Almost half of students who enter college require some sort of remedial coursework. Further, states are increasingly moving the responsibility of postsecondary remediation away from four-year campuses to two-year institutions. Scholars and policymakers have grappled with best practice for successfully filling in academic gaps and moving students forward, and there is variation both within and between states as to the ways in which remediation is defined, determined, and administered (Perin, 2006 Perin , D. ( 2006 ). Can community colleges protect both access and standards? The problem of remediation . Teachers College Record 108 ( 3 ), 339373 .[Crossref], [Web of Science ®] [Google Scholar]). Using a regression discontinuity design, this study seeks to answer the following question on one community college campus: How does placement into remedial services affect student outcomes, in particular, successful completion of an introductory college-level English course? Although this study focuses on a single community college system, the findings have bearing on a wider sector as the developmental placement practices of Harper Community College District are not unlike those implemented by two- and four-year campuses across the country.  相似文献

ABSTRACT

Purpose

To compare the occurrence and characteristics of repeated-sprint (RS) activity in elite team sport competition when classified according to speed and/or acceleration, and their interaction via metabolic power (Pmet). Methods: Elite male hockey players (N = 16) wore player-tracking devices in six international matches. Sprint efforts were defined using four separate classifications: speed >5.5 m?s?1, acceleration >1.5 m?s?2, speed-or-acceleration, and Pmet >25.5 W?kg?1. RS bouts were defined as ≥3 efforts with mean recovery ≤21 s. For Pmet, RS bouts were also classified using a maximal recovery period ≤21 s. The number of sprint efforts and RS bouts, and the number of efforts, effort durations and recovery periods within RS bouts, were compared across each classification method, and between mean and maximal recovery criteria. Results: More RS bouts were identified via Pmet (8.5 ± 2.8) than either speed and/or acceleration, and comprised more efforts (4.0 ± 0.4) with shorter recovery periods (11.5 ± 1.8 s). Fewer RS bouts (7.3 ± 2.8 vs. 8.5 ± 2.8) were identified with a maximum rather than mean recovery criterion. Conclusions: Definitions of sprint efforts and recovery periods which reflect ATP depletion and replenishment via Pmet suggest that RS activity occurs frequently in team sport competition, and is more demanding than when speed and/or acceleration are used to define RS activity in variable-speed locomotion.  相似文献

The study examines the relationship between general knowledge, skills in applying reading strategies, and reading comprehension for ninth‐grade students at varying educational levels: academic, semi‐academic, vocational and learning disabilities. Two hundred and five students received a battery of tests evaluating their general knowledge, skills in applying four reading strategies (summary, self‐questioning, clarification and prediction), and two reading comprehension tests. The findings revealed differential contributions of general knowledge and strategy application to reading comprehension. Compared with the academic students, semi‐academics have deficient strategic skills. Vocational students, in addition to deficient strategic skills, have poor general knowledge, which further impedes their reading comprehension. The deficiency of students with learning disabilities goes beyond these two components. These results led us to recommend different foci of comprehension intervention for each group.  相似文献

This paper addresses the question why socio-technical transitions follow similar trajectories in various parts of the world, even though the relevant material preconditions and institutional contexts vary greatly between different regions and countries. It takes a critical stance on the implicit methodological nationalism in transition studies’ socio-technical regime concept and proposes an alternative ‘global’ regime perspective that embraces the increasingly multi-scalar actor networks and institutional rationalities, which influence transition dynamics beyond national or regional borders. By drawing on globalization theories from sociology and human geography, we show that socio-technical systems often develop institutional rationalities that are diffused via international networks and thus become influential in various places around the world. In so doing, we shed light on the multi-scalar interrelatedness of institutional structures and actors in socio-technical systems and elaborate on the implications for the conceptualization of transition dynamics. The paper illustrates this with the case study of an unsuccessful transition in the Chinese wastewater sector. Recent studies indicate that key decisions on wastewater infrastructure expansion were not only influenced by path-dependencies stemming from China’s national context, but equally (or even more critically) by the dominant rationality of the water sector’s global socio-technical regime. We conclude by discussing the contours of a new research agenda around the notion of global socio-technical regimes.  相似文献

This study aims to investigate the altmetric activity of papers published by the University of Zagreb School of Medicine in internationally visible journals and to identify differences in altmetric activity between the papers published in international and local journals and between those published in English and Croatian. We also investigated changes in altmetric activity over time and the characteristics of papers with the highest Twitter and Mendeley activity.The sample included 390 papers collected from the bibliographic database Scopus. Their altmetric and citation activities were measured at three time points: in July 2014, 2015, and 2016.The findings generally correspond to those observed in the large-scale studies of medical papers. Papers in renowned journals, and papers reporting clinical guidelines and multicentric studies had the most intense altmetric activity. In contrast, papers published in local, Croatian journals showed minimal altmetric activity, especially the papers published in Croatian. These results indicate that the local publishing community has not yet recognised social media as a tool for promoting research and that non-English language publications have minimal chances to receive attention, even in social media.The evaluative potential of altmetric indicators has to be further explored in a broader context.  相似文献

Questions connected with the regulation of one's own cognitive processes attract increasing numbers of researchers in psychology, as evidenced by the several different models of self-regulation that have been developed over the past two decades. The aim of this article was to present and compare the latest models of self-regulated learning (SRL), including those by Boekaerts, Borkowski, Pintrich, Winne and Zimmerman. The models were compared on four criteria (i.e. background theories, definitions of SRL, components included in the models and empirical work). The results show that theoretical background is an important differentiating feature. The two models that resembled each other more than any other two models (i.e. Pintrich and Zimmerman) were inspired by the same background theory (i.e. social cognitive theory). On the other hand, the models that differed most from the other models (i.e. Borkowski and Winne) were also theoretically the farthest removed ones.  相似文献

This qualitative study in a Midwestern US city examines how school and community-based organizations support homeless students’ connections to education-related resources and relationships. Drawing from organizational brokerage theory, which delineates how individuals’ chances to thrive are shaped by the organizations in which they participate, the study finds that brokerage practice unfolds and is affected by variables at three specific levels. First, social workers, teachers, and principals at the individual school level arranged for registration, enrollment, and other immediate connections for students. Second, school district-level actors played key roles in orchestrating homeless students’ transportation and educators’ professional development across the city. Third, a range of neighborhood factors – including immigration and housing trends – affected the ways and extents to which organizations identified and supported homeless students. The study concludes by presenting several implications for research and practice.  相似文献
