In recent years, many U.S. states have introduced growth models as part of their educational accountability systems. Although the validity of growth‐based accountability models has been evaluated for the general population, the impact of those models for English language learner (ELL) students, a growing segment of the student population, has not received sufficient attention. We evaluated three commonly used growth models: value tables or transition matrices, projection models, and student growth percentiles (SGP). The value table model identified more ELL students as on track to proficiency, but with lower accuracy for ELL students. The projection and SGP models were more accurate overall, but classified the fewest ELL students as on track and were less likely to identify ELL students who would later be proficient. We found that each model had significant trade‐offs in terms of the decisions made for ELL students. These findings should be replicated in additional state contexts and considered in the development of future growth‐based accountability policies. 相似文献

Although romantic and sexual relationships are an important aspect of young people's lives, research on how young people negotiate their love/sex relationships is lacking. New media environments provide a new context within which young people negotiate their love/sex relationships; however, what is negotiated is often not all that different from what was negotiated before the advent of new media technologies. Using an online discussion board and individual in-person interviews, this paper explores how young Australians, aged 18–25 years, engage with dominant gendered discourses to negotiate their love/sex relationships within the context of new media environments. Previous research suggests that young people make use of new media technologies to flirt with one another, to initiate new relationships, to maintain their relationships, and to fight and end their relationships. This paper focuses on young people's practices of mediated flirting, surveillance, and breaking up. It considers the creative and agentic ways young people use new media technologies in the negotiation of their love/sex relationships. 相似文献

We use the 2003 National Survey of College Graduates to provide the first estimates of the effect on earnings of having a double major. Overall, double majoring increases earnings by 2.3% relative to having a single major among college graduates without graduate degrees. Most of the gains from having a double major come from choosing fields across two different major categories. Graduates who combine an arts, humanities or social science major with a major in business, engineering, science or math have returns 7–50% higher than graduates with a single major in arts, humanities or social science. But such double major combinations have returns no higher than single majors in business, engineering, science or math. Majors combining business and science or math have returns more than 50% greater than the returns to having a single major in these fields. 相似文献

This study examined the contributions of the different components of the working memory (WM) model to a range of mathematical skills in children, using measures of WM function that did not involve numerical stimuli. A sample of 148 children (78 Year 3, mean age 8 years and 1 month, and 70 Year 5 pupils, mean age 9 years and 10 months) completed WM measures and age‐appropriate mathematics tests designed to assess four mathematical skills defined by the National Curriculum for England. Visuo‐spatial sketchpad and central executive, but not phonological loop, scores predicted unique variance in children’s curriculum‐based mathematical attainment but the relative contributions of each component did not vary much across the different skills. Subsequently, the mathematics data were re‐analysed using cluster analysis and new performance‐related mathematics factors were derived. All three components of WM predicted unique variance in these performance‐related skills, but revealed a markedly distinct pattern of associations across the two age groups. In particular, the data indicated a stronger role for the visuo‐spatial sketchpad in the younger children’s mathematics performance. We discuss our findings in terms of the importance of WM in the development of early mathematical ability. 相似文献

Within the natural sciences and engineering, literature relating to postgraduate education, in particular the process of completing a doctorate, remains generally scarce. That which does exist emphasises the role of the supervisor in effecting successful completion and points to a wide range of activities performed by supervisors. There remains, however, little by way of accounts of the actual experiences of supervisors or students when engaged in the process of doctoral supervision. It is these experiences which form the basis of this paper which focuses upon doctoral students and their supervisors in the disciplines of physics, mathematics and engineering science. Data for the paper have been collected, as part of an ESRC funded project, by means of in‐depth interviews with students and supervisors in nine universities in England. In particular, we address students expectations of PhD supervision, the extent to which expectations have been met, and within the context of the ‘career’ of the PhD, the ways in which supervision changes as the doctoral process progresses. Important issues relating to the need for training for PhD supervisors and their capacity to meet the expectations of their students are raised, together with those which question the relationship between the PhD and the culture of academic work. 相似文献

The effectiveness of having students generate their own headings for scientific text is assessed. Results reveal that generating headings enhance performance on a number of recall measures compared to either author-provided headings or no headings. Educational implications are discussed. 相似文献
