As teachers enter the school communities of their initial practice, they experience identity shifts that reflect their learning. Throughout teacher education they have constructed an identity informed by their previous school experiences, the ideas and approaches promoted by their teacher education programs, and an ideal of the teachers they hope to become. The complex set of influences at the boundary between their lives as students and their lives as professionals causes them to confront their identities in new and sometimes disruptive ways (Flores & Day, 2006). New teaching situations introduce them to the thinking of experienced teachers, and to the needs of their first groups of learners, challenging the notions they have so far developed about who they are as teachers (Smagorinsky, Cook, Moore, Jackson, & Fry, 2004). This paper reports on interviews with 35 new teachers as they graduate from teacher education programs and enter the profession, and details their learning about agency and role in community resulting in identity changes within this boundary space.  相似文献

The interactionist model (IM) of human development (R. D. Conger & M. B. Donellan, 2007) proposes that the association between socioeconomic status (SES) and human development involves a dynamic interplay that includes both social causation (SES influences human development) and social selection (individual characteristics affect SES). Using a multigenerational data set involving 271 families, the current study finds empirical support for the IM. Adolescent personality characteristics indicative of social competence, goal-setting, hard work, and emotional stability predicted later SES, parenting, and family characteristics that were related to the positive development of a third-generation child. Processes of both social selection and social causation appear to account for the association between SES and dimensions of human development indicative of healthy functioning across multiple generations.  相似文献

Male and female infants from rural Ethiopia were tested to investigate relations among hemoglobin (Hb), anthropometry, and attention. A longitudinal design was used to examine differences in attention performance from 6 (M = 24.9 weeks, n = 89) to 9 months of age (M = 40.6 weeks, n = 85), differences hypothesized to be related to changes in iron status and growth delays. Stunting (length‐for‐age z scores < ?2.0) and attention performance, t(30) = ?2.42, p = .022, worsened over time. Growth and Hb predicted attention at 9 months, R2 = .15, p < .05, but not at 6. The study contributes to the knowledge base concerning the relations among Hb, early growth, and attention.  相似文献

Wisconsin's influential Learnfare initiative is a conditional cash penalty program that sanctions a family's welfare grant when covered teens fail to meet school attendance targets. In the presence of reference-dependent preferences, Learnfare provides uniquely powerful financial incentives for student performance. However, a 10-county random-assignment evaluation suggested that Learnfare had no sustained effects on school enrollment and attendance. This study evaluates the data from this randomized field experiment. In Milwaukee County, the Learnfare procedures were poorly implemented and the random-assignment process failed to produce balanced baseline traits. However, in the nine remaining counties, Learnfare increased school enrollment by 3.5 percent (effect size = 0.08) and attendance by 4.5 percent (effect size = 0.10). These results suggest that well-designed financial incentives may be an effective mechanism for improving the school persistence of at-risk students at scale.  相似文献

The present study explores Greek parents’ views on parental educational involvement and its impact on adolescent scholastic and social development. Specifically, aspects of parental involvement such as the achieved objectives of current parent–school communication, the psychological climate dominating teacher–parent interactions and parents’ suggestions for improvement of current policies and practices are examined. Four hundred and seventy‐five parents participated in the study. Findings showed that family–school communication is believed to be insufficient in Greece, despite the fact that parents tend to: (1) regard their cooperation with teachers as determinative of adolescent academic and psychosocial development; (2) consider teachers to be friendly and caring; and (3) believe that secondary school provides some opportunities for constructive parental involvement. These paradoxes are discussed and explained as a result of radical changes in current social and educational values, principles and objectives.  相似文献

Most studies of curricular diversity have focused on the effects of participation in diversity courses on student outcomes. Though the results have been positive, these studies have used limited measures of curricular diversity and there is a great need for a complimentary body of research demonstrating what faculty and what types of courses are more likely to include diversity. This study relies on 12 diversity inclusivity items derived from a comprehensive model of how diversity is included into a course to investigate how much diversity is being included in collegiate courses and what predicts diversity inclusivity, as measured by two scales: diverse grounding and inclusive learning. The results, based on 7,101 responses from faculty participating in the 2007 Faculty Survey of Student Engagement, suggest that most faculty are including diversity in their courses in some way, but that women and faculty of color tend to include diversity to a greater extent than their colleagues. Also, courses taught in the soft fields are more likely to be inclusive of diversity.  相似文献

Using data from over 9,000 faculty members that participated in the Faculty Survey of Student Engagement (FSSE), this study examined the moderating role a range of course characteristics played on the effects of gender on the percentage of class time spent on various activities, a measure of teaching style. Results revealed gender differences, but that the gaps between men and women in lecturing and active classroom practices varied by disciplinary area, course level, and the number of times a course had been taught by the same instructor. The results confirm that gender effects depend on context, which implies that efforts to improve teaching and learning must also adapt to the instructional context.  相似文献

In 2004, the University of Michigan Medical School reduced its gross anatomy curriculum. To determine the effect of this reduction on resident perceptions of their clinical preparedness, we surveyed alumni that included residents from the original and new shortened curricula. A Likert-scale survey was sent to four classes of alumni. Respondents were compared in old curriculum (OC) and new curriculum (NC) groups, surgical specialty (SS) and nonsurgical specialty (NS) groups, and subgroups of SS and NS were compared for differences between OC and NC. Mean response scores were compared using independent samples T-tests. As a single population (n = 110), respondents felt their anatomy education prepared them well for residency, that a more robust anatomy curriculum would be helpful, that dissection was important to their residency preparation, and that a 4th year anatomy elective was effective in expanding their anatomy education and preparing them for residency. No significant difference existed between OC and NC groups, neither as a whole nor as SS and NS subgroups. The SS group felt dissection was more important to their residency preparation than the NS group (P = 0.001) and that a more robust anatomy curriculum would have better prepared them for residency (P = 0.001). Thirty percent of SS respondents who did not take a 4th year elective commented that they wish they had. Fourth year anatomy electives were highly valued by residents, and respondents felt that they should be offered to students as a way of revisiting anatomy following the 1st year of clinical training.  相似文献

This award recognizes two specific discoveries that constitute the experimental discovery of neutrino oscillations. In 1998 the Super-Kamiokande group under the leadership of Yoji Totsuka published their paper, “Evidence for Oscillation of Atmospheric Neutrinos” in Physical Review Letters [1]. The paper describes a deficit of muon-type neutrinos from below the detector relative to those from above. It explains this “atmospheric neutrino anomaly” as a result of transformation of some of the muon neutrinos into another type of neutrino. Four years later, the group led by Arthur McDonald described “Direct Evidence for Neutrino Flavor Transformation from Neutral-Current Interactions in the Sudbury Neutrino Observatory” [2] in the same journal. This experiment detected lower energy neutrinos from deep inside the Sun. By measuring all flavors of neutrinos with large rates, the SNO collaboration showed definitively that the long-standing “solar neutrino puzzle” was another manifestation of neutrino oscillations. As a result of these two experiments, we now understand that neutrinos can change identities during propagation and that both the solar and atmospheric neutrino “problems” result from the same underlying phenomenon of oscillations. A consequence of neutrino oscillations is that neutrinos, previously thought to be massless, must have a non-zero rest mass.  相似文献
