Reading is typically considered a survival skill in our technology- and literacy-bound culture. Individuals who struggle with learning to read are at significantly elevated risk for a number of negative outcomes, including school failure, under- and unemployment, and special education placement. Thus, those who do not learn to read fluently will likely be a greater drain on society's resources. The authors examined the effects of a universal (school district-wide) implementation of a well-validated peer-tutoring reading intervention as a system-wide prevention measure in kindergarten through Grade 3 in a small metropolitan area in Canada. Results suggest that nearly all children demonstrated improved reading fluency over time. Yet those at highest-risk for poor outcomes, including those living in poverty and those who face learning challenges due to English as a second-language status or special education enrollment, did not make parallel gains to same-age peers in more affluent schools. Implications for educational policy are discussed. 相似文献

As a field, we have a limited understanding and a dearth of empirical research concerning the role of high school instructional coaches focused on English learners (ELs). This paper examines one EL facilitator’s work as an instructional coach and resource for supporting mainstream content teachers as they learn to meet the needs of adolescent ELs in one high school. This analysis is grounded within an examination of the influence of school structure and organization on the EL facilitator’s work and her role as a resource. Drawing on sociocultural learning theory, as well as literature on teacher leadership and instructional coaching, case study data from a year-long qualitative research project are analyzed. Implications for research, policy, and practice are discussed. 相似文献

This paper explores the experiences and perceptions of a little-known category of in-service trainee teachers in the Further Education (FE) and Skills sector in England: those who meet the practical teaching requirements of their course mainly through unpaid teaching as ‘volunteers’. The paper reports findings from mixed-methods research which used surveys, interviews and focus groups involving trainee teachers within a large FE–HE partnership. Themes relating to motivations to volunteer, the development of teacher identity within marginal roles, and the risks associated with unpaid teaching are discussed. For increasing numbers of trainees, unpaid teaching provides an opportunity for career entry. However, the quality of teaching experience gained is mixed, with some trainees receiving high levels of support, whilst others experience marginalisation and limitations on their developing teacher identities. The paper highlights the specific challenges to professionalism posed by unpaid teaching within the FE and Skills sector, and relates these challenges to a broader context of insecurity and risk. As work experience becomes an increasingly valuable commodity, this paper illustrates the pressures individuals face as they exchange payment and security for the opportunities volunteering provides. 相似文献

Over the past 20 years, the USA has seen more than its fair share of controversy with respect to education about sexuality, sex and intimate relationships. Attention has focused on content (abstinence-only vs. comprehensive instruction), delivery (by teachers, parents, health professionals or community educators) and context (within school and beyond). In recognition of this fact, Sex Education invited the development of a virtual special issue comprising a sample of its most impactful papers on these and related topics. The 2016 Presidential election results and recent legislative action in the USA point to the importance of thinking broadly about teaching and learning about sexuality inside and outside of schools and of considering sexuality as it intersects with categories of difference, privilege and penalty, including ability, age, immigration, race, gender and class. This paper, developed as an introduction to the virtual special issue, opens with a discussion of the journal’s contributions to the ongoing discussion of pleasure and desire in sexuality education. From there, we turn to the question of what is possible given the material and ideological conditions of schooling and then to opportunities for teachers and learners outside the conventional classroom. We follow with a discussion of the place of intersectional analyses in sexuality education research, and conclude with some thoughts on sexuality education research at this political moment. 相似文献

My avatar,my self: Virtual harm and attachment 总被引:1,自引:0,他引:1
Jessica Wolfendale 《Ethics and Information Technology》2007,9(2):111-119
Multi-user online environments involve millions of participants world-wide. In these online communities participants can use
their online personas – avatars – to chat, fight, make friends, have sex, kill monsters and even get married. Unfortunately
participants can also use their avatars to stalk, kill, sexually assault, steal from and torture each other. Despite attempts
to minimise the likelihood of interpersonal virtual harm, programmers cannot remove all possibility of online deviant behaviour.
Participants are often greatly distressed when their avatars are harmed by other participants’ malicious actions, yet there
is a tendency in the literature on this topic to dismiss such distress as evidence of too great an involvement in and identification
with the online character. In this paper I argue that this dismissal of virtual harm is based on a set of false assumptions
about the nature of avatar attachment and its relation to genuine moral harm. I argue that we cannot dismiss avatar attachment
as morally insignificant without being forced to also dismiss other, more acceptable, forms of attachment such as attachment
to possessions, people and cultural objects and communities. Arguments against according moral significance to virtual harm
fail because they do not reflect participants’ and programmers’ experiences and expectations of virtual communities and they
have the unintended consequence of failing to grant significance to attachments that we take for granted, morally speaking.
Avatar attachment is expressive of identity and self-conception and should therefore be accorded the moral significance we
give to real-life attachments that play a similar role.

Individuals with autism spectrum disorder (ASD) show differences in face processing abilities from early in development. To examine whether these differences reflect an atypical versus delayed developmental trajectory, neural responses to familiar and unfamiliar faces in twenty-four 18- to 47-month-old children with ASD were compared with responses of thirty-two 12- to 30-month-old typically developing children. Results of 2 experiments revealed that neural responses to faces in children with ASD resembled those observed in younger typically developing children, suggesting delayed development. Electrophysiological responses to faces were also related to parent report of adaptive social behaviors for both children with ASD and typical development. Slower development of the face processing system in ASD may be related to reduced self-directed "expected" experience with faces in early development. 相似文献

Despite the many benefits of involving undergraduates in research and the growing number of undergraduate research programs,
few scholars have investigated the factors that affect faculty members’ decisions to involve undergraduates in their research
projects. We investigated the individual factors and institutional contexts that predict faculty members’ likelihood of engaging
undergraduates in their research project(s). Using data from the Higher Education Research Institute’s 2007–2008 Faculty Survey,
we employ hierarchical generalized linear modeling to analyze data from 4,832 science, technology, engineering, and mathematics
(STEM) faculty across 194 institutions to examine how organizational citizenship behavior theory and social exchange theory
relate to mentoring students in research. Key findings show that faculty who work in the life sciences and those who receive
government funding for their research are more likely to involve undergraduates in their research project(s). In addition,
faculty at liberal arts or historically Black colleges are significantly more likely to involve undergraduate students in
research. Implications for advancing undergraduate research opportunities are discussed. 相似文献

Research on categories and markets suggests that audiences rely on categorical distinctions to make sense of market offerings. Market offerings that deviate from category norms risk devaluation. Although literature in this area has led to valuable insights, scholars have begun to question whether there has been an overemphasis on conformity, leaving existing theories ill-equipped to account for innovation. Within this context, we argue that research on authenticity in cultural sociology offers a useful platform for theorizing. We draw on the work of Peterson (1997), who underscores the importance of signals in evaluation. Objective features of market offerings (e.g., quality) matter, but particularly for innovations, these features are not readily visible. Because authentic producers are typically thought to be more committed, capable, and intrinsically motivated, when visibility of such objective features is lacking, authenticity may serve as an alternative indicator of value. Appearing authentic requires signaling believability with respect to category norms, while also being distinctive. Using data on 684 firms from five high technology sectors, we explore the relationship between authenticity and investor perceptions of value. Focusing on three different proxies for signals of authenticity—networks, governance, and narratives—we find a curvilinear association between conformity/distinctiveness and Tobin's q. Consistent with our view of authenticity as a signal, we also find that this relationship flattens as firms gain better track records and face stiffer competition. 相似文献
