach to creating change in early childhood programs, from innovations in instructional strategies to the enhancement of global program quality. Studies of consultation effectiveness have been hampered by limited reports of implementation fidelity related to consultation procedures. This article describes the challenges of supporting and measuring implementation fidelity in a 5-state study in which community consultants followed a collaborative consultation model to enhance global quality in childcare programs. The authors consider the limitations of using a randomized experimental design to study the effectiveness of consultation and share lessons learned in their efforts to enhance treatment fidelity without compromising the basic tenets of the model or the rigorous design.  相似文献

Teacher candidates train in an educational world that has changed dramatically. The tensions and challenges that preservice teachers experience are a reality for teacher education programs and must be planned for. The authors from a teacher preparation program describe the steps they have taken to support more authentic and integrated work with teacher candidates who struggle in their performance during their licensure program. After implementing a program‐wide support plan protocol and professional action plan tool, we examined the issues that signaled the need for intervention, the types of supports provided, and the resulting program decision. We captured staff perspectives regarding the effectiveness of the support plan protocol and conclude with recommendations to support teacher candidates in acquiring the conceptual and technical knowledge, skills, and disposition needed to teach in today’s classrooms.  相似文献

This research project began as an effort to redesign a learning theory course as transitional space and evolved into an analysis of how unresolved conflict from younger learning selves influence graduate preservice teachers’ acquisition of teacher identity. The study draws upon work by Elizabeth Ellsworth on transitional space and Deborah P. Britzman’s work that deconstructs teacher education development. The data for the study were collected throughout a three‐semester graduate teacher education program and include narrative and formal writing using theoretical discourses. Foucauldian concepts of discourse analysis were used to interpret the initial data set; discourse analysis maps were then employed to further develop data interpretation. Two case study illustrations of preservice teachers resulted from this work. These illustrations demonstrate how transitional space is troubled space and the unevenness of teacher development. The study raises the question, ‘What will teacher education do with uncertainty?’  相似文献

The purpose of this research was to determine whether the young child's understanding of physical causality is affected by school science instruction. Sixty-four subjects, four and one-half through seven years of age, received 300 min of instruction designed to affect the subject's conception of causality as reflected in animism and dynamism. Instruction took place for 30 min per day on ten successive school days. Pretesting was done to allow a stratified random sample to be based on vocabulary level and developmental stage as well as on age and gender. Post-testing consisted of testing of developmental level and level within the causal relations of animism and dynamism. Significant differences (1.05 level) were found between the experimental and control groups for animism. Within the experimental group, males differed significantly (1.001 level) from females. The elimination of animism appeared to have occurred. For dynamism, significant differences (0.05 level) were found only between concrete operational subjects in the experimental and control groups, indicating a concrete level of operations was necessary if dynamism was to be affected. However, a review of interview protocols indicated that subjects classified as nonanimistic had learned to apply a definition rather than to think in a nonanimistic manner.  相似文献

This study sought to discover some of the causes of initial interset in and atrition from the natural sciences and engineering among the students (N=5320) who entered four highly selective institutions in 1988, with particular attention to possible special causes for the disproportionate attrition of women from science. Though a smaller proportion of women (35 percent) than men (49 percent) were initially interested in science, gender added little to the prediction of such initial choice when preadmission measures of developed abilities were taken into account in regression analysis. Of the group of 2,276 students initially interested in science, 40 percent did not finally concentrate in science, and smaller proportions of women (48 percent) than of men (66 percent) persisted. The most significant cognitive, factor predicting these losses was low grades earned in science courses taken during the first two years of study. With grades held equal, gender was not a significant predictor of persistence in engineering and biology; gender added strongly to grades, however, as a factor associated with unusually large losses of women from a category that included the physical sciences and mathematics. Responses to a questionnaire administered in the fall of 1991 showed that science majors regarded their instruction as too competitive, with too few opportunities to ask questions, taught by professors who were relatively unresponsive, not dedicated, and not motivating. Students who defected from science did so largely because of the attraction of other fields, but many shared the criticism of overcompetitiveness and inferior instruction, along with the view that the work was too difficult. Several items were about elements of classroom instruction and atmosphere thought to be especially difficult for women (i.e., the chilly climate), but except for perceived competitiveness, women did not rate their classroom experiences as being more unpleasant than did men. This research was supported by grants from the Alfred P. Sloan Foundation and the National Science Foundation.  相似文献
